Crate lsdk 

lsdk

A Rust SDK to talk to hardware wallets that run the BOLOS operating system (Nano S, Nano S Plus, Nano X, Stax, Flex, Nano Gen5) over USB HID, from native code or from the browser through WebHID.

The crate is split in layers, each behind a cargo feature so you only pay for what you use:

Layer	Feature	Content
core	(always)	APDU encoding, status words, HID framing, device models, Transport trait, dashboard commands (Device)
native HID	hid	transport::hid::HidTransport built on hidapi
WebHID	webhid	[transport::webhid::WebHidTransport] for wasm32
manager API	manager-api	manager::api::ManagerApi: app catalog, firmware metadata
HSM channel	hsm	hsm: the websocket secure channel used for genuine check, install, update
manager	manager	manager::ops: genuine check, install / uninstall apps, firmware update
apps	eth, btc, sol	app clients (apps) to derive addresses, build and sign transactions

use lsdk::{Device, transport::hid::HidTransport};

let transport = HidTransport::open_first()?;
let device = Device::new(transport);
let version = device.get_version().await?;
println!("{} running {}", version.model().map(|m| m.name()).unwrap_or("?"), version.se_version);

Modules

apdu

APDU command and response types.

appsbtc or eth or sol

App clients: talk to the coin apps running on the device.

attestationattestation

Offline genuine check: device attestation without contacting the vendor.

device

High level device handle with the dashboard commands.

error

Error type used across the crate.

framing

HID framing used by the devices over USB.

hsmhsm

Secure channel with the HSM (“scriptrunner”) over a websocket.

loaderloader

App images and sideloading over the secure channel.

managerhsm or manager-api

Device management: manager HTTP API and high level operations.

model

Device models.

os

Dashboard (BOLOS) commands: version, apps, device name, battery…

path

BIP-32 derivation paths.

scpscp

Dashboard secure channel (SCP) and the secure commands it carries.

transport

Transports carry raw APDUs to a device and bring back raw responses.

Constants

VENDOR_ID

USB vendor id used by all devices.
