# Security Mesh Security is foundational in DeFi trading automation. Selen AI employs a robust set of infrastructure protections: * **Hardware Security Module (HSM)-Backed Key Vault**: Ensures private keys and signing credentials remain in a secure enclave, isolated from external threats. * **Role-Based Access Control (RBAC)**: Granular permissions system to prevent unauthorized access across APIs, features, and user actions. * **Encrypted Environment Secrets**: All environment variables and sensitive config data are encrypted at rest and in transit. This multi-tiered security approach ensures user assets and operational integrity are protected across all surfaces. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
