What is SDN List?

Also known as: Specially Designated Nationals and Blocked Persons List

The SDN List (Specially Designated Nationals and Blocked Persons List) is OFAC's list of individuals, entities, vessels, and — increasingly — cryptocurrency wallet addresses whose assets are blocked and with whom U.S. persons are generally prohibited from dealing. Screening counterparties against the SDN List is the core of sanctions compliance.

Screening for SDN List-related risk is exactly what SanctionsAI automates — a single API (HTTP, CLI, or MCP) that screens names and wallets against OFAC lists before your agent pays. Free tier, no key: see the docs →
