Ledger Nano S for developers

The Ledger Nano S is a personal lightweight mobile device architectured around a ST31 secure element with USB connectivity.

It is based on BOLOS (Blockchain Open Ledger Operating System), where apps can run securely in full isolation and leverage the main secrets (BIP39 seed) through allocated derivations.

The Nano S can be purchased from Ledger shop and resellers.
