Thai businessmen challenged Tether to freeze $42.4 million USDT

As a result of the freezing of USDT for $42.4 million, Thai businessmen Nutthawat Rukthammalalern and Natthawat Kasamvilas filed a lawsuit in the Southern District of New York, claiming that Tether had blacklisted them with Taifang wallets without a court authorization. According to the complaint, in October 2025 Tether restricted ten Taifung addresses, holding 42417785.62 USDT. According to the merchants, the freeze was the result of an unofficial request from an agent of the Homeland Security Investigation Service (HSI) and no notification was received prior to the loss of financial access. It also stated that Tether had acted without a court order. The freeze was linked to a suspected fraud investigation in North Carolina, where investigators claimed that the stolen USDT had been transferred through multiple wallets to conceal its origin. While business people admitted that the disputed funds were related to the proceeds of fraud, their litigation challenged Tether ' s power to restrict USDT in the secondary market without judicial authorization。
