Tether froze $344 million in USDT (USDT) across two Tron wallets in coordination with the Office of Foreign Assets Control and U.S. law enforcement, the company confirmed on April 23.
The action targets addresses flagged for activity tied to sanctions evasion and criminal networks. It represents Tether’s largest single enforcement action to date.
Freeze Tied to Active U.S. Investigations
The two blacklisted wallets held approximately $212.9 million and $131.3 million respectively. Tether said U.S. authorities shared intelligence linking the addresses to unlawful conduct before the freeze was executed, preventing further movement of funds
“USD₮ is not a safe haven for illicit activity. When credible links to sanctioned entities or criminal networks are identified, we act immediately and decisively,” read an excerpt in the announcement, citing Tether CEO Paolo Ardoino who framed the response as part of a broader compliance posture.
Tether now works with more than 340 law enforcement agencies across 65 countries. That cooperation has supported over 2,300 cases globally, with more than 1,200 tied to U.S. authorities.
Surpasses Previous Record
The $344 million freeze dwarfs the previous high of $182 million blacklisted across five Tron wallets in January 2026.
Tether has now frozen more than $4.4 billion in total assets linked to illicit activity, with over $2.1 billion connected to U.S. law enforcement.
The U.S. Department of Justice has previously acknowledged Tether’s role in enforcement actions that led to seizures of nearly $61 million and approximately $225 million tied to pig butchering fraud.
The latest freeze reinforces the argument that public blockchains offer investigators a traceable record that traditional cash transfers cannot.
