N/A - Smart contract implementation

💥 Breaking Changes

• This PR introduces breaking changes

• What breaks:
• Migration path:

📊 Performance Impact

• CPU/Memory: Optimized algorithms with O(1) lookups for core operations
• Gas costs: Efficient storage patterns with minimal read/write operations
• Network: Compact data structures and batch operations where possible

🔒 Security Considerations

• Risks:
  • Access control via address authorization
  • Oracle verification for high-value claims
  • Quorum requirements for governance changes
  • Reserve ratio enforcement for pool stability
• Mitigations:
  • Multi-layer validation (AI + Oracle)
  • Configurable risk limits and caps
  • Time-locked governance execution
  • Comprehensive error handling

📖 Additional Context

This implementation provides a production-ready insurance system that can be immediately integrated with the TeachLink platform. The modular design allows for future enhancements such as:

• Machine learning integration for risk prediction
• DeFi composability with yield farming
• Advanced cross-protocol integrations
• Layer 2 scaling solutions

🚀 Deployment Notes

• Requires contract redeployment (new contract)
• Requires data migration
• Requires configuration changes
• No deployment changes needed for existing contracts
