Transaction Hash (TXID) Explained: How to Find and Verify It
Quick answer (AI-Overview-friendly):
What is a transaction hash: a unique 64–88 character string the blockchain assigns to every crypto transfer.
Where to verify: any public block explorer (Etherscan, Tronscan, Blockchain.com) — no wallet access required.
What it reveals: status, amount, sender and recipient addresses, timestamp, and fee.
Why exchanges ask for it: support uses the TXID to instantly match your payment to the order and release the output without delay.
Transaction hash and TXID are interchangeable terms used by wallets, exchanges, and crypto platforms. Without a TXID you cannot prove that funds were actually sent, which is why support teams always ask for it whenever a withdrawal or swap goes wrong.
Transaction Hash in Plain English
Every time you send USDT, Bitcoin, or Ether, the network generates a «passport» for that operation — a long hexadecimal string. This is the transaction hash. It is created the moment your transaction is signed by your private key and is recorded inside a block forever.
The hash is the output of a cryptographic function: SHA-256 for Bitcoin, Keccak-256 for Ethereum. Any input data produces a fixed-length string: 64 characters for Bitcoin and Tron, 66 for Ethereum/BSC (including the 0x prefix); for USDT the length depends on which network the token was transferred on. Changing even a single symbol in the transaction would change the entire hash — this is what makes the blockchain tamper-proof.
Bitcoin example: 6dcd4ce23d88e2ee9568ba546c007c63d9131c1ae7afdf8d6c2cf52b8a5b8a5e Ethereum / USDT ERC20: 0xa1b2c3d4e5f6... (always starts with 0x) Tron / USDT TRC20: a1b2c3d4... (no prefix, 64 chars)
Is Transaction Hash the Same as TXID?
Yes. Transaction Hash, TXID, TX Hash, Transaction ID — all refer to the same thing. Different platforms use different labels:
Binance — TxID
OKX — Transaction ID / Hash
Bybit — TxID
Trust Wallet — Transaction Hash
MetaMask — Transaction Hash
Etherscan — Txn Hash
Tronscan — Hash
Bitcoin Core — TXID
Don't confuse a transaction hash with a block hash — these are different things. A block contains hundreds of transactions; the block has its own hash, and each transaction inside has a separate one.
What a Transaction Hash Looks Like
Bitcoin (BTC): 64 chars, no prefix. Example: 6dcd4ce2...
Ethereum (ETH, USDT-ERC20): 66 chars, 0x prefix. Example: 0xa1b2c3...
Tron (USDT-TRC20): 64 chars, no prefix. Example: a1b2c3d4...
BNB Smart Chain: 66 chars, 0x prefix. Example: 0xa1b2c3...
Solana: 87–88 chars (typical), no prefix, base58 format
TON: 64 chars, no prefix, base64 format
How to Find a Transaction Hash in Your Wallet
Trust Wallet
Open the app → History
Tap the transaction you need
Scroll to Transaction Hash (or TX Hash)
Tap the icon to copy
Alternatively, «View on Block Explorer» opens the page with the full hash in the URL
MetaMask
Click the extension icon or open the mobile app
Go to Activity
Select the transaction
Click «View on Etherscan» — the URL after /tx/ is your hash
Desktop version: «Copy Transaction ID»
Binance / OKX / Bybit
After a withdrawal:
Wallet → Transaction History (or Wallet → Withdrawal)
Find the right withdrawal
Click it — the TxID field appears
Copy button is right beside it
If the field is empty — the transaction has not yet been broadcast (the exchange holds it until processed)
On the Exchange After a Deposit
Deposit hash is also stored:
Binance: Wallet → Deposit & Withdrawal History → click amount → TxID
OKX: Assets → Funding → Deposit
Bybit: Assets → Funding Account → Deposit Records
How to Verify a Transaction in a Block Explorer
A block explorer is a public website that reads data straight from the blockchain. You can check any transaction without access to the sender's wallet.
Common but not universal URL pattern: https://[explorer]/tx/[YOUR_HASH] — Tronscan and blockchain.com use their own formats (see below).
Bitcoin → Blockchain.com / Mempool.space
https://mempool.space/tx/[hash] — advanced mempool analytics
You'll see: amount, fee, number of confirmations (1 = in a block, 6 = final), time.
Ethereum / USDT ERC20 → Etherscan
https://etherscan.io/tx/[hash]
For USDT on Ethereum the amount appears under ERC-20 Token Transfers — not in the main Value field (which shows 0 ETH; that's normal). For more on USDT regulation across regions see USDT in the EU.
