To start the process, open the MetaMask extension in your browser by clicking on the MetaMask icon located in the top-right corner. This will open the MetaMask interface, which provides an intuitive and user-friendly interface for managing your assets.
In the MetaMask interface, click on the network dropdown in the top-right corner. From the list of options, select "Custom RPC". This will open a new window where you can enter the details of the Avalanche mainnet.
Chain Name: Optimism
Chain ID: 10
RPC URL: mainnet.optimism.io
In the "New RPC URL" field, enter the URL of the Avalanche, which is " mainnet.optimism.io ". It is important to double-check the URL to ensure you are connecting to the correct network.
In the "Network Name" field, give the network a name. For example, you can call it " Optimism ". This will help you identify the network easily in MetaMask.
Click on the "Save" button to add the Avalanche Network mainnet to your MetaMask interface.
Now you need to select the Optimism Network from the network dropdown. Once you select it, your MetaMask will be connected to the Optimism Network mainnet, and you'll be able to interact with Optimism Network dapps.
