# Adding Polygon Network to your Wallet

### Setup your MetaMask Wallet to use Polygon <a href="#metamask-wallet" id="metamask-wallet"></a>

Metamask is a browser add-on that manages a user’s Ethereum wallet by storing their private key on their browser’s data store and the seed phrase encrypted with their password.

It is a non-custodial wallet, meaning, the user has full access and responsibility their private key. Once lost, the user can no longer control the savings or restore access to the wallet.

Interacting with LeagueDAO on Polygon will be just like on Ethereum, you will use MetaMask to sign and approve transactions to purchase LeagueDAO NFTs and interacting with our apps like the Nomo Leagues.

&#x20;Install the Metamask Extension from the Store

Visit the [browser extension marketplace](https://chrome.google.com/webstore/detail/nkbihfbeogaeaoehlefnkodbefgpgknn) and download the MetaMask extension.
