# Send Transaction

接入前请查看[节点地址、Account UUID 与额度](/node1-docs/documentation/zh/robinhood/robinhood-landing.md)。

在本地为 Robinhood Chain（Chain ID 4663）签名交易。支持 EIP-155 保护的 legacy、EIP-2930 type-1 和 EIP-1559 type-2 交易。私钥应保留在你自己的钱包或签名服务中。

使用 POST / 和 JSON-RPC 方法 robinhood\_send\_raw\_transaction，将已签名交易的十六进制数据作为 params 数组中的唯一参数。此服务不负责交易签名，也不提供通用链上 RPC。

## cURL 示例

```bash
curl -X POST 'https://robinhood-ohio-2b.node1.me/' \
  -H 'Authorization: Bearer <ACCOUNT_UUID>' \
  -H 'Content-Type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"robinhood_send_raw_transaction","params":["0x<SIGNED_TRANSACTION>"]}'
```

本示例使用 Ohio 2B；使用 Ohio 2C 或 SFO3 时，将请求 URL 替换为[服务概览](/node1-docs/documentation/zh/robinhood/robinhood-landing.md)中的对应地址，方法和参数相同。将 UUID 和交易占位符替换为你自己的数据。请使用完整的已签名交易十六进制数据，替换后不要保留尖括号，且仅保留一个 0x 前缀。

## 接收回执

新版节点在本地校验、鉴权、限流和入队后立即返回 HTTP 202，响应头为 `x-node1-submission-state: queued`。不等待排序器回应；`result` 哈希只表示本地已接收，不表示已发送完成或上链。

单笔请求计为 1 笔；普通付费账号与 plain text、batch 共用[按交易笔数计算的额度](/node1-docs/documentation/zh/robinhood/robinhood-landing.md)。

响应提示 `message` 为 `"Successfully forwarded"`。单笔 JSON-RPC 和纯文本响应将其放在顶层；batch 将其放在每个 `queued` 交易项中。该字段仅用于展示，服务仍在本地入队后返回 HTTP 202，不等待网络写出或排序器确认，也不表示交易已上链。客户端应依据状态、哈希及错误字段处理响应，不要根据提示文案判断上链成功。

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x<TRANSACTION_HASH>",
  "message": "Successfully forwarded"
}
```

## 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://node1.gitbook.io/node1-docs/documentation/zh/robinhood/robinhood-landing/robinhood-send-transaction.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.
