-## 6. BigDecimal
-
-A custom `BigDecimal` implementation is used for precise numerical operations:
-
-- Use `BigDecimal` for all financial calculations to avoid floating-point errors
-- Implement utility functions that work with `BigDecimal` for common operations
-
-## 7. Custom Hooks
-
-Several custom hooks are used throughout the project:
-
-- Create hooks for reusable logic (e.g., `useChainId`, `useCurve`)
-- Implement hooks that combine multiple queries for complex data fetching scenarios
-
-Example:
-
-```typescript
-const { data: curve } = useCurve()
-```
