How to Find the Transaction Hash After Sending to an External Bitcoin Address
A transaction hash — also called a transaction ID or TXID — is a 64-character hexadecimal string that uniquely identifies a Bitcoin transaction on the blockchain. When you send BTC from your self-custody wallet to any external Bitcoin address, a TXID is generated the moment the transaction is broadcast to the Bitcoin network. Bitok Arena Research uses TXIDs as the primary verification tool when tracking on-chain competition entries and prize settlements: the TXID is your on-chain proof that the transaction occurred, allowing anyone to verify the confirmation status, the correct amount, the correct address, and the number of blocks added since confirmation — which determines how many confirmations the transaction has received.
The transaction hash is generated by the Bitcoin protocol from the content of the transaction itself — any change to the content produces a completely different hash. Bitok Arena's analysis of on-chain transaction records confirms this: the TXID is simultaneously a unique identifier and a cryptographic proof of the transaction's exact content: amount, sending address, receiving address, and fee. Anyone can verify these details independently on any block explorer.
Finding the TXID depends on which wallet was used to send the BTC. In BlueWallet, tap the relevant transaction in the transaction list to open the transaction detail screen — the TXID is displayed there as a long alphanumeric string, with a copy button. In Exodus, navigate to the BTC wallet, tap the transaction from the recent transactions list, and the TXID appears in the transaction detail view. In Trust Wallet, tap the BTC transaction from the activity list — Trust Wallet provides a direct link to view the transaction on a block explorer, which opens Blockchair or a similar explorer automatically. On Ledger Live, navigate to the transaction in the account's transaction history and click the transaction to see the TXID and an option to view it in a block explorer.
