Verify an Anchored Record.
Documents, desk alerts, books and rule changes are anchored on Polygon each hour. Drop in the file or paste its fingerprint. The check runs against the Anchor contract on Polygon mainnet and returns the exact time it was anchored, or tells you it never was.
A public, permanent fingerprint
Anchored on Polygon: a public, permanent fingerprint. The document itself stays private. Only its 32-byte SHA-256 fingerprint is anchored, so existence, integrity and date are provable while the content stays with you.
Drop the file, or use your certificate
Drop the file here and it is fingerprinted in your browser. Every certificate also prints the batch and its Merkle proof, so the check works even without this site’s lookup.
Independently checkable
The result is a direct read of the Anchor contract on Polygon mainnet. You can repeat the same check yourself on any public explorer. No trust in this site required.
Need your own record anchored?
Anchored Proof turns a private document into a record this page can check: fingerprinted, sealed, and anchored on Polygon in the next hourly batch. The document itself stays private.
