# 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)
