Tether (USDT) Blacklist Address Checker
An instant query to the USDT smart contract on TRON, Ethereum and Solana: is the address blocked by the issuer (on Solana, frozen via the freeze authority). This 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.
