MetaMask Embedded Wallets (Web3Auth)

MetaMask Embedded Wallets (formerly Web3Auth) is a pluggable wallet infrastructure that brings non-custodial social login wallets to any application. Users authenticate with familiar OAuth providers — Google, X, Discord, GitHub, and more — and get a secure, recoverable wallet without ever seeing a seed phrase.

  • Non-custodial by design — private keys are split across multiple parties using Shamir Secret Sharing and MPC. No single party, including MetaMask, ever holds the full key.
  • Chain-agnostic — built-in providers for EVM and Solana; export the private key for any other chain.
  • Every platform — Web, React Native, Android, iOS, Flutter, Unity, Unreal, and Node.js.
