Ledger Blue is the most advanced hardware security gear on the market. It boasts multi-application execution, and packs enterprise-level crypto-capabilities into a lightweight handheld device designed and crafted in France. It is designed around a Secure Element, featuring a touchscreen and USB and Bluetooth connectivity.
A Powerful and Flexible Device
The Ledger Blue is the latest generation product from Ledger, result of more than two years of research and development. This high-end device embeds a large touchscreen to securely manage transactions and complex smart contracts. Its slick yet robust casing encloses the best-in-class technology built upon the Blockchain Open Ledger (BOLOS) platform, a powerful and flexible operating system.
Packed with Hardware Features
The Ledger Blue is based on a dual-chip architecture embedding a ST31 Secure Element and a STM32 microcontroller thus achieving a fully isolated environment. It features a LED-backlit color touchscreen to navigate easily and validate transactions. It is powered by a LiPo rechargeable battery and communicates with USB or Bluetooth devices.
Designed for Multiple Secure Apps
Thanks to its modular architecture, the Ledger Blue runs multiple dedicated companion apps in full isolation on top of its firmware. The strong security model allows to add new cryptocurrencies or apps without risk of compromising the master seed. Transaction integrity is ensured by the WYSIWYS paradigm (What You See Is What You Sign). The flexibility of the device enables enterprise level usage: with all major crypto libraries embedded in the firmware, any type of blockchain can be supported.
Battery-powered, Bluetooth and USB enabled, the Ledger Blue can operate with any computer and smartphone.
- Battery 500mA LiPo
- BLE 4.1, USB 2.0 Full Speed, NFC (requires firmware update)
- Windows, Mac OS, Linux and Chrome OS
The Blue embeds a color display and a large capacitive touchscreen with anti scratch glass, encased in a strong cover.

- BOLOS isolation technology
- 4 to 8 digit PIN code
Ledger Blue uses WYSIWYS (What You See is What You Sign) to mitigate threats.
- Malwares, viruses
- Man in the middle attacks
- Proof of presence
Backup and Restoration
The configuration of your device is backed up on a recovery sheet. Easy restoration on any Ledger device or compatible wallets.
- Built-in onboarding and configuration
- BIP39 and BIP44 standards
- 12, 18 or 24 words recovery
Ledger Blue is based on a dual chip architecture (ST31/STM32, Certification level: CC EAL6+). The firmware integrity is guaranteed by cryptographic attestation.
Ledger Blue ensures only you can access your apps by requiring a 4 to 8 digit PIN code each time you unlock your device.
Initialization or restoration of your master seed is fully done on the secure environment of the Ledger Blue. Your cryptographic secrets are never exposed to the outside world.
Your private keys are never held or known by Ledger or a third party: they are hard locked in the Secure Element. Applications run in full isolation, data from one app cannot be accessed by another.
