+**Add account deletion support when unlinking profiles**
+
+Added optional `allowAccountDeletion` parameter to `useUnlinkProfile` hook and `unlinkProfile` function. When set to `true`, this allows deleting the entire account when unlinking the last profile associated with it.
+
+**React Hook Example:**
+
+```tsx
+import { useUnlinkProfile } from "thirdweb/react";
+
+const { mutate: unlinkProfile } = useUnlinkProfile();
+
+const handleUnlink = () => {
+  unlinkProfile({
+    client,
+    profileToUnlink: connectedProfiles[0],
+    allowAccountDeletion: true, // Delete account if last profile
+  });
+};
+```
+
+**Direct Function Example:**
+
+```ts
+import { unlinkProfile } from "thirdweb/wallets/in-app";
+
+const updatedProfiles = await unlinkProfile({
+  client,
+  profileToUnlink: profiles[0],
+  allowAccountDeletion: true, // Delete account if last profile
+});
+```
