Frequently Asked Questions

Chain-Fi is an enterprise-grade Web3 security ecosystem providing a complete suite of security solutions through a subscription-based model with gasless transactions. It includes identity management, OAuth authentication, multi-signature vaults, and mobile 2FA across multiple blockchain networks.

The Chain-Fi ecosystem consists of four integrated products: Chain-Fi Vault (multi-sig asset protection), Chain-Fi Identity (unified Web3 identity with KYC), Chain-Fi OAuth (user-controlled authentication for dApps), and Chain-Fi Mobile App (airgapped 2FA device). One subscription gives you access to all products.

Unlike traditional wallets where you pay gas per transaction, Chain-Fi offers subscription-based gasless transactions. You also get a complete ecosystem (identity + OAuth + vault + mobile 2FA) instead of just a wallet. Chain-Fi is the Spotify/Netflix of Web3 security - predictable monthly fee, unlimited usage within your tier.

Chain-Fi is enterprise-grade because it provides: 1) Multi-signature vaults with three-address protocol requiring multiple device approvals, 2) Airgapped mobile 2FA that operates offline for maximum security, 3) Audited smart contracts deployed across multiple blockchain networks, 4) KYC integration for compliance, 5) Real-time threat detection and monitoring, 6) API access for enterprise integrations, 7) Priority support and dedicated account management. This combination provides institutional-level security for both individual users and organizations.

Chain-Fi is non-custodial. You maintain full control of your private keys and assets. The platform never holds your funds - they remain in your multi-signature vault smart contracts on the blockchain. Chain-Fi only provides the security infrastructure, transaction relaying for gasless transactions, and identity management services. Your assets are always under your control with multi-signature protection.

Gasless transactions only apply when you interact with dApps or platforms using Chain-Fi vault transactions. With Chain-Fi, your membership tier includes monthly credits, and the platform covers all gas fees for vault-based transactions up to your credit limit. Transaction credits are consumed based on network: Layer 2 networks (Base, Arbitrum, Optimism, Polygon) = 1 credit per transaction. Ethereum mainnet (Enterprise tier) = 5 credits per transaction. If you use your bound wallet directly (outside of Chain-Fi vault transactions), you pay normal gas fees like any regular wallet. The platform uses meta-transactions and a relayer network to pay gas fees on your behalf for vault transactions only.

If you exceed your monthly transaction credit limit, you have several options: 1) Purchase additional credit packages on request (one-time purchase), 2) Wait until your credits reset at the start of the next month, 3) Use your vault for deposit/withdraw operations which don't consume credits (only gasless transactions require credits). Unused credits do not roll over to the next month. Credit packages can be purchased on request and credits can be used on any chain. Note: $GUARD token payments may be available in the future if and when the token launches, but only after all product milestones are met.

Gasless transactions are available for vault transactions on all supported networks, but credit consumption varies: Layer 2 networks (Base, Arbitrum, Optimism, Polygon) consume 1 credit per transaction regardless of tier. Ethereum mainnet consumes 5 credits per transaction and is only available on the Enterprise tier due to higher gas costs. Basic tier users can only use gasless transactions on Base network. Premium tier users can use all L2 networks. Enterprise tier users have access to all networks including Ethereum mainnet. Important: Gasless transactions only apply to Chain-Fi vault transactions. If you use your bound wallet directly (not through Chain-Fi vault), you pay normal gas fees regardless of your subscription tier.

Chain-Fi uses a relayer network and meta-transaction architecture. When you initiate a transaction, it's signed by your wallet but submitted to Chain-Fi's relayer network. The relayer pays the gas fee and executes the transaction on-chain. This is made possible through EIP-712 meta-transactions and a network of trusted relayers. The platform maintains sufficient ETH reserves across all supported networks to cover gas costs for all users' transactions within their credit limits.

No, there are no hidden fees. Your membership tier includes monthly credits that cover gas fees up to your credit limit. The only costs are: 1) One-time membership purchase (includes vault deployment, KYC verification with 1 year validity, and monthly credits), 2) Optional credit packages purchased on request if you need additional credits. There are no per-transaction fees, no gas fee markups, and no hidden charges. All pricing is transparent and upfront.

Chain-Fi supports Ethereum mainnet, Base (Coinbase L2), Arbitrum (Optimistic Rollup), Optimism (Optimistic Rollup), and Polygon (PoS Chain). The number of networks you can use depends on your membership tier: Basic (Base only), Premium (all L2 networks: Base, Arbitrum, Optimism, Polygon), Enterprise (all networks including Ethereum mainnet).

Yes! Premium and Enterprise tier users can deploy vaults and use Chain-Fi services across multiple blockchain networks simultaneously. You can have separate vaults on Base, Arbitrum, Optimism, and Polygon, all managed from a single Chain-Fi dashboard. Your Chain-Fi Identity and KYC verification work across all networks, so you don't need to repeat verification for each chain. Enterprise tier users can also access Ethereum mainnet in addition to all L2 networks.

Yes, Chain-Fi regularly adds support for new blockchain networks based on user demand and market trends. Popular networks being considered include Solana, Avalanche, BNB Chain, and other Layer 2 solutions. Users are notified when new networks become available, and existing users can deploy vaults on new networks without additional setup fees. The platform is designed to be chain-agnostic and can integrate with any EVM-compatible or non-EVM blockchain.

Yes, Chain-Fi supports cross-chain asset management. You can view your portfolio across all connected networks in a unified dashboard. However, actual cross-chain transfers require bridge protocols. Chain-Fi integrates with major bridges and can facilitate cross-chain transactions using your gasless transaction credits. The platform provides a seamless interface for managing assets across multiple chains, even if the assets themselves remain on their native chains.

Basic ($3.50/month) includes 50 gasless transactions on Base network only. Premium ($7.50/month) includes 150 gasless transactions across all L2 networks (Base, Arbitrum, Optimism, Polygon). Enterprise ($15/month) includes 1,000 gasless transactions, all networks including ETH mainnet, API access, and priority support. All tiers unlock credit-based ecosystem features. Note: Dashboard access, vault (deposit/withdraw), Identity, OAuth, and Mobile App are available during your first free year after setup fee. Monthly subscription for credit-based features can be added immediately to your account if you want gasless transactions right away.

The free account lets you: download the app, create your profile, connect the app to your profile, explore your dashboard, and join our community. The paid setup (one-time membership purchase) unlocks: vault deployment on the blockchain, KYC verification for identity (1 year validity), full access to all Chain-Fi modules (Identity, OAuth, Mobile App), monthly credits included, and 1 year membership with full dashboard access, vault deposit/withdraw capabilities, and all modules. Your membership includes monthly credits for gasless transactions, so no additional subscription is needed.

The one-time setup fee covers vault deployment, KYC verification, and includes your first year free. This fee creates and deploys your multi-signature vault on the blockchain, processes your identity verification, and gives you 12 months of free access to: dashboard access, vault metrics, deposit/withdraw capabilities, and full access to all other Chain-Fi modules (Identity, OAuth, Mobile App). Credit-based ecosystem features (gasless transactions) require a monthly subscription tier, which can be added immediately to your account if you want to use gasless transactions right away.

Your one-time membership purchase includes: vault deployment, KYC verification (1 year validity), 1 year membership with full access to dashboard, vault metrics, the ability to deposit and withdraw assets from your vault, monthly credits for gasless transactions, and full access to all Chain-Fi modules (Identity, OAuth, Mobile App) for 12 months. All membership tiers include monthly credits, so gasless transactions are available immediately with your membership.

Chain-Fi offers three membership tiers, each a one-time purchase for 1 year membership: Basic tier - For individual users starting with Chain-Fi, includes Base chain only, 10 credits/month, KYC verification (1 year validity), and full ecosystem access. Premium tier - For users who need full multichain protection, includes all supported chains, 50 credits/month, KYC verification (1 year validity), and full ecosystem access. Enterprise tier - Custom packages for founders, teams & high-security users, includes 1,000+ credits/month, KYC/KYB verification (1 year validity), all networks including ETH mainnet, API access, and priority support. All tiers include monthly credits and full access to all Chain-Fi modules.

Membership tiers are purchased for a 1-year period. If you need to upgrade or change your tier, you can purchase a new membership tier. Your data, identity, wallet bindings, and vault remain intact when changing tiers. If you need additional credits beyond your monthly allocation, you can purchase credit packages on request (one-time purchase) that can be used on any chain.

Chain-Fi accepts multiple payment methods: 1) Stripe (credit/debit cards) - Available now for membership purchases and credit packages, 2) Ethereum (ETH) - Pay directly with ETH for membership purchases and credit packages. All payment methods are secure and processed immediately. Membership purchases can be paid with Stripe or ETH. Credit packages can be purchased on request using Stripe or ETH. Note: $GUARD token payments may be available in the future if and when the token launches, but only after all product milestones are met and the token provides clear utility to the Chain-Fi product.

Chain-Fi offers a 30-day money-back guarantee for membership purchases if you're not satisfied with the service. However, KYC processing costs are non-refundable as they're paid to third-party verification services. Credit packages purchased on request are non-refundable once purchased. Refunds are processed within 5-10 business days to your original payment method.

Yes. Chain-Fi uses a three-address protocol with multi-signature protection. Your assets are secured by audited smart contracts, and all transactions require approval from multiple devices including your airgapped mobile app. Even if one device is compromised, your assets remain secure.

The three-address protocol requires three separate addresses to approve vault transactions: 1) Your primary wallet address (from your connected wallet like MetaMask), 2) Your Chain-Fi address (managed by the platform), 3) Your mobile 2FA signature (from your airgapped Chain-Fi app). All three must approve before any asset can be moved from your vault. This means even if your computer is hacked, your phone is stolen, or the platform is compromised, your assets remain secure because an attacker would need access to all three components simultaneously.

If you lose your mobile device, you can immediately unpair it from your Chain-Fi account using your password and primary wallet signature. Then pair a new device by downloading the Chain-Fi app and scanning the QR code from your dashboard. Your vault assets remain secure during this process because the three-address protocol still requires your primary wallet signature. You should unpair the lost device as soon as possible to prevent unauthorized access attempts, though the device cannot access your account without your password and wallet signature.

Yes, all Chain-Fi smart contracts undergo comprehensive security audits by reputable blockchain security firms before deployment. The vault contracts, identity contracts, and OAuth contracts are all audited and verified. Audit reports are available upon request for Enterprise tier users. The platform also participates in bug bounty programs to encourage responsible disclosure of any security vulnerabilities. All contracts are open-source and can be reviewed on GitHub.

Chain-Fi is a non-custodial platform, meaning your funds are held in smart contracts on the blockchain, not in Chain-Fi's custody. As such, traditional insurance doesn't apply. However, the platform provides enterprise-grade security through: 1) Audited smart contracts, 2) Multi-signature protection requiring three approvals, 3) Airgapped mobile 2FA, 4) Real-time threat detection, 5) Bug bounty programs. For institutional users, Chain-Fi can work with insurance providers to create custom coverage solutions. The platform has never experienced a security breach or loss of user funds.

Chain-Fi implements multiple anti-phishing measures: 1) QR code authentication ensures you're connecting to the legitimate Chain-Fi app, 2) Domain verification shows the official Chain-Fi domain in all communications, 3) Transaction previews in the mobile app show exactly what you're approving, 4) Address verification requires you to confirm recipient addresses, 5) Educational resources about common phishing tactics. The platform also monitors for suspicious activity and can temporarily lock accounts if phishing is detected. Users are encouraged to always verify URLs and never share their passwords or private keys.

No, Chain-Fi never has access to your private keys. Your primary wallet (MetaMask, Coinbase Wallet, etc.) manages your private keys locally on your device. Chain-Fi only receives signed transaction messages, never your private keys. The Chain-Fi address in the three-address protocol is managed by the platform, but it cannot move assets without your primary wallet signature and mobile 2FA approval. This non-custodial architecture ensures you maintain full control of your assets at all times.

Yes! Chain-Fi works with all major Web3 wallets including MetaMask, Coinbase Wallet, WalletConnect-compatible wallets, Rainbow, and Trust Wallet. You connect your existing wallet to Chain-Fi to create your unified identity. You don't need to create a new wallet. Important: When you use your bound wallet directly (outside Chain-Fi vault transactions), you pay normal gas fees. Gasless transactions only apply when interacting through Chain-Fi vault transactions with dApps that integrate Chain-Fi OAuth.

Yes, you can bind multiple wallets to a single Chain-Fi Identity. This is useful if you have different wallets for different purposes - for example, a hot wallet for daily transactions and a hardware wallet for long-term storage. All bound wallets share the same Chain-Fi Identity and KYC verification status. You can switch between wallets in your dashboard. When using Chain-Fi vault transactions with OAuth-integrated dApps, Chain-Fi handles transactions on the backend - you don't need to approve each dApp separately. If you use your bound wallets directly (not through Chain-Fi), you'll need standard wallet approvals and pay normal gas fees.

Yes, Chain-Fi fully supports hardware wallets including Ledger and Trezor. You can connect your hardware wallet through WalletConnect or directly through MetaMask. Hardware wallets provide an additional layer of security as your private keys never leave the device. The three-address protocol works seamlessly with hardware wallets - you sign transactions on your hardware device, and Chain-Fi handles the rest through the multi-signature system.

Yes! Chain-Fi offers OAuth integration for dApps and API access for Enterprise tier users. When dApps integrate Chain-Fi OAuth, users never connect their wallet directly to the dApp. Instead, users authenticate with Chain-Fi using: 1) Email/password (1FA), 2) QR code scan with Chain-Fi app (2FA) that connects to Chain-Fi or the external dApp, 3) Permission-based data exchange where users grant specific data permissions needed for dApp interaction. All transactions are protected with 2FA or 3FA. Initiating transactions through OAuth requires an additional QR code scan and wallet signature, but Chain-Fi handles everything on the backend - no additional wallet approvals to the dApp are needed. This provides benefits like: 1) One-click login with verified identity, 2) KYC status verification, 3) Permission-based data access, 4) Cross-platform authentication, 5) Enhanced security with multi-factor authentication. Enterprise tier users get full REST and WebSocket API access for custom integrations, white-label solutions, and advanced use cases. Documentation and SDKs are available for developers.

Chain-Fi is ideal for: 1) Individual crypto users who want enterprise-grade security without complexity, 2) DeFi traders who need gasless transactions across multiple chains, 3) DAOs and organizations managing treasury funds, 4) Developers building dApps who need identity and authentication solutions, 5) Businesses requiring KYC-compliant Web3 interactions, 6) Anyone who wants predictable costs instead of variable gas fees. The platform scales from individual users to enterprise organizations.

Absolutely! Chain-Fi Enterprise tier is designed for businesses, DAOs, and organizations. It includes: 1) Multi-user account management, 2) Role-based access controls, 3) API access for integrations, 4) Priority support with dedicated account management, 5) Advanced analytics and reporting, 6) Custom compliance features, 7) White-label OAuth options. Enterprise customers can also request custom integrations and dedicated support. Contact sales for enterprise pricing and custom solutions.

Yes, Chain-Fi is designed for high-value asset storage. The three-address protocol, multi-signature protection, airgapped 2FA, and audited smart contracts provide institutional-level security. Many users store significant amounts in their Chain-Fi vaults. However, for extremely high-value assets (millions+), we recommend: 1) Using hardware wallets as your primary wallet, 2) Enabling all security features, 3) Using multiple devices for 2FA, 4) Considering Enterprise tier for priority support. The platform has never experienced a security breach, making it suitable for substantial asset storage.

Yes! Chain-Fi supports DeFi operations in two ways: 1) Through Chain-Fi vault transactions - These use gasless transactions (consuming your monthly credits) and are protected with multi-factor authentication. When dApps integrate Chain-Fi OAuth, you authenticate with Chain-Fi (email/password + QR code scan) and grant permissions - you never connect your wallet directly to the dApp. Chain-Fi handles all backend transactions. 2) Direct wallet usage - You can use your bound wallet directly with any DeFi protocol, but this requires normal gas fees and standard wallet approvals. Gasless transactions only apply to vault-based interactions. Premium and Enterprise tier users can access DeFi on multiple L2 networks. The platform integrates with major DeFi protocols and DEXs. However, note that complex DeFi operations may consume multiple transaction credits depending on the number of on-chain interactions required.

Transaction speed depends on the blockchain network: Layer 2 networks (Base, Arbitrum, Optimism, Polygon) typically confirm within 1-5 seconds. Ethereum mainnet transactions confirm within 15 seconds to 2 minutes depending on network congestion. Chain-Fi's relayer network is optimized for speed and submits transactions immediately after your approval. The platform monitors network conditions and can adjust gas prices dynamically to ensure timely confirmations. Overall, Chain-Fi transactions are as fast as native blockchain transactions, with the added benefit of gasless execution.

Chain-Fi doesn't impose transaction size or value limits. You can process transactions of any size, limited only by blockchain network constraints and your available transaction credits. However, for very large transactions, the platform may require additional confirmations or security checks. Enterprise tier users can request custom limits for high-volume operations. The three-address protocol ensures security regardless of transaction size - whether you're transferring $10 or $10 million, the same security standards apply.

