Please note that it is not required to add the Matic network to MetaMask to interact with the GAME Credits Portal. However, doing so will allow you to easily track your GAME balance on the Matic Network and may be required to view and trade your NFTs created or bought on the GAME Credits Portal when using third-party platforms such as Opensea.
We recommend you check the Matic/Polygon documentation hub for the most up to date configuration information. This can be found here: https://docs.matic.network/docs/develop/metamask/config-matic/
Step 1: Add A Custom RPC
Open MetaMask and login.
To add Matic’s Mainnet, click on the Network selection dropdown and then click on Custom RPC.
Step 2: Add Matic Mainnet Information
Once you click “Add Custom RPC,” it will open up a form with 2 tabs on the top, Settings and Info. In the Settings tab you can add the URL https://rpc-mainnet.maticvigil.com/. Ensure you’ve typed every field in as displayed below, including the “Network Name” as you’d like it to be displayed.
Once you’ve added the URL in the New Network field, click on Save. You will be directly switched to Matic’s Mainnet now in the network dropdown list. You can now close the dialog.
