What is a transaction hash (TXID), and how do you find it?
A transaction hash, also called a TXID, is the unique identifier of a single cryptocurrency transaction, a long string of letters and numbers that permanently records that transfer on the blockchain. You find it in your wallet or exchange transaction history, or by searching an address on a blockchain explorer. It lets anyone look up the amount, the sending and receiving addresses, the time, and whether the transfer confirmed. It is safe to share, and it is the single most useful piece of information in any scam report or support request.
The short definition
A transaction hash (TXID) is the fingerprint of one crypto transaction. Every transfer that settles on a blockchain is given a unique string, and that string is how the transaction is found and referenced forever after. If a wallet address is like a bank account number, a TXID is like the reference number of a single payment into or out of it.
You will be asked for it constantly, by exchange support, by anyone helping you report a scam, by a blockchain tracer, so it helps to know exactly what it is, where it lives, and what it can and cannot tell you.
What a TXID can, and cannot, show
Looked up on a blockchain explorer, a TXID reveals the public facts of a transfer. It does not reveal the private facts behind it.
What it shows: the amount sent, the sending and receiving addresses, the network, the date and time, the fee, and the confirmation status. What it does not show: the real-world identity of either party. An address is not a name. This distinction matters enormously in fraud cases, where people often assume a TXID can "reveal the scammer," when in fact it reveals the scammer's address, which is a different and much harder thing to connect to a person. Our guide to how blockchain tracing works covers that gap.
Where to find your TXID
The location depends on where the transaction happened.
| Where the transfer happened | Where to find the TXID |
|---|---|
| A crypto exchange | Transaction or withdrawal history, often under the specific transaction's details |
| A software or hardware wallet | The transaction's details in your activity or history list |
| A blockchain explorer | Search your address, then open the specific transaction |
On many exchanges the TXID appears only when you expand a transaction's full details, sometimes labelled "TxID", "Transaction ID", or "Transaction Hash". It is usually accompanied by a link straight to a blockchain explorer, which is the public page for that transaction.
Why the network matters
The same asset can exist on different networks, and a TXID is specific to one of them. A USDT transfer on Ethereum and a USDT transfer on Tron produce TXIDs that live on different blockchains and must be looked up on different explorers. When you record or share a TXID, note the network too, or it cannot be found. This is also why a TXID is central to resolving a wrong-network transfer.
TXID versus address versus memo
Three identifiers are easy to confuse:
- A TXID identifies one transaction.
- A wallet address identifies an account that can send and receive many transactions.
- A memo or tag is an extra routing label some networks require on a deposit.
A support request or report usually needs the TXID and the relevant addresses; a memo matters mainly for deposits to certain exchanges and chains.
How to share a TXID safely
A TXID is public information. Sharing it does not expose your funds, give anyone control of your wallet, or let anyone steal from you. It only lets them look up a transaction that is already public. So it is safe, and expected, to include it in a report to IC3, a ticket to an exchange, or a case with a tracer.
What is never safe to share is your seed phrase, private key, or password. Those control your wallet. Anyone who asks for them while "needing" your TXID is trying to steal from you. The TXID is fine; the keys are not.
In practice
When something goes wrong, the first thing to capture is the TXID and its network, because almost every next step needs it. Copy it from your wallet or exchange history, note the network, and save the blockchain-explorer link. Keep it with the rest of your records using our evidence checklist. With the TXID in hand, you can file a report, open a support ticket, or follow the transfer on an explorer yourself.
What this guide cannot do
Knowing your TXID does not, by itself, recover funds or identify who received them; it is the key that lets other processes begin, not the outcome. What it does is make every one of those processes faster and more credible, which is why it is the first thing to find and the last thing you should ever confuse with your private keys.
This is general information, not financial or technical advice.

Frequently asked questions
Is a transaction hash the same as a wallet address?
No. A transaction hash (TXID) identifies one specific transaction, while a wallet address identifies an account that can send and receive many transactions. Think of the address as an account number and the TXID as the reference number of a single payment to or from it.
Can someone steal my crypto with my transaction hash?
No. A TXID is public information that only lets someone look up a transaction that is already recorded on the blockchain. It gives no control over your wallet and no ability to take your funds. What you must never share is your seed phrase, private key, or password, which do control your wallet.
What if my transaction does not seem to have a TXID?
A settled on-chain transfer always has one; you may just need to expand the transaction's full details in your wallet or exchange, where it may be labelled TxID or Transaction Hash. If a transfer happened entirely inside one platform (an internal transfer), it may have an internal reference instead of an on-chain TXID.
Can I track a transaction with a TXID?
Yes, you can look up the public details, the amount, addresses, time, network, and confirmation status, by pasting the TXID into the right blockchain explorer for that network. What you cannot do with it alone is identify the real person behind an address, which is a separate and much harder step.
Why do I need to note the network along with the TXID?
Because the same asset can exist on several networks, and a TXID only exists on the one network where the transfer happened. A USDT transfer on Ethereum and one on Tron are looked up on different explorers. Without the network, the TXID often cannot be found.
