What are Embedded Wallets?

MetaMask Embedded Wallets (formerly Web3Auth) provides a pluggable embedded wallet infrastructure to simplify Web3 wallet integration and user onboarding. It supports OAuth-based logins and multiple platforms, allowing your users to access Web3 applications through familiar authentication methods.

MetaMask Embedded Wallets reduces traditional wallet management overhead by removing the need to manage private keys and seed phrases directly.

End-user steps: traditional standalone wallet versus Embedded Wallets

Users get a smoother onboarding experience while retaining control of non-custodial wallets.

  • Use a drop-in solution that works with your existing auth system.
  • Avoid complex migrations or infrastructure changes.
  • Customize the look and feel.
  • Integrate on web, mobile, and gaming platforms.

User experience​

Provide a low-friction path to Web3:

  • Help users get started quickly.
  • Avoid requiring users to understand blockchain concepts up front.
  • Let users own and control their wallets.
  • Support account recovery flows.

MetaMask Embedded Wallets provides wallet infrastructure for dapps and blockchain wallets. This documentation explains how it works, including how it generates cryptographic key providers for each user and application.

How do Embedded Wallets work?​

See Architecture for the high-level system design, SDK and integration diagram, and wallet management infrastructure.

Is MetaMask Embedded Wallets a wallet?​

MetaMask Embedded Wallets is not a wallet, but rather a wallet infrastructure that can be integrated into any application. It provides customizable authentication flows for dapps and blockchain wallets, solving user onboarding and key management challenges.

Unlike traditional wallets that can limit user experience, MetaMask Embedded Wallets enables developers to create tailored flows without requiring users to understand complex blockchain concepts. It provides a cryptographic key provider that can be used to build custom wallets or integrate with existing ones through Web3Auth's external wallet adapters.

Is MetaMask Embedded Wallets scalable?​

The MetaMask Embedded Wallets infrastructure is built to handle millions of users. Our architecture provides:

  • Global availability across multiple regions with consistent low-latency performance worldwide
  • Automatic horizontal scaling that adjusts capacity based on demand, eliminating bottlenecks and ensuring uninterrupted service
  • Enterprise-grade infrastructure running on Kubernetes orchestration for maximum reliability and performance
