What is ChainGuard Identity?

ChainGuard Identity is a unified Web3 identity system that creates a cryptographically verifiable link between your KYC-verified ChainGuard account, your physical ChainGuard 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 ChainGuard app, providing enterprise-grade security for Web3 asset management.

How does ChainGuard Identity work?

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

What is KYC verification and why do I need it?

KYC (Know Your Customer) verification is a compliance process that verifies your identity through document checks. ChainGuard 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 ChainGuard products and can be used for compliant transactions, regulatory reporting, and enterprise integrations.

How does vault creation work?

ChainGuard 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 ChainGuard account identity.

What is wallet binding?

Wallet binding creates a cryptographically verifiable link between your wallet address and your ChainGuard account. This process requires signatures from both your wallet (MetaMask, etc.) and your ChainGuard 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 ChainGuard app which signs the message, 4) Both signatures are verified on-chain using ECDSA recovery, 5) Wallet is linked to your ChainGuard identity in your user profile.

Why do I need to bind my wallet?

Wallet binding is the critical link that connects your verified ChainGuard identity to your wallet addresses. This creates a three-way binding: your KYC-verified account, your ChainGuard 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 ChainGuard products and dApps.

What is on-chain validation?

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 ChainGuard 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.

How secure is ChainGuard Identity?

ChainGuard Identity provides enterprise-grade security through multiple layers: 1) KYC verification ensures verified identity foundation, 2) Dual signature requirement (wallet + ChainGuard 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.

Can I use ChainGuard Identity with multiple wallets?

Yes! You can bind multiple wallets to your ChainGuard Identity. Each wallet binding follows the same dual signature verification process (wallet signature + ChainGuard 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 ChainGuard 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.

What happens if I lose access to my ChainGuard mobile app?

If you lose access to your ChainGuard mobile app, you can recover access through the three-address recovery system. Any two of your three addresses (Primary wallet, ChainGuard 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.

How does ChainGuard Identity work with other ChainGuard products?

ChainGuard Identity is the foundation that connects all ChainGuard products: 1) ChainGuard Vault uses your identity for multi-signature protection, 2) ChainGuard OAuth uses your identity for dApp authentication, 3) ChainGuard 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 ChainGuard ecosystem - one verified identity works everywhere.

Is my identity information stored on the blockchain?

KYC verification data is processed by third-party providers (Sumsub, Onfido, Jumio) and linked to your ChainGuard 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.

How long does the identity setup process take?

The ChainGuard 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.

Can I use ChainGuard Identity for enterprise compliance?

Yes! ChainGuard 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.

What is the factory/clone pattern and why does it matter?

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.

How does dual signature verification work?

Dual signature verification requires signatures from both your wallet and ChainGuard 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 ChainGuard 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.

What happens if my wallet binding fails?

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 ChainGuard 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.

Can I unbind a wallet from my ChainGuard Identity?

Yes, you can unbind wallets from your ChainGuard 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 ChainGuard app. Unbinding a wallet does not affect your KYC-verified account identity or other bound wallets.

How does ChainGuard Identity compare to other Web3 identity solutions?

ChainGuard 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.

What is the cost of setting up ChainGuard Identity?

The first three steps of ChainGuard Identity setup are completely free: 1) Download app and create account (FREE), 2) Wallet binding and profile (FREE), 3) Choose your path (FREE).

What personal information is collected during KYC verification?

During KYC verification, ChainGuard 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 ChainGuard 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.

How does ChainGuard protect my KYC data?

ChainGuard 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 ChainGuard'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.

What happens to my KYC data after verification?

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.

What encryption algorithm does ChainGuard use for KYC data?

ChainGuard 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.

How does the KYC ID hashing process work?

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.

Where is my encrypted KYC data stored?

Your encrypted KYC data is stored in ChainGuard'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.

Can I access my stored KYC data?

Yes, you can access your KYC verification status and related information through your ChainGuard 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.

What is a combined hash in ChainGuard Identity?

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, ChainGuard account address, vault ID, a unique nonce, and timestamp. The formula is: keccak256(kycIdHash || userAddress || chainGuardAddr || 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.

What is Guardian Attestation and how does it work?

Guardian Attestation is a cryptographic proof that ChainGuard 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, ChainGuard 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 ChainGuard 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.

What data is stored on-chain vs off-chain?

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).

How does ChainGuard Identity integrate with the vault?

ChainGuard 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.

What are the use cases for ChainGuard Identity attestation?

ChainGuard 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 ChainGuard 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.

How long is my KYC verification valid?

Your KYC verification is valid for one year from the date of verification. When you finalize your ChainGuard 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 ChainGuard Identity, wallet bindings, and vault remain active during the renewal process. You'll receive notifications before your KYC expires to ensure continuous service.

Can I view my attestation on the blockchain?

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 ChainGuard dashboard, which provides a user-friendly interface to all your identity and attestation information.

왜 ChainGuard Identity인가

Web3 보안과 규제의 교차점에 위치한 아이덴티티 계층

접속이 아닌 권한을 협상하는 미래

사용자가 요청하면 플랫폼이 승인해주던 단방향 모델은 더 이상 유효하지 않습니다. MiCA, 트래블 룰 등은 자료를 요청하는 모든 주체에게 책임 있는 권한 협상을 요구합니다.

플랫폼은 신뢰 가능한 데이터를 요구하고, 사용자는 어떤 데이터가 왜 요청되는지 투명하게 알고 싶어 합니다. 양측 모두에게 감사 가능한 권한 모델이 필요합니다.

ChainGuard Identity는 이 과정을 단일 UX 안에 통합했습니다. ChainGuard 환경 안에서 사용자가 권한을 승인하므로 피싱이나 외부 팝업이 필요 없으며, 플랫폼은 요구 조건을 충족한 상태로 데이터를 수신합니다.

엔터프라이즈 보안

지갑·앱·KYC 계정을 묶는 삼중 검증 덕분에, 금고 명령은 항상 다중 팩터 인증을 거칩니다.

정책 준수

모든 액션이 온체인으로 남아 금융 규제 기관이나 파트너의 감사 요구에 대응할 수 있습니다.

통합된 Web3 아이덴티티

하나의 ID로 ChainGuard 생태계와 연동 dApp 전반을 아우르며, 로그인·결제·KYC를 단일 파이프라인에서 처리합니다.

불변의 감사 로그

사용자·플랫폼·규제 기관이 신뢰할 수 있는 완전한 감사 추적을 제공합니다.
