Mobile Integration TODO

Completed ✅

Phase 1: Core Infrastructure

  • ICN Context Provider with global state management
  • Trust Graph Visualization (D3.js force-directed)
  • Trust Attestation Form UI component
  • Offline storage with IndexedDB
  • Service worker with caching strategies
  • Sync manager for background operations

Phase 2: Push Notifications

  • Notification listener methods in ICNClient
  • useNotifications hook for React
  • WebSocket event definitions (TrustAttested, TrustRevoked, TransactionCompleted)
  • Trust API endpoints with event emission
  • Trust routes registered in gateway server

Phase 3: Trust Graph Integration

  • Trust API backend (attest, revoke, score, edges, network)
  • TrustManager with edge management
  • Trust events broadcast to personal DID channels
  • TrustGraph component wired to WebSocket updates
  • useTrustGraph and useTrustScore hooks

Remaining Work 🔄

1. Transaction Event Emission

Priority: HIGH Effort: 2 hours

The ledger operations need to emit TransactionCompleted events:

Files to modify:

  • icn/crates/icn-gateway/src/api/ledger.rs
  • icn/crates/icn-gateway/src/ledger_mgr.rs

Changes needed:

// In create_payment endpoint
let event = GatewayEvent::TransactionCompleted {
    coop_id: coop_id.clone(),
    hash: payment_hash,
    from: from_did.to_string(),
    to: to_did.to_string(),
    amount,
    currency: currency.clone(),
};
event_broadcaster.broadcast(&coop_id, event).await;

2. Conflict Resolution UI

Priority: MEDIUM Effort: 4 hours

When offline operations sync, conflicts may arise. Need UI to handle:

Files to create:

  • web/app/components/ConflictResolutionDialog.tsx
  • web/app/utils/conflictResolver.ts

Features:

  • Show conflicting operations side-by-side
  • Allow user to choose which to keep
  • Automatic resolution strategies (last-write-wins, merge)
  • Undo/redo support

3. Error Boundaries

Priority: MEDIUM Effort: 2 hours

Prevent component crashes from breaking the entire app:

Files to create:

  • web/app/components/ErrorBoundary.tsx

Features:

  • Catch React component errors
  • Display friendly error message
  • Log errors for debugging
  • Provide reset button

4. Native Push Notifications

Priority: MEDIUM Effort: 8 hours

For iOS/Android apps, integrate native push:

Files to modify:

  • web/app/utils/pushNotifications.ts (create)
  • FCM/APNs configuration

Features:

  • Request push permission
  • Register device token with gateway
  • Handle background notifications
  • Deep linking to relevant screens

5. Trust Recommendations

Priority: LOW Effort: 6 hours

Suggest trust attestations based on graph analysis:

Files to create:

  • web/app/components/TrustRecommendations.tsx
  • icn/crates/icn-gateway/src/api/trust_recommendations.rs

Algorithm:

  • Find mutual connections
  • Calculate trust transitivity
  • Rank by interaction frequency
  • Filter by trust threshold

6. Biometric Authentication

Priority: LOW Effort: 4 hours

Add fingerprint/Face ID for sensitive operations:

Files to create:

  • web/app/utils/biometric.ts

Features:

  • Detect biometric availability
  • Prompt for biometric auth before signing
  • Fallback to PIN/password
  • Secure keychain storage

7. Performance Monitoring

Priority: LOW Effort: 3 hours

Add Sentry or similar for production monitoring:

Files to modify:

  • web/app/App.tsx (add Sentry init)
  • web/app/utils/analytics.ts (create)

Metrics:

  • Error rates
  • API latency
  • WebSocket disconnects
  • User journey tracking

8. A/B Testing Framework

Priority: LOW Effort: 4 hours

Test different UI variations:

Files to create:

  • web/app/utils/experiments.ts
  • web/app/hooks/useExperiment.ts

Features:

  • Feature flags
  • Variant assignment
  • Metrics collection
  • Admin dashboard

Quick Wins (< 1 hour each)

  1. Add loading states to all async operations
  2. Add success animations for trust attestations
  3. Implement pull-to-refresh on mobile screens
  4. Add haptic feedback for button presses
  5. Add skeleton loaders for data fetching
  6. Improve accessibility (aria labels, screen reader support)
  7. Add keyboard shortcuts for power users
  8. Implement dark mode toggle
  9. Add connection quality indicator (WebSocket status)
  10. Create onboarding tutorial for first-time users

Testing Checklist

  • Test offline → online transition
  • Test WebSocket reconnection
  • Test trust attestation flow end-to-end
  • Test with 100+ trust graph nodes
  • Test on slow 3G connection
  • Test with poor network (packet loss)
  • Test memory usage over 24 hours
  • Test battery impact
  • Load test with 1000 notifications/sec
  • Security audit of API endpoints

Documentation Needs

  • API reference for trust endpoints
  • WebSocket event catalog
  • Mobile app user guide
  • Offline mode behavior documentation
  • Trust graph visualization guide
  • Deployment guide updates
  • Troubleshooting FAQ
  • Privacy policy for notifications

Deployment Preparation

  • Set up FCM project for push notifications
  • Configure APNs certificates
  • Set up CDN for static assets
  • Configure production WebSocket server
  • Set up monitoring (Sentry, Datadog)
  • Create CI/CD pipeline
  • Set up staging environment
  • Create rollback procedure
  • Load test with expected traffic
  • Security penetration testing
