Run a serverless Arbitrum full node on AWS

Over the last 2 years, layer 2 technologies have gained traction and are solving the scaling constraints of Ethereum. L2beat provides a consolidated view of the different layer 2 projects. At the time of writing, Arbitrum represents approximatively half of the market value of layer 2 solutions.

AWS offers a variety of services to help builders from node deployment blueprints to fully managed infrastructure and data services on Amazon Managed Blockchain. Although Arbitrum is not yet supported, running your own serverless Arbitrum node on AWS is an uncomplicated task.

In this post, we show you how to deploy an Arbitrum full node in a serverless manner on AWS. We also illustrate how to interact with the Arbitrum network by connecting MetaMask to your Arbitrum node. To follow these instructions, you only need a working AWS account.

Solution overview

There are multiple considerations for running an Arbitrum full node, including transaction validation and security, and reduced trust requirements. The How to run a full node (Nitro) section of the Arbitrum documentation contains the prerequisites and instructions to run an Arbitrum full node. In this post, we propose an AWS architecture to address those requirements. This architecture is not intended to represent the single source of truth, but instead a way of implementing those requirements favoring serverless services like AWS Fargate. Alternatives based on Amazon Elastic Compute Cloud (Amazon EC2) instances would be as valid as the one presented here.

The following diagram shows the different components of the solution.
