AI Training Materials for Fully Homomorphic Encryption (FHE) Smart Contract Development using Fhenix
NEO is a comprehensive training resource that helps you transform AI assistants (Claude, ChatGPT, Gemini, etc.) into expert FHE developers. By loading NEO’s reference materials into your AI assistant, you’ll get expert-level guidance on building confidential smart contracts with Fhenix.

​
Getting Started

  1. Clone or Access the Repository Visit the FHE Assistant repository on GitHub
  2. Load Core.md into Your AI Copy the contents of core.md into your AI assistant’s context window
  3. Start Building Use the proven prompts above to generate FHE-compatible smart contracts

​
Loading into AI Platforms

Claude Code: 
claude "Read the fhe-assistant/core.md file and help me build FHE smart contracts using these patterns"
Other AI Platforms (ChatGPT, Gemini, etc.): Copy-paste the core.md file and say: “This is FHE reference material. Help me build encrypted smart contracts.”

​
Proven AI Prompts

Once you’ve loaded NEO’s reference materials, try these proven prompts:

​
Code Generation

  • “Build me a [voting/auction/gaming] contract using FHE patterns”
  • “Create an encrypted token with private balances”

​
Code Review

  • “Review this FHE contract against the security checklist”
  • “Fix this contract that has FHE access control errors”

​
Learning

  • “Explain FHE access control and show me working examples”
  • “Why can’t I use ebool in if statements? Show me the right way”

​
What’s Inside

The NEO repository includes: 📚 core.md → Comprehensive FHE library reference (EVERYTHING YOU NEED) 📖 README.md → Quick start guide

​
Core.md Contents

The comprehensive reference file includes:
  • 🔢 All encrypted data types - ebool, euint8-128, eaddress
  • ➕ Complete operation reference - Arithmetic, comparison, logical operations
  • 🔐 Access control patterns - FHE.allow*, critical for security
  • 🔄 Conditional operations - FHE.select - the only way to use ebool
  • 🔓 Decryption workflows - Multi-transaction patterns
  • 🚨 Common mistakes - Debugging guide and pitfalls to avoid
  • ✅ Working code templates - Ready-to-use examples

​
Why Use NEO?

Building with FHE requires understanding specific patterns and security considerations that differ from standard Solidity development. NEO provides:
  • Complete Reference - All FHE types and operations in one place
  • Security Patterns - Access control and encryption best practices
  • Working Examples - Real code templates you can use immediately
  • Common Pitfalls - Learn from mistakes others have made
  • Fhenix-Specific - All patterns target Fhenix protocol directly
