# ABI Encoding with Nethereum

Turn contract calls and results into data your .NET code can read

## What this does

Ethereum contracts talk in a packed data format that is unreadable by eye. This helps you build that data for a call you want to make, and unpack it when a contract answers back. Reach for it when you are wiring contract calls or reading event and error data in .NET.

### Top 3 things it does for you

- Encode a function call before sending it
- Decode what a contract returned
- Work out a function selector

## About ABI Encoding with Nethereum

Ethereum contracts expect their inputs and return their outputs in the ABI format. This covers encoding function calls and decoding contract output with Nethereum, so the boundary between your code and the chain is something you can work with directly.

It also covers the surrounding pieces: event topics, parsing ABI JSON, handling custom errors, and calculating function selectors.
