.NET Bitcoin & Altcoins library

Features

  • Compatible with Bitcoin Core RPC API.
  • Strongly-typed structures for complex RPC requests and responses.
  • Implicit JSON casting for all RPC messages.
  • Extended methods for every-day scenarios where the built-in methods fall short.
  • Exposure of all RPC API's functionality as well as the extended methods through a single interface.
  • Custom RPC exceptions.
  • Supports all Bitcoin clones.
  • Can operate on unlimited daemons with a single library reference.
  • Bitcoin, Litecoin, Dogecoin, SmartCash, Dash and other Altcoins included.
  • Each coin instance can be fully parametrized at run-time and implement its own constants.
  • Demo client included.
  • Disconnected raw RPC connector included for quick'n'dirty debugging.
  • Handles and relays RPC internal server errors along with their error code.
  • Can work without a .config file.
  • Fully compatible with Mono.
  • Test Network (testnet) and Regression Test Mode (regtest) ready.
  • Fully configurable.

Donations

This library took a significant amount of time and effort to build and requires continuous maintenance in order to keep up with changes introduced with every new Bitcoin-Core release. Keep it up by donating at: 15Nb3RhMd13zp5Pc7yngUon83nFtEZUyBA

NuGet packages

BitcoinLib is available on NuGet:

Versioning

From version 1.4.0, BitcoinLib follows Semantic Versioning 2.0.0.

Building from source

To build BitcoinLib from source, you will need either the .NET Core SDK or Visual Studio.

Linux-specific

If you are using Linux you will also need Mono installed (in order to run Paket). The full install sequence (for Ubuntu) will be something like this.

Building & running tests

With Visual Studio you can build BitcoinLib and run the tests from inside the IDE, otherwise with the dotnet command-line tool you can execute:

dotnet build src/BitcoinLib.sln

The first time you run it, this will use Paket to restore all the packages, and then build the code.

Instructions for Bitcoin

  • Locate your bitcoin.conf file (in Windows it's under: %AppData%\Roaming\Bitcoin, if it's not there just go ahead and create it) and add these lines: 
    rpcuser = MyRpcUsername
rpcpassword = MyRpcPassword
server=1
txindex=1
  • Edit the app.config file in the Console test client to best fit your needs. Make sure you also update the bitcoin.conf file when you alter the Bitcoin_RpcUsername and Bitcoin_RpcPassword parameters.

Instructions for Litecoin and other Bitcoin clones

  • Perform the same steps as those mentioned above for Bitcoin.
  • Litecoin configuration file is: litecoin.conf under: %AppData%\Roaming\Litecoin and its daemon is: litecoind.
  • Each coin can be initialized by its own interface specification:
    • IBitcoinService BitcoinService = new BitcoinService();
    • ILitecoinService LitecoinService = new LitecoinService();
  • Any bitcoin clone can be adopted without any further installation steps with the use of the generic ICryptocoinService:
    • ICryptocoinService cryptocoinService = new CryptocoinService("daemonUrl", "rpcUsername", "rpcPassword", "walletPassword");
  • Use (ICryptocoinService).Parameters to fully configure each coin pointer at run-time.

Configuration

Sample configuration:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
    <!-- BitcoinLib settings start -->

      <!-- Shared RPC settings start -->
      <add key="RpcRequestTimeoutInSeconds" value="10" />
      <!-- Shared RPC settings end -->

      <!-- Bitcoin settings start -->
      <add key="Bitcoin_DaemonUrl" value="http://localhost:8332" />
      <add key="Bitcoin_DaemonUrl_Testnet" value="http://localhost:18332" />
