kuberstack/upmyfee repository overview

⁠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