Yes, Chain-Fi supports all ERC-20 tokens, ERC-721 NFTs, ERC-1155 multi-tokens, and other standard token types on supported networks. You can store, transfer, and manage any compatible token in your vault. The platform also supports native tokens (ETH, MATIC, etc.) and wrapped tokens (WETH, etc.). NFT support includes viewing, transferring, and managing your NFT collections across all connected networks. All token operations use gasless transactions when you have an active subscription tier.

The Chain-Fi mobile app operates in airgapped mode and can sign transactions offline. However, the web dashboard and transaction submission require internet connectivity. Here's how it works: 1) You initiate a transaction on the web dashboard (requires internet), 2) A QR code is generated for mobile approval, 3) Your mobile app signs the transaction offline (no internet needed), 4) The signed transaction is submitted when you're back online. This airgapped architecture ensures maximum security - your mobile device never needs to be online to provide 2FA signatures.

Chain-Fi provides tiered support: Basic and Premium tiers receive email support with 24-48 hour response times and access to comprehensive documentation. Enterprise tier users get priority support with dedicated account management, faster response times (under 4 hours), phone support for critical issues, and custom integration assistance. All users have access to: 1) Knowledge base and documentation, 2) Video tutorials, 3) Community Discord server, 4) FAQ database. The platform is designed to be self-service friendly, but support is always available when needed.

Chain-Fi receives regular updates including: 1) Security patches (applied immediately for critical issues), 2) New features and improvements (monthly releases), 3) New blockchain network support (quarterly additions), 4) Mobile app updates (bi-weekly), 5) Dashboard enhancements (continuous). Users are notified of major updates via email. Mobile app updates are pushed through App Store and Google Play. The platform follows a continuous deployment model, ensuring users always have access to the latest features and security improvements.

Chain-Fi is a non-custodial platform, meaning your assets are held in smart contracts on the blockchain, not in Chain-Fi's custody. If the platform were to shut down, you would still have full access to your assets through: 1) Your primary wallet (MetaMask, etc.), 2) Direct interaction with the vault smart contracts, 3) Your mobile app for 2FA signatures. The smart contracts are immutable and will continue to function on the blockchain. However, gasless transactions and some convenience features would no longer be available. Chain-Fi is committed to long-term operation and has contingency plans for continuity.

Chain-Fi and MetaMask serve different purposes: MetaMask is a wallet for direct blockchain interactions, while Chain-Fi is a complete security ecosystem. Chain-Fi offers: 1) Subscription-based gasless transactions (MetaMask requires you to pay gas for every transaction), 2) Multi-signature vault with three-address protocol (MetaMask is a single-signature wallet), 3) Unified identity with KYC verification (MetaMask doesn't provide identity services), 4) Mobile 2FA for all operations (MetaMask relies on wallet signatures only), 5) OAuth authentication for dApps (MetaMask requires wallet connections). You can use Chain-Fi with your existing MetaMask wallet - they work together. Chain-Fi enhances MetaMask with enterprise-grade security and gasless transactions.

Chain-Fi differs from traditional multi-sig solutions (like Gnosis Safe) in several ways: 1) Subscription model with gasless transactions vs. paying gas per transaction, 2) Mobile 2FA integration (airgapped device) vs. multiple wallet approvals, 3) Unified identity and KYC verification vs. wallet-only solutions, 4) OAuth authentication for dApps vs. direct wallet connections, 5) Complete ecosystem (vault + identity + OAuth + mobile app) vs. single-purpose tools. Chain-Fi provides a comprehensive security platform rather than just a multi-sig wallet. Traditional multi-sig solutions are excellent for specific use cases, while Chain-Fi offers a broader security ecosystem with additional features.

Chain-Fi's unique approach combines: 1) Subscription-based gasless transactions (predictable costs vs. variable gas fees), 2) Three-address protocol with airgapped mobile 2FA (enhanced security vs. single or dual-signature), 3) Unified identity with KYC that works across all dApps (one verification vs. repeated KYC), 4) OAuth authentication that eliminates repeated wallet connections (better UX vs. wallet popups), 5) Complete ecosystem in one platform (vault + identity + OAuth + mobile app vs. separate tools). Unlike platforms that focus on one aspect (wallets, identity, or security), Chain-Fi provides an integrated solution that addresses multiple Web3 security and usability challenges simultaneously.

Chain-Fi's unique advantages include: 1) Predictable subscription pricing instead of variable gas fees, 2) Gasless transactions that eliminate per-transaction costs, 3) Airgapped mobile 2FA that operates offline for maximum security, 4) Unified identity that works across all dApps without repeated verification, 5) OAuth authentication that eliminates the need for repeated wallet connections, 6) Complete ecosystem (vault, identity, OAuth, mobile app) in one platform, 7) First year free access to core features after setup fee, 8) Multi-chain support with single identity, 9) Enterprise-grade security accessible to individual users, 10) Non-custodial architecture ensuring you maintain full control. These features combine to create a unique value proposition in the Web3 security space.

Chain-Fi Vault is a non-custodial, multi-signature asset protection system included in every Chain-Fi account. It uses a revolutionary three-address protocol requiring approvals from your primary wallet, Chain-Fi address, and mobile 2FA device. The vault supports ETH, ERC20 tokens, NFTs (ERC721 and ERC1155), and works seamlessly across multiple blockchain networks. It's automatically deployed when you complete the one-time setup process.

Yes! Every Chain-Fi account includes a personal vault, regardless of membership tier (Basic, Premium, or Enterprise). After completing the one-time setup process, your vault is automatically deployed, giving you immediate access to enterprise-grade asset protection. The setup fee includes your first year free, covering dashboard access, vault deposit and withdrawal capabilities, Identity verification, OAuth integrations, and the Mobile App.

The three-address protocol requires three separate addresses to approve vault transactions: 1) Your primary wallet address (from your connected wallet like MetaMask), 2) Your Chain-Fi address (managed by the platform), 3) Your mobile 2FA signature (from your airgapped Chain-Fi app). All three must approve before any asset can be moved from your vault. This means even if your computer is hacked, your phone is stolen, or the platform is compromised, your assets remain secure because an attacker would need access to all three components simultaneously.

Chain-Fi Vault supports all major digital asset types: Ethereum (ETH), ERC20 tokens (all standard tokens), ERC721 NFTs (non-fungible tokens), and ERC1155 tokens (semi-fungible tokens). You can store and manage all these assets from one unified interface across all supported blockchain networks. The vault provides the same level of security for all asset types.

Chain-Fi Vault provides enterprise-grade security through: 1) Multi-signature protection requiring three separate approvals, 2) Airgapped mobile 2FA that operates offline, 3) On-chain verification with cryptographic proofs, 4) Three-address recovery system allowing any two addresses to recover the third, 5) Guardian Attestation for ecosystem transactions providing additional verification, 6) Full auditability with complete on-chain transaction history, 7) Instant compliance and transparent actions. Even if one device is compromised, your assets remain completely secure.

Guardian Attestation provides an extra layer of verification for ecosystem transactions, ensuring instant compliance, full auditability, and transparent actions that meet regulatory standards. It's particularly important for enterprise and compliance requirements, providing verified, auditable transactions with additional oversight. All ecosystem transactions are protected by Guardian Attestation, giving users and clients immediate access to their data with instant compliance.

Chain-Fi's dual-device security model separates transaction initiation and approval across different devices. You initiate transactions on your desktop/web interface, which generates a request. This request is sent to your mobile Chain-Fi app (airgapped and offline-capable) for approval. The mobile app signs the transaction cryptographically, and only after both devices approve can the transaction execute. This separation of powers means even if your desktop is compromised, your mobile device must still approve, keeping your assets secure.

Chain-Fi Vault includes a built-in recovery option using the three-address protocol. If you lose access to one device, any two of your three addresses can recover the third after a security cooldown period. This gives you peace of mind without sacrificing security. The recovery process requires cryptographic verification and follows strict security protocols to prevent unauthorized access.

Your vault is automatically deployed when you complete the one-time setup process. After paying the setup fee (Base Chain: $8.75 or Extended Multi-Chain: $22.50 with launch discount), the platform creates and deploys your multi-signature vault smart contract on the blockchain, processes your KYC verification, and gives you immediate access. No technical expertise is required - the deployment happens automatically in the background.

Yes! If you choose the Extended Multi-Chain Setup, you can deploy vaults on all supported networks (Base, Arbitrum, Optimism, Polygon, and Ethereum mainnet). Premium and Enterprise tier users can manage multiple vaults across different chains from a single Chain-Fi dashboard. Your Chain-Fi Identity and KYC verification work across all networks, so you don't need to repeat verification for each chain.

Base Chain Setup deploys your vault on Base network only, perfect for Base-focused users. Extended Multi-Chain Setup deploys vaults on all supported networks (Base, Arbitrum, Optimism, Polygon, Ethereum mainnet), best for active multi-chain users. Both options include KYC verification and first year free access to dashboard, vault (deposit/withdraw), Identity, OAuth, and Mobile App. The Extended setup provides more flexibility for managing assets across multiple chains.

Depositing assets into your vault is simple: 1) Navigate to your vault dashboard, 2) Select the asset type (ETH, ERC20, NFT), 3) Click 'Deposit' and follow the prompts, 4) Approve the transaction with your primary wallet, 5) Confirm with your mobile 2FA app. Deposit operations don't consume transaction credits - they're included in your first year free. The assets are then secured in your multi-signature vault smart contract.

Withdrawing assets requires multi-signature approval: 1) Navigate to your vault dashboard, 2) Select the asset you want to withdraw, 3) Enter the withdrawal amount and destination address, 4) Approve with your primary wallet, 5) Confirm with your mobile 2FA app (the Chain-Fi address automatically approves). Withdrawal operations don't consume transaction credits - they're included in your first year free. All withdrawals are subject to the three-address protocol for maximum security.

Vault deposit and withdrawal operations are included in your membership and don't require transaction credits. However, these operations do incur normal blockchain gas fees. If you want gasless transactions (where Chain-Fi covers the gas fees), you can use your monthly credits included with your membership tier. Gasless transactions apply to vault-based interactions with dApps, not direct deposit/withdraw operations.

Yes! When you interact with dApps or platforms using Chain-Fi vault transactions, you can use gasless transactions with your monthly credits included in your membership tier. Gasless transactions consume credits based on your tier: Basic (10/month), Premium (50/month), or Enterprise (1,000+/month). Credit consumption varies by network: Layer 2 networks = 1 credit per transaction, Ethereum mainnet = 5 credits per transaction (Enterprise tier only). If you need additional credits, you can purchase credit packages on request (one-time purchase).

The three-address recovery system allows any two of your three addresses to recover the third if device access is lost. The three addresses are: 1) Primary wallet address, 2) Chain-Fi address, 3) Mobile 2FA address. If you lose access to one (e.g., your phone is stolen), you can use the other two to recover access after a security cooldown period. This provides peace of mind without sacrificing security - you never lose access permanently, but recovery requires multiple approvals.

The recovery cooldown period is a security feature that prevents immediate unauthorized access. When you initiate a recovery process, there's a waiting period (typically 24-48 hours) before the recovery can be completed. This gives you time to detect and prevent unauthorized recovery attempts. The exact cooldown period depends on the type of recovery and security level of your account.

Chain-Fi Vault is a core part of the Chain-Fi ecosystem and integrates seamlessly with: 1) Chain-Fi Identity - Your vault is linked to your unified Web3 identity, 2) Chain-Fi OAuth - Vault transactions can be used for dApp authentication, 3) Chain-Fi Mobile App - Required for 2FA approvals on all vault transactions, 4) Dashboard - Unified interface for managing all your assets and services. The vault works as the secure foundation for all your Web3 interactions.

Yes! When connected dApps integrate Chain-Fi, you can use your vault for transactions without connecting your wallet directly to that platform. You never connect your wallet to the dApp - the only approval is to Chain-Fi. All transactions are protected with 2FA or even 3FA (email, password, 1FA, QR code scan with Chain-Fi 2FA). Initiating transactions through OAuth requires an additional QR code scan and wallet signature. This provides better security than traditional wallet connections.

Yes! Chain-Fi Vault provides both privacy and full auditability. All transactions are recorded on-chain with cryptographic verification, ensuring complete transparency and auditability. Users and clients have immediate access to their data with instant compliance. Every action is transparent and verifiable on-chain, ensuring complete trust and regulatory compliance. You can view your complete transaction history at any time.

Chain-Fi Vault supports Ethereum mainnet, Base (Coinbase L2), Arbitrum (Optimistic Rollup), Optimism (Optimistic Rollup), and Polygon (PoS Chain). The number of networks you can use depends on your setup: Base Chain Setup (Base only), Extended Multi-Chain Setup (all networks). Premium and Enterprise tier users can deploy and manage vaults across multiple networks simultaneously from one dashboard.

Chain-Fi Identity is a unified Web3 identity system that creates a cryptographically verifiable link between your KYC-verified Chain-Fi account, your physical Chain-Fi mobile app (airgapped 2FA device), and your wallet addresses. This three-way binding ensures that vault operations require proof of ownership from both your wallet and your Chain-Fi app, providing enterprise-grade security for Web3 asset management.

Chain-Fi Identity combines four key components: 1) KYC verification through third-party providers (Sumsub, Onfido, Jumio) linked to your Chain-Fi account, 2) Vault creation using factory/clone pattern (EIP-1167) for cost-efficient deployment, 3) Wallet binding through dual signature verification (wallet signature + Chain-Fi app signature), 4) On-chain validation that records all identity linkages immutably on the blockchain. This creates a unified identity that works across all Chain-Fi products and dApps.

KYC (Know Your Customer) verification is a compliance process that verifies your identity through document checks. Chain-Fi integrates with leading KYC providers (Sumsub, Onfido, Jumio) at a cost of $1.50-$5.00 per user (average $2.50). KYC provides the foundation for enterprise-grade security and compliance, creating a trusted identity that works across all Chain-Fi products and can be used for compliant transactions, regulatory reporting, and enterprise integrations.

Chain-Fi uses the EIP-1167 minimal proxy pattern to deploy vaults efficiently. A factory contract is deployed once per blockchain network, and each user's vault is created as a minimal proxy clone pointing to the implementation contract. This dramatically reduces deployment costs (Base: ~$1.00, Multi-chain: ~$7.50 vs. $200+ for full deployments) while maintaining full security and functionality. The vault is initialized with your three-address configuration (Primary, 2FA, Secondary) and linked to your KYC-verified Chain-Fi account identity.

Wallet binding creates a cryptographically verifiable link between your wallet address and your Chain-Fi account. This process requires signatures from both your wallet (MetaMask, etc.) and your Chain-Fi mobile app, proving that you own both devices. The binding process: 1) System generates QR code with unique nonce, 2) You sign binding message with your wallet, 3) You scan QR code with Chain-Fi app which signs the message, 4) Both signatures are verified on-chain using ECDSA recovery, 5) Wallet is linked to your Chain-Fi identity in your user profile.

Wallet binding is the critical link that connects your verified Chain-Fi identity to your wallet addresses. This creates a three-way binding: your KYC-verified account, your Chain-Fi app (2FA device), and your wallet. This binding is essential for vault operations and provides enterprise-grade security by ensuring that vault operations require validated wallet binding, preventing unauthorized access. It also creates a unified identity that works across all Chain-Fi products and dApps.

On-chain validation ensures that all identity linkages are cryptographically verified and permanently recorded on the blockchain. The process includes: 1) Message construction with action type, sessionId, timestamp, nonce, and wallet address, 2) Signature recovery using ECDSA to verify both wallet and Chain-Fi app signatures, 3) Session validation to ensure active authenticated session exists, 4) Profile update storing wallet binding in user profile, 5) Vault linkage requiring validated wallet binding for all vault operations. This creates an immutable audit trail that cannot be tampered with.

Chain-Fi Identity provides enterprise-grade security through multiple layers: 1) KYC verification ensures verified identity foundation, 2) Dual signature requirement (wallet + Chain-Fi app) proves ownership of both devices, 3) On-chain validation creates immutable cryptographic proof of identity linkage, 4) Three-address protocol requires multiple approvals for vault operations, 5) Airgapped mobile app operates offline for maximum security, 6) All validations recorded on blockchain preventing tampering. This combination provides institutional-level security for Web3 asset management.

Yes! You can bind multiple wallets to your Chain-Fi Identity. Each wallet binding follows the same dual signature verification process (wallet signature + Chain-Fi app signature). You can designate one wallet as your primary address and others as fallback addresses. All bound wallets are linked to your KYC-verified Chain-Fi account identity and can be used for vault operations. This allows you to manage multiple wallets while maintaining a unified identity across all of them.

