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:

publicasyncTaskDisplayAddress(){WindowsHidDeviceFactory.Register(newDebugLogger(),newDebugTracer());varledgerManagerBroker=newLedgerManagerBroker(3000,null,null,newLedgerManagerFactory());varledgerManager=(IAddressDeriver)awaitledgerManagerBroker.WaitForFirstDeviceAsync();varpath=$"m/49'/0'/0'/0/0";varaddressPath=AddressPathBase.Parse<BIP44AddressPath>(path);varaddress=awaitledgerManager.GetAddressAsync(addressPath,false,true);}
