Implement Feature with Tests

Implement the following feature with comprehensive tests: $ARGUMENTS

Implementation Framework:

1. Requirements Analysis: Break down the feature requirements and acceptance criteria
2. Test Planning: Design test cases before implementation
3. Interface Design: Define clean interfaces between components
4. Implementation: Write the code following language best practices
5. Testing: Create comprehensive unit, integration, and property-based tests
6. Documentation: Update relevant documentation and examples

Implementation Standards:

• Code Quality: Follow language conventions and project coding standards
• Error Handling: Implement robust error handling with context
• Logging: Add appropriate logging with structured fields
• Testing: Achieve >90% test coverage for Go, >95% for Solidity
• Performance: Consider performance implications and add metrics
• Security: Validate all inputs and handle edge cases

File Organization:

• Go Code: Place in appropriate pkg/ or internal/ subdirectory
• Solidity Contracts: Place in contracts/ directory
• Frontend Code: Follow Vue 3 project structure
• Tests: Co-locate with source files (*_test.go, .test.js, etc.)
• Documentation: Update docs/ and inline comments

Integration Points:

• Backend: Integrate with existing Go components
• Smart Contracts: Ensure proper contract interaction
• Frontend: Connect to backend APIs and web3 providers
• Monitoring: Add metrics and health checks

Deliverables:

• Working implementation with tests
• Updated documentation
• Configuration updates
• Performance benchmarks if applicable
• Migration guide for existing deployments
