Install MetaMask Flask

MetaMask Flask is a canary distribution for developers that provides access to upcoming MetaMask features. Snaps is the first feature rolled out in the Flask environment.

Install Flask in a new browser profile, or disable any existing installed versions of MetaMask before installing Flask.

caution

Running multiple instances of MetaMask in the same browser profile breaks dapp interactions.
