MetaMask is a software cryptocurrency wallet used to interact with the 以太坊 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英语software company focusing on Ethereum-based tools and infrastructure.[3][4]

Overview[编辑]

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] Developers achieve a connection between Metamask and their decentralized applications by using a JavaScript plugin such as Web3js or Ethers to define interactions between Metamask and Smart Contracts.

The Metamask 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]

截至2021年11月 (2021-11), MetaMask's browser extension had over 21 million monthly active users, according to Bloomberg.[8]

History[编辑]

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]

In 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[编辑]

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英语Personal identifier to data collection networks and web trackers英语Web tracking as a fundamental flaw.[3][13]
