Notes for Arbitrum API

When communicating with a Arbitrum RPC node, the Arbitrum client implements a JSON-RPC specification, a communication protocol allowing one to make remote calls and execute them as if they were made locally.
The Arbitrum API allows developers to communicate with the Arbitrum blockchain to build applications. The best way to use the Arbitrum API is to use a Web3 library such as web3.js if using JavaScript or web3.py using Python.
