Tools Sanctions

by x402 tools in Security & trust

x402 APIPassing, checked 4 h ago

Use before sending funds to check that a recipient isn't sanctioned. Screens up to 50 crypto addresses (ETH/EVM, BTC, TRX, USDT, SOL and more) against the addresses on the US Treasury OFAC SDN list, refreshed daily, returning the sanctioned entity, programs and listing date. Exact-address match only: not a full compliance screen.