If you lose access to your Chain-Fi mobile app, you can recover access through the three-address recovery system. Any two of your three addresses (Primary wallet, Chain-Fi app address, Secondary address) can recover the third after a security cooldown period (24 hours). This ensures you never lose access to your assets while maintaining maximum security. The recovery process requires on-chain validation and follows the same security protocols as regular operations.

Chain-Fi Identity is the foundation that connects all Chain-Fi products: 1) Chain-Fi Vault uses your identity for multi-signature protection, 2) Chain-Fi OAuth uses your identity for dApp authentication, 3) Chain-Fi Mobile App uses your identity for 2FA signatures, 4) All products share the same KYC-verified account and wallet bindings. This creates a seamless, secure experience across the entire Chain-Fi ecosystem - one verified identity works everywhere.

KYC verification data is processed by third-party providers (Sumsub, Onfido, Jumio) and linked to your Chain-Fi account. The blockchain stores: 1) Cryptographic proof of identity linkage (signatures, addresses), 2) Wallet binding records, 3) Vault deployment addresses, 4) Transaction history. Personal KYC documents are not stored on-chain - only the verification status and cryptographic proofs are recorded. This provides privacy while maintaining the security benefits of on-chain validation.

The Chain-Fi Identity setup process typically takes 15-30 minutes: 1) Account creation and setup fee payment (5 minutes), 2) KYC verification (10-20 minutes depending on provider response time), 3) Vault deployment (automatic, 1-2 minutes), 4) Wallet binding (5-10 minutes including QR code scanning and signatures). The entire process is guided and can be completed in one session. KYC verification may take longer if additional documentation is required.

Yes! Chain-Fi Identity is designed for enterprise compliance: 1) KYC verification meets regulatory requirements for institutional use, 2) On-chain validation provides immutable audit trail for compliance and auditing, 3) Complete transaction history with full traceability, 4) Transparent actions that are verifiable and traceable, 5) Real-time compliance monitoring and reporting. The system meets regulatory standards for institutional use and provides the foundation for compliant Web3 operations.

The factory/clone pattern (EIP-1167) is a smart contract deployment optimization. Instead of deploying a full vault contract for each user (costing $50-$200+), a factory contract is deployed once per network, and each user's vault is created as a minimal proxy clone. This reduces deployment costs by 70-90% (Base: ~$1.00 vs. $50+, Multi-chain: ~$7.50 vs. $200+) while maintaining identical security and functionality. The pattern is industry-standard and used by major DeFi protocols for cost-efficient contract deployment.

Dual signature verification requires signatures from both your wallet and Chain-Fi app to prove ownership of both devices. The process: 1) System creates binding message with unique nonce, 2) You sign message with your wallet (proves wallet ownership), 3) You scan QR code with Chain-Fi app which signs the same message (proves app ownership), 4) Both signatures are verified on-chain using ECDSA recovery, 5) System confirms both signatures recover to correct addresses. This cryptographic proof cannot be forged - you must physically control both devices to complete the binding.

If wallet binding fails, the system will provide specific error messages: 1) Signature mismatch - signatures don't recover to expected addresses (check wallet connection and Chain-Fi app), 2) Session expired - binding session timed out (restart binding process), 3) Invalid session - session not found or not authenticated (ensure you're logged in), 4) Network error - blockchain interaction failed (retry transaction). Most issues can be resolved by restarting the binding process. Support is available if problems persist.

Yes, you can unbind wallets from your Chain-Fi Identity through the dashboard. However, unbinding a wallet that is used as a primary address for vault operations may require additional security verification. The unbinding process follows the same security protocols as binding - requiring confirmation from your Chain-Fi app. Unbinding a wallet does not affect your KYC-verified account identity or other bound wallets.

Chain-Fi Identity is unique in combining: 1) KYC verification with on-chain validation (most solutions offer one or the other), 2) Unified identity across vault, OAuth, and mobile app (most solutions are fragmented), 3) Factory/clone pattern for cost-efficient vault deployment (most solutions require expensive full deployments), 4) Dual signature wallet binding with on-chain proof (most solutions use simple wallet connections), 5) Enterprise compliance features with immutable audit trail. This creates a complete identity system rather than just wallet management.

All of this is available at no cost. The setup fee is only required when you're ready to unlock premium features like KYC verification, vault deployment, and full access to all Chain-Fi modules.

During KYC verification, Chain-Fi collects: Full legal name, Government-issued ID number, Proof of address document, Biometric data (if required by jurisdiction), and Date of birth. This information is submitted through the Chain-Fi interface and verified by third-party KYC providers (Sumsub, Onfido, or Jumio). All data is immediately encrypted before storage, and no raw PII (Personally Identifiable Information) is ever stored in plaintext.

Chain-Fi protects your KYC data through multiple security layers: 1) Immediate encryption - All PII is encrypted using AES-256-GCM encryption before storage, 2) Hashing - KYC ID is hashed with a unique salt using keccak256(sha256(kycId || uniqueSalt)), ensuring no two users have the same hash even with identical KYC IDs, 3) Off-chain storage - Encrypted PII is stored in Chain-Fi's secure off-chain database with strict access controls, 4) Audit logs - All access attempts are logged with timestamp, user ID, and purpose, 5) Compliance - Data handling is compliant with GDPR, CCPA, and other data protection regulations. No raw PII is stored on the blockchain.

After KYC verification: 1) Raw PII is encrypted with AES-256-GCM and stored off-chain in a secure database, 2) KYC ID is hashed with a unique salt and the hash is used for on-chain operations, 3) Only encrypted data is stored with role-based access control (RBAC), 4) Access is controlled with audit logs tracking all access attempts, 5) No raw PII is stored on the blockchain - only cryptographic proofs. Your encrypted data remains accessible for compliance and audit purposes, but cannot be accessed without proper authorization and is never shared with dApps or third parties.

Chain-Fi uses AES-256-GCM (Advanced Encryption Standard with 256-bit key and Galois/Counter Mode) for encrypting all personally identifiable information. This is the same encryption standard used by banks and government agencies. The KYC identifier is hashed using a two-step process: first SHA-256, then Keccak256, with a unique salt per user. The formula is: keccak256(sha256(kycId || uniqueSalt)). This ensures no two users have the same hash even with identical KYC IDs, and the hash cannot be reversed to reveal the original KYC ID.

The KYC ID hashing process uses a two-step cryptographic hash: 1) First, the KYC ID is combined with a unique salt (generated per user) and hashed using SHA-256, 2) Then, the SHA-256 result is hashed again using Keccak256 (the same hash function used by Ethereum). The formula is: keccak256(sha256(kycId || uniqueSalt)). The salt is generated per user and stored securely. This double-hashing with salt ensures: No two users have the same hash even with identical KYC IDs, the hash cannot be reversed to reveal the original KYC ID, and the process is cryptographically secure and irreversible.

Your encrypted KYC data is stored in Chain-Fi's secure off-chain database with: 1) Encrypted database with role-based access control (RBAC) ensuring only authorized personnel can access data, 2) Audit logs tracking all access attempts with timestamp, user ID, and purpose, 3) Compliance with GDPR, CCPA, and other data protection regulations, 4) Data encrypted at rest and in transit, 5) Access controlled with strict security protocols. No raw PII is stored on the blockchain - only encrypted data is stored off-chain, and only cryptographic proofs (hashes) are stored on-chain for verification purposes.

Yes, you can access your KYC verification status and related information through your Chain-Fi dashboard. However, for security and privacy reasons, raw PII (Personally Identifiable Information) is not displayed directly. You can view: 1) KYC verification status and level, 2) Verification date and expiration, 3) KYC ID hash (cryptographic proof), 4) Linked wallet addresses, 5) Vault addresses associated with your identity. If you need to update your KYC information or request data deletion, you can contact support. All data access is logged for audit purposes.

A combined hash is a cryptographic proof that links your verified identity to your wallet address. It's computed by concatenating multiple identifiers: your hashed KYC ID, user wallet address, Chain-Fi account address, vault ID, a unique nonce, and timestamp. The formula is: keccak256(kycIdHash || userAddress || chainFiAddr || vaultId || nonce || timestamp). This creates a unique, immutable link between your verified identity and wallet address. The nonce prevents replay attacks, and the timestamp ensures freshness. This combined hash is then signed by the Guardian service to create an attestation.

Guardian Attestation is a cryptographic proof that Chain-Fi has verified your KYC and attests to the linkage between your identity and wallet. The process: 1) A combined hash is computed from your KYC ID hash, wallet address, Chain-Fi address, vault ID, nonce, and timestamp, 2) The Guardian service (running on secure infrastructure) signs the combined hash using its private key stored in a Hardware Security Module (HSM), 3) The signature uses ECDSA with secp256k1 curve following EIP-191 standard, 4) The signature proves that Chain-Fi has verified your KYC and attests to the identity-wallet linkage, 5) The signature can be verified on-chain using the Guardian's public key. The private key never leaves the HSM, ensuring maximum security.

On-chain data (stored on blockchain): Combined hash (cryptographic proof linking identity to wallet), Guardian signature (ECDSA signature proving KYC verification), Timestamp (when attestation was created), Nonce (prevents replay attacks), and Vault ID (associated vault address). Off-chain data (stored in secure database): Encrypted PII (all personal information encrypted with AES-256-GCM), KYC documents (original verification documents), Access logs (audit trail of data access), and User profile data (account settings, preferences). This separation ensures: Privacy (no PII on public blockchain), Security (encrypted data in controlled environment), Auditability (on-chain proofs are immutable), and Compliance (meets data protection regulations).

Chain-Fi Identity integrates with the vault through on-chain attestation: 1) The vault smart contract verifies the attestation before allowing sensitive operations, 2) It checks that the Guardian signature is valid using the Guardian's public key, 3) It verifies that the attestation links the correct wallet to the verified identity, 4) It ensures the attestation is not expired, 5) Operations require both wallet signature and valid attestation proof. This enables: Regulatory compliance (MiCA, Travel Rule), Identity verification for DeFi protocols, KYC requirements for exchanges, and Secure operations requiring both wallet signature and valid attestation proof. The vault uses the attestation hash to verify operations, creating a secure link between your identity and vault activities.

Chain-Fi Identity attestation enables: 1) Regulatory compliance - Meets MiCA (Markets in Crypto-Assets) and Travel Rule requirements for identity verification, 2) Travel Rule compliance - Provides verified identity for cross-border transactions, 3) Identity verification for DeFi protocols - dApps can verify your KYC status without accessing your personal data, 4) KYC requirements for exchanges - Exchanges can verify your identity status through Chain-Fi attestation, 5) Enterprise integrations - Businesses can verify user identity for compliant operations, 6) Audit and reporting - Immutable on-chain records for compliance and auditing. The attestation provides proof of identity without revealing personal information, creating a privacy-preserving compliance solution.

Your KYC verification is valid for one year from the date of verification. When you finalize your Chain-Fi account, KYC verification is included in your one-time setup fee and remains valid for one year. After one year, you'll need to renew your KYC verification to maintain full access to all features. The renewal process is similar to the initial verification and may have reduced fees. Your Chain-Fi Identity, wallet bindings, and vault remain active during the renewal process. You'll receive notifications before your KYC expires to ensure continuous service.

Yes! All attestations are stored on-chain and can be viewed on blockchain explorers. When an attestation is created, you receive a transaction hash that can be viewed on: Basescan.org (for Base network), Etherscan.io (for Ethereum mainnet), or the appropriate explorer for your network. The on-chain record shows: Combined hash, Guardian signature, Timestamp, Nonce, and Vault ID. This provides complete transparency and auditability. You can also view your attestation status in your Chain-Fi dashboard, which provides a user-friendly interface to all your identity and attestation information.

Chain-Fi OAuth is a user-controlled authentication service for Web3 applications. It enables dApps to authenticate users using their Chain-Fi identity (email/password + mobile 2FA) without requiring direct wallet connections. Built on OAuth 2.0 authorization code flow with enterprise-grade security, permission-based data access, and multi-chain support across Base, Arbitrum, Optimism, Polygon, and Ethereum mainnet.

Chain-Fi OAuth follows the standard OAuth 2.0 authorization code flow: 1) User clicks "Sign in with Chain-Fi" on your dApp, 2) User authenticates with Chain-Fi (email/password = 1FA, QR code scan = 2FA), 3) User grants permission-based data access, 4) Chain-Fi redirects back with authorization code, 5) Your backend exchanges code for access token, 6) Your backend uses access token to retrieve user data. All authentication happens through Chain-Fi - users never connect wallets directly to your dApp.

Chain-Fi OAuth provides: Unified identity across all dApps (users authenticate once), Multi-factor security (email/password + mobile 2FA), Permission-based data access (users control what data is shared), KYC verification access (verify user identity without exposing personal data), Simple integration (standard OAuth 2.0 protocol), Multi-chain support (works across all supported networks), Privacy-first design (no data mining, explicit consent required), and Enterprise-grade security (CSRF protection, secure token storage, audit logging).

Integrate Chain-Fi OAuth in four steps: 1) Register your application in Chain-Fi developer dashboard to get client ID and client secret, 2) Add "Sign in with Chain-Fi" button that redirects to Chain-Fi authorization endpoint with your client ID and requested scopes, 3) Create callback endpoint that receives authorization code and exchanges it for access token using your client secret, 4) Use access token to call Chain-Fi userinfo endpoint and retrieve authorized user data. Full documentation and code examples are available in the developer portal.

Available scopes include: profile (basic user information like name and username), email (user email address), activity (user activity history and transaction records), connections (user wallet addresses and connection history), read (read-only access to user data), and write (write access for transaction operations). Users explicitly grant permissions for each scope - no data is shared without explicit consent. You can request multiple scopes, and users can approve or deny each one individually.

Yes, Chain-Fi OAuth implements enterprise-grade security: OAuth 2.0 standard protocol with authorization code flow, CSRF protection via state parameter validation, Secure token storage (access tokens are short-lived, refresh tokens stored server-side), Multi-factor authentication (email/password + mobile QR code scan), Encrypted data transmission (AES-256-GCM encryption), Complete audit logging of all authentication events, and Privacy-first design with permission-based access. All tokens are handled server-side and never exposed to frontend JavaScript.

No! That's one of the key benefits of Chain-Fi OAuth. Users authenticate with Chain-Fi using email/password (1FA) and mobile QR code scan (2FA). They never need to connect their wallet directly to your dApp. Chain-Fi handles all backend authentication and can access user wallet addresses (if user grants permission) without requiring wallet connection. For transactions, users can optionally provide wallet signature for additional security (3FA), but this is handled through Chain-Fi, not direct wallet connection to your dApp.

Chain-Fi OAuth works across all Chain-Fi-supported networks: Base (Coinbase L2), Arbitrum (Optimistic Rollup), Optimism (Optimistic Rollup), Polygon (PoS Chain), and Ethereum mainnet. One OAuth integration works for all networks. User wallet addresses are returned for all networks where the user has bound wallets. You can filter or request specific network addresses based on your dApp's needs.

To get started: 1) Create a Chain-Fi account (free account creation), 2) Navigate to developer dashboard and register your application, 3) Receive your client ID and client secret, 4) Configure your redirect URIs and requested scopes, 5) Follow the integration guide to add OAuth flow to your dApp, 6) Test in development environment, 7) Deploy to production. Full documentation, code examples, and SDK support are available. The integration typically takes 1-2 hours for experienced developers.

Traditional wallet connections require users to connect their wallet (MetaMask, WalletConnect, etc.) directly to each dApp. Chain-Fi OAuth provides: Unified identity (authenticate once, access all dApps), Multi-factor security (email/password + mobile 2FA vs. just wallet signature), Permission-based data access (users control what data is shared), KYC verification (access to user verification status), No repeated wallet connections (authenticate with Chain-Fi, not each dApp), and Better UX (familiar email/password login vs. wallet popups). Chain-Fi OAuth is designed for dApps that want secure authentication without wallet connection complexity.

Yes! Chain-Fi OAuth can be integrated alongside existing authentication systems. You can: Offer Chain-Fi OAuth as an additional login option (alongside email/password, social login, etc.), Use Chain-Fi OAuth for Web3-specific features while keeping traditional auth for other features, Migrate users gradually by offering both options, or Use Chain-Fi OAuth as primary authentication and sync user data to your existing system. The OAuth flow is independent and doesn't interfere with other authentication methods.

Chain-Fi OAuth provides refresh tokens for long-term access. When your access token expires, use the refresh token to obtain a new access token: POST to token endpoint with grant_type=refresh_token, refresh_token, client_id, and client_secret. Refresh tokens are long-lived but can be revoked by users. Store refresh tokens securely server-side (never in frontend). Implement automatic token refresh before expiration. Handle refresh token expiration by redirecting user to re-authenticate. Full token management documentation is available in the developer portal.

If a user revokes access: Your access tokens and refresh tokens are immediately invalidated, Subsequent API calls will return 401 Unauthorized, You should handle this gracefully by redirecting user to re-authenticate, User can re-authorize your dApp at any time, and All previously granted permissions are reset. Users can revoke access from their Chain-Fi account settings. It's recommended to implement token refresh error handling that detects revoked access and prompts re-authentication.

