# Bridge assets to Udon

Before interacting with UdonFi, your assets need to be available on the Udon Chain. This requires a two-step bridging process unless your assets are already on Chromia.

{% stepper %}
{% step %}

### Bridge step

BNB Smart Chain → Chromia Economy Chain using Chromia Vault

Use this step if your tokens are on BNB Smart Chain and need to be moved to the Chromia Economy Chain first.
{% endstep %}

{% step %}

### Bridge step

Chromia Economy Chain → Udon Chain using the UdonFi dashboard

This step moves assets from Chromia Economy Chain into Udon Chain.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
If your tokens (e.g., CHR, ALICE, or D) are already on the Chromia Economy Chain, you can skip the first step and bridge directly to Udon.
{% endhint %}

This guide uses CHR bridged from BNB Smart Chain as an example. Other assets follow the same process unless stated otherwise in-app.

# 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 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://udonfi-1.gitbook.io/udonfi-docs/user-guide/bridge-assets-to-udon.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.
