OFAC
OFAC — the Office of Foreign Assets Control — is the US Treasury office that administers and enforces economic sanctions. It publishes the Specially Designated Nationals (SDN) list and other sanctions lists that financial institutions screen against. OFAC compliance is strict liability: transacting with a sanctioned party is a violation regardless of intent.
By Krisan Nichani, Chief Compliance OfficerLast updated July 2026
OFAC sanctions come in two broad forms: country-based programs restricting dealings with whole jurisdictions, and list-based designations naming specific people, entities, vessels, and wallet addresses. Institutions must block or reject matched transactions and report them — which is why screening runs before settlement, at onboarding and again at every payment as lists change.
On Infinite, OFAC screening is where every payment starts: every counterparty is screened before funds move, on every rail — stablecoins included — and the screening record lands in the transaction’s documented case file.
Frequently asked questions
What is the SDN list?
OFAC’s list of Specially Designated Nationals and Blocked Persons — individuals and entities US persons are generally prohibited from transacting with. It is the primary list US institutions screen against. Sanctions screening
Who must comply with OFAC sanctions?
All US persons — citizens, permanent residents, and US-organized entities — wherever they are located. In practice the reach is broader: transactions denominated in US dollars or routed through the US financial system can bring non-US parties within OFAC’s jurisdiction.
When does OFAC screening happen?
At onboarding and again at every payment, because lists change constantly — a clean counterparty yesterday can be a designated one today. Matches must be blocked or rejected and reported. Global compliance