The authorization screen is managed by Chain-Fi to ensure security and consistency. However, you can customize: Application name and description (shown to users), Application logo (displayed on authorization screen), Website URL (linked from authorization screen), and Requested scopes (determines what permissions are requested). The authorization screen shows your app information, requested permissions, and allows users to approve or deny access. This ensures users always see consistent, secure authorization flows.

To test Chain-Fi OAuth: 1) Register a test application in developer dashboard, 2) Use test redirect URIs (localhost is supported for development), 3) Create test Chain-Fi accounts, 4) Test full OAuth flow (authorization → callback → token exchange → userinfo), 5) Test error scenarios (denied access, invalid codes, expired tokens), 6) Test token refresh flow, 7) Test with different scopes and permissions, 8) Use Chain-Fi's test environment for development. Full testing guide and test credentials are available in the developer documentation.

Chain-Fi OAuth API rate limits ensure fair usage: Authorization requests: 100 requests per minute per client ID, Token exchange: 60 requests per minute per client ID, Userinfo requests: 120 requests per minute per access token, Refresh token requests: 30 requests per minute per client ID. Rate limits are per client ID (not per user). Exceeding limits returns 429 Too Many Requests with Retry-After header. Enterprise tier applications can request higher rate limits. Rate limit headers are included in all API responses.

Chain-Fi OAuth is included in all Chain-Fi membership tiers. For dApp developers: OAuth integration and API access are free, No per-request fees or transaction fees, Standard rate limits apply (Enterprise tier can request higher limits), and No additional costs beyond standard Chain-Fi membership. For end users: OAuth authentication is free (part of Chain-Fi account), Users need a Chain-Fi account (free account creation), and Membership includes full access to all Chain-Fi services including OAuth. All membership tiers include monthly credits for gasless transactions.

Yes! Chain-Fi OAuth works with mobile apps using standard OAuth 2.0 flows: For native mobile apps, use custom URL schemes or universal links for redirects, For React Native/Flutter apps, use deep linking, For mobile web apps, use standard redirect flow, Chain-Fi mobile app provides 2FA via QR code scan, and All OAuth endpoints are mobile-friendly. Mobile apps should use PKCE (Proof Key for Code Exchange) for additional security. Full mobile integration guide is available in the developer documentation.

Chain-Fi OAuth is privacy-first: Permission-based access (users explicitly grant each permission), No data mining (only requested data is shared), Users can revoke access anytime, Minimal data sharing (only what's necessary for your dApp), Encrypted data transmission, No tracking or analytics on user behavior, Users see exactly what data is requested before granting access, and Complete transparency in authorization screen. Chain-Fi never shares user data without explicit consent. Users maintain full control over their data.

Chain-Fi OAuth works with any programming language that can make HTTP requests and handle OAuth 2.0 flows. Popular integrations include: JavaScript/TypeScript (Node.js, React, Vue, Angular), Python (Django, Flask, FastAPI), Go (Gin, Echo), PHP (Laravel, Symfony), Ruby (Rails), Java (Spring Boot), C# (.NET), and Rust. Chain-Fi provides: RESTful API (works with any HTTP client), SDKs for popular languages (JavaScript, Python, Go), Code examples for common frameworks, and Full API documentation. The OAuth 2.0 protocol is language-agnostic.

Yes! Chain-Fi OAuth is designed for enterprise use: Enterprise-grade security (multi-factor authentication, audit logging), Compliance support (KYC verification, data protection), Custom rate limits for Enterprise tier, Priority support and dedicated account management, White-label options (contact for details), Custom integrations and API access, SLA guarantees, and Enterprise onboarding assistance. Enterprise applications can request custom scopes, higher rate limits, and dedicated infrastructure. Contact Chain-Fi sales for enterprise pricing and custom solutions.

The Chain-Fi Mobile App is a free mobile application that provides airgapped two-factor authentication for all Chain-Fi operations. It enables secure transaction signing, OAuth authentication, and vault operation approvals through QR code scanning and biometric protection. Available for iOS and Android.

The Chain-Fi Mobile App works as an airgapped 2FA device: 1) Download and install the app, 2) Pair your device with your Chain-Fi account by scanning a QR code, 3) When you need to approve an operation, scan the QR code displayed on your screen, 4) Review transaction details in human-readable format, 5) Approve or reject using biometric authentication. All signatures are generated locally on your device.

Yes, the Chain-Fi Mobile App is completely free to download and use. There are no subscription fees, no in-app purchases, and no hidden costs. The app is available on the App Store (iOS) and Google Play Store (Android) at no charge.

The Chain-Fi Mobile App provides: Airgapped security (can operate offline), biometric protection (Face ID, Touch ID, fingerprint), encrypted storage (AES-256-GCM), private key isolation (keys never leave device), human-readable transaction display, real-time WebSocket communication, and comprehensive error handling. All sensitive operations require biometric authentication.

Yes, the Chain-Fi Mobile App is required for all wallet operations. All Chain-Fi transactions, OAuth authentications, and vault operations require mandatory 2FA via the mobile app. This ensures maximum security - no operation can be executed without your mobile device approval.

Yes! The Chain-Fi Mobile App can operate in airgapped mode. You can sign transactions offline - the app generates cryptographic signatures locally without requiring internet connectivity. When you reconnect, the signed transactions are submitted. This airgapped architecture provides maximum security.

The Chain-Fi Mobile App supports: ETH transfers and withdrawals, ERC20 token transfers and withdrawals, ERC721 NFT withdrawals, ERC1155 NFT withdrawals, account management operations, OAuth authentication requests, and vault operation approvals. All transaction types are displayed in human-readable format before signing.

To pair your device: 1) Download and install the Chain-Fi Mobile App, 2) Sign in with your Chain-Fi credentials or create a new account, 3) Open your Chain-Fi dashboard on desktop/web, 4) Navigate to device pairing section, 5) Scan the displayed QR code with your mobile app, 6) Confirm pairing on both devices. Your device is now paired and ready to provide 2FA.

Yes, you can pair multiple mobile devices with your Chain-Fi account. Each device provides independent 2FA capability. You can manage all paired devices from your dashboard, including the ability to unpair devices if you lose one or want to remove access.

If you lose your mobile device, you should immediately unpair it from your Chain-Fi account using your password and primary wallet signature from your dashboard. Then pair a new device by downloading the app and scanning the QR code. Your vault assets remain secure during this process because the three-address protocol still requires your primary wallet signature.

Yes, the Chain-Fi Mobile App generates and stores a 2FA private key locally on your device. This key is encrypted using AES-256-GCM and stored in the device's secure enclave (iOS) or hardware-backed keystore (Android). The key never leaves your device and is never transmitted to Chain-Fi servers.

Biometric authentication uses your device's built-in Face ID, Touch ID, or fingerprint scanner to unlock the Chain-Fi Mobile App. Biometric data is processed locally on your device and never transmitted to Chain-Fi. The app requires biometric authentication before displaying transaction details or generating signatures.

Biometric authentication is highly recommended for security, but you can use a PIN or password as an alternative. However, biometric authentication provides the strongest security and is required for high-value operations. The app will prompt you to enable biometrics during setup.

The Chain-Fi Mobile App supports all Chain-Fi networks: Base (Coinbase L2), Arbitrum (Optimistic Rollup), Optimism (Optimistic Rollup), Polygon (PoS Chain), and Ethereum mainnet. One app works for all networks - you can sign transactions across any supported chain.

The Chain-Fi Mobile App receives regular updates through the App Store (iOS) and Google Play Store (Android). Updates are automatic if you have auto-update enabled, or you can manually update through the respective app stores. Critical security updates are pushed immediately and may require updating before using the app.

The Chain-Fi Mobile App collects minimal information: Account credentials (email/password for sign-in), device information (for pairing and security), transaction approval data (processed locally), and app usage analytics (anonymized). Private keys, biometric data, and transaction details never leave your device.

The Chain-Fi Mobile App works alongside hardware wallets. Your primary wallet (MetaMask, Ledger, Trezor, etc.) provides one signature, and the Chain-Fi Mobile App provides the 2FA signature. The three-address protocol requires both signatures plus the Chain-Fi address for vault operations.

Transaction approval is nearly instant. The app uses WebSocket connections for real-time communication, so when you scan a QR code and approve a transaction, the approval is transmitted immediately. Total time from scan to approval is typically 2-5 seconds, depending on network conditions.

The Chain-Fi Mobile App is available globally through the App Store and Google Play Store, subject to local app store policies. Some countries may have restrictions on cryptocurrency-related apps. Check your local app store for availability.

iOS: Requires iOS 13.0 or later. Compatible with iPhone, iPad, and iPod touch. Android: Requires Android 8.0 (API level 26) or later. The app requires camera access for QR code scanning and biometric hardware (Face ID, Touch ID, or fingerprint scanner) for optimal security.

Yes! Developers can integrate Chain-Fi OAuth into their dApps, which automatically uses the Chain-Fi Mobile App for 2FA. The mobile app handles all authentication and transaction approval flows. No additional integration is needed - users simply scan QR codes with the app.

Device attestation verifies that your mobile device is genuine and hasn't been tampered with. Chain-Fi uses Google Play Integrity API (Android) and Apple App Attest (iOS) to cryptographically verify device authenticity. This ensures only legitimate, unmodified devices can access your Chain-Fi account, preventing compromised or jailbroken devices from being used.

Device attestation works by: 1) Your device generates hardware-backed attestation keys stored in secure hardware (Secure Enclave on iOS, HSM on Android), 2) The app requests an attestation token from Google/Apple APIs, 3) Chain-Fi servers verify the token using official Google/Apple verification APIs, 4) Device integrity, app authenticity, and key origin are all verified before allowing operations. This prevents spoofing and ensures maximum security.

Yes! You can configure device attestation validity periods in your Chain-Fi dashboard. Set custom validity durations (e.g., 1 day, 7 days, 30 days) based on your security requirements. Enterprise accounts can enforce maximum validity periods (e.g., 7 days) to ensure regular device re-verification for enhanced security.

Instant renewal is a security feature that requires device re-attestation before approving high-value transactions, regardless of validity period. You can configure this in your dashboard to automatically trigger re-attestation before approving vault withdrawals, large transfers, or account modifications above your configured threshold. This ensures maximum security for critical operations.

To set up instant renewal: 1) Open your Chain-Fi dashboard, 2) Navigate to device attestation settings, 3) Enable "Instant Renewal for High-Value Operations", 4) Set your transaction threshold (e.g., $10,000, 10 ETH), 5) Configure which operation types require instant renewal (vault operations, transfers, account changes). The app will automatically prompt for re-attestation when these thresholds are met.

If device attestation expires, you'll need to re-attest your device before approving operations. The app will prompt you to re-verify your device when you attempt to approve a transaction. The re-attestation process is quick - simply follow the on-screen prompts to regenerate and verify your attestation token. Your account remains secure during this process.

No, Chain-Fi Mobile App cannot be used on jailbroken (iOS) or rooted (Android) devices for security reasons. Device attestation will fail on compromised devices, preventing access to your Chain-Fi account. This protects your assets from potential security vulnerabilities that exist on modified devices.

The Chain-Fi Mobile App is chain-agnostic and project-agnostic. It works universally with any blockchain network or Web3 project. The app generates off-chain signatures that are compatible with any EVM-compatible chain (Ethereum, Base, Arbitrum, Optimism, Polygon, etc.). There are no chain limitations or project restrictions - one app for all your Web3 signing needs.

Transaction signing approves on-chain operations like ETH transfers, token transfers, and NFT operations. Authentication signing approves OAuth login requests and access permissions for dApps. The Chain-Fi Mobile App handles both types of signing - you scan QR codes and approve either transactions or authentication requests using the same device and workflow.

The 2FA signature flow works in two steps: 1) First, you scan a QR code and approve the operation on your mobile app (2FA signature), 2) Then, your primary wallet signature is required for on-chain initiation. The mobile app provides the mandatory 2FA signature, and your wallet provides the primary signature. Both signatures are required for all operations.

Yes! The Chain-Fi Mobile App is used for all OAuth login authentication. When you log into a dApp using Chain-Fi OAuth, a QR code appears on your screen. Scan it with the mobile app, review the login request and permissions, and approve or reject using biometric authentication. The app provides the 2FA signature required for OAuth authentication.

Through Chain-Fi OAuth, you can grant permissions for: Profile information (username, email), Vault access (view vault balance and operations), Identity data (KYC status, attestations), and Transaction approval (sign transactions on behalf of the platform). You can review and approve each permission individually when scanning the QR code with the mobile app.

QR code scanning is highly secure: 1) All QR codes are cryptographically signed and verified before processing, 2) QR codes contain encrypted, time-limited tokens that expire quickly, 3) Each QR code can only be used once, preventing replay attacks, 4) The app verifies QR code authenticity before displaying transaction details, 5) Invalid or tampered QR codes are immediately rejected.

The Chain-Fi Mobile App will reject any QR code that doesn't pass cryptographic verification. Malicious or tampered QR codes cannot be processed - the app verifies the signature, checks expiration, and validates the token before displaying any transaction details. If a QR code fails verification, you'll see an error message and no transaction will be displayed or signed.

Yes! The Chain-Fi Mobile App displays all transaction details in human-readable format before you sign. You'll see: Transaction type (ETH transfer, token transfer, etc.), Amount and currency, Recipient address, Network (Base, Arbitrum, etc.), Gas fees (if applicable), and Transaction purpose. Review all details carefully before approving with biometric authentication.

If you reject a transaction on the mobile app, the operation is cancelled immediately. No signature is generated, and the transaction request is terminated. The platform or dApp will receive a rejection notification. You can always initiate a new transaction request if you change your mind.

The Chain-Fi Mobile App can operate in airgapped mode - you can sign transactions offline. When you scan a QR code and approve a transaction, the signature is generated locally on your device. If you're offline, the signed transaction is stored locally and automatically submitted when you reconnect to the internet. This ensures you can always approve critical operations even without connectivity.

Yes, you can use the Chain-Fi Mobile App with multiple Chain-Fi accounts. Simply sign out and sign in with different credentials. Each account maintains its own paired devices and 2FA keys. You can switch between accounts as needed, and each account's operations are completely isolated.

The three-address protocol requires three addresses for vault operations: 1) Primary Address (your main wallet - MetaMask, Ledger, etc.), 2) 2FA Address (your Chain-Fi Mobile App device), 3) Secondary Address (recovery wallet). The mobile app provides the mandatory 2FA signature. All three signatures are required for vault operations, providing maximum security.

The Chain-Fi Mobile App protects against phishing through: 1) Cryptographic QR code verification (phishing sites can't generate valid QR codes), 2) Human-readable transaction display (you see exactly what you're approving), 3) Device attestation (prevents compromised devices), 4) Server-side verification (all operations verified on Chain-Fi servers), 5) Time-limited tokens (QR codes expire quickly). Always verify transaction details before approving.

No, the Chain-Fi Mobile App does not support key export or backup for security reasons. Keys are stored in hardware-backed secure storage and cannot be extracted. If you lose your device, you can unpair it from your dashboard and pair a new device. Your vault assets remain secure because the three-address protocol still requires your primary wallet signature.

If you uninstall the Chain-Fi Mobile App, all local data including your 2FA keys are permanently deleted from your device. You'll need to reinstall the app and pair a new device with your Chain-Fi account. Your Chain-Fi account and vault assets are unaffected - only the mobile device pairing is removed.

The Chain-Fi Mobile App ensures privacy through: 1) Local key storage (keys never leave your device), 2) Minimal data collection (only necessary account and device info), 3) Encrypted communication (all data transmitted via encrypted WebSocket), 4) No transaction history storage (transaction details are processed and discarded), 5) Biometric data never transmitted (processed locally only), 6) Anonymous analytics (usage data is anonymized).

Yes! The Chain-Fi Mobile App supports enterprise accounts with enhanced features: Configurable attestation validity periods (enforce maximum 7-day validity), instant renewal for high-value operations, operation-specific attestation policies, team device management, and audit logging. Enterprise accounts can configure stricter security policies through the dashboard.

Enterprise account administrators can manage all paired devices from the dashboard: View all paired devices, see device attestation status, configure device-specific policies, unpair devices remotely, set device attestation validity periods, and configure instant renewal thresholds. All device management actions require appropriate permissions.

Hardware-backed key attestation ensures that cryptographic keys are stored in secure hardware (Secure Enclave on iOS, Hardware Security Module on Android). The attestation proves that keys are stored in tamper-resistant hardware and cannot be extracted or modified. This provides the highest level of device binding security, ensuring keys are protected even if the device is compromised.

Server-side verification ensures all device attestation tokens are verified on Chain-Fi servers using Google and Apple's official verification APIs. This prevents attestation spoofing - even if someone tries to fake an attestation token, Chain-Fi servers will reject it because they verify directly with Google/Apple. This ensures only legitimate, verified devices can access accounts.

