How Identity Verification Works
- Connect your wallet and complete Sign-in with Ethereum (SIWE) (this may happen on the referrer’s application)
- Scan QR code or click the verification link
- Complete KYC/KYB with partner identity provider
- Verification status will be sent to the referring application
Data Storage & Access
When you complete identity verification, your personal documents and information are stored securely by KYC/KYB providers who handle all personally identifiable information (PII) processing. These providers send only verification results to Predicate—never your actual documents or personal details. Predicate receives and stores only your verification status linked to your wallet address, then provides cryptographic proofs to applications when needed. Applications that integrate with Predicate receive only these cryptographic proofs of your verification status and cannot access your documents or personal information.| What We Store | What We Do Not Store |
|---|---|
| Wallet address | Documents (passport, driver’s license, etc.) |
| Verification status (verified/not verified) | Photos |
| KYC/KYB provider used | Personal details |
| Verification timestamp | Address information |
