Multisig Wallet Workshop

Overview

This workshop will guide you through the creation of a multisig wallet using Python and the Bitcoin utilities library. A multisig wallet requires multiple signatures to authorize a transaction, enhancing security.

Prerequisites

Before you begin, ensure you have the following installed:

• Python 3.x
• Git

Quick Start

1. Clone the repository:

git clone <repository-url>
cd <repository-name>

2. Run the setup script:

chmod +x setup.sh
./setup.sh

This will:

• Create a Python virtual environment
• Install all required dependencies
• Make the program executable

3. Activate the virtual environment:

source .hxckr/bin/activate

Manual Setup

If you prefer to set up manually, you can:

1. Create a new virtual environment:

python3 -m venv .hxckr

2. Activate the virtual environment:

source .hxckr/bin/activate

3. Install the required packages:

pip install -r requirements.txt

Passing the First Stage

The entry point to the workshop is the main.py file. To pass the first stage, you need to create an empty commit and push it to the remote repository.

git commit --allow-empty -m "Pass the first stage"
git push

Passing Other Stages

Study the code in the main.py file and fix the bugs. There are comments in the code that will guide you to the solution. When you are done, create a new commit and push it to the remote repository.

git commit -am "Pass the stage"
git push

You can also run the program manually to test your changes.

./your_program.sh

Goals

• Fix the bugs in the program

Bugs

1. Missing validation for required_signatures > 0
2. Ignoring config parameter
3. Missing initialization of redeem_script and addresses
4. Not clearing existing keypairs before generating new ones
5. Not calling create_multisig_addresses()

Fixing the Bugs

1. Add a check for required_signatures > 0
2. Add a check for config parameter
3. Initialize redeem_script and addresses
4. Clear existing keypairs before generating new ones
5. Call create_multisig_addresses()

Exit the virtual environment
