Overview
Create a high-fee transaction with the same transaction structure. Nodes will remove the original low-fee transactions and instead accept higher-fee transactions, thereby speeding up transaction confirmation. No service fee will be charged if unsuccessful.
Step 1: Enter the unconfirmed transaction hash or raw transaction (rawtx)
Step 2: Select content to adjust
-
Adjust the output
Select an receiving address that can modify the receiving amount from the output(recipients) of the original transaction
-
Don’t adjust output
The recipients and amount remain unchanged of the original transaction, and the sending amount will be adjusted.
Step 3: Confirm transaction content
After confirming the relevant fees, click ‘Pay & Sign’
Step 4: Sign transaction
After the signed transaction is completed, the raw transaction (rawtx) of the new transaction can be broadcast to multiple nodes faster through the transaction broadcast tool (https://tools.btc.com/zh-CN/tools/broadcast), so that the transaction can be confirmed faster.
