Frequently Asked Questions on ZK KYC Development
Get clear answers on timelines, costs, security, and implementation for your Zero-Knowledge KYC protocol.
A standard ZK KYC protocol deployment takes 4-8 weeks from kickoff to mainnet launch. This includes 1-2 weeks for requirements and architecture, 2-4 weeks for core circuit and smart contract development, and 1-2 weeks for security audits and integration. Complex integrations with existing enterprise systems or custom compliance logic can extend this timeline. We provide a detailed project plan with weekly milestones.
