Metamask was first released in 2016 by the Consen Sys, a blockchain software development company. The initial version was a browser extension for the Google Chrome browser, with support for Firefox and Brave browser added later. The goal of Metamask was to make it easier for users to interact with the Ethereum blockchain and decentralized applications (dApps) without the need for a separate software or hardware wallet.
In 2017, Metamask added support for Trezor and Ledger hardware wallets, allowing users to securely store their private keys on a hardware device.
In 2018, Metamask released its mobile wallet app, which allows users to access their wallet on their mobile devices, and also made it possible to use the wallet on other browsers.
In 2019, MetaMask introduced its version 4.0 which included a new design, a built-in token swap feature, and support for multiple accounts.
Today, Metamask is one of the most widely used digital wallets for Ethereum and other ERC-20 tokens, and continues to be developed and updated by Consen Sys to meet the evolving needs of its users.
