Frequently Asked Questions

Chain-Fi is a revolutionary blockchain security platform founded in February 2024 to address the $7.6+ billion in DeFi losses and security vulnerabilities. We provide institutional-grade asset protection through our innovative Three-Address Protocol combined with ChainGuard 2FA technology.

Unlike speculative crypto projects, Chain-Fi focuses on solving real security problems that have historically cost users billions in asset losses. Our platform enables both individual users and enterprises to safely participate in DeFi with enterprise-grade protection.

Chain-Fi's Three-Address Protocol eliminates the single point of failure found in traditional wallets by distributing security across three distinct addresses:

• Primary Address: Your main EOA (wallet) that initiates all transactions
• Auth Address: Connected to ChainGuard 2FA for transaction approval via mobile device
• Fallback Address: Provides emergency recovery capabilities if other addresses are compromised

Every transaction requires both initiation from your Primary Address AND approval from your Auth Address through the ChainGuard app, creating an impenetrable dual-device security model.

ChainGuard 2FA is our decentralized two-factor authentication technology that provides hardware-level security validation for your transactions. Unlike traditional 2FA systems that rely on centralized servers, ChainGuard operates through cryptographic signatures and server attestation.

When you initiate a transaction, ChainGuard generates a signature on your mobile device that must be verified on-chain before the transaction can execute. This creates a dual-device security model where attackers would need to compromise both your computer AND your mobile device to access your assets.

The system includes trusted device protocols and advanced attestation mechanisms to ensure your mobile device hasn't been compromised.

Chain-Fi provides multi-chain native support across major blockchain networks:

• Ethereum: Primary network for core protocol operations
• Base: Optimized for fast, low-cost transactions and primary trading hub
• Arbitrum: High-throughput Layer 2 scaling with optimistic rollups
• Optimism: Enhanced performance through optimistic rollup technology

Our architecture deploys native CFI tokens on each network, eliminating the need for bridges and their associated security risks. You can use Chain-Fi's security features on any supported network with the same level of protection.

Creating a Chain-Fi vault is a guided process that implements our Three-Address Protocol:

1. Connect Your Wallet: Connect your primary EOA wallet (MetaMask, Coinbase Wallet, etc.)
2. Install ChainGuard: Download our mobile app for 2FA authentication
3. Set Up Addresses: Configure your auth and fallback addresses through our secure setup process
4. Deploy Vault: Your personal vault smart contract is deployed with your Three-Address configuration
5. Transfer Assets: Move your digital assets into the vault for maximum protection

The entire process is designed to be user-friendly while implementing institutional-grade security measures behind the scenes.

Chain-Fi vaults support comprehensive digital asset protection:

• Native Tokens: ETH, MATIC, AVAX, and other native blockchain currencies
• ERC-20 Tokens: All standard fungible tokens including USDC, USDT, LINK, etc.
• NFTs (ERC-721): Individual non-fungible tokens and collectibles
• Multi-Token NFTs (ERC-1155): Gaming assets and multi-edition collectibles
• CFI Tokens: Native Chain-Fi tokens with enhanced utility features

Our smart contracts are formally verified to ensure the highest level of security for all supported asset types across all blockchain networks.

Chain-Fi's Recovery Protection System ensures you never lose access to your assets:

• Two-of-Three Recovery: Any two of your three addresses can recover the third after a security cooldown period
• Emergency Recovery Mode: Activates when normal access is compromised
• 24-Hour Security Cooldown: Prevents attackers from exploiting recovery mechanisms
• Fallback Address Control: Your designated recovery address can regain vault control

This system allows recovery even if you lose your phone or primary device while maintaining strong security against sophisticated attacks. The cooldown period ensures that recovery attempts cannot be exploited by attackers who might have gained temporary access.

Chain-Fi was specifically designed to address the $7.6+ billion in DeFi losses through comprehensive security measures:

• Eliminates Private Key Risks: Multi-address architecture prevents single point of failure attacks
• Prevents Bridge Exploits: Native multi-chain deployment eliminates bridge dependencies
• Stops Phishing Attacks: ChainGuard 2FA requires device-based approval for all transactions
• Blocks Smart Contract Exploits: Formally verified contracts with comprehensive security audits
• Prevents Social Engineering: Multi-device validation makes social engineering attacks ineffective

Our platform addresses all major vulnerability categories identified in DeFi security research, providing institutional-grade protection for individual users.

