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. Its core component is Polygon SDK, a modular, flexible framework that supports building and connecting Secured Chains like Plasma, Optimistic Rollups, zkRollups, Validium, etc, and Standalone Chains like Polygon POS, designed for flexibility and independence.
It is formerly known as Matic Network, and you might see this version of Polygon pop up in some places.
Essentially, Polygon is a scaling solution for Ethereum with rapid adoption by many DeFi protocols like Curve, Aave, Sushiswap, mStable and more.
Many users enjoy using Polygon for its extremely low gas fees, with transaction fees cheaper than $0.001 and rapid transaction speeds.
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 Matic Mainnet settings as follows:
- Network Name: Polygon
- New RPC URL: https://polygon-rpc.com or
https://rpc-mainnet.matic.network or
https://rpc-mainnet.maticvigil.com or
- ChainID: 137
- Symbol: MATIC
- Block Explorer URL: https://polygonscan.com/
Click Save.
You have now connected to the Matic mainnet with your Metamask Wallet!
Transactions on the Polygon network requires its native token MATIC which will be used as gas fee.

Polygon RPC aggregator
Polygon RPC Aggregator, which aims to provide a fast and reliable RPC gateway, is now live as of August 2021.
This service is distributed worldwide across 200 data centres with underlying RPC endpoints provided by Polygon Node providers, the Polygon team, and the community.
It has a monitoring system that constantly monitors the RPC endpoints and ensures that they are healthy and in sync. It also has an intelligent caching system that makes things faster and offloads traffic to alternative nodes when needed.
To use the RPC aggregator, use the RPC URL: https://polygon-rpc.com
