Technical & Commercial Insights
Frequently Asked Questions on ZK KYC
Get clear, specific answers to the most common questions from CTOs and founders evaluating StarkNet-based identity verification solutions.
A standard ZK KYC system deployment on StarkNet takes 4-6 weeks from kickoff to mainnet launch. This includes 1 week for requirements & design, 2-3 weeks for Cairo contract development and circuit design, 1 week for integration testing with your frontend, and 1 week for final security review and deployment. Complex, multi-jurisdictional logic can extend this to 8-10 weeks.
