Some of the examples included: Chain interation, Ether transfer, Transaction Signing, 1559 Fees, Interaction with Smart contracts and events, Smart contracts structs, Log and Blockchain Processing, Gnosis Safe, ENS, ERC20 and ERC721 presets, Hd Wallets, L2 Optimism, EIP712 Sign and recover a typed message, Abi Encoding, Key Store, Quorum, and many more...
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.
The simplest way to get started, is to use one of the provided examples or templates
The nethereum templates pack includes templates to work and create smart contract libraries, standalone or using a contract framewowrk like Open Zeppelin. It also includes Blazor wasm and server project templates that integrate with Metamask or Siwe (Sign with Ethereum)

This projects provides the quick start example/template on how to integrate Metamask + Nethereum using Blazor interop. The project allows you to work both in Wasm and Server side, so you can create a fully decentralised application using Wasm or semi-decentralised using server hosted components (Web3+Web2).
Both project types include and example on how to:
- Configure Metamask as a UI host provider
- Connect to Metamask
- Interact with Ethereum using simple Web3 rpc calls (Blockhash and ChainId)
- How to create a generic component for ERC20 token transfer including simple validation using FluentValidation
- How to use the EthereumAuthenticationStateProvider and the claim role "EthereumConnected" with connected account
- How to override the default styles of the Metmask component
Source and more info: https://github.com/Nethereum/Nethereum.Templates.Siwe
The Nethereum SIWE template provides an starting point of signing and authentication using Ethereum accounts and the standard SIWE message. The templates provides the following use cases, and how SIWE can be implemented using the Nethereum libraries.
- Rest Api
- Blazor Wasm + Rest Api
- Blazor Server side (standalone)
- Maui (Future template with Rest Api)
- Avalonia (Future template with Rest Api)

Nethereum Explorer is a .Net Blazor Wasm SPA, Desktop Windows and Mac, Android and iOS light blockchain explorer and simple wallet Template.
You can try it here: https://explorer.nethereum.com
Source and more info: https://github.com/Nethereum/Nethereum.UI.Desktop
Functional sample of a Reactive Cross platform desktop wallet connecting to Ethereum using Nethereum, Avalonia and ReactiveUI.
The aim of the starter kit is to provide a continous improving shell allowing to focus only on the developing the specific screens that provide the integration with smart contracts.
The main example for this is the Standard Token component which provides the desktop views and view models
Nethereum can be installed as a Unity Package using the following git repository: https://github.com/Nethereum/Nethereum.Unity
Source and more info: https://github.com/Nethereum/Unity3dSampleTemplate
- Output to the log the current BlockNumber using Unity.UI both in Async and coroutines
- Ether transfer using Web3 and coroutines
- Smart contract deployment (ERC20), Transactions (Transfer) and Querying (Balance)
- Using 1559 Suggestion strategies or Legacy mode when tranfering Ether
- Cross Platform architecture for both Coroutines and Task to enable the reuse of your code using different deployments Native /Desktop or Browser using Metamask)
- Metamask connectivity in browser
