# Transaction Models

Build, read and pick apart Ethereum transactions in .NET

## What this does

Ethereum has several transaction shapes and it is easy to lose track of which one you are holding. This helps you create, decode and inspect them from .NET, and handle the pieces around them like chain IDs and block headers. Reach for it when a transaction is not doing what you expected and you need to look inside.

### Top 3 things it does for you

- Create a transaction of the type you need
- Decode a raw transaction to see inside it
- Recover who signed a transaction

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 Transaction Models

This covers Ethereum transaction types and models in Nethereum: creating, decoding, and inspecting transactions, including legacy, EIP-1559, EIP-2930, and EIP-7702.

It also covers chain IDs, block headers, access lists, transaction recovery, and TransactionFactory.

Reach for it when transactions themselves are what you are working with, rather than the contracts behind them.

## Questions

### Is Transaction Models safe to install?

AIR scanned this exact version of Transaction Models 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/transaction-models.

### How do I install Transaction Models?

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