Script for change Bitcoin transaction fee (only unconfirmed).
Sometimes transactions in Bitcoin are confirmed for a very long time. This is usually due to network congestion and / or low commission.
If the transaction does not have any confirmation yet, you can correct the situation.
Also you can change recipient address of unconfirmed transaction.
This script creates a new transaction, similar to the original, but with a large fee and new recipient address.
Why you need create new recipient addres?
Because if you submit some transaction with some addresses - you can receive
Error #-26: 18: txn-mempool-conflict
Application use Bitcoin RPC for:
- get and decode raw transaction
- get vin transactions for create new tx
- change one tx vout amount for extend fee
- create and sign new raw transaction
- send edited transaction to Bitcoin Blockchain
- Bitcoin node with the RPC access and address from where the transaction was sent.
--txindexflag is required. - Python 3
- Python requests
