MetaMask is one of the most popular browser extensions that serve as a way of storing your Ethereum and other Network Tokens. The extension is free and secure, and it allows web applications to read and interact with Ethereum’s blockchain. With Ethereum came the promise of a distributed Internet – the long-awaited Web 3.0. A level playing field characterized by a lack of central points of failure, true ownership of data, and decentralized applications (or DApps). Such an infrastructure is steadily coming together with an industry-wide focus on Decentralized Finance (DeFi) and interoperability protocols that aim to bridge the various blockchains. It’s now possible to trustlessly exchange tokens and cryptocurrencies, take out crypto-backed loans, and even use Bitcoin on Ethereum. For many Ethereum enthusiasts, MetaMask is the go-to wallet. Unlike your regular smartphone or desktop software, it comes packaged as a browser extension, allowing users to directly interact with supporting webpages. In this article, we’ll explain how MetaMask works and walk you through getting started with it yourself.
