Easy and straightforward. Now, let’s get deeper.

What is A MetaMask Snap?

A MetaMask Snap is like a mini-app that you can add to your MetaMask wallet to expand its functionality and capabilities. Imagine it as a Lego brick that you can snap onto your MetaMask wallet to unlock new features and possibilities.

Snaps are designed to be secure and user-friendly, but it’s still important to be cautious and only install Snaps from trusted developers. You can browse and install MetaMask approved Snaps directly from the MetaMask extension website. Each Snap has its own permissions, so you’ll always be able to see what data it can access before you install it. Once you install a Snap, you can use it directly within your MetaMask wallet.
