Metamask is a digital wallet that allows you to securely store, send, and receive cryptocurrencies and other blockchain assets. It is a browser extension that can be added to Google Chrome, Firefox, Brave, and other popular web browsers.
The Polygon Network, formerly known as the Matic Network, is a Layer 2 scaling solution for Ethereum. It is a sidechain that operates alongside the Ethereum network, providing faster and cheaper transactions. Polygon Network allows developers to build decentralized applications (dApps) that can utilize the security and reliability of the Ethereum network while taking advantage of faster and cheaper transactions on the Polygon sidechain.
Here is a step-by-step guide on how to open a Metamask wallet and switch it to the Polygon Network:
First, visit the Metamask website (https://metamask.io/) and download the extension for your preferred browser.
Once installed, open the extension and create a new wallet by following the prompts. Be sure to securely store your seed phrase as this is your backup in case you ever lose access to your wallet.
After creating your wallet, click on the network dropdown in the top right corner of the Metamask window and select "Custom RPC."
In the "New RPC URL" field, enter "https://rpc-mainnet.maticvigil.com/" for the Mainnet or "https://rpc-mumbai.maticvigil.com/" for the Mumbai Testnet.
Next, enter a custom name for the network (e.g. "Polygon" or "Matic") and the currency symbol if desired.
Click "Save" and your Metamask wallet will now be connected to the Polygon Network.
That's it! You now have a Metamask wallet that is connected to the Polygon Network, allowing you to send and receive transactions on this sidechain.
