SDN List

The Specially Designated Nationals (SDN) list is OFAC's register of individuals, entities, and crypto addresses whose assets are blocked and with whom U.S. persons may not transact.

The SDN list names parties subject to blocking sanctions; when a listing carries a digital-currency identifier, the associated wallet is itself off-limits and any incoming or outgoing transfer must be rejected. Because bad actors rotate addresses, screening a single hop is not enough. Sanctions screening on our platform checks counterparties against SDN and related lists, and multi-hop fund-flow tracing plus an exposure breakdown by category surface funds that reached an address only after passing through an SDN-linked cluster, so you catch indirect exposure that a flat blocklist lookup would miss.
