# EVM Simulation - Nethereum.EVM

See what a transaction would do before you send it

## What this does

Sending a transaction and finding out afterwards that it failed, or did something unexpected, is expensive. This runs it locally first from .NET so you can see the state changes, the token movements, the call tree, and the actual revert reason. Reach for it when a transaction is failing for reasons you cannot see, or before you commit to one.

### Top 3 things it does for you

- Preview the state changes a transaction would cause
- Find out why a transaction reverted
- Trace the calls a transaction makes

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 EVM Simulation - Nethereum.EVM

Simulates Ethereum transactions locally with Nethereum.EVM in .NET: previewing state changes, decoding call trees, extracting token transfers, and decoding revert reasons.

It also covers EVM debugging more broadly - bytecode execution and disassembly, opcode analysis, custom error decoding, ERC-20 simulation and balance change extraction - whenever local EVM execution from C# or .NET is what is needed.

## Questions

### Is EVM Simulation - Nethereum.EVM safe to install?

AIR scanned this exact version of EVM Simulation - Nethereum.EVM 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/evm-simulation.

### How do I install EVM Simulation - Nethereum.EVM?

Open https://airmarket.ai/app/evm-simulation 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/evm-simulation. Install from that link, not the branch.
