    1. Solo dev, 3 months in — shipped an on-chain reputation + identity system for AI agents. Would love eyes on the contracts before our Zenith Security audit wraps.
    2. Built a self-custody app that locks your crypto so you can't panic-sell
    3. I built a mobile crypto trading app. It works. Nobody trades in it. Zero users. How do I fix distribution?
