How to add Optimism to MetaMask
Adding Optimism to MetaMask takes a few seconds. Modern wallets can add it automatically, or you can enter the network details manually.
The easy way (automatic)
Visit our Optimism token creator and connect — the site prompts MetaMask to add and switch to Optimism in one click. Most dApps do the same.
Manual network details
In MetaMask open Settings → Networks → Add network → Add manually and enter:
- Network name: OP Mainnet
- RPC URL: https://mainnet.optimism.io
- Chain ID: 10
- Currency symbol: ETH
- Block explorer: https://optimistic.etherscan.io
Get ETH on Optimism
You need a little ETH on the Optimism network. Withdraw ETH from an exchange on Optimism, or bridge from Ethereum.
Stay safe
Only add networks from official sources. Never enter your seed phrase on any "add network" page — it is never required. See avoiding scams.
