Industry Leading Hardware Wallets with Proven Secure Element Technology
Ledger is the most widely used hardware wallet brand globally, trusted by millions of users. Their current Nano S Plus, Flex, and Stax models use the STMicroelectronics ST33K1M5 secure element certified at CC EAL6+, with the older Nano X using the ST33J2M0 at CC EAL5+. All run BOLOS, a custom operating system designed specifically for hardware wallet security. The Ledger Live companion app provides a unified interface for managing crypto assets, staking, and accessing DeFi protocols.

Our Verdict
Ledger remains the go to recommendation for most users due to the combination of strong hardware security, broad compatibility, and the Ledger Live ecosystem. The closed source firmware is a valid concern for security purists, but for the majority of crypto holders, Ledger provides the best balance of security, usability, and coin support available today.
