Is this Base contract safe to interact with?
Is this Base contract safe to interact with? Detect whether an address has no code, is an upgradeable proxy, or is currently paused, and get a bounded allow, review or block trust verdict with evidence and block freshness before you call it. Positive-sum by design: $0.03 when nobody has checked this contract yet, $0.02 on a shared bytecode fingerprint, $0.01 once another agent has computed the full answer — and the wallet that computed it first earns a share of every reuse.
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.
