# Processing the rebalances and liquidations

### Introduction

In DeFi, a Keeper is an entity or system responsible for *automating on-chain actions* that cannot execute themselves. Since smart contracts on blockchains are passive, they require an external trigger—this is where Keepers come in.

While f(x) is a fully on-chain system, the Keeper is designed to actively monitor positions and initiate actions once certain conditions are met.

Maintaining an active Keeper community is critical for the f(x) Protocol. Therefore, we’ve written this document to help you understand some key concepts and processes related to Keepers.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://fxprotocol.gitbook.io/fx-docs/developers/processing-the-rebalances-and-liquidations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
