### Note on Loan Application
The loan application endpoint was not found in the current codebase as it appears to be a view-only function. If loan applications are processed through:
- A separate API endpoint
- A form submission to another controller
- A JavaScript handler

Please provide those details and we can add notifications accordingly.

## Implementation Details

### Admin Email Detection
The system automatically retrieves the admin email in this order:
1. **ADMIN_EMAIL environment variable** (recommended)
2. **First admin in database** (fallback)
3. **mail.from.address configuration** (final fallback)

### Error Handling
All email operations are wrapped in try-catch blocks:
- Success logged with `Log::info()`
- Errors logged with `Log::error()`
- Email failures don't break transaction (non-blocking)

### Data Included in Each Notification
Every notification includes:
- User information (name, username, email, phone, country, current balance)
- Action-specific details
- Action type with emoji and color
- Admin action guidelines
- Direct link to admin panel
- Timestamp of notification

## Features

✅ **Dynamic Subject Lines** - Based on action type
✅ **Color-Coded Emails** - Each action has unique color/icon
✅ **Automatic Admin Detection** - Multiple fallback methods
✅ **Comprehensive Logging** - Debug information for all operations
✅ **Non-Blocking** - Email failures don't disrupt transactions
✅ **Mobile-Responsive** - Works on all devices
✅ **Secure** - No sensitive data exposed
✅ **Reusable** - Single mail class for all actions
✅ **Database Notifications** - Also creates DB records where applicable
✅ **Amount Formatting** - Displays monetary values with proper formatting

## Configuration

### Environment Variables
Add to `.env` file:
```env
ADMIN_EMAIL=admin@example.com
```

### Mail Configuration
Ensure mail settings are configured in `config/mail.php`:
```php
'from' => [
    'address' => env('MAIL_FROM_ADDRESS', 'noreply@example.com'),
    'name' => env('MAIL_FROM_NAME', 'App Name'),
],
```

## Testing

### To Test Admin Notifications:
1. Register a new user or log in as existing user
2. Perform any of the tracked actions:
   - Purchase a signal
   - Copy an expert trader
   - Invest in a plan
   - Invest in AI bot
   - Update password/profile
   - Make a deposit
   - Upload KYC documents
   - Make a withdrawal
3. Check admin email for notification
4. Check Laravel logs at `storage/logs/laravel.log` for confirmation

### Log Entries to Look For:
- `Admin notification sent for [action] by: [username]`
- `Failed to send admin [action] notification: [error message]`

## Security Considerations

⚠️ **Important:**
- Admin email is never exposed in user-facing emails
- Only admin receives these notifications
- All transaction amounts are validated server-side
- Timestamps use server time (not client-provided)
- Error messages are logged but not exposed to users

## Future Enhancements

Possible future improvements:
- [ ] Add email templates for each specific action (currently uses generic template)
- [ ] Add SMS notifications to admin
- [ ] Add dashboard widget showing real-time notifications
- [ ] Add email digest (daily/weekly summary)
- [ ] Add notification preferences for admin
- [ ] Add webhook support for external notifications
- [ ] Add filtering by transaction amount
- [ ] Add user risk scoring based on actions
