Meet NEO: Your FHE Development Partner

Writing smart contracts that compute on encrypted data without ever decrypting it? That's the promise of Fully Homomorphic Encryption (FHE), and it's exactly as tricky as it sounds.

FHE development requires unlearning core assumptions about Solidity – you can't use traditional if statements with encrypted booleans without breaking privacy, every encrypted value needs FHE.allow() for access control, and conditional logic requires FHE.select() instead of if/else branching. Most developers spend weeks figuring out these patterns.

Enter NEO – an AI assistant specifically trained on FHE development patterns for the Fhenix protocol. Load one 30KB file into Claude, ChatGPT, or Gemini, and your AI suddenly understands how to build encrypted smart contracts properly.

What NEO Knows

NEO has mastered the complete FHE development stack:

• All encrypted types: ebool, euint8-256, eaddress and their operations
• Access control patterns: The critical FHE.allow* functions that prevent security vulnerabilities
• Conditional logic: How to use FHE.select() when you can't use if/else
• Decryption workflows: Multi-transaction patterns for revealing encrypted data
• Common pitfalls: What breaks FHE contracts and how to avoid it

The key insight NEO drills into every developer: "Without FHE.allow() = passing a locked box without the key!"
