PUBLIC VERIFICATION
Verify a credential.
Paste a credential ID to check authenticity, integrity and revocation against Polygon. No account, no wallet.
VERIFY IN BULK
Check a whole list at once
Paste up to 50 credential IDs — ideal for an employer screening a batch of candidates. Need to verify thousands programmatically? Use the /api/v1/verify API with a key.
HOW VERIFICATION WORKS
01
Recompute the fingerprint
We re-derive the credential's keccak256 hash from its stored data. Change one character and the hash no longer matches — that's a tamper.
02
Check the Merkle proof
We prove that fingerprint is committed inside the batch anchored to Polygon — a cryptographic receipt no one can forge.
03
Check revocation
We confirm the issuer hasn't rescinded it on-chain. Revocation is permanent and public.
WHAT THE RESULTS MEAN
Verified
Authentic, untampered, anchored on-chain.
Revoked
Rescinded by the issuer — no longer valid.
Tampered
Data doesn't match the on-chain fingerprint.
Pending
Issued but not yet committed to Polygon.
Not found
No credential with that ID.
