Independent verification

Check an IPME certificate against the Base blockchain. Everything runs in your browser — IPME’s servers and database aren’t involved.

How it works: the blockchain holds only SHA-256(file fingerprint ‖ owner wallet ‖ salt). This page computes the same value from your file and the certificate’s wallet and salt, reads the attestation from Base, and checks they are equal, that IPME issued it, and that it hasn’t been revoked.
