Tron USDT blacklist check
Most USDT moves on TRON as TRC-20, and Tether freezes more addresses there than anywhere else. This Tron USDT blacklist check asks the official USDT contract on TRON (TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t) whether an address is blacklisted: a live isBlackListed(address) read, not a cached label. Sanctions list data is shown alongside. If our TronGrid access is not configured the result says unavailable, never "not frozen".
How a USDT freeze works on TRON
The TRC-20 USDT contract carries a blacklist that only Tether can edit. Once an address is added, any transfer sent from it is rejected: the balance stays visible on the explorer, but it cannot move. Tether adds addresses at the request of law enforcement and on its own investigations. The same mechanism exists on Ethereum and Avalanche, but the bulk of freezes happen on TRON because that is where the volume is.
The read is a constant call: isBlackListed(address) returns true or false, so the answer is the contract's own state at the moment you asked, not a list somebody compiled earlier. A result can change minutes later; this tool does not store your query, so re-check before you act.
A freeze is not a sanctions listing
An issuer freeze and a sanctions designation are two different facts from two different sources. A frozen address is not thereby on OFAC, UK or EU lists, and most addresses on those lists have never been frozen, because Tether only freezes what it is asked to. Treat "frozen" as a strong signal your compliance file should be able to explain. "Not frozen" is not clearance. For the listing question, run the wallet sanctions check; for USDT on Ethereum and Avalanche, the use the USDT blacklist check.
KYTGate records the freeze status at the moment of each deposit and withdrawal inside a signed Decision Receipt, so the state you acted on can be proven later even if the address is frozen afterwards. What that means for a broker's settlement and payout flow is on stablecoin compliance for brokers.
USDT addresses frozen right now, by chain
Addresses whose latest event on the contract is a freeze, read from the contracts' own blacklist events. “≥” means that contract's history is still being read. Coverage per contract is on the stablecoin freeze tracker.
Questions people ask
A TRON address starts with T and is 34 characters of base58 with a built-in checksum. Unlike Ethereum hex, it is case-sensitive: changing one letter's case makes it a different, usually invalid, address. The check rejects anything that fails the checksum instead of guessing what was meant.
Same issuer, separate contracts and separate blacklists. Tether freezes per contract, so an address frozen on TRON is not automatically frozen anywhere else, and the same person's Ethereum address is a different address altogether. Check the network the funds actually moved on.
Because most USDT transfers happen there: low fees made TRC-20 the default rail for exchanges, OTC desks and payment flows, including illicit ones. The freeze counts below are read from the TRON contract's own blacklist events, so you can see the scale for yourself.
No. Only the official Tether contract TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t carries Tether's blacklist on TRON. Any other token calling itself USDT is not Tether's token, has no Tether freeze, and should not be credited as USDT.
