Ledger Blue

End of life: This product is no longer in active production. The manufacturer remains active with newer models.

The Ledger Blue was a premium hardware wallet produced by Ledger, a French cryptocurrency security company. Launched in 2016, it was positioned at the high end of the Ledger lineup, featuring a large color touchscreen in a form factor closer to a tablet than the slim Nano series. It was designed to appeal to both individual power users and enterprise environments that needed clear transaction confirmation on a larger display.

Custody: non-custodial. Cryptographic secrets never left the secure chip, and all transactions displayed on the device screen before signing, following the What You See Is What You Sign (WYSIWYS) model.

The device used a dual-chip architecture: a general-purpose microcontroller paired with an EAL6+ certified Secure Element that isolated all private key operations. It connected to a computer via USB and ran BOLOS (Blockchain Open Ledger Operating System), which allowed multiple third-party applications to run in isolated partitions on the device.

While active, the Ledger Blue supported Bitcoin, Ethereum, XRP, Litecoin, and dozens of other assets via installable apps through the Ledger Live desktop application. Support for ERC-20 tokens and additional blockchains was available through the app ecosystem.

Discontinued: Ledger discontinued the Blue around 2020 and it is no longer sold or actively supported. Ledger’s current lineup consists of the Nano S Plus, Nano X, Flex, and Stax. Users who still own a Ledger Blue device can continue to use it with Ledger Live, though Ledger no longer provides firmware updates for the product and it should be treated as end-of-life hardware.
