Frequently Asked Questions
Get clear answers on how we build secure, anonymous voting systems that work across multiple blockchains.
A standard implementation takes 4-8 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design and ZK-circuit specification, 3-4 weeks for core development and internal testing, and 1-2 weeks for audit preparation and deployment. Complex integrations (e.g., 5+ chains, custom privacy models) may extend the timeline, which we scope and agree upon upfront.
