Fast check of a payee before an agent pays it
Fast check of a payee before an agent pays it: OFAC SDN match on the address, account type (wallet, delegated wallet or contract) and nonce on Base, Ethereum, Arbitrum, Optimism or Polygon, and optionally the payee domain's age and trust flags. One block, review or pass verdict with reasons. Screening aid, not legal advice. Use before an x402 or USDC payment to an unfamiliar address; holdings and wallet heuristics: check_counterparty.
