+Added new `SiteEmbed` React component for embedding thirdweb-supported sites with seamless wallet connection support.
+
+The component allows you to embed other thirdweb-enabled sites while maintaining wallet connection state, supporting both in-app and ecosystem wallets.
+
+Example usage:
+```tsx
+import { SiteEmbed } from "thirdweb/react";
+
+<SiteEmbed 
+  src="https://thirdweb.com" 
+  client={client}
+  ecosystem={ecosystem}
+/>
+```
+
+Note: Embedded sites must include `<AutoConnect />` and support frame-ancestors in their Content Security Policy.
