Optimism is a layer 2 scaling protocol for Ethereum network.
It’s designed to be fast, simple and secure, while helping people send transactions, similar to Ethereum with more advantages.
These advantages that we’re talking about are:
- Instant transaction finality
- Lower transaction fees.
However, you can add Optimism to MetaMask wallet by adding the RPC endpoints of the network to your account.
Of all the software wallets you can use for cryptocurrencies, MetaMask is a popular solution.
Practically, any DeFi application and almost all blockchains (except Bitcoin blockchain) integrates with it.
This guide will walk you through the easiest way you can add Optimism RPC details to your MetaMask wallet account.
Let’s get started.
How to add Optimism to MetaMask
In this tutorial, it’s totally assumed that you have already downloaded and installed the MetaMask on your device (either as; browser extension or mobile app).
Otherwise, you should go-to the official website and follow the procedures on how to install and use the software wallet.
Before we start the process of adding funds to MetaMask with the L2 network, let me first give you the RPC information.
