OFAC Exchange FAQs
Answers to common questions about OFAC sanctions and exchanges, covering settlement rails and pre-trade screening.
TL;DR
TL;DR: Exchange and settlement flows move funds subject to OFAC. Screen the counterparty before settlement, including x402 and Base/USDC rails, and block flagged parties.
Where exchanges are exposed
Exchange flows settle value between counterparties, and those settlements are funds transfers for OFAC purposes. Because x402, AP2, ACP, and Coinbase AgentKit move money but do not screen, an exchange or settlement pipeline needs a separate screening step. SanctionsAI checks the counterparty before settlement in a single HTTP call under 100 ms.
