Can I Add Optimism to MetaMask?

You can add Optimism to MetaMask, as it’s an Ethereum Layer 2 network supported by EVM-compatible wallets. Optimism uses Optimistic Rollups for faster transactions while maintaining Ethereum’s security. To connect, simply enter the network name, chain ID, and RPC URL for Optimism in MetaMask’s settings.

How to Add Optimism to MetaMask

Adding Optimism to MetaMask is simple due to its Ethereum Virtual Machine (EVM) compatibility. A quick way to set it up is by using ChainList, which simplifies connecting to Optimism with accurate network details in just a few steps.

Here’s how to add Optimism:

1. Visit ChainList: Go to ChainList and connect your MetaMask wallet.
2. Search for Optimism: Use the search bar to look for "OP Mainnet."
3. Add the Network: Click on Optimism in the results, then select "Connect Wallet."
4. Complete Setup: Follow MetaMask’s prompts to finalize adding Optimism to your network list.

Optimism RPC and Chain ID

To manually add Optimism to MetaMask, use the following network settings. Double-check these details with the official Optimism documentation to ensure accuracy:

• Network Name: OP Mainnet
• RPC URL: https://mainnet.optimism.io/
• Chain ID: 10
• Currency Symbol: ETH
• Block Explorer URL: https://explorer.optimism.io/

Enter these settings in MetaMask to securely connect and access Optimism’s dApps and services.

About Optimism

Optimism is an Ethereum Layer 2 solution utilizing Optimistic Rollups for fast, cost-efficient transactions while preserving Ethereum’s security. Built on the open-source OP Stack, Optimism supports the creation of interconnected Layer 2 chains within a unified “Superchain” framework, enabling composability across blockchains. 

Governed by the Optimism Collective, it promotes community-driven governance and funds public goods, aiming for scalable, decentralized blockchain infrastructure.

Bottom Line

Integrating Optimism with MetaMask is quick and unlocks Ethereum’s Layer 2 advantages, combining lower fees with faster transaction speeds for dApp access. 

By adding Optimism, users benefit from Ethereum-level security with improved cost efficiency, making it a powerful tool for expanding DeFi opportunities directly in MetaMask.