The Guardian Network is Chain-Fi's advanced validation layer that provides additional security supervision and cross-chain coordination:

• Cross-Chain Supervision: Validates complex operations across multiple blockchain networks
• Enterprise Compliance: Additional validation layer for institutional requirements
• Native Token Circulation: Manages CFI token supply across all supported chains
• Bridge-Free Swaps: Enables secure cross-chain asset transfers without traditional bridges
• Consensus Validation: Byzantine fault-tolerant consensus for critical operations

The Guardian Network will be gradually decentralized through community governance, starting with testnet operations in 2026-2027.

CFI (Chain-Fi Token) is a utility token that powers the entire Chain-Fi ecosystem:

• Membership Access: Monthly subscriptions for platform access with tiered benefits
• Platform Operations: Transaction fees, vault creation, and emergency recovery
• Ecosystem Payments: Universal payment across connected dApps and protocols
• Governance Participation: Voting on protocol parameters and security thresholds
• API Access: Payment for API calls and developer integrations

CFI tokens are natively deployed on all supported chains with a deflationary mechanism that burns tokens through platform usage, creating sustainable value capture.

Yes, Chain-Fi is specifically designed with enterprise-grade features and regulatory compliance:

• Institutional Access Control: Role-based access management and multi-signature workflows
• Regulatory Compliance: Built-in KYC/AML integration and audit trails
• Enterprise Security: Additional Guardian Network validation for institutional requirements
• Compliance Automation: GDPR, MiCA, and FATF standard alignment
• White-Label Solutions: Customizable implementations for enterprise clients

Our dual-path architecture provides both decentralized access for individuals and centralized-hybrid access for enterprises requiring additional compliance features.

Chain-Fi implements a gasless architecture with quota-based membership tiers:

• Gas Abstraction: All blockchain transaction costs absorbed by the platform
• Membership Quotas: Monthly limits on transactions, API calls, and storage based on tier
• Quota Extensions: Additional resources available via CFI tokens or fiat payment
• Enterprise PPC Model: Per-customer pricing for business accounts
• Deflationary Mechanism: Platform fees burned to reduce token supply

This model eliminates the complexity of gas fees while providing transparent, predictable costs for both individual and enterprise users.

Chain-Fi is fundamentally different from existing security solutions:

• Comprehensive Protection: Addresses all major DeFi vulnerability categories in one platform

Unlike point solutions that address individual vulnerabilities, Chain-Fi provides end-to-end security for the complete DeFi user journey.

Withdrawing assets from your Chain-Fi vault follows the same secure dual-device approval process:

1. Initiate Withdrawal: Use your Primary Address to initiate the withdrawal through our web dashboard
2. Specify Details: Choose asset type, amount, and destination address
3. ChainGuard Approval: Approve the transaction using your mobile ChainGuard app
4. Transaction Execution: Once approved, the withdrawal executes automatically

All withdrawals include comprehensive transaction previews and risk assessments to ensure you understand exactly what you're authorizing before approval.

Chain-Fi takes a proactive approach to regulatory compliance from inception:

• Compliance-First Design: Built with regulatory requirements integrated into core architecture
• Global Standards: Alignment with UK FSMA, EU MiCA, FATF, and other international frameworks
• KYC/AML Integration: Built-in identity verification and transaction monitoring
• Audit Trail Automation: Comprehensive logging for regulatory reporting
• Adaptive Framework: Architecture designed to adapt to evolving regulatory requirements

Our Compliance Director was one of our earliest team members, ensuring regulatory considerations are embedded in every platform feature and decision.

Chain-Fi implements a hybrid model that balances decentralization with practical security needs:

• Decentralized Core: Smart contracts and vault security operate without central control
• Server-Side Attestation: Device validation and threat detection for enhanced security
• Progressive Decentralization: Gradual transition to full community governance
• User Sovereignty: Users maintain complete control over their assets at all times
• No Custody: Chain-Fi never holds or controls user funds

This approach provides the security benefits of centralized validation while preserving the core principles of user ownership and asset control.
