Frequently Asked Questions
Get clear answers about our development process, security, and support for building HIPAA-compliant, self-sovereign identity systems.
We architect systems with privacy-by-design using zero-knowledge proofs (ZKPs) and selective disclosure. Patient data is encrypted off-chain with keys managed via MPC wallets, while on-chain verifiable credentials (W3C VC standard) contain only anonymized attestations. Our development process includes a dedicated security review against HIPAA's Privacy and Security Rules, and we provide an audit-ready architecture document.
