# Nethereum DevChain

A blockchain that runs inside your test project

## What this does

Testing contract code usually means running a separate node process alongside your project. This gives you an Ethereum chain in-process from .NET instead, so tests, forks and debugging happen inside your own code. Reach for it when you are writing integration tests, want to fork a network, need to impersonate an account, or want to step through what a transaction actually did.

### Top 3 things it does for you

- Run a local Ethereum chain for development
- Write integration tests against a real chain
- Fork a live network to try something out

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Nethereum DevChain

Runs a local Ethereum dev chain from .NET with Nethereum DevChain, in-process rather than as a separate tool, and can stand in where Hardhat or Anvil would otherwise be used.

It covers writing integration tests, forking networks, debugging transactions, snapshot and revert, account impersonation, and debug_traceTransaction - anything that needs a local EVM for development and testing in C# or .NET.

## Questions

### Is Nethereum DevChain safe to install?

AIR scanned this exact version of Nethereum DevChain and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 1d68d2b03605, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/devchain.

### How do I install Nethereum DevChain?

Open https://airmarket.ai/app/devchain on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/Nethereum/Nethereum/tree/1d68d2b036054226a11179eb1d1bda57f30a5365/plugins/nethereum-skills/skills/devchain. Install from that link, not the branch.
