# One Click 代发交易

适用于 API Key 已绑定用户钱包地址，并由服务端代发交易的场景。

## 授权流程

```mermaid
sequenceDiagram
    participant 用户
    participant 客户端
    participant API
    participant 链上

    客户端->>API: GET /1ct/status
    API-->>客户端: { status: "disabled" }
    客户端->>API: POST /1ct/prepare { deadline }
    API-->>客户端: signPayload (EIP-712)
    客户端->>用户: 请求签名
    用户->>客户端: signature (65 bytes)
    客户端->>API: POST /1ct/enable { signature, deadline }
    API->>链上: delegateBySig
    API-->>客户端: { status: "enable" }
```

## 操作步骤

1. 调用 `GET /api/v1/1ct/status` 查看授权状态。
2. 未启用时，调用 `POST /api/v1/1ct/prepare` 获取 `signPayload`。
3. 用户钱包对 `signPayload` 进行 **EIP-712 签名**。
4. 调用 `POST /api/v1/1ct/enable` 提交签名并开启 One Click。
5. 调用 `/send` 系列接口完成具体操作。

## 可用的 Send 接口

| 操作类型 | 接口                                     |
| ---- | -------------------------------------- |
| 下单   | `POST /api/v1/orders/send`             |
| 撤单   | `DELETE /api/v1/orders/{orderId}/send` |
| 入金   | `POST /api/v1/cash/deposits/send`      |
| 出金   | `POST /api/v1/cash/withdrawals/send`   |

## 入金前置要求

> \[!IMPORTANT] 用户钱包需先对现金 token 执行 ERC-20 `approve`。

授权 owner 为实际入金用户地址：

* 使用 `/cash/deposits/send` 时为 API Key 绑定的 `userAddress`
* 使用 `/cash/deposits/calldata` 自行提交时为交易发起钱包地址
