## Introduction
In ERC-4337, a Bundler is the core infrastructure component that allows account abstraction to work on any EVM network. On the highest level, its purpose is to work with a mempool of User Operations to get the transaction to be included on-chain.

This project allows you to deploy the ALTO bundler application on Railway with support for Arbitrum. ALTO is a platform designed to provide decentralized orchestration for blockchain-based tasks, specifically functioning as a Bundler for ERC-4337.
