Certificates
Verify a certificate
Enter the number and the SHA-256 printed on a Manci certificate of tokenized interest to see whether it is valid, what it states, who signed it and where it is anchored on chain.

What the check covers
- A number alone shows only whether the certificate exists and whether it is valid or revoked. What it states opens with the SHA-256 printed on the certificate, or its JSON file: whoever checks a certificate holds it.
- Valid means: the operator issued the certificate, its signature by the key shown verifies, and it has not been revoked. A certificate states facts at the slot it names; a holding may have changed since.
- This page never shows a holder's name or identification number. They are part of the signed content: if your copy of the certificate's JSON file matches the SHA-256 here, its holder details are the ones that were signed.
- You can check everything without this site: the SHA-256 of the certificate's JSON (canonical, UTF-8), the Ed25519 signature of the signed message by the signer's key, and the memo of the anchor transaction on a Solana explorer.
