  • AI-powered secure matching system
  • Privacy preservation with encrypted data
  • Smart contract payment integration
  • Performance analytics & visualizations
  • Educational resources for novices

Key Decisions

01

Selected the Oasis Sapphire network specifically to utilize its "Confidential State," ensuring that the copy-trading logic and professional wallet balances remain encrypted and inaccessible to external MEV bots.

02

Engineered a "Privacy-First Matching" prompt for Gemini AI that ranks traders based on risk-profile mathematical vectors rather than exposing raw PII to the LLM context.

Learnings

→Mastered the nuances of Confidential EVM (cEVM) where traditional "view" functions must be strictly gated to prevent accidental leakage of private contract state.
→Developed a deep understanding of bridging encrypted on-chain data with off-chain AI inference without compromising the end-to-end encryption tunnel.
