Install Snaps

To install Snaps, you must install the MetaMask Flask browser extension.

Prerequisites​

  • Up-to-date Chromium or Firefox browser
  • Node.js version 16 or later
  • Yarn version 3

Install the MetaMask Flask browser extension​

MetaMask Flask is an experimental playground that provides developers access to upcoming MetaMask features. It is available as a browser extension.

Snaps is the first feature rolled out in the Flask environment.

Install in a new browser profile

Install the Metamask Flask browser extension in a new browser profile, or disable any existing installed versions of MetaMask before installing Flask. Running multiple instances of MetaMask in the same browser profile breaks dapp interactions.