Yes! The Chain-Fi Mobile App is free to download and use. However, to use it for Chain-Fi operations (vault transactions, OAuth authentication), you need an active Chain-Fi account. You can create a free account and use the mobile app for basic operations, but full functionality requires a Chain-Fi subscription for vault and advanced features.

The Chain-Fi Mobile App provides 2FA signatures for Chain-Fi operations, while hardware wallets (Ledger, Trezor) provide primary wallet signatures. They work together: Your hardware wallet signs transactions as the primary address, and the mobile app provides the mandatory 2FA signature. The mobile app is specifically designed for Chain-Fi's three-address protocol, while hardware wallets are general-purpose signing devices.

The Chain-Fi Mobile App receives regular updates through the App Store and Google Play Store. Critical security patches are pushed immediately and may require updating before using the app. The app checks for updates on launch and notifies you if an update is required. Always keep the app updated to the latest version for maximum security.

Yes! The Chain-Fi Mobile App works on tablets (iPad, Android tablets) as well as phones. However, tablets must have camera access for QR code scanning and biometric hardware (Face ID, Touch ID, or fingerprint scanner) for optimal security. The app interface adapts to larger screens automatically.

If the Chain-Fi Mobile App stops working: 1) Check for app updates in the App Store/Google Play Store, 2) Restart the app, 3) Restart your device, 4) Check your internet connection, 5) Verify device attestation status in your dashboard, 6) Unpair and re-pair your device if needed, 7) Contact Chain-Fi support if issues persist. Your account remains secure during troubleshooting.

The Chain-Fi Mobile App protects against malware through: 1) Device attestation (detects compromised devices), 2) App store verification (only install from official stores), 3) Code signing (app is cryptographically signed), 4) Secure enclave storage (keys protected in hardware), 5) Runtime protection (app monitors for tampering), 6) Server-side verification (all operations verified). Never install the app from third-party sources.

Yes! You can customize mobile app settings including: Biometric authentication preferences, notification settings, app appearance (dark/light mode), transaction review preferences, and security timeout settings. Some settings like device attestation validity periods are configured in your Chain-Fi dashboard, not in the app itself.

There is no minimum transaction amount - you can approve transactions of any size with the Chain-Fi Mobile App. However, enterprise accounts can configure instant renewal requirements for high-value operations above a certain threshold. For very small transactions, standard device attestation is sufficient.

The Chain-Fi Mobile App can approve interactions with any smart contract. When you interact with a dApp or smart contract, the transaction details are displayed in human-readable format. You can approve contract calls, token approvals, NFT operations, and any other smart contract interactions. The app works with all EVM-compatible smart contracts.

Yes! The Chain-Fi Mobile App supports all DeFi operations including: Liquidity provision, yield farming, staking, lending, borrowing, swapping, and protocol interactions. When you interact with DeFi protocols, scan the QR code with the mobile app to approve transactions. All DeFi operations are displayed in human-readable format before signing.

The Chain-Fi Mobile App is specifically designed for Web3 operations: It generates cryptographic signatures (not just OTP codes), works offline in airgapped mode, supports all blockchain networks, handles both transactions and authentication, uses hardware-backed key storage, and integrates with Chain-Fi's three-address protocol. Traditional 2FA apps only provide time-based codes and don't support blockchain operations.

The Chain-Fi Mobile App ensures transaction integrity through: 1) Cryptographic signature generation (ECDSA signatures), 2) Transaction hash verification, 3) Human-readable display (you verify what you're signing), 4) Server-side validation (all signatures verified on Chain-Fi servers), 5) Replay protection (each transaction is unique), 6) Time-limited validity (signed transactions expire if not submitted).

Yes! The Chain-Fi Mobile App supports all NFT operations: ERC721 transfers and approvals, ERC1155 transfers and batch operations, NFT marketplace interactions, NFT staking, and NFT lending. When you interact with NFTs, the transaction details including collection name, token ID, and recipient are displayed in human-readable format before you approve.

The Chain-Fi Mobile App works with Chain-Fi's gasless transaction system. When you approve a transaction with the mobile app, Chain-Fi handles gas fees through your subscription. You don't need to manage gas or approve gas payments separately - the mobile app approval covers the entire transaction including gas.

The Chain-Fi Mobile App currently supports English, with plans to add more languages. The app interface, transaction displays, and error messages are all in English. Check the App Store or Google Play Store for the latest language support information.

Yes! The Chain-Fi Mobile App supports cross-chain operations. You can approve transactions on any Chain-Fi-supported network (Base, Arbitrum, Optimism, Polygon, Ethereum) using the same app. The app displays which network the transaction is for, and you approve cross-chain transfers, bridge operations, and multi-chain interactions seamlessly.

The Chain-Fi Mobile App doesn't rely on SMS or phone numbers, so it's immune to SIM swapping attacks. The app uses device attestation and hardware-backed keys that are tied to your specific device hardware, not your phone number. Even if someone swaps your SIM card, they cannot access your Chain-Fi account without your physical device and biometric authentication.

If you lose access to your mobile app: 1) Sign in to your Chain-Fi dashboard using your password and primary wallet, 2) Navigate to device management, 3) Unpair the lost device, 4) Download the app on a new device, 5) Pair the new device by scanning the QR code. Your vault assets remain secure because the three-address protocol still requires your primary wallet signature. You can also use your secondary address for recovery.

The Chain-Fi Mobile App integrates seamlessly with Chain-Fi's gasless transaction system. When you approve a transaction with the mobile app, Chain-Fi relays the transaction and pays gas fees through your subscription. You only need to approve the transaction itself - gas management is handled automatically. This makes Web3 operations as simple as traditional app approvals.

The Chain-Fi Mobile App focuses on transaction approval, not transaction history. For detailed transaction history, use your Chain-Fi dashboard. The mobile app shows transaction details only when you're approving new transactions. This design keeps the app lightweight and focused on security.

The Chain-Fi Mobile App supports batch transactions. When you approve a batch operation (multiple transactions bundled together), the app displays all transactions in the batch with their individual details. You can review each transaction before approving the entire batch. Batch transactions are common in DeFi operations and NFT marketplaces.

Chain-Fi allows you to pair multiple devices with your account for redundancy and convenience. There's no strict limit on the number of devices, but we recommend pairing 2-3 devices maximum for security and manageability. Each device provides independent 2FA capability, and you can manage all devices from your dashboard.

The Chain-Fi Mobile App ensures authenticity through: 1) App store verification (only available through official stores), 2) Code signing (app is cryptographically signed by Chain-Fi), 3) Device attestation (verifies app integrity on device), 4) Server-side verification (all app interactions verified), 5) Update verification (updates are signed and verified). Never install the app from third-party sources.

The Chain-Fi Mobile App is your complete 2FA security device that you will need for every step. It handles: 1) Login authentication (password + QR code = JWT tokens), 2) OAuth permission approvals, 3) Identity verification, 4) Vault transaction signing with airgapped security. For vault operations specifically, your mobile app provides the second signature that combines with your primary wallet signature for dual-signature on-chain validation. This creates true airgapped security where both your computer (primary wallet) and your phone (mobile 2FA) must approve before any assets can be moved. Downloading it first ensures you have all security capabilities ready before you start.

Yes! The Chain-Fi app is available on both iOS (App Store) and Android (Google Play Store). Both versions have identical security features including airgapped 2FA, QR code authentication, biometric protection, and offline transaction signing.

The Chain-Fi app is your complete 2FA security device for: 1) Login Authentication - Password (1FA) + QR code approval (2FA) generates JWT tokens for secure account access, 2) OAuth Permissions - Approve dApp connection requests and grant permission-based data access, 3) Identity Verification - Confirm your identity for KYC and cross-platform authentication, 4) Vault Transaction Approvals - Provides airgapped 2FA signature that combines with your primary wallet signature for dual-signature on-chain validation, ensuring enterprise-grade vault security. 5) Asset Management - The dual-validation system (wallet signature + mobile 2FA) provides high-end protection where both devices must approve before any vault operation executes on-chain. The app operates offline for maximum airgapped security.

When you log in or approve an action, you enter your password (1FA), then scan a QR code with the Chain-Fi app (2FA). The app generates a second JWT token that creates a binding session. For vault interactions, Chain-Fi uses dual-signature on-chain validation: your primary wallet signature (from computer) PLUS mobile 2FA approval (airgapped). The mobile app operates offline and signs transactions separately, creating true airgapped security. Both signatures are validated on-chain, ensuring that even if your computer is compromised, your vault assets remain secure. This provides enterprise-grade protection and high-end asset management capabilities.

No! The Chain-Fi app operates in airgapped mode (offline) for transaction signing and authentication. The app only needs internet to initially download and pair with your account. After pairing, all security operations including QR code generation, JWT token creation, vault transaction signing, and on-chain validation signatures work offline. This airgapped architecture ensures that even if your computer or network is compromised, your mobile device remains secure and can still provide the required 2FA signature for vault operations. The dual-signature system (primary wallet + airgapped mobile 2FA) validates on-chain for maximum security.

Chain-Fi offers three membership tiers, each a one-time purchase for 1 year membership: Basic tier - For individual users starting with Chain-Fi, includes Base chain only, 10 credits/month, KYC verification (1 year validity), and full ecosystem access. Premium tier - For users who need full multichain protection, includes all supported chains, 50 credits/month, KYC verification (1 year validity), and full ecosystem access. Enterprise tier - Custom packages for founders, teams & high-security users, includes 1,000+ credits/month, KYC/KYB verification (1 year validity), all networks including ETH mainnet, API access, and priority support. All tiers include monthly credits and full access to all Chain-Fi modules.

The one-time membership purchase is required to deploy your multi-signature vault and complete KYC verification. Account creation is free, but to access vault features and verified identity, you need to purchase a membership tier. The membership purchase includes: vault deployment, KYC verification (1 year validity), 1 year membership with monthly credits, dashboard access, vault metrics, deposit/withdraw capabilities, and full access to all Chain-Fi modules (Identity, OAuth, Mobile App) for 12 months. All membership tiers include monthly credits for gasless transactions, so no additional subscription is needed.

Your one-time membership purchase includes: vault deployment, KYC verification (1 year validity), 1 year membership with monthly credits, dashboard access, vault metrics, the ability to deposit and withdraw assets from your vault, and full access to all Chain-Fi modules (Identity, OAuth, Mobile App) for 12 months. All membership tiers include monthly credits for gasless transactions, so gasless transactions are available immediately with your membership.

Membership tiers are purchased for a 1-year period. If you need to upgrade or change your tier, you can purchase a new membership tier. Your data, identity, wallet bindings, and vault remain intact when changing tiers. If you need additional credits beyond your monthly allocation, you can purchase credit packages on request (one-time purchase) that can be used on any chain.

Gasless transactions mean the Chain-Fi platform covers all blockchain gas fees for your transactions. You receive monthly transaction credits based on your subscription tier. Credit consumption depends on the network: Layer 2 networks (Base, Arbitrum, Optimism, Polygon) = 1 credit per transaction. Ethereum mainnet (Enterprise tier) = 5 credits per transaction due to higher gas costs. Credit-based features require a monthly subscription tier, which you can add immediately to your account if you want gasless transactions right away. During your first free year, you have dashboard access, vault (deposit/withdraw), and all other modules without subscription, but gasless transactions require an active subscription tier. This provides predictable costs regardless of gas price fluctuations - you never pay per-transaction gas fees.

Membership tiers are purchased for a 1-year period. If you need to upgrade or change your tier, you can purchase a new membership tier. Your data, identity, wallet bindings, and vault remain intact when changing tiers. If you need additional credits beyond your monthly allocation, you can purchase credit packages on request (one-time purchase) that can be used on any chain.

Chain-Fi supports Ethereum mainnet, Base (Coinbase L2), Arbitrum (Optimistic Rollup), Optimism (Optimistic Rollup), and Polygon (PoS Chain). Basic tier includes Base network only. Premium tier unlocks all L2 networks (Base, Arbitrum, Optimism, Polygon). Enterprise tier includes all networks including Ethereum mainnet. More chains are added regularly based on user demand.

Wallet binding connects your Web3 wallet address to your Chain-Fi Identity. This creates a permanent link between your verified profile and your wallet, enabling: single sign-on across all Web3 apps (no repeated wallet connections), one-time KYC that works everywhere, unified identity across all dApps, automatic ownership verification, and seamless authentication. Once bound, your wallet address becomes your universal Web3 identity.

Chain-Fi supports all major Web3 wallets including MetaMask, WalletConnect (connects 300+ wallets), Coinbase Wallet, Rainbow Wallet, Trust Wallet, Ledger, Trezor, and any wallet compatible with WalletConnect v2. You can connect multiple wallets to your account and switch between them while maintaining the same Chain-Fi Identity.

Yes! You can bind multiple wallet addresses to your Chain-Fi Identity. This is useful if you have different wallets for different purposes (hot wallet for daily use, cold wallet for storage, hardware wallet for maximum security). All bound wallets share the same verified identity and KYC status.

Yes, you can unbind wallets from your Chain-Fi account at any time through your identity dashboard. However, unbinding a wallet removes its association with your verified identity. If you want to use that wallet with Chain-Fi again, you will need to re-bind it and re-verify ownership.

If you lose access to a bound wallet, you can unbind it from your Chain-Fi Identity dashboard using your other authentication methods (password + mobile app 2FA). Your Chain-Fi Identity, KYC verification, and other bound wallets remain intact. You can then bind a new wallet to your existing identity without repeating KYC.

KYC verification requires: 1) Government-issued photo ID (passport, driver license, or national ID card), 2) Selfie photo for facial verification, 3) Proof of address for Enterprise tier (utility bill, bank statement, or government document dated within 3 months). The entire process takes 5-10 minutes and verification is usually completed within 24 hours.

No! Your KYC data is encrypted and stored in your private Chain-Fi dashboard. You have complete control over what data is shared and with whom. When you connect to a dApp via Chain-Fi OAuth, you choose which permissions to grant. The dApp only receives proof that you are KYC-verified, not your actual KYC documents or personal information. This is permission-based, privacy-first data handling.

After downloading the Chain-Fi app, log into your account on desktop, go to Settings > Device Pairing, and scan the displayed QR code with your mobile app. The app generates a device-specific JWT token that creates a secure binding session. This pairs your phone to your account for 2FA approvals. You can pair multiple devices (phone, tablet) to your account.

If you get a new phone: 1) Download Chain-Fi app on new device, 2) Log into your Chain-Fi account on desktop, 3) Go to Settings and unpair old device, 4) Scan QR code to pair new device. Your account, identity, wallet bindings, and all data remain intact. You are just transferring the 2FA capability to your new device.

Complete Chain-Fi setup takes 10-15 minutes total: Step 1 - Download app (2 minutes), Step 2 - Choose membership tier and make purchase (2 minutes), Step 3 - Connect wallet (3 minutes for wallet binding), Step 4 - Complete KYC and device pairing (5-10 minutes). The membership purchase covers vault deployment, KYC processing (1 year validity), and includes 1 year membership with monthly credits. KYC verification is usually approved within 24 hours. After setup, you get dashboard access, vault (deposit/withdraw), monthly credits for gasless transactions, and all other modules (Identity, OAuth, Mobile App) for 12 months. All membership tiers include monthly credits, so gasless transactions are available immediately. You can start using basic features immediately after wallet binding while KYC is being reviewed.

No! You can complete the setup steps at your own pace. Your progress is automatically saved. However, certain features are unlocked progressively: After Step 1 (app download), you can explore the interface. After Step 2 (tier selection and setup fee payment), your vault is deployed and your first year free begins. After Step 3 (wallet binding), you can access Chain-Fi Identity and OAuth features. After Step 4 (KYC completion), you unlock full ecosystem access including vault (deposit/withdraw). Remember: The setup fee includes your first year free (dashboard, vault deposit/withdraw, and all other modules). Credit-based features (gasless transactions) require a monthly subscription tier.

Membership purchases can be paid using Stripe (credit/debit card) or Ethereum (ETH). All payment methods are secure and processed immediately. Once payment is confirmed, your vault deployment and KYC processing begin, and your 1-year membership with monthly credits starts. The membership includes: dashboard access, vault (deposit/withdraw), monthly credits for gasless transactions, and all other modules for 12 months. Note: $GUARD token payments may be available in the future if and when the token launches, but only after all product milestones are met.

Your one-time membership purchase includes: Vault deployment (multi-signature vault creation), KYC verification (identity verification processing with 1 year validity), 1 year membership with monthly credits, Dashboard access with full metrics, Vault functionality (deposit assets, withdraw to wallet, view balances), Chain-Fi Identity (KYC, wallet binding, unified identity), Chain-Fi OAuth (connect to dApps, permission management), and Chain-Fi Mobile App (2FA, device pairing, authentication). All membership tiers include monthly credits for gasless transactions, so gasless transactions are available immediately.

Your membership includes: Monthly credits for gasless transactions (platform covers gas fees), Transaction credits (monthly allocation based on tier), Cross-chain operations using credits, Advanced vault operations that consume credits, Dashboard access, Vault deposit/withdraw, Identity, OAuth, and Mobile App. All membership tiers include monthly credits, so gasless transactions are available immediately. If you need additional credits beyond your monthly allocation, you can purchase credit packages on request (one-time purchase) that can be used on any chain.

