Add Optimism To MetaMask – 3 Simple Methods

This article breaks down all the different ways you can add the Optimism blockchain to MetaMask. We’ll also look at adding the Optimism token to MetaMask. Let’s get started.

How To Add Optimism To MetaMask

One of the fastest ways to add Optimism to MetaMask is by using MetaMask’s built-in interface. Start by logging in to your MetaMask account, click the network tab, and click “Add Network.”

On the Network Settings page, you’ll see the Optimism logo next to an “add” button. Click “add,” then click “approve” on the next screen. Now you have successfully added Optimism to MetaMask! You can also add other blockchains like Arbitrum to MetaMask using this method.

How To Manually Add Optimism To MetaMask

If, for whatever reason, the above method isn’t working, you can also manually add Optimism to MetaMask by inputting the details yourself.

Start by logging into MetaMask, then click the Network tab and click “Add Network.” Once you’re on the Network Settings page, go to the bottom and click on “Add a network manually.”

Now that you’re on the add “a network manually page,” start by filling in the blank fields with the information below. 

  • Network Name: Optimism
  • RPC URL:
  • ChainID: 10
  • Symbol: ETH
  • Block Explorer URL: 

Remember to use ETH as the currency symbol since gas fees are paid in ETH on the Optimism network. If you enter OP, you won’t be able to connect to the network. Make sure to enter the information without any spaces or blank characters, as the extra space will cause MetaMask to read the information wrong.

If you notice that the Optimism blockchain is slow or overloaded with transactions, you can switch to a different RPC, which can help your transactions go through. You can think of a RPC as a server that lets you connect to a blockchain. Switching RPCs is something you can try when you notice the network is overloaded.

Ankr, Omnia, 1RPC, and LavaNet all provide their own RPCs for the Optimism blockchain, and they can help you escape blockchain congestion. Simply replace the link in the RPC with one of the links below:

Add Optimism To MetaMask Using Chainlist

Another quick way to add Optimism to MetaMask is by using Chainlist. Chainlist is a reputable website that makes it easy to connect to different blockchains within a few clicks.

Now that you’re done connecting your wallet to Optimism, it’s a good idea to disconnect your wallet from Chainlist. Even though Chainlist is a safe and reputable website, it’s a good idea to reduce your exposure to risk by minimizing how many websites your MetaMask wallet is connected to. 

Click on the MetaMask icon, then click on the Globe symbol. Next, click on the three dots next to your account number. Finally, click on “disconnect account”
