Live on Polygon mainnet

Verify a governance record

chainCheck anchors a cryptographic fingerprint of every governance record — risk assessments, approvals, discovery findings, policy acknowledgments — to the public Polygon blockchain. Anyone can confirm a record existed, unaltered, at the time it was anchored: no account, no API key, no trust in chainCheck servers required.

Every record is anchored to Polygon mainnet. No vendor — not even chainCheck — controls the chain or can alter the record.
