Compliance & KYC

CrowdProof provides privacy-preserving compliance tools for regulated industries.

Age Verification (ZK-based)​

Prove a user is 21+ without storing or transmitting any PII:

POST /api/v1/compliance/age-verify
Content-Type: application/json

{
  "walletAddress": "0x1234...",
  "minimumAge": 21,
  "jurisdictionCode": "US-CO"
}

The user verifies once, then only the ZK proof is presented on subsequent visits.

KYC Flow​

1. Initiate KYC​

POST /api/v1/compliance/kyc/initiate
Authorization: Bearer <JWT>
Content-Type: application/json

{"did": "did:ethr:0x1234...", "provider": "persona"}

Returns a sessionUrl — redirect the user to complete identity verification.

2. Check Status​

GET /api/v1/compliance/kyc/did:ethr:0x1234.../status

Status values: pending, approved, rejected

OFAC Sanctions Screening​

GET /api/v1/compliance/sanctions/0x1234...
