Free and without sign-up: we compare the TRON address with the USDT blacklist in the Tether contract and with the OFAC SDN list. The result takes a couple of seconds.
“Clean” means the address is not on these lists at the time of the check. It is not AML risk scoring or a legal opinion.
USDT on this address is frozen: it cannot be transferred, and funds sent to it will be blocked as well. Do not accept or send USDT to this address.
Transactions with this address may violate sanctions requirements. Stop the deal and consult your compliance team.
This is not a TRON address. It must start with T and be 34 characters long.
Too many checks. Please try again a little later.
The check failed. Please try again later.
Turn on address monitoring — the sender is checked before you close the deal.
Tether keeps the list of blocked addresses right in the USDT smart contract on the TRON network. We read it from our own node and refresh it with every new block. We load the OFAC SDN list from the website of the US Treasury and compare every TRON crypto address in it.
It does not assess how “dirty” funds are along the chain of transfers and does not link an address to exchanges or mixers. That takes full AML scoring.

For now only the TRON network: TRX and USDT-TRC20.
Up to 20 checks per minute and 500 per day from one IP address. To check incoming transfers continuously, use monitoring or the API.
No. The address you check is not written to logs and is not stored. Limits are counted by a hash of the IP address that changes every day.
