# Rome Bridge

Rome Bridge 有两个部分：一个 **独立桥** 覆盖六条链，以及一个 **Bridge API** 供任何应用集成，将跨链桥接嵌入其自身的用户体验中。它通过 CCTP v2（USDC）、Wormhole（ETH 和通用资产）以及 Solana 原生通道转移资产。

它不持有 **托管密钥** ——结算始终需要用户自己的签名，从不需要服务方签名。API 负责编排，并且可以代付费用；真正的桥接在链上完成。

## 支持的链和资产

进入 Rome（Martius、Hadrian），通过四条通道—— `CCTP`, `Wormhole`, `spl-bridge`, `原生`:

| 资产           | 通道              | 源链                                                                                            |
| ------------ | --------------- | --------------------------------------------------------------------------------------------- |
| **USDC**     | CCTP            | Ethereum Sepolia, Arbitrum Sepolia, Base Sepolia, Polygon Amoy, Avalanche Fuji, Monad Testnet |
| **ETH**      | Wormhole        | Ethereum Sepolia                                                                              |
| **SPL / 原生** | spl-bridge / 原生 | Solana                                                                                        |

实时列表始终位于 [`/v1/chains`](https://bridge-api.devnet.romeprotocol.xyz/v1/chains)。需要测试代币？请参见 [水龙头](/zh/zi-yuan/faucets.md).

## 单独使用

打开桥接界面： [bridge-api.devnet.romeprotocol.xyz](https://bridge-api.devnet.romeprotocol.xyz/?chain=200010)。 `?chain=` 参数用于选择目标 Rome 链。

## 集成 API

该 API 是公开的。列出支持的链和通道：

```bash
curl https://bridge-api.devnet.romeprotocol.xyz/v1/chains
```

报价和路由请求使用 CAIP-2 `sourceChain`。请参阅端点响应以了解当前通道集合和所需字段。

## 结算方式

离链 API 仅充当编排器和费用代付方。入站转账通过用户签名的授权在链上以无需信任的方式结算；出站提取则通过链上桥接合约完成。任何步骤都不会在没有用户签名的情况下扣除用户资金。

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 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.rome.builders/zh/rome-shang-de-ying-yong/bridge-api.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.
