# PP 预付充值余额

PP 预付充值余额是 Jasper Vault 提供的预付功能。

用户可以提前充值专门用于支付永续合约保护（PP）费用的余额，从而在需要开启保护时更快完成支付。

***

### 为什么需要 PP 预付充值余额？

永续合约保护（PP）的价值往往体现在关键时刻。

例如：

* 突发行情
* 夜间持仓
* 重大数据发布前后
* 仓位浮亏扩大时
* 用户临时需要快速开启保护时

如果每次开启保护都需要临时完成支付，可能增加操作摩擦。

PP 预付充值余额的目标是：

**让用户提前准备好保护费用，在关键时刻更顺畅地开启永续合约保护（PP）。**

***

### PP 预付充值余额可以用于什么？

PP 预付充值余额通常用于支付永续合约保护（PP）费用。

它不应被理解为普通合约保证金，也不一定支持提现或转让。

具体规则以平台展示为准。

## 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://docs.jaspervault.io/zhong-wen-wen-dang/fei-yong-yu-gui-ze/pp-yu-fu-chong-zhi-yu-e.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.
