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

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

ChainGuard 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. ChainGuard 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.
GeneralView General Page
Gasless transactions only apply when you interact with dApps or platforms using ChainGuard vault transactions. With ChainGuard, 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 ChainGuard 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.
GeneralView General Page
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 ChainGuard vault transactions. If you use your bound wallet directly (not through ChainGuard vault), you pay normal gas fees regardless of your subscription tier.
GeneralView General Page
ChainGuard uses a relayer network and meta-transaction architecture. When you initiate a transaction, it's signed by your wallet but submitted to ChainGuard'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.
