# 用户操作

用户在 `RWAEarnPool` 上调用方法进行认购和赎回，在 `USDT` 代币上进行一次性 `approve` 操作后——池通过 `transferFrom` 拉取资产，因此第一次 `deposit` 在没有授权的情况下会被回退。需要授权的支出者是 `RWAEarnPool`。

## 流程

1. 用户调用 `RWAEarnPool.deposit`。池从调用者那里拉取 `USDT` **直接到 `RWAAdapter`**，因此它不持有任何存入的本金。它唯一持有的资产余额是通过 `finishWithdraw` 由适配器推回的可提取流动性，等待被认领——不要将池的余额视为 AUM。
2. 池将份额铸造给 `receiver` 参数（不一定是 `msg.sender`）。
3. `RWAAdapter` 进入外部金库流程。
4. 对于赎回，用户首先请求提款，然后在资金可用时进行认领。

| ------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `deposit(uint256 amount, uint256 shares, address receiver)`         | 将份额铸造给 `receiver` 并将资产从 `msg.sender` 转移到适配器。接受 **amount** 或 **shares** 中的一个——传递您想指定的一个，另一个传 `0`；池从第一个推导出第二个。需要注意的两个门槛：一个是 **最低存款**（`minDeposit`，以资产单位表示），低于此值的存款会被回退——小额测试存款将失败；另一个是接收者白名单，当集合为空时是 **开放的**；一旦管理者填充了它，未列出的存款和份额转移将被回退。在假设之前，请阅读 `minDeposit()` 和 `getWhiteList()`。 |
| `requestWithdraw(uint256 amount, uint256 shares, address receiver)` | 与 `deposit` 相同的双重 `amount`/`shares` 约定——传递一个，另一个传 `0`。以份额形式收取提款费（转移给费用接收者——读取 `withdrawFeeRate()`，其缩放为 `1e18`，因此 `1e15` 是 0.1%），从 `msg.sender` 中销毁剩余部分，并记录接收者和金额——该金额是从减少的份额数量重新推导的，因此排队的支付低于简单的 `convertToAssets(shares)`。                                                       |
| `claimWithdraw`                                                     | 在 `RWAEarnPool` 中适配器提供的流动性可用后，将资产转移给接收者。                                                                                                                                                                                                                                          |

## 提款生命周期

提款是异步的。结算阶段运行在 **外部金库的赎回周期** 上，而不是合同强制执行的时间表上，因此没有链上截止日期，未决请求变得可认领。轮询可认领的流动性，而不是假设固定的延迟。利息随着报告进入份额净值，因此份额的价值在持有期间增长，而不是单独支付。

# 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.bsc.lista.org/zh-cn/kai-fa-zhe-zhuan-yong/rwa/user-operations.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.
