# Rome Bridge

Rome Bridge——一个独立的跨链桥和可集成 API，不涉及托管密钥。

Rome Bridge 有两部分：一个 **独立桥** 覆盖六条链，以及一个 **Bridge API** 任何应用都可以集成，以在自身 UX 中嵌入跨桥功能。它通过 CCTP v2（USDC）、Wormhole（ETH 进出；其他资产仅支持转出，前提是运营方已启用）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，而不是服务方的签名。API 负责协调，并可代付费用；真正的桥接在链上完成。

## 支持的链和资产

进入 Rome（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？请参阅 [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). 该 `?chain=` 参数用于选择目标 Rome 链。

## 集成 API

该 API 为公开接口。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`。请查看端点响应以了解当前通道集合和所需字段。

## 结算如何运作

链下 API 仅作为编排器和费用代付方。入金通过用户签名授权，以无信任方式在链上完成结算；出金则通过链上的桥接合约处理。任何步骤都不会在未经用户签名的情况下扣除用户资金。

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