We pin what projects promise to what the chain shows.
Independent on-chain checks for crypto projects and AI agents. Every finding is pinned to a block, linked to its transaction, and published either way.
If something doesn't match, you hear it from us first, with 12 hours to answer. Then the record goes public with your answer beside it.

Seven checks on Ethereum, Base, Robinhood Chain and Solana: who controls a contract, where a vault's money went, whether an agent's income is real. No account, no invoice; charged only when the check finishes.
