TrustAgent

Smart contract security check before you approve or pay an address: reads the bytecode, behind proxies too, for privileged functions (mint, pause, blacklist, upgrade), dangerous opcodes and protocol type, and checks whether a single key holds those powers. Adds OFAC SDN screening, who funded the address, sybil-filtered ERC-8004 reputation for agents and a 0-100 score with proceed / hold / block. Static analysis, not an audit. Free: GET /v1/verify. Trial: /v1/trial.
