This article will show you how to add Polygon (Matic) to MetaMask and make it the only wallet that you need on your computer.

What is Metamask?

Metamask is an ethereum browser. It allows you to interact with smart contracts and decentralized applications on the Ethereum network. It is not just a wallet, but also a tool that sits between you and your smart contract or DApp.

To discuss what metamask is and its purpose, we need to understand some of the basics about Ethereum.

Ethereum was created by Vitalik Buterin in 2013 as a way to create a less trustless environment for people to build applications on top of the blockchain. You can think of it as an operating system for the blockchain: it provides the basic tools needed to run applications like computer programs and websites, but also gives developers access to some powerful functionality like decentralization.

The reason why Ethereum has become so popular is because it gives developers access to all this power without having to deal with any intermediaries or bureaucracies. This makes it ideal for building decentralized applications that are censorship resistant and secure against attacks from hackers or governments who want to shut down their operations.

Metamask comes also as a Chrome extension that allows you to run Ethereum dApps. You can find it at and it is totally free. The MetaMask extension allows users to interact with their accounts through an interface built into their browser (Chrome, Firefox, Brave). Users are also able to create new accounts and send/receive ETH/ERC20 tokens without having to download a full copy of the blockchain onto their computer.

Metamask is a standalone browser wallet that allows users to access their wallets in their web browsers. It also has an integrated wallet built into it, which allows users to manage their private keys offline. The main aim of Metamask is to provide an easy-to-use interface for people who want to use Ethereum based tokens, smart contracts and DApps.

Metamask wallet in contrast is the most popular open-sourced non-custodial wallet in the crypto space. It is used by millions of cryptocurrency investors across multiple operating systems to purchase, store, and trade cryptocurrencies and other digital assets with ease.

What is Polygon?

Polygon is a Layer 2 scaling solution that focuses on reducing the complexity of scalability and instant blockchain transactions. It boasts of up to 65,000 transactions per second on a single side chain, along with a respectable block confirmation time of less than two seconds.

Polygon is a decentralized, fully-decentralized and distributed cryptocurrency. Polygon is an open source project that uses the latest developments in cryptography to create a cryptocurrency that is uncensorable, transparent and secure.

The Polygon network enables users to send encrypted messages to each other as well as make payments using a simple QR code scan. The payment system is entirely decentralized and peer-to-peer without any intermediaries or third parties involved in it.

Polygon’s blockchain technology allows for instant transactions, state of the art encryption, privacy and security. The protocol also allows for the creation of custom tokens on top of its platform which can be used to reward users or incentivize them to participate in the network.

Polygon provides a standard interface for developers to build decentralized applications with Web3 and ethereum. Polygon enables developers to create decentralized applications (DApps) that are easy to use and understand, while providing them with the full power of ethereum.

Polygon allows you to create your own contracts with any level of complexity. The best part is that it’s written in Javascript so you can interact directly with the Ethereum network.

Launched in October 2017, Polygon was co-founded by Jaynti Kanani, Sandeep Nailwal and Anurag Arjun
