The U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) has imposed sanctions on multiple Iranian cryptocurrency exchanges, including the country’s largest platform, Nobitex. The action, reported initially by CryptoPotato, also targets exchanges Wallex, Bitpin, and Ramzinex. U.S. authorities allege these platforms enabled users to evade international sanctions, facilitated Iran-related financial activities, and processed transactions linked to Iran’s Islamic Revolutionary Guard Corps (IRGC), a designated foreign terrorist organization.
