ZK Credit Scoring
Frequently Asked Questions
Common questions about our end-to-end development of private, on-chain credit scoring systems.
From initial design to mainnet deployment, a standard ZK-based credit scoring contract system takes 4-8 weeks. This includes 1-2 weeks for requirements & circuit design, 2-3 weeks for core development and testing, and 1-2 weeks for audit preparation and final deployment. Complex integrations with existing data oracles or multi-chain deployments can extend this timeline.
