How to Connect Polygon to MetaMask

Polygon is an Ethereum-based Layer 2 scaling solution. That means Polygon runs a souped up version of Ethereum that is faster and cheaper than the original network. Polygon helps Ethereum handle more transactions by processing them on various new ‘side chains’.

This frees up some space on the Ethereum blockchain and is similar to multi-chain projects like Polkadot and Cosmos. All of the transactions on Polygon are bundled together, checked for validity, and then written to the Ethereum mainnet, which also provides Polygon with robust security and “blockchain integrity”.

MetaMask supports Ethereum and any other token developed on the Ethereum Blockchain (ERC20 tokens), such as Tether, USDC, DAI, and the Uniswap token. It is also possible to add specific tokens or Blockchains, even if they aren’t officially supported or immediately compatible. Read more about MetaMask here.

Step-by-Step Guide

This is a step-by-step guide on how to connect Polygon network to MetaMask. Read more! If you’ve already read our tutorial about how to add BSC to MetaMask then this tutorial is a breeze for you!

The first way to connect the Polygon network to MetaMask is very simple, you just need to go to the SushiSwap website and Click Enter App:

On the top right corner, you see Connect to a wallet, click on it:

Click on MetaMask:

Choose Next:

Click Connect:.

Now we’re logged in to the Ethereum network. The trick here is when you click on the Ethereum symbol you can switch to different network options.

Select Polygon Matic:

Then the MetaMask will open up, click Approve and then select Switch network:

So automatically we switched from the Ethereum network to the Polygon network!The second way to connect Polygon network to MetaMask is typing information manually. Open your MetaMask wallet and head across to the circle icon in the top right.

Go to the Settings page:

Select Networks:

Then click Add network in the top right corner.

Here is where you’ll need to add some parameters. Below are the parameters to fill in for each.

Network Name: Polygon Mainnet

New RPC URL: https://polygon-rpc.com/

ChainID: 137

Symbol: MATIC

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

Once you click on Save and return to the main page you’ll notice two things: The network has changed to the Polygon network and the units are denominated in MATIC. MATIC is the native token on the Polygon network. If you’ve done everything right, then your wallet main page will look like this.

I hope that you have learned how to add Polygon network to MetaMask wallet after reading this article!
