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 Polygon mainnet.
Chain Name: Polygon Mainnet
Chain ID: 137
RPC URL: https://polygon-rpc.com/
In the "New RPC URL" field, enter the URL of the Polygon mainnet, which is " https://polygon-rpc.com/ ". 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 " MATIC ". This will help you identify the network easily in MetaMask.
Click on the "Save" button to add the Polygon mainnet to your MetaMask interface.
Now you need to select the Polygon mainnet from the network dropdown. Once you select it, your MetaMask will be connected to the Polygon mainnet, and you'll be able to interact with Polygon dapps.
