Frequently Asked Questions
Get clear answers on implementation, security, and integration for your confidential transaction layer.
Standard deployment for a custom Privacy-Preserving Transaction Core takes 3-6 weeks from kickoff to mainnet launch. This includes architecture design, smart contract development, integration with your existing dApp, and security audits. For integrations with existing protocols or simpler use cases, timelines can be as short as 2 weeks. We provide a detailed project plan within the first 3 days of engagement.
