# Fair Launch Buy-Back Option

The fair launch buyback function is an optional feature that allows the project owner to use a portion of the funds raised to buy back tokens and burn them. This function is only available for fair launches, and you can choose to enable or disable it during the fair launch creation process.

* Buyback Percentage (%): Enter the percentage of raised funds that should be allocated to the buyback. (The sum of buyback percentage and liquidity percentage should be greater than 51%.)
* Amount Per Buyback: The default value is 1 BNB. This represents the amount of raised funds that will be used for buying back tokens and burning them per buyback.
* Minimum Buyback Delay: The default value is 1 hour. After this duration from the last buyback, the owner can click on the buyback button to initiate a new buyback.
* Maximum Buyback Delay: The default value is 6 hours. After this duration from the last buyback, users can also click on the buyback button to initiate a new buyback.

Once you have successfully created the fair launch you will be able to see the Buy-Back information. The first buy-back can be performed one hour after you finalize the fair launch. Investors can start buy-back function by clicking the buy-back button every 6 hours.

## 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://oni.gitbook.io/oni.exchange/fair-launch/fair-launch-buy-back-option.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.
