What is a Bitcoin TXID — and where to find yours
Support teams, block explorers and accelerators all ask for it. Here is what a transaction ID is, why it is safe to share, and exactly where each popular wallet and exchange hides it.
Short answer: open the transaction in your wallet or in your exchange's withdrawal history and look for a field called Transaction ID, TXID, Hash or a View on block explorer link. A Bitcoin TXID is always 64 characters long, using only the digits 0–9 and the letters a–f.
What a TXID is
Every Bitcoin transaction gets a unique identifier: a fingerprint calculated by hashing the transaction's data. Because it is derived from the content itself, nobody assigns it and no two different transactions share one. Think of it as the tracking number of a parcel — it tells you nothing secret, but anyone can use it to look up where the parcel is.
You will see it under several names, which all mean the same thing on Bitcoin:
- TXID or TxID
- Transaction ID
- Transaction hash, Tx hash or just Hash
Example of what one looks like: 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b (that one belongs to the very first Bitcoin transaction, in the genesis block).
| Don't confuse it with | How to tell the difference |
|---|---|
| A Bitcoin address | Starts with bc1, 1 or 3 and has 26–62 characters. It identifies where coins go, not a specific payment. |
| A block hash | Also 64 hex characters, but usually begins with a long run of zeros (000000000000…). |
| An exchange order or withdrawal ID | Short internal reference (often digits only). Block explorers can't find it. |
| An Ethereum/TRON tx hash | Ethereum hashes start with 0x. A Bitcoin explorer won't find transactions from another chain. |
Is it safe to share a TXID?
Yes. A TXID is public information: it is already visible to everyone on the blockchain. It does not reveal your private key, does not give access to your wallet, and nobody can move coins with it. The only thing it reveals is the transaction itself — amounts and addresses — which is public anyway.
What you must never share is your seed phrase (12 or 24 words) or a private key. Anyone asking for those while "helping" with a stuck transaction is trying to steal your funds. A legitimate accelerator or support agent only needs the TXID.
Find the TXID in your wallet
The idea is the same everywhere: open the coin's history, tap the transaction, look for the ID or an explorer link. Menu names change from version to version, so if a label below doesn't match exactly, look for the closest equivalent.
Exodus
Mobile: tap the Wallet icon, choose Bitcoin, scroll to the activity list and tap the transaction — the details include the transaction ID, which you can copy or open in a block explorer. Desktop: open the Bitcoin wallet and click the arrow next to the transaction to reveal its ID.
Trust Wallet
Tap Bitcoin in your wallet list, then tap the transaction. In the details screen choose View on block explorer (older versions call it More details); the explorer page shows the transaction hash at the top, ready to copy.
Ledger Live
Go to Accounts, open your Bitcoin account and click the transaction in its history. The details panel shows the transaction ID and a link to view it in an explorer.
Electrum and Sparrow
In Electrum, open the History tab and double-click the transaction; the window that opens shows the Transaction ID at the top. In Sparrow, open the Transactions tab and select the transaction — its ID appears in the transaction view.
Any other wallet
Look in the transaction's details for "ID", "Hash" or an explorer link. If your wallet only shows the receiving address, paste that address into a block explorer such as mempool.space: it lists every transaction to and from the address, each with its TXID.
Find the TXID on an exchange
For withdrawals, the TXID lives in your withdrawal or transaction history, not in the trade history.
| Exchange | Where to look |
|---|---|
| Binance | Website: Wallet → Overview → Transaction History, then the deposit or withdrawal; the TxID is in the details. App: Wallets → Spot → Transaction History and tap the entry. |
| Coinbase | Open the asset you sent, select the transaction and choose View transaction / View on block explorer to see and copy the hash. |
| OKX | Assets → History, choose the Withdrawal or Deposit tab, open Details. |
| Bybit | Assets → Funding Account → History → Withdraw, then Details. |
| Kraken and others | The deposit/withdrawal history entry shows the blockchain transaction ID once the transfer has been broadcast. |
If the exchange shows a TXID but your Bitcoin isn't arriving, our guide to pending exchange withdrawals explains each status and what to do.
No TXID yet? Here's why
- The withdrawal hasn't been broadcast yet. Exchanges batch and review withdrawals before sending them. Binance says a TxID is typically generated within 30–60 minutes, and asks you to contact support if it still isn't there 6 hours after you confirmed the withdrawal.
- It was an internal transfer. Moving coins between two accounts on the same exchange (for example Coinbase to Coinbase) usually happens off-chain. There is no blockchain transaction, so there is no TXID — only an internal reference.
- It was a Lightning payment. Lightning payments don't create an on-chain transaction each time; they have a payment hash instead, and on-chain accelerators can't help with them.
- The wallet never broadcast it. If the wallet shows "pending" but no explorer can find the TXID, the transaction may never have reached the network or may have been dropped from the mempool.
When your TXID changes (and why that's normal)
A TXID is tied to the exact contents of a transaction. If anything changes, so does the ID:
- Replace-by-Fee: when you bump the fee with RBF, your wallet creates a new transaction with a new TXID. The old ID will show "replaced" or disappear from explorers. Track the new one.
- Child-Pays-for-Parent: with CPFP the original TXID stays the same, but the child transaction you create has its own TXID.
- Premium acceleration doesn't touch the transaction at all, so the TXID stays identical from start to confirmation.
What to do with your TXID
- Check the status. Paste it into our free transaction status checker to see whether it is confirmed, its fee rate and its position in the mempool queue.
- Work out the wait. Compare its fee rate with the next-block rate — how long a Bitcoin transaction takes explains what the numbers mean.
- Speed it up if needed. Paste the TXID into the accelerator: free rebroadcast, or premium acceleration from $20 if the fee is too low and you can't use RBF or CPFP yourself.
- Send it to support. When a payment goes missing, the TXID is the single most useful thing to give the recipient's support team.
Frequently asked questions
How long is a Bitcoin transaction ID?
Always 64 hexadecimal characters: digits 0–9 and letters a–f. If what you have is shorter, longer, or contains other letters, it is an address, an exchange reference or a hash from another blockchain.
Can someone steal my bitcoin with my TXID?
No. A TXID is public and gives no control over any coins. Only a seed phrase or private key can move funds — never share those with anyone.
Why can't the block explorer find my TXID?
Either the transaction hasn't been broadcast yet (common with exchange withdrawals in the first hour), it was dropped from mempools, it was replaced by an RBF transaction with a new ID, or the ID belongs to another blockchain. Double-check that you copied all 64 characters.
Is the TXID the same as the transaction hash?
For Bitcoin, yes — wallets and explorers use "TXID", "transaction ID" and "transaction hash" interchangeably. (Technically SegWit transactions also have a separate "wtxid" that includes signature data, but wallets and explorers show you the TXID.)
Does accelerating a transaction change its TXID?
RBF creates a new transaction with a new TXID. CPFP and premium acceleration leave the original TXID unchanged.
