# Adding Polygon (Matic) Network to MetaMask
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:
**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 . 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.gamecredits.org/general/adding-polygon-matic-network-to-metamask.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
