Tether froze $514 million worth of USDT across Ethereum and Tron this month, blacklisting 370 addresses. The move, confirmed by the company on May 10, 2026, is the largest single freeze action by Tether in 2026. It targets wallets tied to suspected illicit activity, though the company did not specify which investigation or jurisdiction prompted the action.
The scale of the freeze
This isn't a small sweep. $514 million is a significant chunk of USDT's total circulation. Tether said it added 370 addresses to its blacklist, effectively locking those funds. The company has frozen assets before, but the sheer number of addresses and the dollar amount make this one stand out.
Where the funds were stuck
The freeze hit both Ethereum and Tron, the two main chains where USDT lives. Tether didn't break down how much was on each network. But the fact that it covered both chains suggests the target was a broad operation, not a single exchange or wallet.
Why Tether keeps doing this
Tether has a long-standing policy of cooperating with law enforcement. It's frozen funds in the past after hacks, sanctions, or fraud investigations. The company says it works with global agencies, though it rarely names them. This time, it's likely no different — just bigger. The timing isn't great for Tether, which has faced scrutiny over reserves and transparency. A freeze of this size might quiet some critics who argue the company doesn't do enough to police its network.
What happens to the frozen USDT
The funds stay locked until Tether or authorities decide otherwise. In past cases, some frozen assets were eventually returned to victims. Others sat indefinitely. The 370 blacklisted addresses can't move a dime until the freeze is lifted. For now, the company isn't saying when that might happen — or if it ever will.
