Getting Started with Polygon on Metamask

Updated: May 30, 2022

MetaMask is the most popular cryptocurrency wallet app and browser extension used to access the Web3 universe. In just a few simple steps, you can unlock this powerful tool and begin exploring the Polygon ecosystem.

There are more than 19,000 decentralized applications (dApps) running on Polygon. That list includes DeFi protocols like Aave and Uniswap V3, NFT marketplaces OpenSea and Mark Cuban’s Lazy.com and Web3 gaming efforts including DraftKings, Animoca Brands’ The Sandbox and Decentral Games. There is a lot to see, so let’s get you set up.

Setting Up

If you don't already have MataMask, setting one up is a breeze:

  1. MetaMask is available for download and installation on a variety of platforms with two main flavors: desktop browser (Chrome, Firefox, Brave, and Microsoft Edge) and mobile (iOS and Android). Get the one that’s right for you from the official website.

  2. After you've downloaded and installed the extension or app, launch it and click 'Get Started.'

  3. If this is your first time creating a MetaMask wallet, click the 'Create a Wallet' button. You can also use a Secret Recovery Phrase to import your existing MetaMask wallet.

  4. In order to improve MetaMask, you have the option of sharing anonymous usage data with MetaMask. This can be turned off at any time by going to Settings and unchecking the box.

  5. Create a password. MetaMask will then share with you your Secret Recovery Phrase, which serves as the master key to our wallet and will let you regain access to your account if you lose the password.

  6. Click 'Next' to see your 12-word seed phrase. Verify it by selecting each word in the correct sequence. Click "Confirm."

  7. We recommend that users keep their seed phrase offline and in a secure location. Sharing it with someone is the same as handing over your wallet.

  8. You've now completed the setup process for your MetaMask wallet. Click 'All Done.'

Connecting to Polygon

MetaMask is set up for use on Ethereum by default. You will need to connect the Polygon network first.

Connect Manually

  1. On mobile, click the hamburger icon in the top left, go to Settings and down to Networks. On the browser, the network selection window is usually in the top right.
