# Bridge

RAKE's supported bridge action and the source-defined assets and execution constraints.

## Bridge

Bridge brings ETH from outside into Robinhood Chain. It does not provide a general two-way bridge.

```
@rake_agent bridge 0.05 ETH to robinhood
```

### Direction

```
Outside
    ↓
Robinhood Chain
```

### Execution flow

```
ETH outside Robinhood
    ↓
Bridge command
    ↓
Echo confirmation
    ↓
ETH brought into Robinhood
```

Bridge requires Echo confirmation because it moves money. RAKE prepares the requested ETH amount for exact confirmation before execution. [Echo Confirmation](/rake/how-rake-works/echo-confirmation.md) defines the full confirmation rules.

### Boundary

**Supported**

* Bring ETH from outside into Robinhood.

**Not supported**

* Bridge out of Robinhood.

## 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.rakelaunch.xyz/rake/trading-and-utility/bridge.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.
