END-TO-END BIOMETRIC SSI WALLET DEVELOPMENT
Core Technical Capabilities We Deliver
We build enterprise-grade, self-sovereign identity wallets that combine biometric security with blockchain verifiability. Our full-stack development delivers production-ready solutions for KYC/AML, secure access, and verifiable credentials.
01
Biometric Authentication Engine
Secure, on-device biometric binding (Face ID, Touch ID, fingerprint) with liveness detection to prevent spoofing. Private keys are never stored on servers, ensuring true user sovereignty and compliance with privacy regulations like GDPR.
