What is MetaMask Snaps? Main Functions & Features Explained

MetaMask is a popular cryptocurrency wallet and browser extension that allows users to interact with decentralized applications (dApps) on the Ethereum blockchain. It provides a secure and convenient way to manage digital assets, interact with smart contracts, and explore the world of decentralized finance (DeFi). In recent years, MetaMask has introduced a new feature called MetaMask Snaps, which further enhances its functionality and opens up new possibilities for developers and users alike.

Understanding MetaMask Snaps

MetaMask Snaps is an extension framework that allows developers to create and integrate custom plugins, or “snaps,” into the MetaMask wallet. These snaps can extend the functionality of MetaMask by adding new features, integrating with external services, or providing alternative user interfaces. Snaps are essentially mini-applications that can be installed and used within the MetaMask wallet, enhancing the user experience and enabling new use cases.

Snaps are built using web technologies such as HTML, CSS, and JavaScript, making it easy for developers to create and deploy them. They can interact with the Ethereum blockchain, access user accounts and balances, and perform various operations on behalf of the user. Snaps can be developed by anyone, including individual developers, startups, or established companies, and can be distributed through the MetaMask Snaps Marketplace.

Main Functions of MetaMask Snaps

MetaMask Snaps offer a wide range of functions and features that can enhance the user experience and provide new capabilities. Some of the main functions of MetaMask Snaps include:

  • Custom Wallet Integrations: Snaps can integrate with external wallets and services, allowing users to manage their digital assets across different platforms. For example, a snap could enable users to connect their MetaMask wallet with a hardware wallet for enhanced security.
  • Alternative User Interfaces: Snaps can provide alternative user interfaces for interacting with dApps. This allows developers to create specialized interfaces tailored to specific use cases or industries. For example, a snap could provide a user-friendly interface for decentralized exchanges or lending platforms.
  • Additional Security Features: Snaps can add extra layers of security to the MetaMask wallet. For example, a snap could implement multi-factor authentication or biometric authentication for accessing the wallet.
  • Integration with External Services: Snaps can integrate with external services and APIs, enabling users to access additional features and functionalities. For example, a snap could integrate with a decentralized identity service to provide seamless login and authentication.
  • Enhanced Privacy: Snaps can enhance privacy by implementing features such as coin mixing or privacy-preserving transactions. These features allow users to transact on the Ethereum blockchain without revealing their identities or transaction details.

Benefits of MetaMask Snaps

MetaMask Snaps offer several benefits for both developers and users:

  • Flexibility: Snaps provide developers with the flexibility to extend the functionality of MetaMask and create innovative solutions. They can build custom interfaces, integrate with external services, and experiment with new features.
  • Improved User Experience: Snaps enhance the user experience by providing alternative interfaces and additional features. Users can choose the snaps that best suit their needs and preferences, making their interaction with dApps more seamless and enjoyable.
  • Increased Security: Snaps can add extra layers of security to the MetaMask wallet, protecting users’ digital assets and personal information. Developers can implement advanced security features, such as hardware wallet integration or biometric authentication, to enhance the overall security of the wallet.
  • Expanded Use Cases: Snaps enable new use cases and functionalities that were not previously possible with MetaMask alone. Developers can create specialized snaps for specific industries or applications, opening up new opportunities for innovation and adoption.
  • Community-driven Development: The MetaMask Snaps framework encourages community-driven development, allowing developers to contribute their own snaps and share them with the wider community. This fosters collaboration and innovation within the ecosystem.

Examples of MetaMask Snaps

Several snaps have already been developed and are available for users to install and use within the MetaMask wallet. Here are a few examples:

  • Uniswap Snap: This snap provides a user-friendly interface for interacting with the Uniswap decentralized exchange. Users can easily swap tokens, provide liquidity, and explore the various pools available on Uniswap.
  • Aave Snap: The Aave snap allows users to access the Aave lending platform directly from the MetaMask wallet. Users can lend or borrow assets, earn interest, and manage their positions on Aave.
  • ENS Snap: This snap integrates with the Ethereum Name Service (ENS) and provides a seamless experience for managing ENS domains. Users can register, transfer, and update their ENS domains without leaving the MetaMask wallet.


MetaMask Snaps is a powerful extension framework that enhances the functionality of the MetaMask wallet and opens up new possibilities for developers and users. Snaps allow developers to create custom plugins that extend the wallet’s capabilities, providing alternative interfaces, integrating with external services, and adding extra layers of security. Users can choose the snaps that best suit their needs, enhancing their experience with decentralized applications and expanding the use cases of MetaMask. With the growing adoption of decentralized finance and the increasing demand for user-friendly interfaces, MetaMask Snaps play a crucial role in driving innovation and improving the overall user experience in the blockchain ecosystem.
