MetaMask is a prominent crypto wallet with a huge cohort of users. It allows them to easily navigate through various networks, including Polygon. Today, we are going to discover how to add Polygon to MetaMask.

Introduction to MetaMask and Polygon Network

It is crucial to know how to use crypto tools that provide market participants with access to the whole perks of digital assets. MetaMask and Polygon Network are one of them.

What is MetaMask?

MetaMask is one of the most popular Web3 wallets operating on Ethereum and other compatible blockchains directly from a browser. It serves as a gateway to the world of decentralized applications (dApps), enabling users to manage cryptocurrencies and access various services seamlessly.

Developers revealed MetaMask in the browser and mobile app version (Android and iOS). You can download your perfect one from its official website.

What is Polygon Network?

Polygon, previously known as Matic Network, is a Layer 2 solution for Ethereum. It aims to address Ethereum's scalability issues by providing a framework for building and connecting multiple blockchain networks. Polygon is faster and cheaper than Ethereum. All the features are making it an attractive option for developers and users.

Here are some Polygon numbers, according to DappRadar:

  • total UAW (Unique Active Wallets) – 225,7M;
  • conducted transactions – 777,71M;
  • dApps volume – $1,57T.

Scroll down to the bottom of the page and click on "Add Network". The wallet will provide you a list of popular networks with Polygon in it. Push "Add" in front of the name of the network you are interested in.
