A Comprehensive Guide to How to Run Arbitrum Node

In the blockchain space, scalability is crucial. Even one of the pioneering platforms for dApps & smart contracts, Ethereum faces limitations in transaction throughput and high gas fees due to its design. However, solutions like Arbitrum offer a promising path forward by introducing Layer 2 scaling solutions. These solutions aim to enhance Ethereum’s capabilities by processing transactions off-chain while leveraging Ethereum’s security. And that’s why we are here today with this comprehensive guide to how to run Arbitrum node.

Running an Arbitrum node opens doors to a faster, more efficient Ethereum ecosystem. It doesn’t matter if you are a developer, enthusiast, or stakeholder in the DeFi space – setting up an Arbitrum node allows you to actively contribute to Ethereum’s scalability efforts. This step-by-step post will go from installing-configuring to maintaining an Arbitrum node. You will also learn to prepare your environment for monitoring node performance and everything else required to become a part of Ethereum’s Layer 2 revolution. Let’s begin!

Preparing Your Environment

The system environment must meet the requirements for setting up the Arbitrum node. You will need a machine with sufficient resources, preferably a Linux-based operating system like Ubuntu. Ensure you have a stable internet connection and enough disk space to store the blockchain data. Look at some figures below:

Hardware Requirements

Desktop Computer Specs

  • Processor: 6667+
  • RAM: minimum of 16 GB, 32 GB is better.
  • SSD Storage: At least 1TB

NUCs or Mini PC specs

  • Processors: 8th gen or higher Intel NUC
  • RAM: 16 GB or 32 GB
  • SSD Storage: 1TB-2TB SSD Drive

Software Requirements

  • Operating System: Ubuntu or Linux (Recommended)
  • Ethereum Node Software

Two different types of software are needed for running an Ethereum full node, i.e., – Execution Client & Consensus Client.

How to Run Arbitrum Node?

Step 1: Installing Dependencies

Arbitrum requires some dependencies to be installed on your machine. Begin by installing Node.js, Git, and Docker if you haven’t already. Use the following commands:


sudo apt update
sudo apt install nodejs npm
sudo apt install git
sudo apt install

Verify the installations by checking the versions:


Copy code
node -v
npm -v
git --version
docker --version

Step 2: Cloning the Arbitrum Repository

Next, clone the Arbitrum repository from GitHub using Git. Navigate to the directory where you want to store the Arbitrum code and execute the following command:


git clone

This will create a local copy of the Arbitrum repository on your machine.

Step 3: Building Arbitrum Docker Images

Arbitrum utilizes Docker containers for running its node. Navigate to the Arbitrum directory and run the build script to build the Docker images:


cd arbitrum

This script will download the necessary dependencies and build the Docker images required for running Arbitrum.

Step 4: Configuring Arbitrum Node

After building the Docker images, it’s time to configure your Arbitrum node. Navigate to the docker directory within the Arbitrum repository and create a configuration file named config.toml:


cd docker
touch config.toml

Edit the config.toml file with your preferred text editor and specify the configuration parameters according to your preferences. You can adjust parameters such as Ethereum RPC endpoint, database settings, and logging options.

Step 5: Starting Arbitrum Node

With the configuration in place, you can now start your Arbitrum node using Docker. Run the following command from the docker directory:


docker-compose up

This command will start the Arbitrum node based on the configuration provided in the config.toml file. You will see logs indicating the progress of the node initialization.

Step 6: Monitoring Your Arbitrum Node

Once your Arbitrum node has started running, you may want to monitor its performance & status. Arbitrum provides a monitoring dashboard that you can access through your web browser. Open your browser and navigate to http://localhost:8000 to access the dashboard.

The dashboard displays various metrics and information about your Arbitrum node, including block processing speed, transaction throughput, and network connectivity.

Step 7: Interacting with the Arbitrum Node

To interact with your Arbitrum node, you can use the Arbitrum command-line interface (CLI) provided in the repository. Navigate to the arb-cli directory and install the necessary dependencies:


cd ../arb-cli
npm install

Once the dependencies are installed, you can use the CLI to interact with your Arbitrum node. For example, you can query the current block number using the following command:


npm run query getBlockNumber

This will return the current block number processed by your Arbitrum node.

Step 8: Maintaining Your Arbitrum Node

To ensure smooth operation of your Arbitrum node, regularly update the Arbitrum repository to fetch the latest changes and improvements. Navigate to the Arbitrum directory and pull the latest changes from the upstream repository:


cd ../arbitrum
git pull origin master

After pulling the changes, rebuild the Docker images as mentioned in Step 4 to incorporate the updates into your node.
