Fake USDT: how to tell real Tether from a look-alike token

How a fake token passes for USDT

MetaMask describes the pattern: a scammer’s token imitates a common token’s symbol, such as USDT or ETH, but is a different token with no real value. Because MetaMask and other wallets use the symbol to look up price information, the value of the real token may be displayed under the fake one — so a worthless balance can appear to be worth exactly what the same amount of USDT would be (MetaMask Help Center).

The scam around it, as MetaMask lays it out, is slow. Trust is built over time, then the victim is guided to add custom networks and tokens to the wallet, to send real funds, and to watch a balance of fake tokens that shows a value it does not have — and that cannot be withdrawn.

The name proves nothing

A token contract publishes its own name and symbol, and whoever deploys it chooses them. That is why asking a contract what it is called, however useful for checking decimals, cannot tell you whether it is genuine: a copy can answer “Tether USD” too. MetaMask’s advice is to learn how to check whether a token contract is trustworthy using a block explorer, and to be very careful about adding unverified custom networks (MetaMask Help Center).

The addresses Tether publishes

The reference for what is genuine is the issuer. On its supported protocols page, Tether lists these USD₮ contracts (Tether):

• Ethereum: 0xdac17f958d2ee523a2206206994597c13d831ec7
• TRON: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t
• Solana: Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB

For BNB Smart Chain and Polygon, the page as we read it does not list a USD₮ address. Our guides for those networks name the contracts that circulate there and what those contracts report when asked — on BNB Smart Chain and on Polygon, where it calls itself USDT0 — and say plainly that this is not a confirmation from the issuer.

To use the list, open the token in your wallet or on a block explorer, find its contract address and compare it with the one Tether publishes for that network — every character, including the middle, not just the start and the end. That is the same check MetaMask asks for before sending to any address, for the same reason: a copy only has to look right where people glance (MetaMask Help Center).

Two warning signs

Neither needs any technical check. The first is being told, by someone you met online, to add a custom network or token so that a balance appears. The second is unsolicited contact offering an investment opportunity. MetaMask names both, and adds that if anyone walks you through specific steps in MetaMask, you should contact MetaMask Support before following them (MetaMask Help Center).
