OpenAI's Codex tried hacking DeFi protocols from zero knowledge:

10% success rate cold

70% success with context/documentation

The gap? AI can spot vulnerabilities but can't weaponize them into exploits yet.

Feels safe today ≠ safe tomorrow

AI agents are learning fast. What takes 10 attempts now might take 1 in 6 months.

If you're building in DeFi and banking on "AI can't hack us"—you're already behind.
