Frequently Asked Questions
Get clear answers on timelines, security, and process for integrating zero-knowledge privacy with your multi-chain infrastructure.
A standard integration project takes 4-8 weeks from kickoff to mainnet deployment. This includes architecture design, smart contract development, ZK circuit implementation, and rigorous testing. Complex protocols with custom privacy logic or support for 5+ chains may extend to 12 weeks. We provide a detailed project plan within the first week.
