USDT blocked: frozen address or a held exchange deposit

How to tell what happened

The address is frozen by the issuer if:

• the USDT shows on the balance, but any transfer from the address is rejected;
• it is your own wallet, not an exchange account.

The exchange is holding the deposit if:

• you sent USDT to an exchange, the transfer went through on the blockchain, but the amount did not appear in your account or is marked “under review”;
• support mentions an AML check or source of funds, or asks for documents.

If you cannot send from your own wallet and the address is not frozen, the cause may be energy or permissions, see why USDT will not send.

If the issuer froze the address

The USDT issuer can freeze an address in its contract. After that, the USDT on that address can be neither sent nor spent. This usually happens at the request of law enforcement or after theft reports.

You can check an address for free in the GuardPay /usdt-banned freeze list: it is built from freeze events on the blockchain and shows the date.

What to do:

• If the address is yours and you do not know why — write to the issuer through its official website with an explanation of the source of funds and your deal history. Do not pay anyone who promises to “unfreeze it for a fee”.
• If you received USDT from someone whose address was later frozen — your funds are not frozen by that, but check where the money came from before depositing it on an exchange.
• If the scammer’s address that received your money was frozen — that is good news: the funds stay put. Give the police case number so it is taken into account for a return.

If the exchange is holding the deposit for review

Exchanges screen incoming deposits. If the money passed through addresses linked to thefts, sanctions or risky services, the deposit may be held and you may be asked to explain. Often this is not about your actions but about the money’s history a few transfers before you.

GuardPay /frozen-deposit takes the transaction hash, checks the sender, shows where the money came from and drafts a letter to the exchange’s compliance team.

What to include in your reply to the exchange:

• where you got the USDT: a purchase, a sale, payment for a service — with date and amount;
• the chat or contract with the sender;
• a statement or screenshot if you bought the USDT on another exchange;
• the deposit transaction hash.

How to avoid this next time

• Check the payer’s address before a deal, especially when selling USDT to strangers, see how to check an address.
• Do not deposit money from strangers on an exchange without checking where it came from.
• Keep chats and deal details: you will need them if asked about the source of funds.
