Check whether a mined Base transaction did what your agent meant it to do

Check whether a mined Base transaction did what your agent meant it to do. Fetches the receipt, decodes its ERC-20, ERC-721 and ERC-1155 transfer and approval logs, and reports each declared movement as matched, missing or short, with the observed amount beside the expected one. Catches reverts, success with no effect, fee-on-transfer skims and transfers to recipients you never named. Returns unknown rather than guessing. Not a guarantee that a transaction was safe.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
