The U.S. Treasury's Office of Foreign Assets Control (OFAC) has announced sanctions against Nobitex, Iran's largest cryptocurrency exchange, for facilitating payments related to terrorist activities.

Nobitex is believed to have helped evade economic sanctions and also facilitated transactions linked to the Islamic Revolutionary Guard Corps (IRGC).

Among the transactions, the U.S. authorities found wallets associated with ransomware threat actors related to the IRGC.

“Nobitex has provided significant support to the regime, processing more than 50 percent of all Iranian digital asset inflows in 2025 and facilitating payments tied to Iran’s terrorist activities, sanctions evasion efforts, and Islamic Revolutionary Guard Corps (IRGC)-linked transactions, including activity associated with IRGC-affiliated ransomware actors,” the Treasury said.

“Nobitex also helped the Central Bank of Iran access hundreds of millions of dollars in stablecoins used to prop up the plummeting value of the Iranian rial, while enabling regime insiders to access international digital asset exchanges and evade sanctions across multiple jurisdictions.”
