# 如何跨链 – 在 EVM 之间

在 Ethereum 和 BNB 链等 EVM 链之间跨链

{% hint style="success" %}
**EVM：** EVM 链是使用以太坊虚拟机（Ethereum Virtual Machine）来运行兼容以太坊的智能合约和 dApp 的区块链。例如 Ethereum、BNB 智能链等。
{% endhint %}

3. 通过网络选择器选择你的**源**链和**目标**链

4. 输入你想发送的金额，并从下拉菜单中选择代币

* **提示：** 发送前请务必仔细核对代币合约地址！

5. 选择**接收的代币** – 在某些代币符号相同的情况下（例如 USDC / USDT），会出现不同的变体供你选择

* **提示：** 将鼠标悬停在代币上或点击链接，以核实代币名称和地址

6. 检查"You Receive"（你将收到）部分，确认所有详情均正确

* PancakeSwap 会根据你的源链和目标链从多个跨链桥提供商中进行选择。
* 各提供商在费用、处理时间和可能的限制方面有所不同——这些都会清楚显示。

* 标签可帮助你比较各条路由：
  * **Best Return**（最佳回报）= 接收金额最高
  * **Fastest**（最快）= 转账时间最短

根据你的需求，使用这些标签来平衡速度与价值。

{% hint style="warning" %}
在你**第一次**通过某个跨链桥提供商进行交易时，系统会提示你批准代币转账（这是一次性操作）

* 在**第二次**交易时，只需点击"Send"，你的跨链转账即会开始
  {% endhint %}

7. 坐下来放松一下！大多数跨链转账只需几分钟即可完成。完成后，你的代币将出现在你的 Ethereum 地址中。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.pancakeswap.finance/chinese/kua-lian-qiao/bridging/evms.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
