+
+Integrate **MetaMask Embedded Wallets** (formerly *Web3Auth*) to enable instant, secure, and seamless 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.  
+   🔗 [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 **Polygon**.  
+5. Save your configuration.
+
+✅ 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 seamlessly to **Polygon**.

+
+## **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.**
