What is Metamask Wallet?

Metamask is a cryptocurrency wallet used as an extension on Chrome, Firefox and Brave browsers, allowing you to manage your Ethereum private keys through a web browser.

It allows running Ethereum dApps (Decentralized Applications) right in the browser without running a full Ethereum node. This means you don't have to download and sync the entire blockchain on your device or computer. Instead, the computer connects to another Ethereum Node called infra and runs smart contracts on that Node.
