OFAC Wallet FAQs
Answers to common questions about OFAC sanctions and crypto wallets, covering designation and pre-payment screening.
TL;DR
TL;DR: OFAC can designate wallet addresses as blocked property. Screen the address against the SDN List before paying, and stop on a BLOCK result.
How wallets get flagged
OFAC lists specific crypto wallet addresses on the SDN List, treating them as blocked property. Once listed, US persons generally cannot transact with them. SanctionsAI indexes 947 OFAC-listed crypto wallets across Ethereum, Bitcoin, and Tron, so the sanctions_check tool can match an address before funds move.
