Base Pre-Sign Guard — simulate before you sign
Agentropolis kit (first-party)
Simulate a Base transaction (or decode a Permit / Permit2 signature) before an agent signs it: signer asset changes, approvals granted (unlimited, Permit2, setApprovalForAll) and drainer-pattern flags → ok / warn / block. Missing data defaults to warn.
