Ledger Documentation Hub
This documentation is intended for developers only and not general users.
Ledger produces personal security devices such as the Ledger Nano S and the Ledger Blue, both of which are architected around a Secure Element and the BOLOS platform.
This documentation contains information about developing apps for these devices, from high-level concepts like hierarchical deterministic key generation to low-level details about the hardware architecture of these devices.
