How to Add Optimism to MetaMask


Optimism is a decentralized layer-2 Ethereum scaling solution that helps to reduce transaction costs and speeds up transactions on the Ethereum network. MetaMask is an Ethereum wallet that securely stores your Ethereum and other cryptocurrency tokens. This guide will show you how to add Optimism to MetaMask and use it as an additional source of funds for trading.

Overview of Optimism layer 2 solution

Founded in 2017 and backed by prominent venture capitalists such as a16z, Polychain Capital, and Paradigm, Optimism has raised a considerable sum of $150 million as of 2022. Dedicated to promoting the use of Ethereum through layer 2 scaling solutions, Optimism utilizes its proprietary Optimistic Virtual Machine (OVM). This roll-up technology enables users to experience faster transactions at reduced costs while maintaining the security mechanisms of the Ethereum blockchain. In addition, OVM integrates advanced financial modeling capabilities and allows developers to create applications relying on trustless protocols that can still interact with each other.

Benefits of using Optimism L2

Optimism L2 is an exciting solution for businesses looking to accommodate increasing demands for decentralized applications.

  1. By utilizing the unique features of an Optimistic Virtual Machine (OVM), Optimism L2 offers users cheaper and faster transactions than Ethereum’s mainnet while retaining all the essential security properties of Ethereum, such as finality and liveness.
  2. It excels in providing increased scalability when compared to traditional solutions in the blockchain sphere. As a result, companies can now scale their applications without sacrificing security or decentralization.
