# 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.
