How to add the Polygon to MetaMask
Overview
By default, Metamask supports the Ethereum mainnet and some testnets. In order to use Metamask with dapps running on the Polygon, we need to add this network manually to MetaMask. This article provides instructions to do so.
Instructions
Adding a New Network
Open Metamask
Click on your user icon on the top right
Click "Settings"
Click "Networks"
Click "Add Network" at the bottom
BSC Network Details
Network Name: Polygon
New RPC URL: https://polygon-rpc.com/
Chain ID: 137
Currency Symbol: MATIC
Block Explorer URL: https://polygonscan.com/
Click "Save" and you are done. Now when you want to use a dapp on Polygon, make sure the "Polygon" network is selected on the network dropdown on the top part of the main view of Metamask.
