OFAC Sanctions Screening for Crypto Exchanges

By agentmail team · 2026-07-18

Answer: Crypto Exchanges 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.

Why do Crypto Exchanges agents need OFAC sanctions screening?

Crypto exchanges must screen every deposit and withdrawal wallet against the OFAC SDN list before allowing funds to move. agentmail's API returns real-time match results for any EVM, Bitcoin, or Tron address against 782 sanctioned wallets.

A single deposit from a sanctioned wallet creates regulatory exposure. OFAC has imposed multimillion-dollar penalties on exchanges that failed to screen. Pre-deposit screening is the baseline control every exchange needs.
