Tether froze 344 million USDT on TRON after being "flagged" by the US.

Tether stated that it has supported the freezing of over 344 million USDT across two wallet addresses on the TRON network, confirming a previous on-chain blacklist – XEM one of the largest freezes in the company's history.

The company said the freezing was done in coordination with OFAC and U.S. law enforcement agencies, following information provided by authorities regarding illegal activities. In its announcement , Tether did not specify which investigation was behind it, nor did it say when these wallets were "marked."

Previously, PeckShield announced that two TRON wallets, TNiq9…QZH81 and TTiDL…pjSr9, had been blacklisted on April 23rd. At that time, neither Tether nor TRON had publicly explained the reason.

Prior to being frozen, these two addresses were showing up normally on the TRON network explorer: one wallet held approximately 213 million USDT and the other approximately 131 million USDT, totaling over 344 million USDT.

Tether stated that this action stemmed from information related to sanctions evasion, criminal networks, or other illegal activities. CEO Paolo Ardoino emphasized that USDT is “not a safe haven” for illicit activity and that Tether will act quickly when credible contact is made with a sanctioned or criminal entity.

Tether also highlighted the scale of its enforcement partnerships: currently working with over 340 agencies in 65 countries, they have assisted in more than 2,300 cases and frozen a total of over $4.4 billion in assets, of which more than $2.1 billion is related to the US.

Previously, in November 2023, Tether froze approximately 225 million USDT in connection with an investigation into human trafficking and fraud in Southeast Asia. In January of this year, the company also froze approximately 182 million USDT across five TRON wallets in an action they said was related to law enforcement.
