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.
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.
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.
The Blue embeds a color display and a large capacitive touchscreen with anti scratch glass, encased in a strong cover.
The Blue is built upon an advanced operating system that supports easy installation of applications, accessible via a quick-launch dashboard.
Your confidential data is never exposed: it is strongly secured and isolated inside a Secure Element, locked by a PIN code.
Ledger Blue uses WYSIWYS (What You See is What You Sign) to mitigate threats.
The configuration of your device is backed up on a recovery sheet. Easy restoration on any Ledger device or compatible wallets.
