Nethereum is the .Net integration library for Ethereum, simplifying the access and smart contract interaction with Ethereum nodes both public or permissioned like Geth, Parity or Quorum.
Nethereum is developed targeting netstandard 1.1, netstandard 2.0, netcore 2.1, netcore 3.1, net451 and also as a portable library, hence it is compatible with all the operating systems (Windows, Linux, MacOS, Android and OSX) and has been tested on cloud, mobile, desktop, Xbox, hololens and windows IoT.
Go to http://playground.nethereum.com to browse and execute all the different samples on how to use Nethereum directly in your browser. The same version is hosted in IPFS at http://playground.nethereum.eth.link/ or the same https://gateway.pinata.cloud/ipfs/QmPgWmX3HsxCBCDVv8adEhLzeJd2VstcyGh1T9ipKrvU4Y/
Please join the Discord server using this link: https://discord.gg/u3Ej2BReNn We should be able to answer there any simple queries, general comments or requests, everyone is welcome. If you want to help or have any ideas for a pull request just come and chat.
The documentation and guides can be found at Read the docs.
- JSON RPC / IPC Ethereum core methods.
- Geth management API (admin, personal, debugging, miner).
- Parity management API.
- Quorum integration.
- Simplified smart contract interaction for deployment, function calling, transaction and event filtering and decoding of topics.
- Unity 3d Unity integration.
- ABI to .Net type encoding and decoding, including attribute based for complex object deserialization.
- Hd Wallet
- Transaction, RLP and message signing, verification and recovery of accounts.
- Libraries for standard contracts Token, ENS and Uport
- Integrated TestRPC testing to simplify TDD and BDD (Specflow) development.
- Key storage using Web3 storage standard, compatible with Geth and Parity.
- Simplified account life cycle for both managed by third party client (personal) or stand alone (signed transactions).
- Low level Interception of RPC calls.
- Code generation of smart contracts services.
Nethereum provides two types of packages. Standalone packages targeting Netstandard 1.1, net451 and where possible net351 to support Unity3d. There is also a Nethereum.Portable library which combines all the packages into a single portable library. As netstandard evolves and is more widely supported, the portable library might be eventually deprecated.
To install the latest version:
To install the main packages you can either:
PM > Install-Package Nethereum.Web3
or
PM > Install-Package Nethereum.Portable
dotnet add package Nethereum.Web3
or
dotnet add package Nethereum.Portable
If you are working with smart contracts, you can quickly code generate contract definitions using the vscode solidity extension (please check the documentation for other options)

There are a few video guides, which might be helpful to get started. NOTE: These videos are for version 1.0, so some areas have changed.
Please use the Nethereum playground for the latest samples.
These are two videos that can take you through all the initial steps from creating a contract to deployment, one in the classic windows, visual studio environment and another in a cross platform mac and visual studio code.
This video takes you through the steps of creating a smart contract, compiling it, starting a private chain and deploying it using Nethereum.
This hands on demo provides an introduction to calls, transactions, events filters and topics
This video provides an introduction on how to store and retrieve data from structs, mappings and arrays decoding multiple output parameters to Data Transfer Objects
