NBitcoin is the most complete Bitcoin library for the .NET framework, implementing all relevant Bitcoin Improvement Proposals (BIPs) and providing low-level access to Bitcoin primitives. It supports Windows, Mac, and Linux via .NET, .NET Core, Xamarin, and Unity, with an optional NBitcoin.Altcoins package for altcoin support.

Use cases

  • build a bitcoin wallet in C#
  • create and sign bitcoin transactions from .NET
  • generate BIP39 mnemonics and derive HD wallets (BIP32)
  • parse and validate raw bitcoin transactions
  • build a bitcoin payment processor in ASP.NET
  • interact with bitcoin testnet and regtest for development
  • implement multisig and segwit addresses in .NET

When to choose

  • you are building any Bitcoin-related application on .NET, .NET Core, Xamarin, or Unity
  • you need comprehensive BIP coverage and low-level Bitcoin primitives in C#
  • you want a mature, MIT-licensed library with good documentation and unit tests

When to avoid

  • your project is not on the .NET platform
  • you need a full Bitcoin node implementation rather than a library
  • you need support for non-Bitcoin chains not covered by NBitcoin.Altcoins
