Optimize performance and implement caching strategies

[gboigwe]

Description

Implement performance optimizations and caching strategies throughout the application.

Optimization Areas

Frontend Performance

• Code splitting
• Image optimization
• Lazy loading components
• Bundle size optimization

Caching Strategy

// TanStack Query caching
const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      staleTime: 5 * 60 * 1000, // 5 minutes
      cacheTime: 10 * 60 * 1000, // 10 minutes
      refetchOnWindowFocus: false,
    },
  },
});

Contract Call Optimization

• Batch read-only calls
• Cache contract data
• Optimize transaction gas costs

Acceptance Criteria

• Lighthouse score >90
• Bundle size optimized
• Images optimized
• Code splitting implemented
• Caching strategy documented
• Contract calls minimized

Dependencies

• All issues

Estimated Complexity

Medium
