Would you like to contribute?

Quick Start

• Clone the repo and open the solution
• Connect Ledger and enter pin
• Open Bitcoin app on the device
• Run the GetBitcoinPublicKey unit test
• Repeat for Ethereum and Tron etc.

For any instructions that are not implemented you will need to create a RequestBase, and ResponseBase class. Then, you will need to call SendRequestAsync or CallAndPrompt.

NuGet: Install-Package Ledger.Net

Example:

public async Task DisplayAddress()
{
    WindowsHidDeviceFactory.Register(new DebugLogger(), new DebugTracer());
    var ledgerManagerBroker = new LedgerManagerBroker(3000, null, null, new LedgerManagerFactory() );
    var ledgerManager = (IAddressDeriver) await ledgerManagerBroker.WaitForFirstDeviceAsync();
    var path = $"m/49'/0'/0'/0/0";
    var addressPath = AddressPathBase.Parse<BIP44AddressPath>(path);
    var address = await ledgerManager.GetAddressAsync(addressPath, false, true);
}
