The U.S. Treasury Department has blacklisted several Iranian cryptocurrency exchanges, including Nobitex, Wallex, Bitpin, and Ramzinex, along with some executives. According to NS3.AI, this action follows the seizure of approximately $1 billion in cryptocurrency from Iranian exchanges and wallets since the onset of the conflict with Iran. The Office of Foreign Assets Control (OFAC) has added these entities to the Specially Designated Nationals (SDN) list, effectively prohibiting U.S. entities and individuals using the U.S. dollar financial system from providing financial services to these platforms.
