Description

Build a unified notification system that supports multiple channels (email via Nodemailer, SMS via Twilio, and push notifications) with user-configurable preferences.

Direction

1. Create notifications/ module with NestJS structure
2. Implement email templates and Nodemailer integration
3. Add Twilio SMS integration for critical alerts
4. Build WebSocket-based push notification system
5. Create user notification preferences UI/API
6. Add i18n support for multi-language notifications

Definition of Done

• All three notification channels are functional
• Users can configure which events trigger which channels
• Notifications are queued and retried on failure
• Notification history is stored and accessible to users
• Templates support localization for multiple languages

Acceptance Criteria

• ✅ Trade executions, liquidations, and deposits trigger appropriate notifications
• ✅ Users can opt in/out of specific notification types
• ✅ Failed notifications are retried with exponential backoff
• ✅ Notification delivery status is tracked
• ✅ All templates are available in English, Spanish, and Mandarin
