USDT & USDC Contract Checker
Paste a contract address, mint, jetton or asset ID. We match it against the issuer-published list of every official USDT and USDC contract on 50+ chains, and for Tron and Ethereum we read the contract live so you can see what the chain says it is.
▸ 이 제품은 누구를 위한 것인가요?
Anyone about to add USDT or USDC to a wallet, accept it in a P2P trade, or integrate it in code, and who wants to know in three seconds whether the address in front of them is the one Tether or Circle actually issues. There are tens of thousands of tokens named USDT. One per chain is real.
▸ 제공되는 내용
A green, amber or red verdict. The chain, standard, decimals and issuer status for every match. An explorer link. And for Tron and Ethereum, the contract's own name, symbol and decimals read live from the chain so you are not taking our word for it.
USDT & USDC Contract Checker
USDT · USDC · 70+ CHAINS
Checked in your browser against the issuer-published list. Tron and Ethereum contracts are also read live from the chain.

▸ HOW TO READ THE VERDICT
OFFICIAL CONTRACT. Published by Tether or Circle on that chain. Native issuance or USDT0. Add it with confidence, then confirm on the explorer out of habit.
NOT AN ISSUER CONTRACT. Real and widely used, but issued by someone else: Binance-Peg on BNB Chain, a bridge (USDC.e), or a chain the issuer has left (USDC on Tron). Fine to use if you understand whose liability it is.
NOT ON THE OFFICIAL LIST. Valid format, no issuer behind it. A wallet, a different token, or a look-alike. Never add it as USDT or USDC.
NOT A CONTRACT ADDRESS. The text does not match any address format we recognise. Usually a paste with a missing character.

Frequently Asked Questions
What does this tool check?
It compares the address you paste against the list of USDT and USDC contracts that Tether and Circle publish on their own pages, mirrored on our reference post and updated when either issuer adds or drops a chain. A match tells you the chain, token standard, decimals and status (native, USDT0, Binance-Peg, bridged or discontinued) and links to the block explorer. For Tron and Ethereum addresses it also calls the chain directly and shows the contract's own name, symbol and decimals, and on Tron the deployer address.
Is my address sent to your server?
No. The official list is built into the page and the comparison runs in your browser. The live reads for Tron and Ethereum go from your browser straight to a public node (TronGrid and Cloudflare's Ethereum gateway). We never see what you paste.
What does "Not an issuer contract" mean?
The address is on our list, but the token at that address is not issued by Tether or Circle. The common cases are Binance-Peg USDT and USDC on BNB Chain (issued by Binance, 18 decimals), bridged USDC.e on Arbitrum, Polygon and Optimism (issued by a bridge contract), and USDC on Tron, which Circle stopped supporting in 2024. They are real and widely used; they are just a different liability from the issuer's own token.
What does "Not on the official list" mean?
The address is correctly formatted but no issuer publishes a USDT or USDC contract at it. It could be a wallet address pasted by mistake, a legitimate token that is not USDT or USDC, or a copy deployed to look like one. If a token with that address appeared in your wallet unasked, it is the third kind. Do not interact with it.
Why does the same 0x address show several chains?
Because USDT0, Tether's omnichain token, is deployed at the same address on several EVM chains, and Circle sometimes does the same. The tool lists every chain where that address is official. Check that the network you are actually on is one of them; an identical address on a chain not in the list is a different contract.
Can I use this to check a wallet address before sending?
Not for that purpose. This tool answers "is this token contract real?". For "is this wallet safe to send to?" use our guide to verifying a Tron address, and for "has this wallet been frozen?" use the blacklist check guide. All three are linked below.
Which chains are covered?
Every chain where Tether or Circle publishes a native contract: 13 for USDT and 38 for USDC, plus USDT0 deployments, Binance-Peg tokens on BNB Chain, bridged USDC.e on the main layer-2s, bridged USDT on Base, Optimism, Gnosis, Linea, Scroll and Sui, and the legacy chains the issuers no longer support (Omni, EOS, Algorand for USDT; Tron for USDC). The live contract read works on Tron and Ethereum mainnet.
The live read shows a different name from your list. Which is right?
The chain. Our list is a copy of the issuers' pages and can lag a rename; the chain is the source. If the live name and symbol look nothing like USDT or USDC for an address we mark official, tell us and we will check the row the same day.
