# 手续费和路由

<figure><img src="https://raw.githubusercontent.com/pancakeswap/pancake-document/en/.gitbook/assets/image%20%2861%29.png" alt=""><figcaption></figcaption></figure>

在 Exchange V3 中，默认情况下，PancakeSwap Smart Router 将利用来自 V3、V2、StableSwap（BNB Chain）以及 AMM 和 Market Maker（BNB Chain 和 Ethereum）的流动性来执行交易，并为交易者找到最优价格。

但是，用户始终可以通过选择路由应利用哪些流动性来源，以及启用或禁用多跳（multihops）和拆分路由（split routing），来自定义自己的交易。

要查看你当前的兑换将收取多少交易费用，请查看兑换详情部分中的 “Fee” 部分。

要查看你的交易当前路由所经过的池类型和费率档位，请查看 “Route” 部分。

要了解更多详情，请点击放大镜图标以调出完整的交易路由显示。

### **自定义流动性来源**

在 “Customize Routing” 界面的顶部，你可以选择路由在为你的交易进行路由时应使用哪些流动性来源。要调出此界面，你可以：

* 点击交易路由显示底部的 “Customize Routing”。
* 点击兑换界面中的齿轮图标，然后点击底部的 “Customize Routing”。

默认情况下，所有流动性来源均已启用，Smart Router 将充分利用 PancakeSwap 内所有可用的流动性。

请注意，路由不会在 AMM 流动性池和 MM Market Maker 之间进行交易路由。当你的交易由 MM Market Maker 执行时，它不会经过任何 AMM 流动性池。

你可以点击右上角的 “Reset” 按钮将配置重置为默认值。

### **自定义路由偏好**

在 “Customize Routing” 界面的底部，你可以通过启用或禁用多跳和拆分路由来自定义你的路由偏好。

多跳允许代币在多个流动性池之间通过多次跳转进行兑换，以达成最优交易。关闭它将把交易限制为直接兑换，这可能导致更高的滑点甚至资金损失。

拆分路由使代币兑换能够被拆分为多个路由，以达成最优交易。关闭它将限制交易只能通过单一路由执行，这可能导致效率低下或更高的滑点。

{% hint style="warning" %}
当你的交易由于自定义的交易配置而无法执行时，将出现一条警告，你可以点击 “Check your settings” 快速调出 “Customize Routing” 界面。或者选择 “Reset to default” 快速将你的配置重置为默认值。

## 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.pancakeswap.finance/chinese/jiao-yi/pancakeswap-exchange/fees-and-routes.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.
