Frequently Asked Questions
Get clear answers about our service for building verifiable, privacy-preserving financial data systems.
A standard implementation for a single financial data feed (e.g., portfolio valuation, credit scoring) takes 4-6 weeks from kickoff to production. This includes circuit design, integration with your data source, on-chain verifier deployment, and security review. More complex multi-source aggregations or custom proving schemes can extend to 8-12 weeks.
