How do I Connect Polygon (MATIC) to MetaMask

By The Glitcher | The Glitcher | 7 Aug 2021

Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks. It provides scalable solutions on top of Ethereum multiple side chains ecosystem. It is also known as layer 2 scaling solution as it provides scalability on the top of ethereum blockchain.

Polygon solves pain points associated with Blockchains, like high gas fees and slow speeds, without sacrificing on security.

Ethereum blockchain has its own share of problems for Decentralized application developments(Dapps) such as

Poor UX
Low Throughput
No sovereignty (shared throughput/clogging risk, tech stack not customizable, governance dependence)

These problems introduces challenges and there is no framework to address these. So polygon was created as a protocol and a framework for building and connecting Ethereum-compatible blockchain networks.

MATIC is the native currency of the polygon ecosystem with ATH value of $2.62 dollars and market cap of $6 billion. More about the token performance is found here on coinmarketcap.

In this blog, let's learn how to configure polygon on metamask.

Before proceeding further, We need to create a metamask wallet. If you do not have one, create it by following this blog.

After you created, the wallet will look like below.

Click on the Ethereum mainnet at the top right corner and expand it. At the bottom, click on Custom RPC. Now you should see a screen just like below one.

Now, enter the below details for mainnet and Hit Save.

Polygon mainnet Settings

Network Name: Polygon Mainnet

New RPC URL: https://rpc-mainnet.maticvigil.com/

Chain ID: 137

Symbol: MATIC

Block Explorer URL: https://polygonscan.com/

Polygon Testnet Settings

Network Name: Polygon Mumbai

New RPC URL: https://rpc-mumbai.maticvigil.com/

Chain ID: 80001

Symbol: MATIC

Block Explorer URL: https://mumbai.polygonscan.com/

You can transfer BEP-20 MATIC to polygon network using binance. Otherwise, ERC-20 tokens will be transferred on Ethereum mainnet and BEP-20 tokens transferred on Binance smart chain.
