Answer: NFT Marketplaces agents screen counterparties against the OFAC SDN list (19,086 names, 782 crypto wallets, 16 embargoed jurisdictions) via a single API call before every payment. A "clean": true response means proceed; "clean": false means halt. The check runs in under 100ms and the free tier covers 5 checks/day with no API key.
NFT marketplaces handling on-chain transactions must screen every wallet address against OFAC sanctions lists. A single sanctioned wallet interaction can trigger asset freezes, regulatory scrutiny, and reputational damage.
The pseudonymous nature of crypto wallets means you cannot rely on identity-based screening alone. OFAC-listed wallets are updated regularly, and interacting with them is a strict-liability violation.
