MetaMask adds Ethereum to any website, enabling you to use Ethereum in any application without requiring shoppers to install a
MetaMask Chrome extension. Users can pay for products and services via cryptocurrency and make in-app payments without having to leave the app.
The
MetaMask Extension is the user’s gateway to Ethereum powered websites. It allows the user to access existing accounts or create new ones, search for addresses and send Ether directly from their browser.
