What Is MetaMask?
MetaMask is a software cryptocurrency wallet used to interact with the Ethereum blockchain. It can be accessed via a browser extension or mobile app. Developed by ConsenSys Software Inc., a company specializing in Ethereum-based tools and infrastructure, MetaMask is a key tool for engaging with decentralized applications (dApps).
Background
MetaMask was created by ConsenSys in 2016 and has quickly grown in popularity. As of November 2021, it boasts over 21 million monthly active users. Initially only available as a desktop browser extension, MetaMask has expanded its offerings to include a mobile app released in September 2020.
How It Works
MetaMask stores and manages account keys, broadcasts transactions, sends and receives Ethereum-based cryptocurrencies and tokens, and connects securely to dApps. Websites or other dApps can interact with a user’s MetaMask wallet via JavaScript, enabling the website to send action prompts, signature requests, or transaction requests to the user. MetaMask also includes an integrated service, MetaMask Swaps, for exchanging Ethereum tokens by aggregating several decentralized exchanges (DEXs) to find the best exchange rate.
