Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for building scalable city infrastructure on Substrate.
Standard deployments take 4-8 weeks from kickoff to mainnet launch. A typical breakdown: 1-2 weeks for architecture & design, 2-4 weeks for core pallet development and testing, and 1-2 weeks for deployment and integration. Complex systems with custom consensus or advanced privacy features may extend this timeline. We provide a detailed project plan with milestones during the initial consultation.
