ENTERPRISE-GRADE SECURITY & PERFORMANCE
Core Technical Capabilities
Our Mobile MPC & TSS Wallet Service is engineered for production. We deliver battle-tested infrastructure that scales with your user base while maintaining the highest security standards.
01
Threshold Signature Scheme (TSS) Architecture
Multi-party computation (MPC) eliminates single points of failure. Private keys are never stored in full, providing native protection against exchange hacks and insider threats. Supports ECDSA and EdDSA curves.
