web3auth

Integrates MetaMask Embedded Wallets (Web3Auth) for non-custodial wallets via social login or custom JWT (Firebase, Auth0, Cognito). Use when integrating @web3auth/modal (React, Vue, Next.js, Vite, Angular), @web3auth/react-native-sdk (Expo/bare RN—Custom Dev Client, not Expo Go), web3auth_flutter, native Android/iOS, Unity, or @web3auth/node-sdk. Invoke for Sapphire devnet/mainnet, dashboard client ID, grouped connections (same address across Google + email passwordless), implicit vs JWT auth flows, useWeb3AuthConnect, id_token server-side verification, or SDK migration (web v11, RN v9, OPENLOGIN_NETWORK/LOGIN_PROVIDER legacy). Also use when users get different wallet addresses per login method or need RN Metro setup/withWeb3Auth migration. Do NOT use for MetaMask browser extension only, RainbowKit/ConnectKit without embedded wallets, or unrelated smart-contract work.
