Hardware Wallets

Hardware wallets are portable devices that safely store private keys. Tamper proof chips erase internal memory if microscopic seals are broken, which keeps keys from ever being seen by human eyes. Communication with the DApp happens via the Chip Card Interface Device (CCID) USB protocol.

LX allows users to choose between storing their private keys in their own hardware or inside the Yubikey NEO, a hardware authentication device manufactured by Yubico that supports one-time passwords, public-key encryption and authentication, and the FIDO Alliance’s Universal 2nd Factor (U2F) protocol.

Yubico’s GitHub repository provides low level C libraries for hardware integration, a U2F Server C Library, amongst other resources for the LX DApp development.
