Nobitex, Iran's largest cryptocurrency exchange, has not been added to the U.S. Office of Foreign Assets Control's (OFAC) Specially Designated Nationals (SDN) List, despite investigators linking approximately $5 billion in observed flows and around 11 million users to the platform. According to NS3.AI, Elliptic reported that Iran's central bank acquired at least $507 million in USDT through a broker in the UAE, with the assets primarily directed to Nobitex. OFAC clarified that Iranian digital asset exchanges are already regarded as blocked financial institutions, even if they are not individually named on the SDN list.
