Overview

Sanctions-screen a crypto wallet address against the US Treasury OFAC SDN list's published Digital Currency Addresses (BTC/ETH/USDT/XMR and more). Exact match — returns whether the address is sanctioned, and for any hit the listed entity name, OFAC programs, source id, and the currency the address was listed under. Compliance check before transacting. Distinct from crypto.address-safety (GoPlus behavioral risk) — this is regulatory sanctions.
