Capstone Project: Bitcoin Core CLI Automation

Goal

Build a complete command-line tool or script that simulates a full Bitcoin transaction cycle using bitcoind, bitcoin-cli, and regtest.

This project tests your ability to:

Operate and script around a Bitcoin Core node

Manage wallets and UTXOs

Create, sign, and broadcast raw transactions

Work entirely from the command line or via a scripting language

Your tool (Bash, Python, or any CLI language) should do the following:

Check if bitcoind is already running. If not, start it with:

Checking running process

Create a wallet and a miner address:

Create Wallet

Mine 101 blocks to unlock coinbase outputs:

Mine block

Generate two new recipient addresses:

Generate new addresses

Send 0.25 BTC to each:

Send to Multiple Recipients

Mine 1 block:

Mine block

Retrieve and decode the transaction:

Mine block

Your tool must:

Be runnable from a single command or script

Wallet balance before and after TX

The full transaction hex

The decoded transaction JSON

Handle errors gracefully (e.g. wallet already exists)

🔍 Decoded Transaction:
