Tether has frozen more than $344 million worth of USDT in coordination with U.S. authorities, marking one of the largest enforcement actions involving a stablecoin to date.
According to the company, the freeze was carried out alongside the Office of Foreign Assets Control (OFAC) and federal law enforcement agencies.
The action targeted blockchain wallet addresses that were flagged for alleged links to illicit activities, including sanctions evasion and financial crime.
The funds were held on the Tron blockchain and have now been rendered inaccessible following the freeze.
Tether has the ability to block transactions at the smart contract level, allowing it to prevent the movement of tokens associated with suspicious or unlawful activity.
The company stated that the move is part of its ongoing efforts to support global law enforcement and enhance transparency within the digital asset ecosystem.
Tether emphasized that it actively collaborates with authorities worldwide to identify and restrict the use of its stablecoin in illegal operations.
The scale of the freeze highlights the growing role of centralized stablecoin issuers in enforcing regulatory compliance.
While cryptocurrencies are often associated with decentralization, stablecoins like USDT operate with built-in controls that allow issuers to intervene when required.
Tether also noted that it has worked with hundreds of law enforcement agencies across multiple jurisdictions and has previously frozen billions of dollars in assets linked to criminal investigations.
The latest action comes amid increasing regulatory scrutiny of the crypto sector, particularly around the use of digital assets in money laundering and sanctions evasion.
Authorities have been pushing for stronger oversight and cooperation from industry participants to address these risks.
By executing large-scale freezes in coordination with regulators, Tether is positioning itself as a key partner in global compliance efforts, while also demonstrating the extent of control stablecoin issuers maintain over their networks.
