Which chain isthis address on?
Paste a wallet address. Find out what network it belongs to, whether it survives its own checksum, and whether we can pay it — before the money moves.
Paste an address above.
Nothing leaves this page. The check runs entirely in your browser — no address is sent to us or to anyone else, and nothing is stored. What it cannot tell you is who owns the address: only that it is well formed for a chain, and which one.
Why this goes wrong
Every chain's address looks like every other chain's address.
A string beginning 0x is valid on Ethereum, Polygon, BNB Chain, Arbitrum, Base and
a dozen more — the same forty characters, a different network. That is why "I sent USDT to the
wrong network" is one of the most common ways people lose money in this business: nothing about
the address told them which chain it was for, and the send screen did not stop them.
Same address, different chain
An 0x address exists on
every EVM chain at once. Sending to the right address on the wrong chain is the classic loss.
A checksum catches a typo
Mixed-case 0x addresses, Tron
addresses and TON addresses all carry a checksum. One wrong character and it fails — which this
page checks.
A token contract is not a wallet
People paste the USDT contract address instead of their own. It is a valid address; the money is simply gone.
What we pay
Two networks, deliberately.
TrueTransfer settles in USDC on Polygon and USDT on TON. Those are the two this
checker will tell you we can pay into. USDT on Tron was retired on 19 September 2026 and is
not coming back — if your payout address starts with T, set a different one before
your next sale rather than after it.
Everything else the checker recognises — Bitcoin, Solana, other EVM chains — it identifies so you know what you are holding. It does not mean we pay there.
Questions
Straight answers.
Can you tell me who owns an address?
No, and neither can anyone else from the address alone. A chain records balances and transfers, not names. This page tells you which network a string is valid on and whether its checksum holds — nothing about the person behind it. Treat any service claiming otherwise with suspicion.
I sent USDT to the wrong network. Can I get it back?
Sometimes, and it depends entirely on who controls the destination. If you sent to an exchange deposit address on the wrong chain, open a support ticket immediately — some exchanges recover these for a fee, some do not. If you sent to a wallet you control on another chain, import the same seed phrase into a wallet that supports that chain and it will be there. If you sent to an address nobody controls, it is gone. Nothing on this page can reverse a transfer.
Is my address sent to your servers?
No. The check is JavaScript running in your browser; there is no network request. You can disconnect from the internet after the page loads and it will still work. We would not paste a payout address into a site that did otherwise.
What does "checksum failed" mean?
The address is the right shape but at least one character is wrong — almost always a typo or a bad copy-paste. Mixed-case Ethereum addresses, Tron addresses and TON addresses all encode a check over their own contents, so a single changed character is detectable. Do not send to an address that fails this.
Why does an all-lowercase 0x address pass without a checksum?
Because lowercase Ethereum addresses are valid and carry no case information to check against. The EIP-55 checksum lives in the pattern of capital letters, so an address with none cannot be verified this way — only its length and character set. If you have a mixed-case version, use that one.
Does a valid address mean the payment will arrive?
It means the address is well formed for that chain. It does not prove the address is yours, that the wallet is set up, or that you chose the right network on the sending side. Send a small amount first when an address is new to you — that habit costs cents and has saved people a great deal.
