Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building secure, decentralized identity solutions.
We deliver a production-ready MVP in 4-6 weeks for a standard implementation (e.g., facial recognition with on-chain verification). Complex systems with custom liveness detection or multi-modal biometrics (face + voice) typically take 8-12 weeks. This includes smart contract development, SDK integration, and a full security audit.
