What is ChainGuard Vault?

ChainGuard Vault is a non-custodial, multi-signature asset protection system included in every ChainGuard account. It uses a revolutionary three-address protocol requiring approvals from your primary wallet, ChainGuard 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.

How does the three-address protocol work?

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 ChainGuard address (managed by the platform), 3) Your mobile 2FA signature (from your airgapped ChainGuard 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.

What assets can I store in my ChainGuard Vault?

ChainGuard 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.

How secure is the ChainGuard Vault?

ChainGuard 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.

What is Guardian Attestation?

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.

How does the dual-device security model work?

ChainGuard'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 ChainGuard 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.

What happens if I lose access to one of my devices?

ChainGuard 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.

How do I deploy my ChainGuard Vault?

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.

Can I deploy vaults on multiple blockchain networks?

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 ChainGuard dashboard. Your ChainGuard Identity and KYC verification work across all networks, so you don't need to repeat verification for each chain.

What's the difference between Base Chain Setup and Extended Multi-Chain Setup?

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.

How do I deposit assets into my vault?

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.

How do I withdraw assets from my vault?

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 ChainGuard 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.

Do vault deposits and withdrawals cost gas fees?

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 ChainGuard 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.

Can I use my vault for gasless transactions?

Yes! When you interact with dApps or platforms using ChainGuard 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).

What is the three-address recovery system?

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) ChainGuard 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.

How long is the recovery cooldown period?

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.

How does the vault integrate with other ChainGuard services?

ChainGuard Vault is a core part of the ChainGuard ecosystem and integrates seamlessly with: 1) ChainGuard Identity - Your vault is linked to your unified Web3 identity, 2) ChainGuard OAuth - Vault transactions can be used for dApp authentication, 3) ChainGuard 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.

Can I use my vault with external dApps?

Yes! When connected dApps integrate ChainGuard, 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 ChainGuard. All transactions are protected with 2FA or even 3FA (email, password, 1FA, QR code scan with ChainGuard 2FA). Initiating transactions through OAuth requires an additional QR code scan and wallet signature. This provides better security than traditional wallet connections.

What blockchain networks support ChainGuard Vault?

ChainGuard 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.

Single Point of Failure

Traditional wallets can be drained if your private key is compromised. Our multi-signature system requires two separate approvals, making theft nearly impossible.

Fragmented Gas Tokens

Multi-chain setups typically require wrapped tokens on each chain to pay for gas, fragmenting your assets across networks. Our gasless credit system works seamlessly on every chain, eliminating the need for separate gas tokens on each blockchain.

Cross-Chain Fragmentation

Managing assets across Base, Arbitrum, Optimism, Polygon, and Ethereum requires multiple wallets and constant switching. Our vault works seamlessly across all supported chains from one unified interface.

Lost Access Recovery

Lose your wallet? Traditional solutions mean permanent loss. Our three-address recovery system allows any two addresses to recover the third after a security cooldown, giving you peace of mind without sacrificing security.

Complex Security Setup

Enterprise-grade security typically requires expensive hardware wallets, complex multi-sig setups, and technical expertise. ChainGuard Vault is included in your account—no additional setup, no extra costs, just instant protection.

Guardian Attestation

Enterprise and compliance requirements demand verified, auditable transactions with additional oversight. Guardian Attestation provides an extra layer of verification for ecosystem transactions, ensuring instant compliance, full auditability, and transparent actions that meet regulatory standards.

Why Your Vault is Included in Every Account

Security shouldn't be optional. That's why every ChainGuard account includes a personal vault, available to all users regardless of membership tier. 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.

It's not an add-on; it's a core part of the ChainGuard ecosystem, working seamlessly with Identity verification, OAuth integrations, and mobile 2FA to create a complete security solution. Your vault integrates directly with all ChainGuard services, providing a unified experience across the entire platform.

Think of your vault as your secure digital treasury: store ETH, ERC20 tokens, NFTs (ERC721 and ERC1155), and manage them all from one place. With cross-chain compatibility and multi-signature protection, it's the foundation of your Web3 security infrastructure. Credit-based features like gasless transactions require a monthly subscription tier, which can be added immediately to your account if you want to use those features right away.

Three-Address Security Protocol

Our revolutionary security system uses three separate addresses to create an impenetrable defense mechanism. Your Primary Address is the only one that can interact with the Vault contract on-chain, but every action requires an off-chain signature from your 2FA Address in the ChainGuard app. The Secondary Address provides recovery protection - any two addresses working together can reset the third after a security cooldown, ensuring you never lose access while maintaining maximum security against sophisticated attacks.
