# Smart Contract Interaction

Talk to Ethereum contracts from C# with types that hold

## What this does

You are building in C# and need your code to talk to contracts on Ethereum. This covers the everyday moves: deploying, calling functions, sending transactions, reading events back, checking past state, and estimating cost. Reach for it whenever contract calls are the part of your app you are working on.

### Top 3 things it does for you

- Deploy a contract and call its functions from .NET
- Read events back out of transactions
- Query what the chain looked like earlier

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 Smart Contract Interaction

This is for interacting with Ethereum smart contracts from C# and .NET using Nethereum's typed DTOs. It covers deploying contracts, calling their functions, and sending transactions to them.

It also covers decoding events, querying historical state, estimating gas, and offline signing, plus working with an ABI directly when a type-safe approach is not what you want.

Reach for it whenever contract interaction is the thing you are actually writing.

## Questions

### Is Smart Contract Interaction safe to install?

AIR scanned this exact version of Smart Contract Interaction 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/smart-contract-interaction.

### How do I install Smart Contract Interaction?

Open https://airmarket.ai/app/smart-contract-interaction 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/smart-contract-interaction. Install from that link, not the branch.
