Please view the third-party content disclaimer [here](https://github.com/0xPolygon/polygon-docs/blob/main/CONTENT_DISCLAIMER.md). Integrate **MetaMask Embedded Wallets** (formerly *Web3Auth*) to enable instant, secure wallet onboarding for your users on **Polygon**, with **no additional code** required. MetaMask Embedded Wallets lets users sign in with familiar logins (Google, Apple, Discord, etc.) and instantly creates a **non-custodial wallet** connected to **Polygon**.\ It’s fast, simple, and fully managed through the MetaMask Dashboard. ## Why Use MetaMask Embedded Wallets on Polygon? * **Instant onboarding:** Use OAuth providers like Google or Apple for quick user authentication * **Simple configuration:** Set up Polygon 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.\ πŸ”— [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.\ πŸ”— [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.\ πŸ”— [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.\ πŸ”— [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.\ πŸ”— [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).\ πŸ”— [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.\ πŸ”— [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 **Polygon**. 5. Save your configuration. βœ… Once enabled, all MetaMask Embedded Wallets SDKs (React, Vue, JavaScript) will automatically connect to **Polygon**. **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 to **Polygon**. | 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 Polygon** After enabling **Polygon** on the dashboard, MetaMask Embedded Wallets handles all connection logic automatically. ### **For JS based SDKs (React, Vue, JS & Node)** The wallet connects to **Polygon** 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 **Polygon** RPCs. **Navigate to the dedicated documentation for Polygon on MetaMask Embedded Wallets docs.** ## **Learn More** * **MetaMask Embedded Wallets Overview:** [docs.metamask.io/embedded-wallets](https://docs.metamask.io/embedded-wallets/) * **Polygon Integration Guide:** [docs.metamask.io/embedded-wallets/connect-blockchain/evm/polygon](https://docs.metamask.io/embedded-wallets/connect-blockchain/evm/polygon) * **Dashboard Access:** [dashboard.web3auth.io](https://dashboard.web3auth.io/)
