# Bridge

## To bridge your Arkhante S01 pack

The packs from the first season of Arkhante on Opensea ([Legacy Packs](https://opensea.io/collection/arkhante-booster-premium-pack), [Premium Packs](https://opensea.io/collection/cross-the-ages-arkhante-booster-premium-pack-1)) are on the Polygon blockchain. Once purchased, to be opened and played, they must be transferred to the IMX blockchain. To do this, a bridge is used.

### How to perform the bridge:

Once the bridge is completed, your Premium Pack will be on the ImmutableX blockchain. Therefore, it will no longer be possible to sell on Opensea where you originally purchased it.

For resale, if desired, you can use the dedicated [CTA marketplace](https://www.crosstheages.com/portal/marketplace/products). To access it, simply go in-game to the Chest section.

## 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://whitepaper.crosstheages.com/guide/en/cta-portal/cta-portal-overview/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.
