Getting Started with MetaMask on Polygon:

MetaMask is a widely used crypto wallet app and browser extension that enables users to interact with Web3 projects. In just a few simple steps, anyone can set up a MetaMask wallet and begin exploring the Polygon ecosystem.

There are tens of thousands of dApps (decentralized applications) running across the Polygon Proof-of-Stake (PoS) network. With the ecosystem explorer, you can browse projects across all Polygon protocols (including Polygon) and select what's right for you. There's a lot to see, so let’s get started!

Setting up MetaMask wallet:

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

  5. 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.

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

  10. 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.

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