1. Set Up Fiamma Operator

Steps overview:

1. Clone the repository

2. Set up the environment

3. Configure environment variables

Step 1: Clone the Repository

First, clone the repository to your local machine:

git clone https://github.com/fiamma-chain/operator_for_linux.git
cd operator_for_linux

Step 2: Set up the Environment

Run the setup script to install all dependencies and prepare your environment:

./setup.sh

Important: After the first execution of setup.sh, you need to enable the Rust environment variables:

source "$HOME/.cargo/env"

Alternatively, you can restart your terminal or run:

source ~/.bashrc
# or if you're using zsh:
source ~/.zshrc

This script will:

• Install required packages (build-essential, gcc, g++, libssl-dev)

• Install and configure PostgreSQL

• Install Docker and Docker Compose (if not already installed)

• Install Rust and SQLx CLI

• Create a default .env file from .env_example

• Set up database and Redis containers

• Grant execute permissions for scripts

Next, run database migrations to set up the required database schema:

cd dal && cp .env.example .env && sqlx migrate run && cd ..

Step 3: Configure Environment Variables

• Prepare three BTC addresses to process transactions:

  • Main address (auth): The address operator deposits funds to

  • Pegin address: The address responsible for processing deposit transactions

  • Pegout address: The address responsible for processing withdraw transactions

• Note: Please use p2tr type addresses

Edit the .env file:

• vim .env

Enter the three private keys from your addresses:

BITVM_BRIDGE_OPERATOR_AUTH_SK=your_auth_private_key
BITVM_BRIDGE_OPERATOR_PEGIN_SK=your_pegin_private_key
BITVM_BRIDGE_OPERATOR_PEGOUT_SK=your_pegout_private_key

• Note: These private keys are essential for the Operator to function correctly and should not be the same.
