The U.S. Treasury Department on Tuesday sanctioned Nobitex, Iran’s largest digital asset exchange, accusing the platform of helping Tehran evade sanctions and facilitate terrorist financing and ransomware attacks. 

In a statement, the Treasury Department’s Office of Foreign Assets Control (OFAC) accused Nobitex of processing more than half of all Iranian digital asset inflows in 2025 and processing payments connected to Iran’s  Islamic Revolutionary Guard Corps. OFAC also designated three other Iranian digital-asset exchanges—Wallex, Bitpin, and Ramzinex—as part of what the department described as its “Economic Fury” campaign to increase pressure on Iran’s financial networks.

The department also accused Nobitex of helping Iran’s central bank access hundreds of millions of dollars in stablecoins to support the rial, while enabling regime insiders to reach international digital asset exchanges and evade sanctions across multiple jurisdictions.

The agency designated Nobitex chairman, co-founder, and former chief executive Amir Hossein Rad, current chief executive Seyed Ali Khoee, and co-founders Seyed Mohammad Ali Aghamir Mohammad Ali and Seyed Mohammad Aghamir Mohammad Ali. Treasury said Rad helped restore Nobitex operations after a $90 million hack in June 2025.

Wallex, Iran’s second-largest digital asset exchange by volume, received 12 percent of Iranian digital asset inflows in 2025 and facilitated transactions linked to the IRGC, according to U.S. officials. Bitpin received 10 percent of such inflows and processed millions of dollars in transactions, including IRGC-linked activity, while Ramzinex processed more than $2.45 billion in transactions and was used for sanctions evasion, OFAC said. 

The U.S. State Department’s Rewards for Justice program is also offering up to $15 million for information leading to the disruption of financial mechanisms used by the IRGC and its branches, Treasury said.

In a separate action Tuesday, Treasury sanctioned two rebel commanders in the Democratic Republic of the Congo: Gustave Kubwayo, a commander in an intelligence and special operations unit of the Democratic Forces for the Liberation of Rwanda, and John Imani Nzenze, an intelligence chief in the Rwanda-backed March 23 Movement.

The department noted that FDLR and M23 are U.S.- and U.N.-designated armed groups with long records of human rights abuses and regional destabilization.
