Tether (USDT) Blacklist Address Checker
An instant query to the USDT smart contract on TRON, Ethereum and Solana: we ask the contract itself whether the issuer has blocked the address (on Solana, whether it is frozen through the freeze authority). That is the primary source, the same contract that physically blocks transfers. Free, no registration.
The same check right in Telegram: send an address to the bot and get the verdict in 2 seconds. Handy before every P2P deal.
Open the botHow this check works
- You enter a TRON (T…), Ethereum (0x…) or Solana address; the network is detected automatically.
- The server makes a direct call to the USDT smart contract's blacklist function via public blockchain nodes. No intermediaries, no databases.
- The contract's answer is binary: the address either is on the issuer's blacklist or is not. A primary-source fact, not an estimate.
Frequently asked questions
How is this different from an AML check?
AML services compute a probabilistic risk score over the transaction graph. Our checker asks the USDT contract itself whether the issuer blocked the address. A binary fact. A clean answer here does not guarantee a low risk score on an exchange; those are different control layers.
The address is blacklisted. Are the funds lost forever?
Not necessarily. Tether lifts restrictions through a legal procedure upon documented non-involvement: a forensic report, an affidavit and a Source of Funds. Months of work with no guarantees, but the path exists. See the USDT restriction guide.
Do you store the addresses I check?
Yes, anonymously (address, network, result, time), for aggregated freeze statistics. Blockchain addresses are public anyway; the checker collects no personal data.
