Publish a deterministic claim about a Base proxy and let the market try to break it. You assert that a contract's implementation slot held one address across a block range, fund a reward for whoever finds a block where it did not, and Tereno writes the claim onchain and adjudicates counterexamples by historical storage reads. If nobody collects before your deadline, you get a reproducible survival receipt: not an audit, but proof the claim stood in public with money on it.Overview
