An individual or entity whose property and interests in property are blocked under OFAC sanctions programs.
When assets are blocked, they cannot be transferred, paid, exported, withdrawn, or otherwise dealt in. Any transaction involving a blocked persons property is prohibited. This includes transactions initiated by AI agents on behalf of US persons.
A blocked person is any individual or entity whose property and interests in property are frozen under US economic sanctions authorities. Blocked persons appear on the OFAC SDN List or are described in an Executive Order or OFAC regulation.
Blocked persons include designated terrorists, drug traffickers, malicious cyber actors, entities linked to sanctions evasion, and officials from sanctioned governments. Over 10,000 individuals and entities are on the current SDN List.
AI agents that move money must check counterparties against the SDN List before each transaction. Paying a blocked person triggers strict liability penalties. The agentmail API screens wallets, names, and countries against the full SDN List in under 100ms.
agentmail covers 19,086 sanctioned names, 782 crypto wallets, and 16 embargoed jurisdictions from the OFAC SDN List.
