At Ledger, security is our core architecture. Our hardware wallets integrate a dedicated Secure Element chip, a tamper-evident silicon component that isolates your cryptographic keys from the rest of the system. This chip runs on the BOLOS operating system, a hardened, open-source kernel designed specifically for cryptographic resilience. By leveraging hardware-level protection, we ensure that even if the device is physically compromised, your private keys remain inaccessible to malicious actors. This modular approach to security provides a robust foundation for managing digital assets with absolute confidence.
