Enterprise-Grade Security Architecture

When handling user assets, security must be the top priority. Privy has invested considerable resources in building a multi-layered defense system to protect its platform, implementing security best practices at every level of the stack.

Hardware-Isolated Self-Custody: Privy employs a unique key management approach where keys are sharded, encrypted end-to-end, and distributed across isolated services. The technical implementation uses threshold cryptography, meaning that a minimum number of key shares must be combined to perform operations, but no single share reveals any information about the complete key. Wallets are only reconstructed within secure hardware environments using TEE technology, ensuring that only legitimate owners can access their assets. This design not only guarantees security but also preserves users' complete control over their funds, maintaining the self-custody principle that is fundamental to Web3.

Defense-in-Depth Strategy: Privy implements a defense-in-depth strategy to avoid single points of failure. Encrypted networks protect data transmission, ensuring that even if network traffic is intercepted, the data remains secure. Role-based access control (RBAC) and microsegmentation enforce the principle of least privilege, limiting the potential damage from compromised credentials. Each security layer is carefully designed so that even if one layer is breached, others remain intact to provide protection. This approach recognizes that no single security measure is perfect, and multiple overlapping controls provide the most robust protection.
