A browser extension for browsers (i.e. Chrome, Brave) for interacting with distributed applications which require, by design, specific dapp browsers such as Ethereum Mist
Metamask is a cryptocurrency wallet which can be used on the Chrome, Firefox and Brave browsers. It’s also a browser extension. This means that it works like a bridge between normal browsers and the Ethereum blockchain.
The Ethereum blockchain is a network where users can build their own apps (which are called dApps) and cryptocurrencies. Ethereum also allows its users to write transaction guidelines called smart contracts. MetaMask can be used to store keys for Ethereum cryptocurrencies only.
So, the MetaMask wallet can be used for storing keys for Ether and ERC20 tokens on three different web browsers. It also allows users to browse the Ethereum blockchain from a standard browser. MetaMask requires no login and does not store your private keys in any server, instead they are stored on Chrome and password protected.
MetaMask is a dedicated way to allows you to run Ethereum Apps right in your browser without running a full Ethereum node. This wallet simplify the ethereum transactions. In Firefox browser you can download its extension and soon they will improve one for Google Chrome.
One of the core features of MetaMask is a secure identity vault, which lets you manage your identities on different sites and sign blockchain transactions.
The overall goal of MetaMask is simple:
“Our mission is to make Ethereum as easy to use for as many people as possible.”
