USDT and USDC contract check
Fake tokens copy the name and symbol of USDT. The contract address is what tells them apart. Paste one to compare it with the list the issuer publishes.
The issuers' list is not loaded yet, so no contract can be checked right now. Nothing is shown instead of it — a list typed in here could be out of date.
A valid format does not mean the address belongs to the right person. It only means the address is well-formed. Compare the whole address with the source and send a small test amount first.
FAQ
How do I know if a USDT token is real?
Compare its contract address with the address the issuer publishes for that network. The name and symbol can be copied by anyone; the contract address cannot.
What does “not on the issuer's list” mean?
That the address is not one Tether or Circle publishes. A token at another address is a different token, whatever it is called.
Should I send USDT to the contract address?
No. The contract is the token's program. Coins or tokens sent to it are not credited to anyone.
