Why any list of fake crypto exchanges goes out of date

A site that looks like a real exchange today can reopen under a different domain next week, so a fixed list of fake crypto exchanges is already behind by the time you read it. It makes no difference whether the site says it is based in the United States or anywhere else, because that claim is only text on the page. The token behind the deposit stays the same. Genuine USDT runs on exactly one contract per network, and comparing that contract with the transfer you received tells you more than a list of names.

The two addresses that don't change when the exchange does

Tether publishes one contract for USDT on each network: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t on TRON and 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum. A token that calls itself USDT from any other contract is not Tether's USDT, whatever the exchange's interface says your balance is. An exchange can change its domain, its logo and its name. It cannot change which contract moves the token, because Tether sets that address.

A lookalike contract, in a made-up example

Made-up example: a copied deposit page lists a contract address that is almost identical to Tether's real one, with a couple of characters swapped in the middle. A deposit made with that lookalike contract is not real USDT. USDT on Ethereum follows a token standard called ERC-20, and USDT on TRON follows TRC-20. Under both standards, each token contract keeps its own ledger with one balance per address, and a transfer only adds to the balance in the exact contract it came from. A lookalike transfer raises your balance in the lookalike's ledger and leaves your balance in Tether's contract as it was. The exchange's page can display any number it likes. The balance that counts is the one Tether's contract records for your address.

A fake exchange and a fake token are different checks

A fake exchange is a platform: the website, the account dashboard and the login page, built to look like a trading venue. A fake token is a contract, a lookalike pretending to be USDT or another asset. You can run into one without the other. A real exchange can be tricked into listing a lookalike contract. A fake platform can also show you a genuine USDT transfer, because that transfer runs through Tether's contract and the platform has no say over it. A real deposit therefore does not prove that the platform is real.

Checking the platform means asking whether the site's domain and behaviour hold up, and TrustSniffer's website checker looks at exactly that. Checking the deposit means asking whether the transfer you received came from Tether's contract. Use the wallet checker and a blockchain explorer for that. Run both checks, because each one leaves the other risk untested.

Four fields Etherscan and Tronscan show for every transfer

Etherscan covers Ethereum and Tronscan covers TRON. Both read data straight from the blockchain, so a fake front end can't edit what they show. Use the explorer for the network the exchange says your deposit used. Search either your deposit address or the transaction hash, which is the unique ID of that one transfer. Then read the four fields below.

Each field should match something you already know. The sender should be an address you recognise. The recipient should be the deposit address the exchange gave you. The token contract should be Tether's address for that network, and the amount and time should agree with the dashboard. If all four match, the deposit is genuine USDT and the dashboard is accurate about that one transfer. If any field differs, stop and don't send the site more money. A clean match only confirms this one deposit. It doesn't show that the exchange will let you withdraw, so before you deposit anything else, try withdrawing a small amount and run the site through the website checker.

  • Sender: the address the funds actually came from.
  • Recipient: the address that received the transfer, so you can compare it against the deposit address the exchange gave you.
  • Token contract: match it against Tether's published address for that network. A different contract isn't USDT.
  • Amount and time: compare both against what the exchange's dashboard claims you deposited.

Frequently asked questions

If the contract matches, does that mean the deposit is correct?

A matching contract only confirms the token is genuine USDT. It doesn't confirm the amount. Compare the amount and time Etherscan or Tronscan show against what the exchange's dashboard claims, since a genuine token can still be sent in the wrong amount or at a different time than advertised.

Why not just publish a list of fake exchange names?

A name and a domain can change the day after a list is published. The network and contract behind a genuine USDT transfer are set by the issuer, so a contract check still works when a list of names is already out of date.
