# 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. --- # Agent Instructions: 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.
