Getting Started with BTCWalletLibrary

Prerequisites

• .NET Standard 2.0+ SDK
• Basic knowledge of Dependency Injection in .NET

---

Step 1: Install NuGet Package

Install the BTCWalletLibrary NuGet package in your .NET project:

dotnet add package BtcWalletLibrary

---

Step 2: Configure Settings

Create an appsettings.json file in your project root, example file:

{
  "CryptoWalletLibrary": {
    "NodeConfiguration": {
      "Url": "testnet.aranguren.org",
      "Port": 51001,
      "UseSSL": false,
      "Network": "TestNet",
      "MaxRangeEmptyAddr": 2
    },
    "BlockchainTxFeeApi": {
      "BaseUrl": "https://api.blockchain.info",
      "FeePath": "/mempool/fees"
    }
  }
}

Note: Set the file's Copy to Output Directory property to Copy Always.

---

Step 3: Initialize the Library

Configure the library using Microsoft.Extensions.DependencyInjection:

// Build configuration
var configuration = new ConfigurationBuilder()
    .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
    .Build();

// Configure wallet library config
services.Configure<WalletConfig>(configuration.GetSection("CryptoWalletLibrary"));

// Setup dependency injection
var services = new ServiceCollection();

// Configure logging (Serilog shown here as example)
Log.Logger = new LoggerConfiguration()
    .MinimumLevel.Verbose()
    .WriteTo.Console()
    .CreateLogger();
services.AddSingleton<ILoggingService, SerilogLoggingService>();


// Initialize with test mnemonic for demo purposes (replace with secure key management in production)
const string testMnemonic = 
    "asthma attend bus original science leaf deputy nuclear ticket valley vacuum tornado";
services.AddBtcWalletLibraryServices(testMnemonic);

// Build service provider
var serviceProvider = services.BuildServiceProvider();

Implementation Notes

• The example uses:
  • Microsoft.Extensions.DependencyInjection for DI
  • Serilog for logging (optional)
  • .NET's built-in configuration system
• Works in any .NET Standard 2.0+ compatible project:
  • Console apps
  • ASP.NET Core services
  • Desktop applications
  • Mobile apps (via .NET MAUI/Xamarin)
