Metamask is a browser extension that allows you to interact with the Ethereum blockchain, all without downloading the entire data-filled blockchain. It’s a simple tool that allows you to use your cryptocurrency, all in your regular web browser. This will help more people access and use Ethereum dApps, without the technical know-how or need to download the whole blockchain and run a full node.
Metamask also functions as a web-based software wallet, so you can store your crypto here, but be aware that it is a ‘hot wallet‘ and it is risky to keep it here (read more about software wallets on our essential guide page).
Our video runs through the Metamask browser extension, and shows you how to set up and use certain features.
