Why Is My USDT Frozen? What You Can Do

First: who froze it?

What you see	Who is holding it	Where to start
A deposit or withdrawal is on hold in your exchange account	The exchange. The coins on-chain may be fine.	Exchange froze your crypto
Transfers from your own wallet fail, and a freeze checker says the address is blacklisted	Tether, in the USDT contract itself	This guide
Transfers fail, but the address is not blacklisted	Probably nobody. Check that you picked the right network and have enough of its own coin (TRX or ETH) to pay the fee.	Your wallet’s help pages

To see the blacklist status, use a free checker or read the contract on a block explorer — see USDT freeze checkers compared. A freeze check needs only the address, never a wallet connection.

Why Tether freezes addresses

Tether’s terms let it freeze USDT where the law requires it “or where Tether, in its sole discretion, determines it is prudent to do so”, and list blacklisting an address as one of its remedies.^[1] In practice most freezes follow law-enforcement requests and US sanctions: Tether says it follows the US Treasury’s SDN sanctions list and can restrict USDT in wallets linked to illicit activity,^[2] and that it acts “when credible information is provided by law enforcement”.^[3]

What a freeze does on-chain

The USDT contract’s code is public. On Ethereum, only the contract owner — Tether — can add an address to the blacklist or remove it. A blacklisted address cannot send USDT: the transfer functions reject any sender on the list. The code does not stop other people sending USDT to the address, so new USDT that arrives there is stuck as well. Tether can also “destroy” the balance of a blacklisted address, which removes those tokens from the supply.^[4] The USDT contract on TRON has the same blacklist functions.^[5]

In US forfeiture cases, the frozen USDT can end up with the authorities. In one 2024 case in Ohio, Tether “burned” the frozen USDT under a federal seizure warrant and reissued the same amount to a wallet controlled by US law enforcement; prosecutors said notice of the case would be sent as a message on the blockchain to the frozen addresses.^[6] So watch your address for incoming messages.

What you can do

1. Confirm the status yourself on a block explorer or a free checker, for the network your USDT is on — the blacklists are separate for each network.
2. Contact Tether through the support site named in its terms. Under those terms, a formal dispute goes to confidential, binding individual arbitration.^[1]
3. Gather records of where the funds came from: exchange statements, P2P order IDs and chats, invoices.
4. For large amounts, or if you get a forfeiture notice, talk to a lawyer in your country.
5. Don’t expect a new wallet to help. The freeze is on the address; frozen USDT cannot be moved out of it.

Be realistic about the odds. The security firm BlockSec counted 4,163 USDT addresses blacklisted in 2025, holding $1.26 billion. Only 150 of them (3.6%) were removed from the list the same year, after a median of 18.2 days; $698 million of the frozen USDT (55.6%) was destroyed.^[7] These are a vendor’s figures, not Tether’s.

USDC works differently

Circle’s written policy is narrower. It says it will not deny access to individual addresses except in cases that strictly meet its policy — mainly network security threats, legal orders from US or French authorities, and sanctions — and that a blocked address can no longer send or receive USDC. It may reverse a block once the authority confirms the order has been lifted.^[8] Under its USDC terms, funds at a blocked address may lose their rights.^[9]

“Unfreeze” services are scams

If you were scammed, report it to the police and, in the US, to the FBI’s IC3. Don’t pay anyone who contacts you first.
