Why Iran’s Nobitex Remains Off OFAC SDN List

Blockchain analytics firms recorded roughly $5 billion in volume through Nobitex between 2025 and March 2026, and one analysis found inflows to Nobitex addresses exceeded the combined total for Iran’s next ten largest exchanges. The platform reports about 11 million users, roughly 12% of the country’s population, and provides spot and margin trading, yield products, liquidity pools, digital gift cards and crypto-collateralized lending.

Investigations have linked the exchange to influential domestic networks and to state activity. Founders have been reported as connected to a prominent political and clerical family. An early investor served in a senior role at a company that was later sanctioned for arranging flights tied to military drone transfers. Analytics firms have also tied wallets associated with Nobitex to groups and entities under international scrutiny and to a sanctioned foreign exchange.

Blockchain investigators identified state-directed use of the platform. One analysis detailed purchases of the USDT stablecoin by Iran’s central bank totaling at least $507 million routed through a broker in the United Arab Emirates and sent primarily to Nobitex addresses. Those transactions enabled conversion of stablecoins into rials outside the international banking system.

A leak of portions of Nobitex’s source code and internal documents in 2025 included features described as designed to limit detection. The leaked material showed modules for generating stealth addresses, batching and splitting transactions, switching endpoints and specific logic aimed at avoiding compliance checks. An internal document outlined tactics to evade Western blockchain surveillance tools.

U.S. sanctions policy provides context for why the exchange has not been individually named on the Treasury’s Specially Designated Nationals list. The Treasury has stated that Iranian digital-asset exchanges are treated as blocked financial institutions even if they are not listed by name. For platforms incorporated and operating inside Iran, prohibitions on U.S. persons already restrict formal access. An SDN designation, however, can trigger secondary sanctions on non-U.S. counterparties, support bulk asset freezes by stablecoin issuers and prompt foreign exchanges and over-the-counter desks to sever ties.

Officials and analysts point to several factors shaping Treasury actions. The department has applied targeted measures such as sanctions on specific blockchain addresses, designations of exchange houses linked to illicit revenue streams, and sanctions on individuals and offshore brokers. One analyst noted the high concentration of ordinary users on Nobitex, saying separating regime-directed flows from retail users is difficult because assets are commingled. Analysts also note that naming a domestic platform may have limited effect without concurrent measures against the external intermediaries where funds leave Iran.

The U.S. Treasury has not publicly explained why Nobitex has not been added to the SDN list.
