Tether Freezes $344M USDT on Tron in Coordination With US Authorities

Tether froze $344 million in USDT across two Tron wallets on April 23, following requests from U.S. law enforcement and the Office of Foreign Assets Control (OFAC), the stablecoin issuer said in a statement on Thursday.

The action marked the largest single freeze in Tether's history, dwarfing the previous high of $182 million across five Tron wallets in January 2026.

The wallets were flagged for alleged links to illicit activity. Blockchain analytics firm AMLbot said the addresses appeared in scam-related documents and posts. Tether did not specify who controlled the wallets or the nature of the activity.

The freeze comes as the Financial Action Task Force (FATF) warned that stablecoins are increasingly used in sanctions evasion and money laundering. The global watchdog flagged the growing role of digital dollars in illicit flows in a report published this month.

Tether said it works with law enforcement when wallets are tied to sanctions evasion or criminal networks, and has supported more than 2,300 cases across 340 agencies in 65 countries. The company is separately preparing for its first full audit of reserves, working with KPMG, as it pushes deeper into the U.S. market under former White House crypto advisor Bo Hines.
