Integrate WebSockets (Socket.io or native) to provide real-time updates for transaction statuses. UI should reflect on-chain confirmations and balancing changes without a manual page refresh.
- WebSocket connection established and managed.
- Real-time notifications for payment milestones.
- Graceful fallback to polling if WebSocket fails.
- State updates in React are efficient and atomized.
