MetaMask

MetaMask Definition

MetaMask is a web browser extension that functions as a cryptocurrency wallet. It connects to Ethereum blockchain, allowing users to interact with Ethereum’s ecosystem, including its decentralized applications (dApps) directly from the browser. It is a bridge that allows you to visit the distributed web of tomorrow in your browser today.

MetaMask Key Points

  • 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 interact with Ethereum dApps.
  • MetaMask also serves as a fully functional Ethereum wallet: its users can store and send any ERC20 tokens.
  • It is known for its user-friendly interface, making it easy for users to navigate and understand.

What is MetaMask?

MetaMask is a browser extension that allows you to run Ethereum dApps right in your browser without running a full Ethereum node. It includes a secure identity vault, providing a user interface to manage your identities on different sites and sign blockchain transactions. It also allows you to create and manage your own identities (or ‘keys’), so when a dApp wants to perform a transaction and write to the blockchain, it asks you to approve that transaction.

Why is MetaMask important?

MetaMask is important because it brings Ethereum to your browser. This means that it allows anyone to easily access and interact with the Ethereum blockchain and its dApps, which are otherwise not so user-friendly. It also provides a secure and manageable identity vault which is a big step towards making Ethereum user-friendly and accessible to the mainstream.

Where can you use MetaMask?

MetaMask can be used on Google Chrome, Firefox, and Brave browsers. It is also available as a mobile app on both iOS and Android. It is mainly used to interact with dApps on the Ethereum blockchain.

When was MetaMask created?

MetaMask was created in 2016 by Aaron Davis and the team at ConsenSys, a blockchain software technology company.

Who uses MetaMask?

MetaMask is used by people who want to interact with the Ethereum blockchain and its dApps. This includes both developers who are building these dApps and users who want to use them.

How does MetaMask work?

MetaMask works by injecting a javascript library called web3.js into the namespace of each page your browser loads. This allows each page to interact with the Ethereum blockchain. It also securely stores your Ethereum addresses and their private keys, allowing you to sign transactions without exposing your keys.
