Tether has assisted in freezing approximately $550 million worth of USDT linked to Iranian sanction-related networks this year.

Tether said that since 2026, the company has assisted U.S. and international law enforcement agencies in freezing approximately $550 million worth of USDT linked to Iran’s central bank and Iranian sanction networks. In April this year, Tether froze over $344 million worth of USDT in two addresses based on information from the U.S. Office of Foreign Assets Control (OFAC) and U.S. law enforcement; in July, as the U.S. Treasury expanded sanctions against Iran’s central bank, the company froze an additional $130 million worth of USDT in four TRON addresses, bringing the total of the two actions to roughly $550 million. To date, Tether has collaborated with more than 340 law enforcement agencies across 67 countries and regions, supporting over 2,900 investigations—more than 1,600 of which involve U.S. law enforcement. The company has cumulatively frozen over $4.9 billion in assets, with more than $2.4 billion linked to U.S. law enforcement. Tether CEO Paolo Ardoino noted that public blockchains allow law enforcement to trace fund flows, adding that Tether can implement freezing measures upon receiving credible information from law enforcement and will continue to assist in combating sanction evasion, terrorist financing, and other financial crimes.
