# Overview

{% hint style="warning" %}
The **Prover private key** in the keys.yml file is encrypted using the Advanced Encryption Standard (AES), and therefore cannot be directly imported into the Qrim Wallet.\
\
If you want to bridge $QUIL to $wQUIL, please create an address with both the peerPrivKey and Prover private key using Qrim Wallet, and then send $QUIL to this address for bridging
{% endhint %}

\

[Qrim Bridge](https://wallet.qrim.io/bridge) enables seamless transfers between Quilibrium to Ethereum assets, providing Qrim users with a fast, efficient, and convenient cross-chain token transfer service.

## 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://qrim.gitbook.io/qrim/qrim-bridge/overview.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.
