# Deploy a Contract

Get a contract on-chain from C# and get its address back

## What this does

You have written a smart contract and now it has to go on Ethereum, from your C# code. This handles the deployment: passing the constructor values, checking what the gas will run to, and handing you back the address afterwards. Reach for it the first time you publish a contract, and every time after.

### Top 3 things it does for you

- Deploy a smart contract from .NET
- Pass constructor arguments at deployment
- Estimate the gas a deployment will cost

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 Deploy a Contract

Deploys smart contracts to Ethereum from .NET and C# using Nethereum's typed deployment handlers.

It covers deploying and publishing a contract, supplying constructor parameters, estimating deployment gas, and retrieving the contract address once the deployment is done.

## Questions

### Is Deploy a Contract safe to install?

AIR scanned this exact version of Deploy a Contract 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/deploy-contract.

### How do I install Deploy a Contract?

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