What is SDN List?
The SDN List, or Specially Designated Nationals and Blocked Persons List, is OFAC's public list of individuals, companies, and other parties whose property is blocked under U.S. sanctions. It is unusual among sanctions lists in publishing cryptocurrency wallet addresses for some designated parties, in machine-readable formats that screening systems can load directly.
