ENTERPRISE-GRADE SECURITY
Core Technical Capabilities
Our mobile wallet key management solutions are built on a foundation of battle-tested cryptography and secure enclave technology, designed to protect user assets while enabling seamless onboarding.
01
Secure Enclave & TEE Integration
Leverage hardware-backed security with Apple Secure Enclave and Android StrongBox. Private keys are generated, stored, and used exclusively within the Trusted Execution Environment, never exposed to the OS or app memory.
FIPS 140-2

Zero Exposure
Key Policy
02
Multi-Party Computation (MPC)
Implement threshold signatures to eliminate single points of failure. Distribute key shards across user devices and our secure cloud nodes, requiring multiple parties to authorize transactions for enhanced security.

03
Social Recovery & Inheritance
Prevent permanent loss with non-custodial recovery flows. Users designate guardians (friends, hardware wallets) who can collectively help restore access without ever possessing the full key.

Key Management FAQs for Technical Leaders
Answers to the most common technical and operational questions from CTOs and engineering leads evaluating mobile wallet key management solutions.
We implement a multi-layered security architecture combining on-chain and off-chain components. Core private keys are generated and stored in secure enclaves (SE) or Trusted Execution Environments (TEE) on the user's device, never leaving the hardware. We use MPC (Multi-Party Computation) protocols for distributed key generation and signing, eliminating single points of failure. All communication is encrypted via TLS 1.3, and we provide SDKs for iOS (Secure Enclave) and Android (StrongBox/KeyStore).
