Check an address before you send USDT
Paste your counterparty's TRON address. In a few seconds we'll tell you whether it is sanctioned, whether its funds are frozen, and who it has been dealing with.
Five checks in a few seconds
What we look at for every address
Sanctions
Whether the address is on official sanctions lists — US (OFAC), EU, UK, UN and other countries — and any entity attribution recorded by those sources.
USDT freeze
Whether Tether has blacklisted the address. The report uses the USDT contract response for its snapshot; recent reports may be cached.
Connections
Who the address exchanged USDT with: any sanctioned or frozen wallets among its counterparties.
Service labels
Imported address and counterparty labels also affect the score. They are separate from official sanctions and are not independently verified.
Behaviour
Address age, pass-through patterns, address-poisoning attempts in the transfer history.
No sign-up and no waiting
How it works
1Paste the address
Copy the TRON address from your chat with the counterparty. We strip spaces and stray characters ourselves.
2Wait a few seconds
We match it against OFAC, query the USDT contract and read the transfer history.

The result at a glance
How to read the result
Low risk
No medium or high risk level within the checked scope. Minor warnings may remain; this is not a guarantee.
Medium risk
There are signs worth a look: a new address, pass-through transfers, questionable connections.
High risk
Sanctions, a freeze, or direct transfers with such addresses. Better not to proceed.

In short the essentials
Frequently asked questions
Where does the data come from?
Government sanctions lists of the US, EU, UK, UN and other countries (via OpenSanctions), the blacklist inside the USDT contract and the transfer history on the TRON blockchain, plus imported service labels that are separate from official sanctions.
Does “low risk” mean the address is definitely clean?
No. It means no medium or high risk level was found within the stated scope; minor warnings may remain. A scammer can use a fresh clean address. For a large amount, always start with a small test transfer.
Will the address owner know I checked it?
No. The check reads blockchain data and sends nothing to the address. Recent checks live in your browser; reports you explicitly save to your account are stored in Supabase.
What is a “USDT freeze”?
Tether, the issuer of USDT, can blacklist an address — usually at a law-enforcement request or because of fraud. USDT on such an address cannot be sent anywhere.
Why do I need the PDF report?
It is proof that you checked the counterparty before the deal: with a date, sources and a checksum. Attach it to your chat or show it to an exchange if questions arise.
