upmyfee's Introduction

UpMyFee

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.

How it works?

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

More details?

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

Requirements

Bitcoin node with the RPC access and address from where the transaction was sent. --txindex flag is required.
Python 3
Python requests

upmyfee's Issues

is this script still working?

could you explain me better how this script works? Can I change the BTC receipt wallet for unconfirmed transactions on the blockchain?
I don't know much about programming, but I would like to use this script. If you can help me, I thank you very much.

Can this script still be used? I have the following problem

Traceback (most recent call last):
File "C:\Users\user\upmyfee\upmyfee.py", line 148, in
upmyfee.change_fee(payer, to, txid, fee, debug)
File "C:\Users\user\upmyfee\upmyfee.py", line 87, in change_fee
vin, vout, orig_fee, fee_diff, orig_amount, new_amount = self.get_new_tx(orig_tx, payer, to, fee)

raise JSONRPCException(response['error'])
