A Go client library for interacting with the Sia app on Ledger hardware wallets.

Features

• Open and communicate with Ledger devices over USB (HID) or TCP (for emulator testing)
• Retrieve the app version
• Get public keys and addresses at a given BIP-44 index
• Sign hashes with a device-held private key
• Calculate and display v1/v2 transaction hashes on the device
• Sign v1/v2 transactions on the device

Installation

go get go.sia.tech/ledger-go

Usage

device, err := ledger.Open()
if err != nil {
    log.Fatal(err)
}
defer device.Close()

version, err := device.GetVersion()
if err != nil {
    log.Fatal(err)
}
fmt.Println("Sia app version:", version)

addr, err := device.GetAddress(0)
if err != nil {
    log.Fatal(err)
}
fmt.Println("Address:", addr)
