# Bridge In

The built-in bridge is powered by [**Relay**](https://relay.link) — an intents-based bridge where professional solvers front you the funds on the destination chain. Transfers usually land in **seconds**.

## Supported routes

| From     | Assets    | To                     |
| -------- | --------- | ---------------------- |
| Ethereum | ETH, USDC | ETH on Robinhood Chain |
| Base     | ETH, USDC | ETH on Robinhood Chain |
| Arbitrum | ETH, USDC | ETH on Robinhood Chain |

Everything lands as **ETH on Robinhood Chain** — the asset you need for gas, launches and trading. USDC is swapped en route automatically.

## How it works

1. Pick the origin chain and asset, enter the amount — you'll see the exact amount you'll receive, the relayer fee and an ETA before confirming.
2. Approve the transaction in your wallet (the app switches your wallet to the origin chain automatically).
3. Watch the transfer progress live: **Signed → Source confirmed → Relaying → Landed**. Your history is kept on the page.

## Fees & timing

Relay charges a small relayer fee (shown upfront in the quote). Typical delivery is under 30 seconds from Base/Arbitrum and a few minutes from Ethereum mainnet.

## 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.loopad.fun/product/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.
