Web3Auth (now MetaMask Embedded Wallets) is a non-custodial threshold-key wallet and authentication platform. It provides client SDKs (Web, React, Vue, iOS, Android, Flutter, React Native, Unity, Unreal, Node.js) and a backend Auth Network for OAuth-anchored MPC key shares. Public HTTP surface is limited and SDK-first.
