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 BNB Smart Chain mainnet.
Network Name: Arbitrum One
New RPC URL: https://arb1.arbitrum.io/rpc
Block Explorer URL: https://arbiscan.io/
In the "New RPC URL" field, enter the URL of the Arbitrum One mainnet, which is " https://arb1.arbitrum.io/rpc ". 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 " Arbitrum One ". This will help you identify the network easily in MetaMask.
Click on the "Save" button to add the Arbitrum One mainnet to your MetaMask interface.
Now you need to select the Arbitrum One mainnet from the network dropdown. Once you select it, your MetaMask will be connected to the Arbitrum One mainnet, and you'll be able to interact with Arbitrum One dapps.
