Why Add Polygon (MATIC) Network to MetaMask?

There are a couple of reasons why you might want to add the Polygon (MATIC) network to MetaMask.

• Mint NFTs on OpenSea using the Polygon network (or other NFT marketplaces)
• Store, send and receive MATIC in MetaMask
• Use MetaMask Swaps to exchange MATIC for another token on DeFi apps such as UniSwap.

Aside from these, there are other reasons and benefits for adding the Polygon (MATIC) network to MetaMask, but we won’t be getting into further detail. Let’s see what are the ways of adding the Polygon (MATIC) network to MetaMask.

How to Add Polygon (MATIC) Network to MetaMask – Extension/Browser

If you are using your browser, there are two main ways to add Polygon (MATIC) network to your MetaMask wallet.

1. Using Polygonscan.
2. Manually through MetaMask.

1. Adding Polygon Network to MetaMask is very easy if you do it through the official Polygonscan website. Once you open the website, you will need to scroll down to the bottom of the webpage. In the bottom-right corner, you will see a button next to a MetaMask icon – “Add Polygon Network”. This will open a pop-up window in MetaMask, where you need to click “Confirm” and you’re done.

2. Adding Polygon Network through MetaMask is a bit longer of a process. First, you need to open your MetaMask browser extension. Click on the current Mainnet in the top-middle section. By default, this should say “Ethereum Mainnet”. This will open a drop-down menu, where you need to click on “Add Network”. Here, you need to manually enter the network name, RPC URL, Chain ID, currency symbol, and block explorer URL.

See the sections below for an in-depth guide on how to do both. We also have a section, where we help you add the Polygon (MATIC) network to MetaMask on mobile devices.

Add Polygon (MATIC) Network to MetaMask – Polygonscan

This section covers 3 simple steps on how to add Polygon (MATIC) to MetaMask through Polygonscan.

• Open Polygonscan
• Scroll down to the bottom of the website and click “Add Network”
• Confirm the action in MetaMask

1. Open Polygonscan

Open the Polygonscan official website.

Polygonscan is a Polygon blockchain explorer website where you can see addresses, Polygon-based tokens, transactions, and more. Additionally, Polygonscan is made by the same people that developed Etherescan.

Once you open the website, proceed with the next step in our guide.

2. Scroll Down to the Bottom & Click “Add Network”

Once you open Polygonscan, you must scroll down to the bottom of the website. In the bottom-right corner, you will see a MetaMask icon, next to which is a button “Add Polygon Network”.

Furthermore, before clicking on that, make sure you log in to your MetaMask wallet account.

Once you complete this step, you can proceed with the next one.

3. Confirm the Action in MetaMask Pop-Up

Because MetaMask wallet allows you to connect to different dApps using your browser, you will see a pop-up once you click on “Add Network”. Once that’s done, you will need to confirm the action twice before the network is added to your MetaMask wallet.

Additionally, do not worry if an error appears, as this is the case when adding any network to MetaMask.

Once that’s done, you will have the Polygon network added in MetaMask. Also, it will automatically switch to it once you add it.

About Polygon (MATIC)

Polygon is a Layer 2 scaling solution for Ethereum. It uses a technology called Plasma that enables Ethereum smart contracts to be transferred off-chain, allowing them to be processed much faster than on the main Ethereum network.

The network sits on top of the Ethereum blockchain and takes care of all the heavy lifting when it comes to processing transactions. This makes it much cheaper and faster to send transactions on Polygon than on Ethereum itself.

In addition, Polygon is also designed to be easily integrated with other Ethereum scaling solutions, such as Plasma and Optimism.

It is compatible with existing Ethereum wallets and dApps, making it easy to use. As a result, Polygon is quickly becoming the go-to solution for developers who want to build high-performance decentralized applications on Ethereum.

About MetaMask Wallet

MetaMask is a crypto wallet that comes in the form of a browser extension (Chrome, Firefox, Brave, and Edge) or a mobile application (iOS and Android). It is well-known for being the best software wallet for ERC-20 tokens. In fact, the wallet only supports Ethereum-based cryptocurrencies and NFTs.

Nowadays a lot of people use MetaMask to connect to different decentralized applications (dApps). Most notably, people connect their MetaMask to PancakeSwap. There, they exchange Ethereum, for example, for another cryptocurrency that is not available in other crypto exchanges.

It also is a simple entry point to the world of DeFi. DeFi stands for decentralized finances, which is a term used to describe companies that look to provide open, permissionless, interconnected financial services. These services are usually lending and borrowing crypto, as well as other crypto-oriented banking services.

Most NFT marketplaces such as OpenSea support MetaMask. At the beginning of the crypto boom back in 2021, MetaMask got the spotlight as the most popular and easy-to-use crypto wallet to buy NFTs.
