Tether Faces Lawsuit Over Alleged Illegal Freezing of $42.4 Million in USDT

Two Thai entrepreneurs have launched a lawsuit against Tether in the Southern District of New York, claiming the company unlawfully froze approximately $42.4 million in USDT. Their complaint alleges that this action was taken without a court order, at the informal request of a federal agent.

Nutthawat Rukthammachalern and Natthawat Kasamvilas are calling for both the restoration of access to their funds and compensation for damages and profits they believe were accrued from the tokens’ backing reserves. The USDT in question is held across ten Ethereum addresses, which Tether reportedly blacklisted last October.

According to the lawsuit, the blacklisting occurred without any legal warrant, although a federal magistrate judge later issued a seizure warrant ordering Tether to burn the frozen tokens and mint new ones for transfer to a government wallet. The plaintiffs argue that this warrant does not retroactively justify the freeze and prohibited Tether from destroying the original tokens before a forfeiture judgment.

Tether has the capability to blacklist addresses across multiple networks, rendering blacklisted tokens visible but untransferable. Earlier this year, Tether revealed its collaboration with law enforcement agencies globally, claiming to have frozen over $4.4 billion in assets tied to illegal activities. CEO Paolo Ardoino emphasized the firm’s commitment to acting against illicit activities linked to USDT, stating that the company does not serve as a refuge for such actions.
