+
+### Refactor: Improved Escrow Service Architecture and Type Safety
+
+#### PR Description
+This PR introduces significant architectural improvements to the escrow service layer, enhancing type safety, maintainability, and performance. 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.