If you make a mistake during setup, you can correct it at any time. For example: 1) Wrong wallet connected - You can unbind and reconnect the correct wallet, 2) Wrong tier selected - You can upgrade or downgrade your tier, 3) KYC information error - Contact support to update your KYC information, 4) Device pairing issue - Unpair and re-pair your device. Most setup steps can be redone without additional fees. However, vault deployment and KYC processing fees are non-refundable once completed. Contact support if you need assistance correcting setup errors.

Yes, you can complete setup at your own pace. Your progress is saved automatically. However, certain features are only available after completing specific steps: After Step 1 (app download) - You can explore the interface. After Step 2 (setup fee payment) - Your vault is deployed and first year free begins. After Step 3 (wallet binding) - You can access Identity and OAuth features. After Step 4 (KYC completion) - Full ecosystem access including vault deposit/withdraw. You can use available features while completing remaining steps, but full functionality requires completing all four steps.

If your KYC verification is rejected, you'll receive an email explaining the reason. Common reasons include: 1) Poor photo quality or unclear documents, 2) Expired identification documents, 3) Mismatched information, 4) Document not accepted in your region. You can resubmit your KYC application with corrected information. There's no additional fee for resubmission. If you continue to have issues, contact support for assistance. KYC verification is processed by third-party providers, and Chain-Fi support can help troubleshoot verification problems.

KYC is required for certain features but not all. You can: 1) Create an account and explore the dashboard without KYC, 2) Download the mobile app and pair your device without KYC, 3) Connect your wallet and use Identity features without KYC. However, KYC is required for: 1) Vault deposit/withdraw operations, 2) High-value transactions, 3) Enterprise tier access, 4) Certain compliance features. You can start using Chain-Fi immediately and complete KYC when you need those features. KYC verification typically takes 5-10 minutes to submit and 24 hours for approval.

Some setup options can be changed, others cannot: Can change: 1) Membership tier (upgrade/downgrade anytime), 2) Connected wallets (add/remove wallets), 3) Paired devices (unpair/repair devices), 4) KYC information (update with support assistance). Cannot change: 1) Setup fee option (Base vs Extended) - You'd need to pay for additional network deployments, 2) Vault deployment network (without additional fees). If you chose Base setup but later want multi-chain access, you can upgrade your tier and deploy vaults on additional networks, but this may incur additional deployment costs.

The Chain-Fi mobile app is compatible with: iOS devices running iOS 13.0 or later (iPhone 6s and newer, iPad with iOS 13+), Android devices running Android 8.0 (Oreo) or later. The app requires: 1) Camera access for QR code scanning, 2) Biometric authentication (Face ID, Touch ID, or fingerprint) for security, 3) Internet connection for initial download and pairing (offline operation after pairing). The app is optimized for smartphones but also works on tablets. You can pair multiple devices to your account for redundancy.

Yes, you can pair multiple devices (phone, tablet, etc.) to your Chain-Fi account. This provides redundancy - if one device is lost or unavailable, you can use another device for 2FA approvals. All paired devices have the same level of access and can approve transactions. However, for security, we recommend: 1) Keeping paired devices secure, 2) Unpairing devices you no longer use, 3) Using devices you control (not shared devices). You can manage paired devices in your dashboard settings.

If your phone battery dies during a transaction, the transaction will not complete until you can approve it with your mobile app. Transactions require both your primary wallet signature AND mobile 2FA approval. If your phone is unavailable, you can: 1) Charge your phone and complete the approval, 2) Use another paired device if you have one, 3) Cancel the pending transaction from your dashboard. The transaction will remain pending until you provide the mobile 2FA approval. This is a security feature - transactions cannot complete without all required approvals.

No, the Chain-Fi app is designed to be battery-efficient. It operates primarily in offline mode, only connecting to the internet when necessary (like during pairing or syncing). The app uses minimal background resources and doesn't run constant processes. Battery usage is similar to other security apps. The app only activates when you: 1) Open it to approve a transaction, 2) Scan a QR code, 3) View your account status. For optimal battery life, ensure the app is updated to the latest version.

The Chain-Fi mobile app is required for 2FA security, which is a core security feature. However, if you don't have a smartphone, you can: 1) Use a tablet with the Chain-Fi app, 2) Use an iPod Touch or other iOS device with camera and internet, 3) Contact support for alternative solutions (may require Enterprise tier). The mobile app is essential for the three-address protocol security model. Without it, you cannot use vault features that require multi-signature approval. The app is free and available on both iOS and Android.

In Chain-Fi's three-address protocol: Primary wallet is your main wallet (MetaMask, Coinbase Wallet, etc.) that you use for daily operations. It provides the first signature for vault transactions. Fallback wallet is an optional backup wallet that can be used if your primary wallet is compromised or unavailable. Both wallets are bound to your Chain-Fi Identity and share the same KYC status. You can switch between primary and fallback wallets in your dashboard. Having a fallback wallet adds an extra layer of security and redundancy.

Yes, you can use different wallets for different blockchain networks. For example, you might use MetaMask for Ethereum and Base, and Coinbase Wallet for Polygon. All wallets are bound to your single Chain-Fi Identity, so you maintain one unified identity across all networks. When you interact with a specific network, Chain-Fi will use the wallet you've designated for that network. You can manage wallet-network associations in your dashboard settings. This flexibility allows you to use the wallet you prefer for each network while maintaining a single Chain-Fi account.

If your wallet provider has an outage, you can: 1) Wait for the provider to restore service, 2) Switch to a different wallet provider (if you have one bound to your account), 3) Use your fallback wallet if configured. Your Chain-Fi vault and assets remain secure during wallet provider outages because the three-address protocol requires multiple approvals. The outage only affects your ability to initiate new transactions, not the security of your existing assets. Chain-Fi recommends having multiple wallet options bound to your account for redundancy.

No, you don't need to keep your wallet constantly connected. Your wallet binding creates a permanent link between your wallet address and Chain-Fi Identity. You only need to connect your wallet when: 1) Initiating transactions that require your wallet signature, 2) Switching between bound wallets, 3) Adding new wallets to your account. For security, it's recommended to disconnect your wallet when not actively using Chain-Fi. The binding remains active, and you can reconnect anytime. This reduces the risk of unauthorized transactions if your computer is compromised.

Chain-Fi KYC verification supports most countries worldwide through our third-party verification providers. Supported regions include: United States, Canada, United Kingdom, European Union countries, Australia, New Zealand, Japan, South Korea, Singapore, and many others. Some countries may have restrictions or require additional documentation. If your country is not listed, contact support to check availability. KYC requirements vary by region - some regions may require additional proof of address or enhanced verification for Enterprise tier users.

Yes, your KYC information is stored with bank-level encryption and security. Chain-Fi uses industry-leading third-party KYC providers (similar to those used by major financial institutions) who are compliant with GDPR, CCPA, and other data protection regulations. Your KYC data is: 1) Encrypted at rest and in transit, 2) Stored in secure, compliant data centers, 3) Only accessible to authorized personnel, 4) Never shared with dApps (only verification status), 5) Subject to strict retention policies. You can request deletion of your KYC data at any time, subject to legal retention requirements.

Unfortunately, Chain-Fi requires its own KYC verification because: 1) Different services have different verification standards, 2) Chain-Fi needs to verify identity specifically for its security protocols, 3) Cross-platform KYC sharing raises privacy concerns. However, the process is quick (5-10 minutes) and you only need to do it once. Your Chain-Fi KYC verification works across all Chain-Fi services and any dApps that integrate Chain-Fi OAuth, so you won't need to verify again for each dApp connection.

Chain-Fi uses tiered KYC levels: Basic KYC (Level 1) - Required for: Account creation, wallet binding, basic Identity features, mobile app pairing. Standard KYC (Level 2) - Required for: Vault deposit/withdraw, gasless transactions, OAuth connections, Premium tier access. Enhanced KYC (Level 3) - Required for: Enterprise tier, high-value transactions, API access, custom compliance features. Most users only need Basic or Standard KYC. Enhanced KYC is only required for Enterprise tier users or specific high-value use cases. The KYC level is automatically determined based on your tier and usage.

If you can't scan the QR code, try: 1) Ensure good lighting and hold phone steady, 2) Clean your camera lens, 3) Move closer or further from the QR code, 4) Try a different device or browser, 5) Refresh the page to generate a new QR code, 6) Check that camera permissions are enabled for the Chain-Fi app. If scanning still fails, you can: 1) Use manual pairing code (if available), 2) Contact support for alternative pairing methods, 3) Try pairing from a different device. QR code scanning is the primary method, but support can provide alternatives if needed.

Yes! You can import your existing wallet into Chain-Fi through wallet binding. During setup, connect your existing wallet (MetaMask, WalletConnect, Coinbase Wallet, etc.) to bind it to your Chain-Fi Identity. Your wallet address becomes part of your unified Chain-Fi Identity, and you can use it with all Chain-Fi features including vault operations, OAuth authentication, and cross-platform access. You don't need to create a new wallet - just bind your existing one. All your existing assets remain in your wallet and can be transferred to your Chain-Fi vault if desired.

Migrating from MetaMask to Chain-Fi is simple: 1) Create a Chain-Fi account (free), 2) Download the Chain-Fi mobile app, 3) During setup, connect your MetaMask wallet through wallet binding, 4) Your MetaMask wallet becomes your primary wallet in Chain-Fi, 5) Complete KYC verification and vault setup, 6) Transfer assets from MetaMask to your Chain-Fi vault (optional). You don't need to abandon MetaMask - you can continue using it, but now it's enhanced with Chain-Fi's security features including multi-sig vault, mobile 2FA, and unified identity. Your MetaMask wallet remains fully functional.

Chain-Fi doesn't automatically import transaction history from other wallets, but you can: 1) View your transaction history on blockchain explorers (Etherscan, Basescan, etc.) using your wallet address, 2) Use Chain-Fi's dashboard to view transactions made through Chain-Fi services, 3) Export transaction data from your previous wallet and import it manually if needed. Chain-Fi focuses on future transactions and security rather than historical data migration. All new transactions made through Chain-Fi (vault operations, OAuth connections, etc.) are automatically tracked in your dashboard.

To transfer assets to your Chain-Fi vault: 1) Complete Chain-Fi setup (account creation, KYC, vault deployment), 2) From your existing wallet, send assets to your Chain-Fi vault address (found in your dashboard), 3) Confirm the transaction with your existing wallet, 4) Assets will appear in your Chain-Fi vault once the transaction is confirmed on-chain. The transfer is a standard blockchain transaction - you pay gas fees (or use Chain-Fi gasless credits if you have an active subscription). Your vault address is a multi-signature smart contract that requires your primary wallet signature + mobile 2FA for withdrawals.

Yes! Chain-Fi fully supports hardware wallets (Ledger, Trezor, etc.) through WalletConnect integration. To use your hardware wallet: 1) Connect your hardware wallet to Chain-Fi during wallet binding, 2) Your hardware wallet becomes your primary wallet in the three-address protocol, 3) All vault operations require your hardware wallet signature + mobile 2FA, 4) Your hardware wallet remains the primary security layer. This provides maximum security: hardware wallet (primary signature) + Chain-Fi mobile app (2FA signature) + optional fallback wallet. Your hardware wallet continues to work exactly as before, but now with Chain-Fi's enhanced security features.

To migrate from another multi-sig solution: 1) Create a Chain-Fi account and complete setup, 2) Deploy your new Chain-Fi vault (included in setup fee), 3) Transfer assets from your old multi-sig to your new Chain-Fi vault address, 4) Update any integrations or dApps to use your new Chain-Fi vault address, 5) Once migration is complete, you can close your old multi-sig (if desired). The migration process is straightforward - it's essentially transferring assets from one address to another. Chain-Fi's three-address protocol provides similar security to other multi-sig solutions but with additional features like mobile 2FA, unified identity, and gasless transactions.

Yes! You can transfer your NFTs to your Chain-Fi vault. NFTs are ERC-721 or ERC-1155 tokens, so they can be transferred like any other token: 1) Complete Chain-Fi setup and vault deployment, 2) From your current wallet, transfer NFTs to your Chain-Fi vault address, 3) NFTs will appear in your Chain-Fi dashboard once transferred. Your vault can hold any ERC-721 or ERC-1155 NFTs on supported networks (Base, Arbitrum, Optimism, Polygon, Ethereum). NFTs in your vault are protected by the same multi-signature security (primary wallet + mobile 2FA) as other assets. You can view and manage your NFT collection in your Chain-Fi dashboard.

During migration, your assets are transferred from your old wallet/solution to your Chain-Fi vault. The process: 1) Assets remain in your original wallet until transfer is complete, 2) You initiate transfers from your original wallet to your Chain-Fi vault address, 3) Each transfer is a standard blockchain transaction (you pay gas or use Chain-Fi credits), 4) Assets appear in your Chain-Fi vault once transactions are confirmed, 5) Your assets are protected by Chain-Fi's multi-signature security immediately upon arrival. There's no downtime - you can migrate gradually or all at once. Your assets are never at risk during migration because transfers are standard blockchain transactions with on-chain confirmation.

Account recovery depends on what you've lost: Lost password - Use password reset via email. Lost mobile device - Unpair old device and pair new device using your password and wallet signature. Lost wallet - Unbind lost wallet and bind new wallet (your Chain-Fi Identity and KYC remain intact). Lost everything - Contact support immediately. Recovery may be possible if you can verify your identity through KYC information. However, if you lose your password, wallet, AND mobile device, recovery becomes difficult. Chain-Fi recommends: 1) Writing down recovery information securely, 2) Using multiple devices, 3) Setting up fallback wallets.

You can verify transaction success through: 1) Chain-Fi dashboard - Shows transaction status and confirmations, 2) Blockchain explorer - View transaction on the native blockchain explorer (Etherscan, Basescan, etc.), 3) Mobile app - Transaction history shows approved transactions, 4) Email notifications - Receive confirmation emails for completed transactions. Successful transactions will show: "Confirmed" status, transaction hash, block number, gas used, and timestamp. Failed transactions will show error messages explaining the failure reason. All transactions are recorded on-chain and can be verified independently.

If a transaction fails or gets stuck: 1) Check transaction status in dashboard - It may still be pending, 2) Check blockchain network status - Network congestion can delay transactions, 3) Verify you have sufficient credits (for gasless transactions), 4) Check error messages for specific failure reasons. Common issues: Insufficient credits, network congestion, invalid recipient address, contract interaction failure. If transaction is stuck: 1) Wait for network confirmation (can take up to 2 hours on Ethereum mainnet), 2) Contact support with transaction hash, 3) Support can help investigate and potentially resubmit if needed. Failed transactions don't consume credits, but stuck transactions may require manual intervention.

You can cancel pending transactions that haven't been submitted to the blockchain. Once a transaction is submitted (has a transaction hash), it cannot be cancelled - it will either succeed or fail on-chain. To cancel a pending transaction: 1) Go to your dashboard transaction history, 2) Find the pending transaction, 3) Click cancel (if available), 4) Confirm cancellation. Note: If you've already approved with mobile 2FA, the transaction may be in the process of submission. Contact support if you need to cancel a transaction that's already been approved. For on-chain transactions, you'd need to submit a replacement transaction with higher gas (not applicable for gasless transactions).

Currently, Chain-Fi doesn't support fully automated transactions for security reasons (the three-address protocol requires manual approval). However, Enterprise tier users can use the API to create custom automation solutions with proper security controls. For recurring payments, you can: 1) Set up subscription billing through Chain-Fi (for Chain-Fi services), 2) Use the dashboard to quickly approve recurring transactions manually, 3) Contact Enterprise support for custom automation solutions. The platform prioritizes security over automation - all vault transactions require explicit approval to prevent unauthorized automated withdrawals.

Yes! Chain-Fi provides transaction history and reporting features: 1) Complete transaction history with filters and search, 2) Export transaction data (CSV, JSON) for accounting software, 3) Portfolio tracking across all networks, 4) Tax reporting assistance (transaction summaries). Enterprise tier users get: 1) Advanced analytics and reporting, 2) Custom report generation, 3) API access for integration with accounting systems, 4) Dedicated support for business use cases. The platform is designed to support both individual and business users with comprehensive transaction tracking and reporting capabilities.

Chain-Fi provides transaction history and export capabilities to assist with tax reporting, but does not provide tax advice or calculate taxes. You can: 1) Export all transactions (CSV, JSON format), 2) Filter transactions by date, network, type, 3) View transaction details including amounts, fees, and timestamps, 4) Generate summaries for tax preparation. The exported data includes all information needed for tax software like CoinTracker, Koinly, or manual tax preparation. Chain-Fi recommends consulting with a tax professional for tax advice. The platform maintains complete transaction records for your records.

