MetaMask Definition
MetaMask is a browser extension, primarily for Google Chrome, Firefox, and the Brave browser, and a mobile application that functions as an Ethereum wallet. It interacts with Ethereum-based decentralized applications (dApps) directly from a web browser. It also provides a user interface to manage your identities on different sites and to sign blockchain transactions.
MetaMask Key Points
- MetaMask is a bridge that allows web browsers to interact with the Ethereum blockchain.
- It is both a wallet for Ether and Ethereum-based tokens, and an interface for dApps.
- It enables users to manage personal keys and identities, sign blockchain transactions, and securely store and send Ether.
- MetaMask is not only a browser extension available for Chrome, Firefox, and the Brave browser, but also a mobile application.
What is MetaMask?
MetaMask is an essential tool for those who interact with dApps, or utilize Ethereum and its related tokens. Rather than running a full Ethereum node, MetaMask connects to an Ethereum client, therefore users don’t need to download the entire Ethereum blockchain.
Why MetaMask is used?
MetaMask is used because it’s a simple and secure way to interact with the Ethereum network. Its security features include vault encryption, secure login, and key pair generation. Its simplicity comes from being a lightweight, easy-to-use browser extension. MetaMask allows users to interact with the world of Ethereum directly from their browser without running a full Ethereum node.
Who uses MetaMask?
MetaMask is used by Ethereum enthusiasts, developers, and anyone who wants to interact with Ethereum’s decentralized applications or send and receive ETH.
Where can MetaMask be used?
As a browser extension, MetaMask can be used on any device that supports Google Chrome, Firefox, or the Brave browser. In addition, since it’s also a mobile application, it can be used on any iOS or Android device.
When was MetaMask created?
MetaMask was created by Dan Finlay, and team in 2016. As Ethereum and its ecosystem have grown, so too has the use of MetaMask become more prevalent.
How does MetaMask work?
MetaMask functions by injecting a javascript library called web3.js into the namespace of each page your browser loads. This allows each page to communicate with the Ethereum blockchain. It generates passwords and keys on your device, so only you have access to your accounts and data. It never sends your keys or data off your machine. Instead, it performs all necessary operations right there on your device, which forms the crux of its security.