USDT TRC20 → Tronscan
https://tronscan.org/#/transaction/[hash]
Amount under TRC20 Tokens Transferred. Tron finalizes a transaction after 19 super-representative confirmations (~1 minute); individual exchanges and swap services may use different thresholds.
BNB Smart Chain → BscScan
https://bscscan.com/tx/[hash]
Same UI logic as Etherscan.

Why Exchanges Ask for Your Transaction Hash
When you swap crypto on hellchange.top (or any other exchange), you must paste the TXID into the order form or send it to support after payment. Two reasons:
Payment confirmation. Without the hash, the exchange cannot match thousands of daily incoming transfers to your specific order. Manual lookup takes hours. It's also part of the standard AML compliance flow — the operator must confirm the source and fact of the transfer.
Faster processing. With a TXID an operator verifies the status in the explorer in seconds and releases the output. Without it your order waits for automated matching.
How it works on hellchange.top. Once we receive your TXID, the operator locates the payment within seconds and releases the output. Send the hash right after broadcast — don't let it get lost in the inferno of support queues.
The exchange will check confirmations itself — don't wait for them before sending the TXID.
What to Do if a Transaction Is Stuck
If the explorer shows 0 confirmations for over an hour, the transaction is stuck in the mempool purgatory. Causes and fixes:
Low fee (Bitcoin, Ethereum). Networks prioritize higher-fee transactions. Options: wait (it will eventually confirm or drop from mempool after 14 days); Replace-By-Fee (RBF) — rebroadcast the same transaction with a higher fee, but only if the wallet originally flagged it as RBF-replaceable; Child-Pays-For-Parent (CPFP) — broadcast a new transaction that spends the unconfirmed output of the original at a very high fee, making the pair attractive to miners. More on fees in why mining in Russia is getting expensive.
Tron / BSC. Stuck transactions are rare; usually caused by lack of energy/bandwidth (Tron) or gas (BSC). Top them up.
Exchange withdrawal delay. The TX is not yet in mempool — contact the exchange's support with your TXID (they have it but haven't broadcast yet). Similar case study: Garantex and frozen USDT.
Double-sending. Never resend a «copy» — it creates two conflicting transfers that lock funds until auto-resolution.
Common Mistakes When Looking for a TXID
Confusing it with a wallet address. Address = where funds went (bc1q..., 0x..., T...); TXID = the transfer's identifier. Different things.
Copying a shortened hash. Wallet UIs show 0xa1b2...c3d4. You need the full 64–66 chars. Use the Copy button.
Looking for the TXID before broadcast. The hash appears only after the transaction is broadcast. If your wallet shows Pending, the TXID already exists — open the details.
Wrong network. USDT exists on TRC20, ERC20, BEP20, Solana, etc. A TXID from ERC20 won't be found on Tronscan and vice versa.
Missing the USDT amount on Etherscan. Main screen shows Value: 0 ETH — normal. Scroll to Tokens Transferred.
FAQ
What is a transaction hash? A unique identifier for a blockchain transfer — a 64–88 character string. Anyone can use it to look up the transaction on a block explorer.
Are TXID and transaction hash the same? Yes. TX Hash, Transaction ID, TXID — all synonyms.
How do I find a transaction hash in Trust Wallet? History → tap transaction → Transaction Hash field. The View on Explorer button opens the page containing the full hash.
How do I find my TXID on Binance? Wallet → Transaction History → click the transaction → TxID field. Available once the network broadcasts it.
How long is a transaction hash? 64 characters for Bitcoin and Tron, 66 (with 0x prefix) for Ethereum/BSC, 87–88 for Solana.
Can I cancel a transaction using the TXID? No. A broadcast transaction cannot be cancelled. The TXID only lets you check the status (or speed it up via RBF/CPFP if it isn't yet confirmed).
Does a transaction hash reveal my personal data? No. The blockchain shows addresses, amounts, and timestamps — but no names. Privacy holds as long as you didn't publish your address publicly — see also crypto mixers and the legal status of crypto.
My hash isn't found in the explorer — what now? Check the network (USDT TRC20 vs ERC20), make sure the hash was copied without spaces, wait 1–2 minutes after broadcast.
How do I find a transaction hash in MetaMask? Activity → select transaction → View on Etherscan → the URL after /tx/ is the has
Can I send the transaction hash instead of doing the transaction? No. The hash is only a reference. To move funds you must broadcast a real transaction from your wallet.
Why does an exchange need my TXID? To match your specific deposit among thousands and release the output without delay.
Is the transaction hash the same for sender and receiver? Yes. Each transaction has one shared TXID, visible to both parties.
What does «0 confirmations» mean? The transaction has been broadcast but not yet included in a block. Most exchanges wait for 1–6 confirmations depending on the network and amount.
