Technical & Commercial Insights
StarkNet Development FAQs
Get clear answers to the most common questions CTOs and founders ask when evaluating a StarkNet development partner. Based on our experience delivering 30+ Cairo-based applications.
A standard ZK-rollup application with core smart contracts and a frontend typically deploys in 4-6 weeks. Complex DeFi protocols or gaming ecosystems with custom provable logic can take 8-12 weeks. We follow a phased approach: 1-2 weeks for architecture & design, 2-4 weeks for Cairo development & unit testing, 1-2 weeks for security review & audit preparation.