Yes! Chain-Fi works with dApps in two ways: 1) Through Chain-Fi OAuth integration - When dApps integrate Chain-Fi OAuth, you authenticate with Chain-Fi (email/password = 1FA, QR code scan = 2FA) and grant specific data permissions. You never connect your wallet directly to the dApp - Chain-Fi handles all backend transactions. Initiating transactions requires an additional QR code scan and wallet signature, but Chain-Fi manages everything. All transactions are protected with 2FA or 3FA. Gasless transactions apply to these vault-based interactions. 2) Direct wallet usage - You can use your bound wallet directly with any dApp, but this requires normal wallet approvals and gas fees. Gasless transactions only apply to Chain-Fi vault transactions with OAuth-integrated dApps. Popular integrations include: Uniswap, Aave, Compound, Curve, and other major DeFi protocols. The platform doesn't restrict which dApps you can use - you have full freedom to interact with any protocol on supported networks.

When dApps integrate Chain-Fi OAuth, the authentication flow is: 1) User enters email/password on Chain-Fi (1FA), 2) User scans QR code with Chain-Fi mobile app (2FA) - this connects to Chain-Fi or the external dApp, 3) User grants permission-based data exchange specifying what data the dApp can access, 4) User is authenticated to the dApp without ever connecting their wallet directly. For transactions: User initiates transaction through OAuth, scans additional QR code, provides wallet signature, and Chain-Fi handles the backend execution. The user never needs to approve the dApp directly - all approvals go through Chain-Fi. This provides enhanced security with multi-factor authentication (2FA or 3FA) and eliminates the need for repeated wallet connections to each dApp.

Chain-Fi vault transactions: 1) Use gasless transactions (platform covers gas fees, consumes monthly credits), 2) Protected with multi-factor authentication (email/password + QR code + wallet signature), 3) When using OAuth-integrated dApps, you never connect wallet directly - Chain-Fi handles backend, 4) All transactions go through Chain-Fi's security protocols, 5) Available only with active subscription tier. Direct wallet usage: 1) You pay normal gas fees yourself, 2) Standard wallet approvals required for each dApp, 3) You connect your wallet directly to dApps, 4) No gasless benefits, 5) Available regardless of subscription status. Gasless transactions and enhanced security only apply to Chain-Fi vault transactions, not direct wallet usage.

Chain-Fi accepts multiple payment methods: 1) Stripe (credit/debit cards) - Available now for membership purchases and credit packages, supports major cards (Visa, Mastercard, American Express), 2) Ethereum (ETH) - Pay directly with ETH for membership purchases and credit packages. All payment methods are secure and processed immediately. Membership purchases can be paid with Stripe or ETH. Credit packages can be purchased on request using Stripe or ETH. Note: $GUARD token payments may be available in the future if and when the token launches, but only after all product milestones are met and the token provides clear utility to the Chain-Fi product.

Yes! Chain-Fi accepts Ethereum (ETH) for membership purchases and credit packages. You can pay directly from your wallet using ETH. When paying with ETH, you'll receive a payment address and can send the exact amount required. Payments are confirmed on-chain and your account is updated automatically once the transaction is confirmed. Note: You'll need to pay gas fees for ETH payments, but this is separate from your Chain-Fi membership. $GUARD token payments may be available in the future if and when the token launches, but only after all product milestones are met and the token provides clear utility to the Chain-Fi product.

However, KYC processing costs are non-refundable as they're paid to third-party verification services. Credit packages purchased on request are non-refundable once purchased. Refunds are processed within 5-10 business days to your original payment method.

When your 1-year membership expires: 1) You'll need to purchase a new membership tier to continue using Chain-Fi services, 2) Your account, vault, and all data remain intact, 3) You can purchase a new membership tier at any time to restore full access. Your vault smart contracts remain on the blockchain, but you'll need an active membership to access Chain-Fi services including dashboard, gasless transactions, and all modules.

Yes! Credit packages can be purchased on request (one-time purchase) if you need additional credits beyond your monthly allocation. Credit packages can be used on any chain - L2 networks consume 1 credit per transaction, and ETH mainnet consumes 5 credits per transaction. Credit packages are purchased separately from your membership and can be bought anytime you need additional credits.

To update your payment method: 1) Log into your dashboard, 2) Navigate to Billing > Payment Methods, 3) Click 'Add Payment Method' or 'Update Payment Method', 4) Enter your new payment details (card information for Stripe, or connect wallet for ETH), 5) Set as default payment method if desired, 6) Save changes. For Stripe: You can add multiple cards and choose which to use. For ETH: You can update the wallet address used for payments. Your payment method is securely stored and encrypted. You'll receive email confirmation when your payment method is updated.

All invoices and receipts can be downloaded as PDF for your records.

Your membership is valid for 1 year from the date of purchase. During this time, you have full access to all Chain-Fi modules, monthly credits for gasless transactions, and all features included in your tier. When your membership expires, you can purchase a new membership tier to continue using Chain-Fi services. Your account, vault, and all data remain intact.

Yes! You can purchase multiple credit packages on request (one-time purchase) as needed. Credit packages can be used on any chain and don't expire, so you can build up credits for future use. Credit packages are separate from your monthly membership credits and can be purchased anytime through your dashboard.

Chain-Fi prices are displayed in USD (US Dollars). All pricing on the website, dashboard, and invoices is shown in USD. When paying with Stripe (credit/debit cards), your card issuer will convert the USD amount to your local currency at their exchange rate. When paying with ETH, you'll pay the equivalent ETH amount based on current exchange rates. Exchange rates fluctuate, so the exact amount in your local currency may vary slightly. All transactions are processed in USD, and you'll see the USD amount on all receipts and invoices.

Chain-Fi pricing is transparent with no hidden fees. However: 1) Sales tax/VAT may apply depending on your location and local tax laws, 2) Stripe may charge processing fees for card payments (typically 2.9% + $0.30), 3) ETH payments require gas fees (paid separately, not to Chain-Fi), 4) KYC processing costs ($1.50-$5.00) are included in setup fees. All fees are clearly displayed before payment. For Enterprise tier customers, custom pricing and tax handling can be discussed with your account manager. Contact support if you have questions about taxes in your jurisdiction.

To change your email address: 1) Log into your Chain-Fi dashboard, 2) Navigate to Account Settings, 3) Click on 'Email' or 'Account Information', 4) Enter your new email address, 5) Verify the new email address by clicking the confirmation link sent to your new email, 6) Confirm the change with your password and mobile 2FA. Your email address is used for account recovery and important notifications, so make sure to use an email you have access to.

To change your password: 1) Log into your Chain-Fi dashboard, 2) Go to Account Settings > Security, 3) Click 'Change Password', 4) Enter your current password, 5) Enter your new password (must meet security requirements), 6) Confirm your new password, 7) Approve the change with your mobile 2FA.

To update your profile information: 1) Log into your Chain-Fi dashboard, 2) Navigate to Profile Settings, 3) Update any editable fields (username, display name, bio, etc.), 4) Click 'Save Changes', 5) Approve with mobile 2FA if required. Note: Some information like KYC data may require additional verification. Your wallet addresses and vault information cannot be changed from profile settings - these require separate processes.

Yes, you can change your username from your Profile Settings. However, username changes are limited to once every 30 days to prevent abuse. To change your username: 1) Go to Profile Settings, 2) Click on your current username, 3) Enter your new username (must be unique and meet requirements), 4) Save changes. Your username is used for your Chain-Fi Identity and appears in OAuth connections, so choose carefully.

To delete your Chain-Fi account: 1) Log into your dashboard, 2) Go to Account Settings > Privacy, 3) Scroll to 'Delete Account', 4) Read the deletion warning carefully, 5) Enter your password to confirm, 6) Approve with mobile 2FA, 7) Confirm deletion. Important: Account deletion is permanent and irreversible. Before deleting: 1) Withdraw all assets from your vault, 2) Unbind all wallets, 3) Cancel any active subscriptions, 4) Export any data you want to keep. Your vault smart contracts will remain on-chain, but you'll lose access to Chain-Fi services.

If you delete your Chain-Fi account, your assets remain in your vault smart contracts on the blockchain. However, you'll lose access to Chain-Fi services including: dashboard access, gasless transactions, OAuth authentication, and mobile app 2FA. To access your assets after account deletion, you would need to interact directly with the vault smart contracts using your primary wallet. We strongly recommend withdrawing all assets before deleting your account. Contact support if you need assistance with asset recovery after account deletion.

Yes, you can create multiple Chain-Fi accounts, but each account requires: 1) A unique email address, 2) A separate one-time setup fee, 3) Individual KYC verification, 4) Separate vault deployments. Each account is completely independent with its own identity, vault, and subscription. However, you cannot use the same email address or wallet address for multiple accounts. If you need multiple accounts for business purposes, consider the Enterprise tier which supports multi-user account management.

To update your KYC information: 1) Log into your dashboard, 2) Navigate to Identity Settings > KYC Verification, 3) Click 'Update KYC Information', 4) Follow the verification process (similar to initial KYC), 5) Submit updated documents, 6) Wait for verification approval (typically 24 hours). KYC updates may be required if: your documents expire, you change your legal name, you need to update your address, or you're upgrading to Enterprise tier. There may be a small fee for KYC updates depending on the changes required.

Monthly credits vary by membership tier: 1) Basic tier - 10 credits per month (Base chain only), 2) Premium tier - 50 credits per month (all L2 networks), 3) Enterprise tier - 1,000+ credits per month (all networks including ETH mainnet). Credits are consumed based on network: L2 networks = 1 credit per transaction, ETH mainnet = 5 credits per transaction. Credits reset at the start of each month. Unused credits don't roll over. You can purchase additional credit packages on request (one-time purchase) if you need more credits.

Chain-Fi doesn't impose daily transaction limits - only monthly credit allocations per tier. However: 1) Rate limiting applies to prevent abuse (typically 10-20 transactions per hour), 2) High-value transactions may require additional verification, 3) Enterprise tier customers can request custom daily limits, 4) Unusual activity patterns may trigger security reviews. Daily limits are designed to prevent abuse while allowing normal usage. If you need higher daily limits, contact support or upgrade to Enterprise tier.

Your membership tier includes monthly credits for gasless transactions. Credits are allocated monthly based on your tier: Basic tier - 10 credits/month, Premium tier - 50 credits/month, Enterprise tier - 1,000+ credits/month. Credits reset at the start of each month. Unused credits don't roll over to the next month. You can always pay your own gas for unlimited transactions beyond your credit limit. If you need additional credits, you can purchase credit packages on request (one-time purchase) that can be used on any chain.

Chain-Fi doesn't impose withdrawal limits on your vault - you can withdraw any amount from your vault at any time. However: 1) Large withdrawals may require additional 2FA verification, 2) Enterprise tier customers can configure custom withdrawal policies, 3) Regulatory requirements may apply to large withdrawals (AML reporting), 4) Network gas fees apply to all withdrawals (you pay gas or use gasless credits). Your vault assets are yours - there are no withdrawal restrictions beyond security and regulatory requirements.

No, Chain-Fi doesn't impose deposit limits - you can deposit any amount to your vault at any time. Deposits are free and unlimited. However: 1) Large deposits may trigger KYC verification requirements, 2) Regulatory reporting may apply to large deposits (AML requirements), 3) Network gas fees apply to deposits (you pay gas or use gasless credits), 4) Enterprise tier customers can configure custom deposit policies. Your vault can hold unlimited assets - there are no deposit restrictions.

Chain-Fi API rate limits vary by tier: 1) Free tier - 100 requests per hour, 2) Basic tier - 500 requests per hour, 3) Professional tier - 2000 requests per hour, 4) Enterprise tier - Custom limits (typically 10,000+ per hour). Rate limits apply per API key. Exceeding rate limits returns HTTP 429 (Too Many Requests). Rate limit headers are included in all API responses. Enterprise tier customers can request custom rate limits based on their needs.

Chain-Fi allows multiple wallet bindings per account: 1) Free tier - Up to 3 wallets, 2) Basic tier - Up to 10 wallets, 3) Professional tier - Up to 50 wallets, 4) Enterprise tier - Unlimited wallets. Each wallet binding requires verification and 2FA approval. You can unbind wallets at any time. Wallet bindings are used for OAuth authentication and vault operations. Enterprise tier customers can request custom wallet limits.

Device pairing limits vary by tier: 1) Free tier - 1 device, 2) Basic tier - 2 devices, 3) Professional tier - 5 devices, 4) Enterprise tier - Unlimited devices. Each device requires pairing via QR code and device attestation. You can unpair devices at any time from your dashboard. Enterprise tier customers can manage team devices with custom policies. Device limits ensure security while allowing flexibility for multiple devices.

Chain-Fi provides SDKs for popular programming languages: 1) JavaScript/TypeScript SDK - For Node.js, React, Vue, and other JavaScript frameworks, 2) Python SDK - For Django, Flask, and FastAPI applications, 3) Go SDK - For Go-based applications, 4) REST API - Works with any language that can make HTTP requests. All SDKs are available on GitHub and include documentation, code examples, and TypeScript definitions. The SDKs handle OAuth flows, token management, API calls, and error handling automatically.

To integrate Chain-Fi OAuth: 1) Register your application in the Chain-Fi developer dashboard to get client ID and client secret, 2) Install the Chain-Fi SDK for your language (JavaScript, Python, Go, or use REST API), 3) Add 'Sign in with Chain-Fi' button that redirects to Chain-Fi authorization endpoint, 4) Create callback endpoint that receives authorization code and exchanges it for access token, 5) Use access token to call Chain-Fi userinfo endpoint. Full integration guides, code examples, and SDK documentation are available in the developer portal. Typical integration takes 1-2 hours for experienced developers.

Chain-Fi OAuth provides refresh tokens for long-term access. When your access token expires, use the refresh token to obtain a new access token: 1) POST to token endpoint with grant_type=refresh_token, refresh_token, client_id, and client_secret, 2) Store refresh tokens securely server-side (never in frontend), 3) Implement automatic token refresh before expiration, 4) Handle refresh token expiration by redirecting user to re-authenticate. The SDKs handle token refresh automatically - you just need to handle refresh errors. Refresh tokens are long-lived but can be revoked by users from their account settings.

Chain-Fi API rate limits vary by tier: 1) Free tier - 100 requests per hour, 2) Basic tier - 500 requests per hour, 3) Professional tier - 2000 requests per hour, 4) Enterprise tier - Custom limits (typically 10,000+ per hour). Rate limits apply per API key. Exceeding limits returns HTTP 429 (Too Many Requests) with Retry-After header. Rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset) are included in all API responses. Enterprise tier customers can request custom rate limits based on their needs.

To test Chain-Fi integration: 1) Register a test application in the developer dashboard, 2) Use test redirect URIs (localhost is supported for development), 3) Create test Chain-Fi accounts, 4) Test full OAuth flow (authorization → callback → token exchange → userinfo), 5) Test error scenarios (denied access, invalid codes, expired tokens), 6) Test token refresh flow, 7) Use Chain-Fi's test environment for development. Full testing guide and test credentials are available in the developer documentation. The SDKs include test utilities and mock servers for easier testing.

Chain-Fi provides comprehensive developer resources: 1) Developer portal with full API documentation, 2) GitHub repositories with SDKs and code examples, 3) Integration guides for common frameworks (React, Next.js, Django, etc.), 4) Code examples for OAuth flows, token management, and API calls, 5) TypeScript definitions for all APIs, 6) Postman collection for API testing, 7) Developer Discord community for support. All documentation is kept up-to-date with the latest API changes. Code examples are available in multiple languages and frameworks.

$GUARD is Chain-Fi's product-first token that will only launch if it clearly strengthens the Chain-Fi product and empowers our community. We follow a product-first philosophy: real usage, revenue, and security before any token. $GUARD will only exist if it provides genuine utility that non-token mechanisms cannot deliver. No hype cycles, no high-FDV/low-float games — just transparent gates, evidence, and accountability.

Product-first means we build and ship the Chain-Fi product first, achieve real usage and sustainable revenue, and only then consider if a token adds genuine value. The default is 'not yet' until every launch gate is green and the community can verify the evidence. We don't launch tokens to fund product development — we launch products, and only consider tokens if they enhance what already works.

There is no launch date. $GUARD will only launch if and when all 10 launch gates are green: live product with audits, meaningful usage/retention, sustainable revenue model, healthy community, governance readiness, compliance approvals, proven utility, responsible economics, ethical distribution, and post-launch transparency. The default is 'not yet' until every requirement is met and verified.

$GUARD will only exist if it extends Chain-Fi product utility or community governance in ways that non-token mechanisms cannot. We evaluate each potential utility against simpler alternatives. If a non-token solution works just as well, we use that instead. $GUARD utilities must prove clear product advantage — not just token speculation or yield farming.

$GUARD follows a fundamentally different approach: 1) Product-first (product ships before token consideration), 2) Transparent gates (10 launch requirements must all be green), 3) Utility validation (must prove better than non-token alternatives), 4) Community verification (evidence published for community review), 5) No hype cycles (no marketing before product milestones), 6) Sustainable economics (low-FDV, sufficient float, no dependency on price), 7) Radical transparency (public dashboards, unlock calendars, treasury policies). Most tokens launch to fund development — $GUARD only launches if it enhances an already-working product.

