# Transaction

The context of the current state-processing update.

## Declaration

```swift
@frozen struct Transaction
```

## Overview

Overview Use a transaction to pass an animation between views in a view hierarchy. The root transaction for a state change comes from the binding that changed, plus any global values set by calling withTransaction(_:_:) or withAnimation(_:_:).
