Legal proceedings have emerged after two Thai businessmen initiated a challenge against a $42.4 million USDT freeze. Nutthawat Rukthammachalern and Natthawat Kasamvilas filed their complaint in the Southern District of New York, alleging that Tether added their ETH as its native asset.">Ethereum wallets to a blacklist before any court issued an official warrant.
As detailed in the court filing, Tether restricted ten ETH as its native asset.">Ethereum addresses during late October 2025. These wallets contained a combined total of 42,417,785.62 USDT belonging to the two individuals. The businessmen assert that an informal directive from a Homeland Security Investigations (HSI) agent prompted the restriction, and they report receiving no prior warning before losing access to their assets.
Tether News Focuses on Freeze Before Court Warrant
Kasamvilas reportedly uncovered the restriction only after attempting to transfer his USDT holdings. He subsequently reached out to Tether to gather details regarding the frozen stablecoin balances.
The lawsuit states that Tether pointed him toward an HSI email address. The plaintiffs maintain that no judicial order or warrant was in place when the blacklist was initially enforced.
This Tether USDT freeze tied back to an active North Carolina investigation concerning suspected pig-butchering scams. HSI Raleigh initiated the inquiry after receiving a victim’s report detailing romance and investment fraud.
Investigators claimed that illicitly obtained USDT bounced through multiple addresses to obscure its source. One wallet linked to a plaintiff allegedly held approximately $26.1 million during the course of the investigation.
That specific address was reportedly mapped as a consolidation hub within the alleged money laundering path. Nonetheless, the plaintiffs are not attempting to halt the ongoing government investigation. Instead, their lawsuit challenges Tether’s legal standing to restrict secondary-market USDT holdings prior to obtaining judicial clearance.
February Warrant Ordered USDT Burn and Reissue
A federal court located in North Carolina issued a formal seizure warrant on February 19, 2026. This directive instructed Tether to destroy the frozen USDT tokens and mint equivalent replacements, which were then routed to a government-operated wallet. Five days afterward, officials publicized a wider seizure valued at over $61 million in USDT.
Authorities connected this larger seizure to addresses purportedly utilized for laundering funds extracted from pig-butchering victims.
Representatives publicly expressed gratitude toward Tether for facilitating the transfer. While the Thai businessmen do not dispute that authorities claim the funds stem from fraudulent activities, their lawsuit takes issue with Tether’s actions both before and after the warrant was issued.
The plaintiffs contend that the February warrant cannot retroactively legitimize the October blacklist. They further question whether the order genuinely gave Tether the right to burn and reissue their stablecoins.
According to their legal filing, they acquired the USDT through normal business operations and were not direct customers of Tether.
Tether Update: Plaintiffs Seek Unfreezing, Damages and Reserve Yield
The lawsuit urges the court to block Tether from destroying the disputed tokens. It additionally demands an injunction forcing Tether to lift the wallet blacklist, along with financial damages if the USDT has already been permanently eradicated.
The claims brought forth in the lawsuit include conversion, trespass to goods, unjust enrichment, and requests for judicial relief. The unjust enrichment claim specifically targets revenue generated from the financial reserves backing the frozen USDT.
The plaintiffs argue that Tether continued to generate DAO controls and spends.">Treasury-backed yields while they remained barred from accessing their assets. Consequently, they want the court to mandate a full refund of that contested income.
