Frequently Asked Questions
Get clear answers on our development process, security, and support for your mobile zero-knowledge proof verifier.
A mobile zero-knowledge proof verifier is a lightweight SDK or library that allows mobile apps to verify cryptographic proofs locally on a user's device, without querying a blockchain node. You need one to enable privacy-preserving features like private logins, selective credential disclosure, or off-chain transaction validation. This reduces server load, enhances user privacy, and improves app performance by moving verification logic to the edge.
