MetaMask is a software cryptocurrency wallet used to interact with the Ethereum
blockchain. It allows users to access their Ethereum wallet through a browser
extension or mobile app, which can then be used to interact with decentralized
applications.[1][2] MetaMask is developed by ConsenSys Software Inc., a
blockchain software company focusing on Ethereum-based tools and
infrastructure.[3][4]

OVERVIEW

MetaMask allows users to store and manage account keys, broadcast transactions,
send and receive Ethereum-based cryptocurrencies and tokens, and securely
connect to decentralized applications through a compatible web browser or the
mobile app's built-in browser.[5][6]

Websites or other decentralized applications are able to connect, authenticate,
and/or integrate other smart contract functionality with a user's MetaMask
wallet (and any other similar blockchain wallet browser extensions) via
JavaScript code that allows the website to send action prompts, signature
requests, or transaction requests to the user through MetaMask as an
intermediary.[citation needed]

The application includes an integrated service for exchanging Ethereum tokens by
aggregating several decentralized exchanges (DEXs) to find the best exchange
rate. This feature, branded as MetaMask Swaps, charges a service fee of 0.875%
of the transaction amount.[7]

As of November 2021, MetaMask's browser extension had over 21 million monthly
active users, according to Bloomberg.[8]

HISTORY

MetaMask was created by ConsenSys in 2016.[3]

Prior to 2019, MetaMask had only been available as a desktop browser extension
for Google Chrome and Firefox browsers. Given the popularity of MetaMask among
cryptocurrency users, and its lack of an official mobile app for several years,
instances of malicious software posing as MetaMask became problematic for Google
in regulating its Chrome Web Store and Google Play platforms.[9][10][11] In one
instance, Google Play unintentionally removed MetaMask's official beta app
before reverting the decision a week later on January 1, 2020.[12]

Starting in 2019, MetaMask began releasing mobile app versions for closed beta
testing, followed by their official public release for iOS and Android in
September 2020.[2][5]

During October 2020, MetaMask Swaps, a built-in DEX aggregation service was
added to the desktop extension. The product became available on mobile devices
in March 2021.[7]

CRITICISM

While MetaMask and other "Web3" focused applications aim to decentralize control
over personal data and increase user privacy, critics have pointed to the
potential for MetaMask's browser extension to leak identifiable information to
data collection networks and web trackers as a fundamental flaw.
