What are MetaMask Snaps?

Imagine transforming your MetaMask wallet into a hub of unlimited features and functionality. MetaMask Snaps make it possible. These custom plugins, or "Snaps," are akin to apps for your wallet, enhancing its capabilities in various ways. Snaps can unlock compatibility with additional blockchains, offer transaction insights, seamlessly integrate popular dApps, APIs and much more.

Examples of Snaps can include:

  • Transaction insights: Enhancing users' web3 journey with clearer transaction insights, empowering them to identify potential security concerns and malicious smart contracts before finalizing a transaction.
  • Interoperability: MetaMask Snaps broadens web3 usage to encompass non-EVM blockchains such as Bitcoin, Solana, Cosmos, and EVM Layer 2 solutions like StarkNet.
  • Notifications: Keeping users informed and engaged with web3-specific notifications, like the Wallet Guard Snap, directly in MetaMask, ensuring you never miss an essential update or event.

Snaps are new features and functionality, created by third-party developers, that MetaMask users worldwide can install directly into their wallet. Previously, MetaMask features were exclusively developed by MetaMask developers employed by Consensys. By providing users with a new set of tools developed by third-party developers across the globe, MetaMask Snaps will empower individuals to shape their web3 experience according to their unique needs and preferences.

Are MetaMask Snaps secure?

The implementation of Snaps was created with security at its core. Snaps run in a sandboxed environment in order to ensure that user assets and data can not be modified without permission. This prevents from unwanted interactions and scams by allowing users to have full control of what Snaps and permissions they choose to enable.
