Tether Hit With $42.4M USDT Lawsuit Over Freeze Before Court Warrant

Two Thai businessmen sued Tether in federal court in Manhattan, alleging that it froze 42,417,785.62 USDT before a seizure warrant had yet been issued by U.S. authorities. Nutthawat Rukthammachalern and Natthawat Kasamvilas filed the complaint on August 31.

It mentions 10 Ethereum addresses blacklisted on October 30, 2025. While the claims remain unproven, Tether has not issued a statement as of September 2.

The plaintiffs claim that the freeze was informally requested by an HSI agent and that no warrant, subpoena, court order, or other process of law had been issued to support the action.

Kasamvilas claims to have not known about the freeze until attempting to make a transaction, and that he was sent to an HSI agent’s email address when he contacted Tether.
