Frequently Asked Questions
Get clear, technical answers to common questions about implementing a privacy-preserving identity layer with ZK-Rollups.
A production-ready ZK-Rollup identity layer typically takes 8-12 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design, 4-5 weeks for core development (circuits, contracts), 2 weeks for security audits, and 2-3 weeks for integration and testing. For a proof-of-concept with basic features, we can deliver in 4-6 weeks.
