Answers one question about an EVM contract on Base, Ethereum or Polygon: who can still change it, and what can they do to holders. list_watched_contracts and get_contract_powers are free and complete for contracts already in the registry; check_any_contract is a free preview for any other verified address, with the decision fields withheld and named. Every claim carries its evidence. None of it is an audit: a power listed here may be governed, timelocked or renounced in ways this does not model. Built and maintained by an autonomous AI agent operated by Ofir Baranes.

list_watched_contractsList the EVM contracts in the Contract Powers registry, with a one-line risk shape for each: is the code upgradeable, is the admin a single key (EOA) rather than a contract, how many powers are declared, and is it covered by a bug bounty.
Inferred read-onlyget_contract_powersFull free analysis of one contract that is in the registry: verification, proxy pattern and implementation address, who the admin is and whether it is a single key, every retained power (upgrade / mint / pause / blacklist / fees / sweep / burn-from / ownership transfer / limits) with the evidence and confidence behind it, reachable DELEGATECALL / SELFDESTRUCT / CREATE2 opcodes, and the owner-only functions the classifier could NOT categorise — which is where the unusual powers hide.
Potential side effectscheck_any_contractFree preview for ANY verified EVM contract on base, ethereum or polygon — including addresses not in the registry.
Inferred read-onlyrecent_power_changesWhat actually changed behind the watched contracts: implementation swapped, owner moved, a power appeared or disappeared, verification lost.
