Aptos Snap is the application allowing users to directly manage Aptos within the MetaMask interface. Since Snaps is pre-release software, the alpha version of Aptos Snap is currently live on Metamask Flask only, a canary distribution for developers that provides access to upcoming features.
*Note: MetaMask Flask is an experimental playground for developers and is not to be confused with the normal MetaMask wallet app.
Snaps is a system that allows developers to safely build and expand the capabilities of MetaMask. It is a program that is run in an isolated environment with a limited set of capabilities, that can customize and modify MetaMask's wallet experience for end users. For example, a snap can add new APIs to MetaMask thus adding support for different blockchains or modify existing functionalities using internal APIs.
