MetaMask Embedded Wallets lets users sign in with familiar logins (Google, Apple, Discord, etc.) and instantly creates a **non-custodial wallet** connected to **Linea**. It’s fast, simple, and fully managed through the MetaMask Dashboard. ## 🌟 Why Use MetaMask Embedded Wallets on Linea? - **Instant onboarding:** Use OAuth providers like Google or Apple for quick user authentication - **Simple configuration:** Set up Linea once through the dashboard - **Non-custodial:** Users retain full control of their private keys - **Cross-platform support:** Works on web, mobile, and game engines - **Web2 - friendly UX:** Familiar login and onboarding flows ### Key Features - **External Wallet Aggregator:** Integrates SSO logins with existing crypto wallets (e.g. MetaMask), compatible with EVM and Solana. 🔗 [Docs](https://docs.metamask.io/embedded-wallets/features/external-wallets/) - **Flexible Authentication:** Supports Google, Facebook, X, passwordless email, and custom OAuth2.0, enabling frictionless Web2-to-Web3 onboarding. 🔗 [Docs](https://docs.metamask.io/embedded-wallets/dashboard/authentication/) - **Group Connections:** Link multiple SSOs using a shared unique ID (e.g. same email) so users can access the same wallet via different logins. 🔗 [Docs](https://docs.metamask.io/embedded-wallets/authentication/group-connections/) - **Wallet Pregeneration:** Create wallets pre-registration using unique identifiers (e.g. email) to pre-fund for airdrops or bonuses. 🔗 [Docs](https://docs.metamask.io/embedded-wallets/features/wallet-pregeneration/) - **Multi-Factor Authentication:** Enforce additional security layers like OTPs or secondary SSOs for sensitive use cases. 🔗 [Docs](https://docs.metamask.io/embedded-wallets/sdk/vue/advanced/mfa/) - **Cross-Platform SDKs:** Available for React, Vue, JavaScript, Android, iOS, React Native, Flutter, Unity, and Unreal—users access the same wallet across devices. - **Native Smart Accounts:** Enable gas sponsorships, batch/automated transactions, spending caps, and automatic paymaster/bundler setup (Infura + Pimlico). 🔗 [Docs](https://docs.metamask.io/embedded-wallets/features/smart-accounts/) - **UI Flexibility:** Choose between prebuilt white-labelled UI or headless SDK for full customization and brand control. 🔗 [Docs](https://docs.metamask.io/embedded-wallets/sdk/vue/advanced/wallet-services/) ## **⚙️ 1. Dashboard Configuration (No Code Required)** All setup happens inside the **MetaMask Embedded Wallets Dashboard** — no SDK changes or code edits are required. ### **🪄 Steps** 1. Go to the [MetaMask Embedded Wallets Dashboard](https://dashboard.web3auth.io/). 2. Select your project or create a new one. 3. Navigate to the **Chains** tab. 4. Search for **Linea**. 5. Save your configuration. ✅ Once enabled, all MetaMask Embedded Wallets SDKs (React, Vue, JavaScript) will automatically connect to **Linea** — **no code updates needed**. ## **💻 3. Multi-Platform SDKs** MetaMask Embedded Wallets supports every major developer environment — so your dApps, mobile apps, and games can all connect seamlessly to **Linea**. | Platform | SDK Documentation | | --- | --- | | **React** | [docs.metamask.io/embedded-wallets/sdk/react](https://docs.metamask.io/embedded-wallets/sdk/react) | | **Vue** | [docs.metamask.io/embedded-wallets/sdk/vue](https://docs.metamask.io/embedded-wallets/sdk/vue) | | **JavaScript** | [docs.metamask.io/embedded-wallets/sdk/js](https://docs.metamask.io/embedded-wallets/sdk/js) | | **Node.js** | [docs.metamask.io/embedded-wallets/sdk/node](https://docs.metamask.io/embedded-wallets/sdk/node) | | **Android** | [docs.metamask.io/embedded-wallets/sdk/android](https://docs.metamask.io/embedded-wallets/sdk/android) | | **iOS** | [docs.metamask.io/embedded-wallets/sdk/ios](https://docs.metamask.io/embedded-wallets/sdk/ios) | | **React Native** | [docs.metamask.io/embedded-wallets/sdk/react-native](https://docs.metamask.io/embedded-wallets/sdk/react-native) | | **Flutter** | [docs.metamask.io/embedded-wallets/sdk/flutter](https://docs.metamask.io/embedded-wallets/sdk/flutter) | | **Unity** | [docs.metamask.io/embedded-wallets/sdk/unity](https://docs.metamask.io/embedded-wallets/sdk/unity) | | **Unreal Engine** | [docs.metamask.io/embedded-wallets/sdk/unreal](https://docs.metamask.io/embedded-wallets/sdk/unreal) | ## **🔗 4. Connecting to Linea** After enabling **Linea** on the dashboard, MetaMask Embedded Wallets handles all connection logic automatically. ### **For JS based SDKs (React, Vue, JS & Node)** The wallet connects to **Linea** using the chain configuration you set in the dashboard. No developer setup required — the provider is pre-configured and ready to use. ### **For Mobile & Gaming SDKs (Android, iOS, Flutter, Unity, Unreal)** These SDKs expose a **user’s private key** securely. Developers can use it with their preferred blockchain library (e.g., `ethers.js`, `web3j`, or engine-native signing tools) to interact with **Linea** RPCs. **Navigate to the dedicated documentation for Linea on MetaMask Embedded Wallets docs.** ## **📚 Learn More** - **MetaMask Embedded Wallets Overview:** [docs.metamask.io/embedded-wallets](https://docs.metamask.io/embedded-wallets/) - **Linea Integration Guide:** [docs.metamask.io/embedded-wallets/connect-blockchain/evm/ethereum](https://docs.metamask.io/embedded-wallets/connect-blockchain/evm/linea) - **Dashboard Access:** [dashboard.web3auth.io](https://dashboard.web3auth.io/)
