PROVEN PROCESS
Our Delivery Methodology
A structured, security-first approach to integrating hardware-secured private keys into your mobile application, ensuring a seamless user experience without compromising on enterprise-grade security.
01
Architecture & Threat Modeling
We begin with a comprehensive security assessment of your mobile stack. Our team designs a threat model specific to your application, identifying attack vectors and defining the security boundaries for key storage and transaction signing.
OWASP MASVS
Compliance
Zero-Trust
Model
02
Hardware SDK Integration
Seamless integration of vendor-specific SDKs (e.g., YubiKey, Ledger, Apple Secure Enclave, Android Keystore). We handle the complex native bindings, secure channel establishment, and key attestation to prove key residency.

Mobile Hardware Security
Frequently Asked Questions
Common questions about integrating secure, hardware-backed private key storage into your mobile applications.
A standard integration for a single platform (iOS or Android) takes 2-3 weeks from kickoff to production-ready deployment. This includes architecture review, SDK integration, secure enclave/Keystore implementation, and a full security audit of the integration layer. Multi-platform or complex multi-signature setups typically extend the timeline to 4-5 weeks.
