onchain build provenance · monad testnet

Your build, no cap.

Onchain build-provenance protocol — auto-anchors commit fingerprints to Monad so timelines are verifiable, not claimed.

Git timestamps can be rewritten. Rebases lie. Chain time can't.

The whole flow: one push, one anchor, one badge.

Register

Connect your GitHub repo and sign once. No keys to generate, no CI to configure — first registrant wins ownership onchain.

Just push. Our hosted relayer anchors every commit to Monad automatically — zero secrets in your repo, zero manual effort.

Judges open a public timeline and one green badge. No wallet needed, nothing to trust but the chain.
