Talking about MetaMask is one of the most reliable and well-recognized crypto wallets. The wallet is distinct from the other crypto wallets on the grounds that it majorly works for the Ethereum and ETH-supported tokens, unlike the other crypto assets. Calling spade a spade, the wallet bridges the gap between the Ethereum interface and the user. One of the functions of the wallet apart from storing and managing the crypto funds is to inject web3 (a javascript library) in the namespace of each of your browsers. This is just a briefing of the wallet. You might be now thinking of what the MetaMask extension is. Unlike a mobile app, an extension acts as an intermediary that connects the wallet and users operating through a computer/laptop. If you are a person who prefers to work through a web plugin, then you’ll need to get a supported extension first.
