Crypto address sanctions & USDT blacklist check

Paste an address to see right away whether it is on the OFAC sanctions list and whether Tether has blacklisted it in the USDT contract (TRON and Ethereum).

Two open sources

OFAC sanctions list

The US Treasury SDN list names the crypto addresses of sanctioned parties across BTC, ETH, USDT, TRX and other networks. We load it every day.

Tether blacklist

Tether can blacklist an address in the USDT contract, and the tokens on it stop moving. We collect every blacklist and unblacklist event on TRON and Ethereum and refresh the list daily.

FAQ

How do I check a crypto address for sanctions?

Paste the address into the form above. We match it against the US Treasury SDN list (OFAC), which names the crypto addresses of sanctioned parties, and show the party, the sanctions program and the listing date if it is found.

How do I know if USDT on an address is blacklisted?

The same form shows whether Tether has blacklisted the address in the USDT contract on TRON or Ethereum. A blacklisted address cannot send USDT until Tether lifts the block.

If the address is not on the lists, is it clean?

No. The lists only catch direct matches. If the funds came through several transfers from a mixer, scam or hack, the address won't be listed, yet an exchange may still freeze it. Only a full AML check shows that.

Do you store the addresses I check?

No. The address is only used to answer: we don't store it or link it to you.

How often is the data updated?

Both the OFAC list and the Tether blacklist are refreshed once a day. The last update date is shown in the result.
