# Auctions

**How it works:**

* **$GRVE** will be used for auctions
* To create an auction, a **100 $GRVE burning fee** must be paid
* The auction has a time limit and an initial bidding price and you can choose the minimum bid increment. (*The minimum bid must equal the current bid plus the minimum bid increment*)
* If no users participate in the auction, the creator may request the return of the NFT (*The burning fee is not refunded*)
* If there are valid bids, when the auction expires, the creator can take the **$GRVE** of the winning bid; the winner of the auction can claim the NFT; those who bid without winning can take back their previous bids
* If a user places two bids because the previous bid was outbid, the **$GRVE** to be deposited will be equal to the value of the new bid minus the previous bid (*$GRVE already deposited*)

**Happy bidding!**

# Agent Instructions
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://croskulls-organization.gitbook.io/croskull/ecosystem/auctions.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.
