Cross Platform C# Library for the Trezor Cryptocurrency Hardwarewallet

This library allows you to communicate with both Trezor hardwarewallets in the same way that the Trezor browser wallet app communicates with them. It can be used to build apps that send or receive crypto currencies like Bitcoin in a secure way.

Currently supports: .NET Framework, .NET Core, Android, UWP , See MacOS and Linux Support

Would you like to contribute?

• Clone the repo and open the solution
• There is a console sample, Xamarin Forms sample and unit tests for UWP, and .NET
• Compile one of the unit test apps, run the UWP/Android Xamarin Forms apps or,
• Go to Test->Windows->Text Explorer in Visual Studio
• Run one of the unit tests in the pane.
• Note that the UWP unit test has a UI for entering the pin. Please read instructions there.

All Trezor messages are in the Trezor.Net.Contracts namespace. To implement them, you need to call SendMessageAsync

NuGet: Install-Package Trezor.Net

Example:

public async Task<string> GetAddressAsync()
{
    //Register the factory for creating Usb devices. Trezor One Firmware 1.7.x, 1.8.x / Trezor Model T 2.1.x
    WindowsUsbDeviceFactory.Register();
    //Register the factory for creating Hid devices. Trezor One Firmware 1.6.x
    WindowsHidDeviceFactory.Register();

    var trezorManagerBroker = new TrezorManagerBroker(GetPin, 2000, new DefaultCoinUtility());

    var trezorManager =  await trezorManagerBroker.WaitForFirstTrezorAsync();

    var bip44AddressPath = AddressPathBase.Parse<BIP44AddressPath>("m/49'/0'/0'/0/0");

    return await trezorManager.GetAddressAsync(bip44AddressPath, false, true);
}