There are 10 launch gates that must all be green: 1) Live product & independent security audits (99.5% uptime, 2+ audits, no P0/P1 issues), 2) Meaningful usage & retention (≥5,000 WAU or ≥500 DAU for 8 weeks OR ≥$25k MRR), 3) Sustainable revenue model (clear pricing, margins, CAC/LTV, 6-12 month runway independent of token), 4) Healthy, verified community (≥10k verified members, 5%+ weekly active, ≥50 recurring contributors), 5) Governance charter & progressive decentralization plan (published, working groups defined, Snapshot live), 6) Compliance & risk approvals (jurisdictional analysis, KYC/AML policy, public risk factors), 7) Proven $GUARD utility (clear product advantage, 2+ utilities require $GUARD, no-token alternative analysis), 8) Responsible economics (draft supply/emissions vetted, sustainable flows, no price dependency), 9) Ethical distribution & liquidity (long-term contribution alignment, ≥20-30% initial float, 4-6 year unlocks), 10) Post-launch transparency & operations (incident response, monthly reports, kill-switch policy). If any gate is red or ambiguous, we pause.

Each launch gate has a functional lead responsible for collecting evidence and publishing it: Gate 0 (Problem & Fit) - Product, Gate 1 (Product Readiness) - Engineering, Gate 2 (Real Usage) - Product/Analytics, Gate 3 (Sustainable Economics) - Finance/RevOps, Gate 4 (Community Health) - Community, Gate 5 (Governance Readiness) - Governance, Gate 6 (Compliance & Risk) - Legal/Risk, Gate 7 (Token Utility Validation) - Product/Economics, Gate 8 (Economic Guardrails) - Tokenomics, Gate 9 (Distribution & Liquidity) - Treasury/Markets, Gate 10 (Launch & Post-Launch) - PMO. Each owner must provide verifiable evidence before their gate is marked green.

If any launch gate turns red or becomes ambiguous after being green, we pause the launch process immediately. The default is 'not to launch' — gates must remain green continuously. If conditions deteriorate (usage drops, revenue model fails, security issues, compliance problems), we halt the launch until the gate is green again. This kill-switch policy ensures we only launch when all conditions are met and maintained.

Yes! All launch gate evidence is published on the $GUARD token page with public dashboards, metrics, audit reports, and verification links. The community can review: usage metrics (WAU/DAU/MRR), security audit reports, community health metrics, governance proposals, compliance memos, utility analyses, economic models, distribution plans, and transparency reports. Nothing is hidden — all evidence is verifiable and publicly accessible.

Four non-negotiable principles govern $GUARD: 1) Utility > Hype — $GUARD must deliver product capabilities or governance superpowers that non-token mechanics cannot, 2) Community Value First — real users, contributors, and partners benefit post-product (no pre-product extraction), 3) Sustainability & Compliance — economics, treasury, and governance designed for resilient operations and jurisdictional readiness, 4) Radical Transparency — public supply dashboards, unlock calendars, treasury policies, and incident runbooks required. These principles are non-negotiable and cannot be compromised.

'Utility > Hype' means $GUARD must provide genuine functional value that cannot be achieved without a token. We reject token launches based on marketing, speculation, or 'community building' alone. Every proposed $GUARD utility must pass a 'no-token alternative' test: if a simpler non-token mechanism works just as well, we use that instead. $GUARD utilities must prove clear product or governance advantage through prototypes, simulations, and real-world testing.

'Community Value First' means real users, contributors, and partners benefit after the product is working, not before. We reject pre-product token extraction where tokens launch to fund development and early investors/speculators profit while the product remains unfinished. With $GUARD, the product ships first, achieves real usage and revenue, and only then do we consider token distribution — prioritizing long-term contributors and real usage over speculation.

'Radical Transparency' means all $GUARD information is publicly accessible: supply dashboards showing total supply, circulating supply, and unlock schedules; treasury policies showing how funds are managed and spent; unlock calendars showing exactly when and how much $GUARD unlocks; economic models showing sustainable flows across bull/bear scenarios; incident runbooks showing how we handle problems; monthly transparency reports showing usage, finances (non-sensitive), security updates, and community highlights. Nothing is hidden — everything is verifiable.

$GUARD utilities are still being validated, but potential product utilities include: network access & resource credits that map to real costs, in-app staking as signal (not yield farming), fee rebates or bonding curves tied to verifiable usage, deposits that reserve scarce resources or prevent spam, module marketplace fees that fund maintenance. Potential community & governance utilities include: voting & delegation with anti-whale protections, working-group budgets with clawbacks for non-delivery, retroactive rewards for measurable contributions, progressive decentralization milestones driven by data. All utilities must prove clear Chain-Fi product advantage before implementation.

We validate $GUARD utility through: 1) Prototype development — build working prototypes of proposed utilities, 2) Simulation modeling — run economic simulations across bull/bear scenarios, 3) No-token alternative analysis — compare $GUARD utility against simpler non-token mechanisms, 4) User testing — test utilities with real users and measure outcomes, 5) Community review — publish utility proposals for community feedback, 6) Evidence collection — gather data proving utility provides clear product advantage. Only utilities that pass all validation steps will be implemented. We publish all validation results publicly.

If $GUARD staking exists, it will be for reputation, access, or resource reservations — never for yield farming without productive backing. We reject 'stake for yield' mechanics that rely on token price appreciation or perpetual growth narratives. Any staking mechanism must serve a functional purpose (e.g., signaling commitment, reserving resources, gating access) and must be sustainable without depending on $GUARD price performance.

$GUARD token payments may be available in the future if and when the token launches, but only after all product milestones are met and the token provides clear utility to the Chain-Fi product. Currently, Chain-Fi accepts Stripe (credit/debit cards) and Ethereum (ETH) for payments. We don't assume $GUARD revenue in our base operating plan — the product must be sustainable without token payments.

$GUARD tokenomics follow responsible economics principles: total supply capped or bounded inflation with purpose, target emissions runway of 6-8 years (no front-loaded giveaways), initial circulating supply ≥20-30% (avoid high-FDV/low-float), smooth predictable unlocks (frequent small unlocks, public calendar, no mega-unlocks), distribution aligned with long-term contribution (50-65% community/users/contributors, 10-15% team with 4-year vest, 15-20% investors with 3-4 year vest, 5-10% liquidity/market ops), no reliance on $GUARD price appreciation in core value proposition. All tokenomics are published transparently before launch.

'Low-FDV, sufficient float' means: 1) Initial circulating supply ≥20-30% of total supply (avoiding high fully-diluted valuation with tiny float), 2) Realistic unlock schedules (4-6 year unlocks, no cliff-day overhangs), 3) Insider selling policies (cooling-off periods, pre-announced windows, executives on delayed schedules), 4) No artificial scarcity games. This prevents the common crypto problem where tokens launch with high valuations but tiny float, leading to price manipulation and insider dumps. $GUARD prioritizes fair distribution and sustainable economics over hype-driven valuations.

If any $GUARD distribution happens, it will prioritize long-term contributors and real usage — details will be published transparently. We reject airdrops that reward speculation, sybil attacks, or short-term engagement. Any distribution will be based on: measurable contributions (code, docs, support, ecosystem modules), real product usage (verified usage patterns, not just sign-ups), community participation (quality contributions, not just activity), long-term commitment (sustained engagement over time). Distribution plans will be published well in advance for community review.

$GUARD distribution will align with long-term contribution: 50-65% to community, users, contributors, and ecosystem (mix of treasury, grants, retro rewards), 10-15% to team including future hires (≥4-year vest with 1-year cliff, linear monthly thereafter), 15-20% to investors/partners (≥3-4 year vest, aligned with milestones), 5-10% to liquidity/market ops/reserves (strict transparency). Distribution prioritizes contributors and users over investors and insiders. All distribution plans are published transparently before launch.

$GUARD unlock schedule follows responsible economics: initial circulating supply ≥20-30%, smooth predictable unlocks (frequent small unlocks, not mega-unlocks), public unlock calendar (exact dates and amounts published), 4-6 year unlock period (no cliff-day overhangs), insider selling policies (cooling-off periods, pre-announced windows). The unlock schedule is published before launch and updated monthly. No surprises, no hidden unlocks, no insider advantages.

$GUARD governance follows progressive decentralization: Phase A (pre-$GUARD) — off-chain signaling (Snapshot), contributor program, small budgets controlled by core team. Phase B (early $GUARD) — $GUARD voting with safeguards (delegation, reputation overlays, quorum/slashing for spam, circuit breakers). Phase C (mature) — independent foundation or council with clear mandates, budget caps, audits, annual elections. Governance powers scale with product maturity and contributor readiness. Governance charter and progressive decentralization plan are published before launch.

Progressive decentralization means governance powers increase gradually as the product matures and the community demonstrates readiness. We don't launch with full decentralization immediately — that often leads to governance attacks, spam, or poor decisions. Instead, we start with off-chain signaling and small budgets, then gradually increase on-chain governance powers as the community proves capable. This protects the product while building toward true decentralization over time.

Eventually, yes — but governance powers scale with product maturity. Initially, $GUARD governance focuses on token-related decisions (distribution, utility proposals, treasury management). Product decisions remain with the core team until the community demonstrates governance readiness. Over time, governance powers expand to include product direction, feature prioritization, and strategic decisions. The progressive decentralization plan outlines exactly how and when governance powers transfer to the community.

Compliance is a launch gate requirement. Before $GUARD launches, we complete: jurisdictional analysis (decision memo on token classification and distribution constraints), KYC/AML policy (defined for any claim/airdrop if applicable), public risk factors (market, technical, regulatory risks documented), legal counsel review (independent legal counsel prior to any token issuance). We design with jurisdictional and regulatory considerations from day one. Compliance requirements vary by jurisdiction — we publish our compliance approach transparently.

Public risk factors are documented before launch, including: market risks (volatility, liquidity, regulatory changes), technical risks (smart contract vulnerabilities, network issues, key management), regulatory risks (jurisdictional changes, classification changes, enforcement actions), operational risks (team changes, infrastructure failures, security breaches), economic risks (tokenomics failures, unsustainable emissions, price dependency). All risks are published transparently — nothing is hidden. We maintain kill-switch policies to pause or cancel launch if risks become unacceptable.

Token classification is determined through jurisdictional analysis with legal counsel. We design $GUARD to provide genuine utility (product access, governance, resource reservations) rather than investment returns. However, token classification varies by jurisdiction and can change over time. We publish our legal analysis and classification decision transparently. If $GUARD is classified as a security in any jurisdiction, we comply with applicable regulations or restrict distribution in that jurisdiction.

$GUARD follows radical transparency: public supply dashboards (real-time supply, float, unlocks), unlock calendars (exact dates and amounts), treasury policies (how funds are managed, spent, and diversified), monthly transparency reports (usage metrics, finances non-sensitive, security updates, community highlights), on-chain dashboards (all $GUARD flows, grants, distributions), incident runbooks (how we handle problems), economic models (sustainable flows, simulations). Nothing is hidden — everything is verifiable and publicly accessible from day one.

Launch gate progress is tracked on the $GUARD token page with: gate status indicators (green/yellow/red), evidence links (audit reports, metrics dashboards, compliance memos), owner information (who owns each gate), verification links (how to verify evidence), community review sections (where community can comment). All gate evidence is published publicly — you can verify each requirement yourself. Gate status updates monthly or when significant changes occur.

You can hold us accountable by: reviewing launch gate evidence (verify each requirement yourself), tracking transparency reports (monthly updates on progress), participating in community discussions (provide feedback on proposals), monitoring public dashboards (supply, unlocks, treasury), reporting issues (if you find problems, report them), voting in governance (when governance is live). We publish all evidence publicly — if we can't prove a gate is green, it's not green. The community can verify everything.

You can contribute by: shipping product features (code contributions, bug fixes, improvements), writing documentation (guides, tutorials, API docs), providing support (help users, answer questions, moderate community), building ecosystem modules (integrations, tools, extensions), participating in governance (proposals, discussions, voting when live), contributing to security (bug reports, audits, security research). Contributions are tracked on public leaderboards. Long-term contributors and real usage are prioritized for any future $GUARD distribution.

Contribution is not required, but it's the primary way to potentially earn $GUARD if and when distribution happens. We prioritize long-term contributors and real usage over speculation or airdrop farming. However, $GUARD may also be available through: product usage (if $GUARD utilities require holding/spending), governance participation (if voting requires $GUARD), marketplace activities (if module marketplace uses $GUARD). Distribution plans will be published transparently before launch — nothing is guaranteed, but contribution is the most reliable path.

Contributions are tracked on public leaderboards showing: code contributions (GitHub commits, PRs, issues), documentation contributions (docs written, tutorials created), support contributions (questions answered, issues resolved), ecosystem contributions (modules built, integrations created), community contributions (discussions, proposals, moderation), security contributions (bug reports, audits, research). Leaderboards are public and verifiable — you can see exactly who contributed what and when. Long-term sustained contributions are weighted more than one-time contributions.

$GUARD differs fundamentally: 1) Product-first (product ships before token, not token to fund product), 2) Transparent gates (10 requirements must all be green, publicly verifiable), 3) Utility validation (must prove better than non-token alternatives), 4) Sustainable economics (low-FDV, sufficient float, no price dependency), 5) Radical transparency (public dashboards, unlock calendars, treasury policies), 6) Community verification (evidence published for review), 7) Kill-switch policy (can cancel launch if conditions deteriorate). Most tokens launch to fund development or reward early investors — $GUARD only launches if it enhances an already-working product.

We evaluate every proposed $GUARD utility against existing alternatives (ETH, stablecoins, existing governance tokens). If existing tokens work just as well, we use those instead. $GUARD only makes sense if it provides unique utility that existing tokens cannot: Chain-Fi-specific product access, Chain-Fi governance, Chain-Fi resource reservations, Chain-Fi ecosystem rewards. We publish 'no-token alternative' analyses showing why $GUARD is needed vs. simpler mechanisms. If we can't prove $GUARD is better, we don't launch it.

That's perfectly acceptable — and responsible. The default is 'not to launch' until all gates are green. If utilities are weak, conditions deteriorate, or we can't prove $GUARD adds value, we won't launch it. The product works without $GUARD — we don't need a token to operate. If $GUARD never launches, Chain-Fi continues operating normally with Stripe and ETH payments. A token is optional, not required. We're committed to doing the right thing, even if that means not launching a token.

Blockchain selection is part of the launch gate requirements (Gate 9: Distribution & Liquidity). We'll evaluate: Ethereum mainnet (maximum security, highest costs), Layer 2 solutions (Base, Arbitrum, Optimism, Polygon — lower costs, good security), alternative chains (if they provide better economics or features). Selection criteria include: security, decentralization, costs, ecosystem compatibility, regulatory considerations. The chosen blockchain(s) will be announced well in advance with justification for the decision.

Token standard selection depends on the chosen blockchain and required features. If launching on Ethereum or EVM-compatible chains, ERC-20 is likely. However, we'll evaluate: ERC-20 (standard fungible token), ERC-1400 (security token standard if needed), custom standards (if unique features required), multi-chain deployment (if launching on multiple chains). Token standard selection is part of Gate 8 (Economic Guardrails) and will be published with technical specifications before launch.

$GUARD integration depends on validated utilities. Potential integrations include: Vault operations (if $GUARD required for advanced features), Identity system (if $GUARD used for attestation or verification), OAuth authentication (if $GUARD used for access control), Mobile app (if $GUARD used for 2FA or device binding), Dashboard (if $GUARD used for governance or rewards). All integrations are validated through prototypes and user testing before implementation. Integration plans are published transparently.

The roadmap has three phases: Today — Ship Chain-Fi product, grow verified usage, publish monthly transparency reports. Next — Prototype $GUARD utilities, run simulations, publish 'no-token' alternative analyses, validate utilities with real users. Later — If all gates are green, publish detailed $GUARD launch plan well in advance (timeline, distribution, utilities, economics, governance). There is no fixed timeline — we move to the next phase only when current phase milestones are met. The roadmap is updated monthly in transparency reports.

There is no timeline. $GUARD launches only when all 10 gates are green and the community can verify the evidence. This could be months, years, or never — it depends on product success, community growth, utility validation, and compliance readiness. We don't set artificial deadlines or rush to launch. Quality and sustainability matter more than speed. We publish monthly updates on gate progress, but we won't launch until everything is ready.

Post-launch operations include: monthly transparency reports (usage, finances, security, community), on-chain dashboards (supply, unlocks, treasury, grants), governance activation (progressive decentralization begins), utility rollout (validated utilities go live), community programs (contributor rewards, governance participation), incident response (handling problems, security issues, market events), continuous validation (ensuring utilities remain valuable, economics remain sustainable). Post-launch operations are defined in Gate 10 and executed transparently.
