Tether said it supported the freezing of nearly $550 million in Iran-linked USDT during 2026 as the U.S. Treasury expanded its crackdown on sanctions-evasion networks. More than $344 million was frozen in April and over $130 million in July, involving wallets identified by U.S. authorities as connected to Iran’s central bank and sanctions network. CEO Paolo Ardoino said USDT is not a safe haven for sanctioned actors, terrorist organizations or criminal networks. Tether also said it works with more than 340 law-enforcement agencies across 67 countries and has helped freeze over $4.9 billion in assets cumulatively.
