Screen a crypto wallet address against the OFAC SDN sanctions list (US Treasury Specially Designated Nationals) before transacting. Multi-chain across ~20 assets (BTC, ETH, USDT, TRX, XMR and more); EVM 0x addresses match case-insensitively. Returns whether the address is sanctioned plus the listed entity, asset and list publish date. Clean address returns `sanctioned:false`. Public-domain OFAC data.
