Tether blacklist: how to check an address

What a USDT freeze is, how to find out whether an address is on the list, and why links to frozen wallets matter more than the list itself.

The Tether blacklist is the set of addresses the USDT contract forbids from transferring. A freeze is a single addBlackList transaction from a Tether wallet; after it the USDT on the address cannot move: not sold, not withdrawn, not returned. On TRON there are more than 8,000 such addresses and the list grows every week. Unfreezes are rare and require a court order or a law-enforcement request.

How to check an address against the Tether blacklist

Way 1

In the bot, 10 seconds

Send the address to @freezecheck_bot. A frozen address gets the “frozen by Tether” label with the date and a link to the freeze transaction. The bot also shows whether the address is linked to other frozen wallets, which matters more than the freeze itself.

Way 2

On Tronscan by hand

Open the USDT contract TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t, tab Contract → Read → getBlackListStatus, paste the address. “true” means frozen. You only see the address itself, not its links.

Way 3

As a list

For exchangers: a .txt / .csv file with up to 50 addresses sent to the bot returns a table and a CSV of verdicts. The “Watch” button under a report warns you if the address gets frozen later.

Why “not on the list” does not mean “safe”

Tether freezes with a delay: days, sometimes weeks pass between a transfer and the freeze. A wallet that is clean by the list today may be on it tomorrow, and the USDT of everyone who accepted money from it gets frozen along with it. That is why FreezeCheck looks not only at the list but at three things around it.

Direct transfers with frozen addresses. Whether the wallet received USDT from anyone on the blacklist or sent there, when and how much.
The chain up to five hops. Money may have passed through an exchanger or a pass-through wallet. The bot names the intermediaries in words and shows the share of dirty funds.
The freeze pattern. A model trained on thousands of real freezes estimates whether the wallet behaves like those already frozen. On freezes that happened after training it flagged 84 out of 100 in advance in a blind test.

Whom Tether freezes

On requests from law enforcement (US, EU, Israel, Asian countries), from Tether's own investigations and from exchanges: hackers, drainers, fraudulent “investment” platforms, wallets of sanctioned organisations and those who accepted large sums from them. Most often the victim is not the organiser of the scheme but whoever took the money last: an exchanger, a P2P seller, a shop.

If your own address was frozen, read USDT frozen: what to do: the order of actions, the Tether request form and what not to do.

Questions and answers

How many addresses are on the Tether blacklist on TRON?

More than 8,000 as of November 2026, and the list grows every week. All of them are labelled in FreezeCheck with the freeze date.

Can a freeze be lifted?

Only through Tether: a request with documents, usually together with a court order or a law-enforcement request. Unfreezes are rare; there is no way to bypass the blacklist.

Is the blacklist check free?

Yes, 3 checks a day in the bot with no sign-up, with the full report, graph and PDF. A pack of 10 checks — ~~$2.99~~ free, limited time only.

What if the counterparty's address is linked to a frozen one?

Look at the details in the report: one small transfer a year ago and hundreds of thousands of USDT directly are different situations, and the bot scores them differently. On 🔴 do not accept the money; on 🟡 ask where the funds come from.

Can I get a warning if the address is frozen later?

Yes. Tap “Watch” under the report: the bot messages you if the address lands on the Tether blacklist or a sanctions list.
