According to analyst Specter, Tether has frozen 4 TRON network wallet addresses, involving a total of approximately $131 million USDT. On-chain data indicates that most of these funds were withdrawn from payment service provider DTC Pay and cryptocurrency exchange Bitso. The wallet addresses have been linked to the Islamic Revolutionary Guard Corps (IRGC) and the Central Bank of the Islamic Republic of Iran (Bank Markazi Jomhouri Islami Iran), both of which are under OFAC sanctions.

U.S. Treasury Secretary Scott Bessent confirmed the move in a post, saying it is intended to combat Iran's illicit financial activities and its abuse of digital assets. He added that the Treasury will continue to track illicit fund flows and cut off the Iranian regime's illegal revenue channels.
