Cross-border payments platform Conduit Technology has filed suit against stablecoin issuer Tether, alleging that Tether froze $2.76 million in USDt (USDT) in September 2025 without explanation.
In a complaint filed Monday in the US District Court for the Southern District of New York, Conduit said Tether froze funds belonging to the company even though it had "no legal entitlement" to them and "no claim" over them. Conduit said it began holding USDt in its digital treasury wallet in May 2025, and alleged that Tether froze the full $2.76 million in September with "no justification," an action the company said "materially impacted its business."
Conduit says the funds belong to the company
"The funds are unequivocally Conduit’s, but Tether has taken them and is denying Conduit access to them," the complaint said.
It added: "Tether is not allowed to take money from businesses just because they chose to store that money in Tether’s currency."
Freeze tied to a 2024 Brazilian investigation
According to the lawsuit, the freeze was connected to a Brazilian federal police investigation opened in 2024 into financial intermediary Bull Intermediação de Negócios and Onix. Conduit alleged that Tether, acting on its own initiative and using its own criteria, identified Conduit’s treasury wallet as tied to those companies and froze the $2.76 million on Sept. 24, 2025.
Conduit said it repeatedly asked Tether to release the funds, but that had not happened as of Monday. Cointelegraph said it reached out to Tether for comment on the lawsuit and did not receive an immediate response.
Another Tether freeze case was filed about a month earlier
The suit comes about a month after two Thai nationals sued Tether, alleging that the company froze $42.4 million in USDt after what they described as an "informal request" from US Homeland Security Investigations.
Those funds were allegedly part of a $61 million pig butchering case filed in the US District Court for the Eastern District of North Carolina. That court issued a seizure warrant for the USDt in February.
