Why does Tether freeze wallets? The multi-signature process explained

Tether (USDT) and Circle (USDC) can freeze any wallet that holds their tokens. They don't need your permission, and there is no appeal button. Here is who decides, how it works on-chain, and how often it happens.

Who decides

The issuer. Tether controls the USDT contracts; Circle controls USDC. Both contracts contain a blacklist that only the issuer can change.

Neither company publishes a reason for each freeze. Their terms let them freeze an address to comply with law-enforcement requests and sanctions, and to stop funds linked to hacks, scams and theft. A freeze is a decision by a company about its own token. It is not the same as a government sanction, though a sanction often leads to one.

How a Tether freeze works on-chain

On TRON and Ethereum, Tether's blacklist is controlled by a multi-signature wallet: several signers, and a freeze needs a set number of them to agree.

1. The proposal. One signer submits the freeze. It sits on-chain, waiting, and anyone can see it. That submission is the first signature.
2. The confirmations. Other signers approve it. On TRON it takes 2 signatures in all; on Ethereum, 3. When the last one lands, the contract starts refusing every transfer out of the wallet.

The gap between proposal and freeze is usually short. Across 2,113 TRON freezes we measured, the median was 7 minutes, and 25% were complete within a minute. A median is not a promise.

Circle's USDC is different. It freezes from a single address in one step, so there is no public proposal. A USDC freeze can only be seen after it lands.

What happens to a frozen wallet

• The balance stays visible and stops moving.
• The wallet can still receive, and anything sent to it is stuck too.
• Tether can later destroy the balance. It burns the frozen USDT and can issue the same amount again elsewhere. 2,346 addresses in our records reached that state.
• Tether can release it, through the same multi-signature process. 1,376 of 12,728 blacklisted addresses (11%) were released.

How often it happens

Year	Wallets frozen
2022	686
2023	766
2024	2,030
2025	4,332
2026 (to 25 October)	4,602

In 2026 so far, 3,669 of those freezes were USDT on TRON, 516 USDT on Ethereum and 417 USDC on Ethereum. The busiest month was March, with 985 wallets frozen. Every freeze is listed day by day, with its on-chain record, in our freeze reports.

Counted from the Tether and Circle contracts on TRON and Ethereum. A wallet frozen by both issuers counts once per issuer.

Freezes come in batches

Of 779,678 wallets that dealt with a wallet before it was frozen, 1,349 were frozen afterwards. The median gap was 123 seconds, and 65% happened within an hour. Tether freezes groups of related wallets at once, not one by one over months. This is a population figure, not a prediction about any wallet.

What this means for you

• Check who pays you before you accept. See How to check a wallet before an OTC or P2P trade.
• If you are already frozen, see Tether froze my USDT. What do I do now?
• Nobody can unfreeze a wallet for a fee. The refusal is written into the contract.
