Frequently Asked Questions
Get clear answers on the technical implementation, security, and business impact of our privacy-first virtual fitting room solution.
Our ZK-Rollup architecture delivers three core benefits for virtual fitting rooms: privacy, scalability, and cost-efficiency. User body scan data and try-on sessions are processed off-chain, with only cryptographic proofs (ZK-SNARKs/STARKs) submitted to the mainnet. This keeps sensitive biometric data private while enabling sub-second visual updates and reducing transaction costs by over 95% compared to on-chain processing. It allows for a seamless, real-time user experience at scale.
