# Add Polygon network to MetaMask

First, you need to map a new network (i.e. *Polygon*) on your wallet. Hereafter, we will use the Metamask wallet. You can either choose to add *Polygon* manually or automatically using third party services.

### Add *Polygon* manually

Click on your *Metamask* extension, select *Ethereum* mainnet and choose Custom RPC from the list. Fill in the menu with the following information:

![Metamask's network list before adding Polygon](/files/6Fg1bAUEP25muMZzPSgg)

* Network Name: Polygon Mainnet 
* New RPC URL: [https://polygon-rpc.com/ ](<https://polygon-rpc.com/ >)
* Chain ID: 137&#x20;
* Currency Symbol (optional): Matic&#x20;
* Block Explorer URL (optional): <https://polygonscan.com/>

### Add *Polygon* through *Chainlist*

Visit [www.chainlist.org](https://chainlist.org/) to add *Polygon* to *Metamask*. Connect your wallet to the *Chainlist* dApp in the top right corner. Once connected, search *Polygon*, choose *Polygon* Mainnet and select Add to *Metamask*. *Metamask* will ask “Allow this site to add a network?” approve it, then select *Switch Network*. You should now see *Polygon* Mainnet in the *Metamask* networks drop-down list.

*Matic*, used to cover gas fees on the *Polygon* network, will be listed automatically. If you want to add some additional tokens to your balance click on Import tokens. To add *$IDLE* tokens to your wallet list:

* Token Contract Address: [0xc25351811983818c9fe6d8c580531819c8ade90f](https://polygonscan.com/token/0xc25351811983818c9fe6d8c580531819c8ade90f)
* Token Symbol: *IDLE* (autogenerated)
* Token Decimal: 18 (autogenerated)

Similarly, you can add [WETH](https://polygonscan.com/token/0x7ceb23fd6bc0add59e62ac25578270cff1b9f619) or any other token of your choice. Always remember to look for the Polygon contract address.

Once mapped the new network you can visit [www.polygon.idle.finance](https://polygon.idle.finance)

## 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.idle.finance/other/archive/idle-on-polygon/add-polygon-network-to-metamask.md?ask=<question>&goal=<endgoal>
```

`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.
