Try it yourself

1Break a rule

Act like a dishonest issuer. Each button sends a real transaction on Solana devnet.

2Watch it get caught

In about 5 to 10 seconds a check on the right turns red and a proof appears.

3Start over

Already red from someone else's try? Make a fresh token (about 2 minutes).

Check it yourself

Recompute a proof's fingerprint with scripts/verify_proof.py.
Open its transaction and re-run the same SQL rule from the open-source repo.
Compare with the fingerprint our Solana program stored. Evidence, not an audit opinion.
