The changes follow industry best practices and establish a more robust foundation for the escrow functionality. + +#### Key Improvements + +##### Architecture & Organization +- Separated concerns between types, services, and state management +- Moved shared types to centralized `@types` directory +- Established clear boundaries between data layer and business logic +- Improved code organization following domain-driven design principles + +##### Type Safety +- Consolidated duplicate type definitions +- Enhanced type definitions using TypeScript utility types (Omit, Pick) +- Improved type consistency for numeric values stored as strings +- Added proper type imports with explicit 'type' imports + +##### Performance Optimizations +- Implemented proper function memoization using useCallback +- Fixed React hooks dependency arrays +- Added request deduplication in data fetching +- Improved state updates efficiency + +##### Code Quality +- Removed duplicate code and redundant interfaces +- Enhanced code readability with proper formatting +- Added proper error handling for async operations +- Improved type conversions for balance handling + +#### Technical Details +- Refactored `EscrowPayload` to use TypeScript's utility types +- Consolidated balance handling logic with proper type conversions +- Improved hook dependencies in `escrow-detail-dialog.hook.ts` +- Enhanced service layer with proper type definitions + +#### Impact +- Reduced potential for runtime errors through enhanced type safety +- Improved maintainability through better code organization +- Enhanced performance through proper memoization and state management +- Better developer experience with clearer type definitions + +#### Breaking Changes +None. All changes are backward compatible. + +#### Migration +No migration needed. Changes are transparent to existing implementations. diff --git a/instructions/folder_structure.md b/instructions/folder_structure.md new file mode 100644 index 0000000..fc0a516 --- /dev/null +++
