Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks.
It is an easy-to-use platform for Ethereum scaling and infrastructure development.
It is formerly known as Matic Network, and you might see this version of Polygon pop up in some places.
In this guide, we will show you how to setup Metamask for Polygon.
Install the Metamask Extension from the Store
Visit the browser extension marketplace and download the MetaMask extension.
Create a MetaMask Wallet or Import One
I’d suggest creating a new one if you haven’t done so.
Click import wallet if you have an existing wallet.
Setup your password and secret recovery phrase somewhere safe.
Setup MetaMask to connect to Matic Network
Switch the connected blockchain by clicking on the tab saying Main Ethereum Network, we need to add the Matic network.
Scroll down until you find Custom RPC.
Enter in the Polygon/Matic Mainnet settings as follows:
- Network Name: Polygon
- New RPC URL:
https://rpc-mainnet.matic.network or
Using https://polygon-rpc.com is most recommended as it aggregates multiple RPC URLs! See below for more information.
- ChainID: 137
- Symbol: MATIC
- Block Explorer URL: https://polygonscan.com/
Click Save.
You have now connected to the Polygon / Matic mainnet with your Metamask Wallet!
