OFAC Sanctions Screening API
Daily OFAC SDN screening for wallets, names, and entity matches
Daily-ingested sanctions intelligence from the U.S. Treasury OFAC SDN and address lists. Screen crypto addresses and legal entities for sanctions exposure, monitor aliases, and track digital-currency wallet indicators for AML/compliance workflows.
How customers use this
Crypto exchange deposit screening
Screen every deposit address against the OFAC SDN list before crediting funds. Catch sanctioned wallets at the point of entry to stay compliant and avoid regulatory action.
DeFi protocol wallet blocking
Block sanctioned wallets from interacting with your smart contracts. Integrate the API into your frontend or middleware to reject transactions from flagged addresses before they execute.
Daily batch screening for compliance teams
Batch-screen your entire customer address book daily against updated OFAC lists. Catch newly sanctioned entities that may already be in your system and generate audit-ready reports.
