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


public async Task DisplayAddress()
    var ledgerManagerBroker = new LedgerManagerBroker(3000, null, Prompt);
    _LedgerManager = await ledgerManagerBroker.WaitForFirstDeviceAsync();
    var address = await _LedgerManager.GetAddressAsync(0, false, 0, true);



The community needs your help! Unit tests, integration tests, more app integrations and bug fixes please! Check out the Issues section.


All my libraries are open source and free. Your donations will contribute to making sure that these libraries keep up with the latest firmware, functions are implemented, and the quality is maintained.
