Core Capabilities of Our API Gateway Service
Our Secure API Gateway for Vault Access provides the hardened infrastructure and fine-grained controls required to manage digital assets at scale, without compromising on security or developer experience.
01
Zero-Trust Authentication & Authorization
Enforce strict access policies with multi-party computation (MPC) signatures, role-based access control (RBAC), and hardware security module (HSM) integration. Every API call is cryptographically verified, ensuring only authorized actions are executed.
SOC 2 Type II
