Bitcoinlib — cryptean

BitcoinLib is an open-source C#/.NET library that wraps Bitcoin Core-compatible RPC calls for Bitcoin and supported Bitcoin-derived coins. It provides strongly typed request and response structures, JSON casting, convenience methods, and a shared interface for daemon RPC operations.

Practical overview

When it fits

Use BitcoinLib when a .NET application needs a client-side interface to a configured Bitcoin Core-compatible daemon, particularly when typed messages or shared handling across supported coins are useful.

Who it is for

  • .NET developers building applications that communicate with Bitcoin Core-compatible daemons.
  • Developers integrating Bitcoin, Litecoin, Dogecoin, SmartCash or Dash RPC operations.
  • Teams that want typed RPC messages or a common interface for configuring multiple coin daemons.

Documented uses

  • Issue Bitcoin Core-compatible RPC calls from a .NET application.
  • Represent complex RPC requests and responses with typed structures and JSON casting.
  • Use convenience methods alongside the daemon’s RPC functionality.
  • Configure multiple coin daemons through a shared library interface.
  • Direct RPC work toward testnet or regtest configurations.
Before you choose

Requirements & limits

The repository is public and MIT-licensed. The README says the package is available on NuGet and lists the .NET Core SDK or Visual Studio for building from source.

  • A compatible coin daemon and its RPC credentials must be configured separately from the library.
  • The README names Bitcoin, Litecoin, Dogecoin, SmartCash and Dash, and describes support for other Bitcoin clones.
  • The project includes a demo client and a disconnected raw RPC connector for debugging.
  • The README identifies Mono compatibility and testnet/regtest readiness.
  • Source builds require the .NET Core SDK or Visual Studio; the documented command-line build command is dotnet build.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Configure Bitcoin RPC for the demo client

Set up the documented Bitcoin daemon RPC settings and align the demo client credentials.

Before you start

  • A Bitcoin Core daemon and access to its bitcoin.conf file.
  • The BitcoinLib Console test client and its app.config file.

Steps

  1. Add rpcuser, rpcpassword, server=1 and txindex=1 to bitcoin.conf.

  2. Set the Bitcoin daemon URL, RPC username and RPC password in the client configuration.

  3. Keep the credentials in the daemon and client configuration aligned.

Expected outcome

The documented settings connect the demo client configuration to a Bitcoin daemon’s RPC interface.

Guide limitations

  • This recipe covers configuration only; it does not establish a successful connection or RPC operation.
  • The README’s configuration example includes wallet-password and timeout settings, but does not require changing them for this setup.
