MetaMask is a crypto wallet app and browser extension that, by default, is connected to the Ethereum Mainnet. You can find the extension on the official MetaMask website, which will direct you to the correct place to download it. To connect to other networks like Polygon, you'll need to add some basic blockchain information to MetaMask. This includes a custom RPC URL, chain ID, and network name. To add Polygon tokens, a token address must be imported. Learning to add a new blockchain to MetaMask is a transferable skill and can be used to add other EVM networks like Binance Smart Chain.
Interacting with the Polygon blockchain requires a compatible crypto wallet such as MetaMask. However, MetaMask doesn’t have Polygon added as a network by default. Setting up your browser wallet to connect to Polygon is simple and can be done in just a few minutes.

Create a password
Choose a secure password to log in to your wallet from your browser. Note that this is not your seed phrase. The password is a security measure to prevent anyone using your device from accessing your wallet. If you forget your password, you can always access your crypto with your seed phrase.
Secure your Wallet
After choosing your password, MetaMask will present you with information regarding your wallet’s seed phrase. Make sure to read through it if you aren’t familiar with how a crypto wallet works.
Secret Recovery Phrase
You’ll now be presented with your seed phrase. Click the lock to view the words and take note of them in the correct order. Keep the phrase in a secure place (preferably offline) and never share it with anyone. This string of numbers is the final backup of your wallet and its contents. Click [Next] to continue.
Confirm your Secret Recovery Phrase
You’ll now have to repeat your seed phrase by selecting the words at the bottom of the screen in the right order. Click "Confirm" once this is complete.
