> But if I can build my app using smart contracts, then they are always available to execute when needed - just pay to write/execute. I don't need to cover hosting costs or much infrastructure beyond some web interface (which I could just put on Netlify). So you're already using Netlify, why not take the extra step and make your entire app open source and serverless? That solves the "If my startup fails" case, and the hosting costs issue which you'd be incurring either way.
