   • RAM: 8+ GB.
   • Storage: 100+ GB of SSD storage.

3. Install docker-compose:

   sudo apt update
   sudo apt install docker-compose
   
   

4. Set Up a Forta Wallet: Create or import an Ethereum wallet for Forta node interactions. You’ll need the wallet’s private key and enough ETH to cover transaction fees.

5. Install Node.js: Node.js is required for the Forta CLI. Install it by running:

   curl -fsSL <https://deb.nodesource.com/setup_18.x> | sudo -E bash -
   sudo apt install -y nodejs
   
   

Step 1: Install the Forta CLI

The Forta CLI is used to initialize and manage the validator node.

1. Install the CLI globally:

   npm install -g @forta/cli
   
   

2. Verify the installation:

   forta --version
   
   

Step 2: Initialize the Node

1. Run the initialization command:

   forta init
   
   

2. Provide the following details when prompted:

   • Forta Wallet Private Key: Enter the private key of your Forta wallet.
   • Node Type: Select "Validator."

Step 3: Configure the Node

After initialization, a config.yml file will be created in the Forta node directory.

1. Open the config.yml file for editing:

   nano config.yml
