# Presale Page

**Operations**

* **User Participation**: Users enter the amount of BNB to participate in the presale. Each user can participate multiple times, but the total participation cannot exceed the maximum purchase amount.
* **Admin Settings**: Admins can set the sale type (public, whitelist), modify start/end times, edit token details, and cancel the presale.
* **Refund**: If the soft cap is not reached by the end time, users can actively request a refund.
* **Presale Completion**: After the end time, the admin can click the presale 【Complete】 button to automatically add liquidity, burn/refund unsold tokens, and distribute the remaining BNB to the admin. Users can claim their tokens.
* **Whitelist Management**: Admins can batch add or remove whitelist addresses.
