# Cross Chain Sales

Fjord Foundry now supports cross-chain sales using liquidity from any liquid token on any supported chain via LI.FI.

**Benefits include:**

* **Non-siloing of liquidity:** Access liquidity from various blockchains, reducing siloed liquidity. 
* **Greater uptake of Layer 2 solutions:** Lower fees by leveraging Layer 2 solutions while still accessing Layer 1 liquidity.
* **Simple and seamless UX:** Enjoy a straightforward and user-friendly experience for cross-chain participation.
* **Broader market participation:** Enable a diverse range of investors from different blockchain ecosystems to contribute encouraging greater participation. 

**How it works:**

In this example we will conduct a cross chain swap from Polygon to Base. As shown below, we are connected to the Polygon network.

The default setting will display the requested funding token from the project on the destination chain. To select a custom token or chain click the drop down box.

Next, choose the chain you wish to source the liquidity from. In this case we will select Polygon.&#x20;

Then select what token you wish to use to fund the purchase. In this case we will select the Matic token.&#x20;

Next you will have shown what your source blockchain and token. Here you can input how many tokens you wish to sell which will provide an expected output of the sale token on the destination chain.&#x20;

Click swap, and you will see a preview of the swap and a pop up in your wallet. Click 'confirm'. You may be required to do some approval transactions. <br>

Complete! Finalise the necessary transactions in your wallet and be sure not to increase gas settings and your purchase should be finalised. <br>

## 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://help.fjordfoundry.com/fjord-foundry-docs/for-sale-participants/fjord-features/cross-chain-sales.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.
