MetaMask is a crypto wallet allowing users to store and access their crypto assets without depending on a centralized party or centralized exchange. MetaMask is a crypto wallet used to store Ether (the native token of Ethereum) or other ERC-20-based tokens. The wallet also serves other purposes such as interacting with other decentralized applications (dApps).
MetaMask serves as a gateway for the users into the world of decentralized finance (DeFi), Web 3.0, and Non-Fungible Tokens (NFTs). It is as simple as a browser plugin that can be easily installed on your personal computer like any other extension, serving primarily as an Ethereum wallet. Once installed, MetaMask lets the users interact with any Ethereum address and once it’s connected to Ethereum-based dApps, users can easily spend their coins on various games or can even trade them on several decentralized exchanges (DEXs).
Metamask can also be linked with several decentralized finance (DeFi) applications such as Compound.
