Verify

Check an agreement yourself.

This runs entirely in your browser — nothing is uploaded anywhere, TIPISTAMP's server is never trusted or even asked. It recomputes the statement's fingerprint, checks every signature against its own embedded public key, and confirms every party actually signed.

Try it now

Load the real agreement featured on the homepage, or check a bundle.json someone sent you.

Prefer the command line, or want to check this offline with nothing but PHP? Download the bundle from any agreement page and run php agreement-verify.php bundle.json — same checks, same result, no browser required.
