# Zip/Unzip Fees

<figure><img src="/files/RjX0JGGs3fz0TKEyjcUp" alt=""><figcaption></figcaption></figure>

Zipping and unzipping assets on Zipper incurs **no additional service fees** beyond the **network transaction costs** required to process deposits and withdrawals.

📌 **Zipper does not charge percentage-based fees -** users only pay the necessary blockchain gas fees to facilitate the transfer of assets.

### **How Are Fees Calculated?**

* **Deposit (Zip):** Users pay the network fee required to send their assets to the Zipper vault on the original blockchain. Fabric Labs sponsors the network costs on Fabric for minting the zAsset and transferring to your user wallet.
* **Withdrawal (Unzip):** Users pay the network fee required to process the withdrawal and transfer the original asset to their destination address from the Zipper vault. Fabric Labs sponsors the network costs on Fabric for burning the zAsset.
* **Fees are dynamically calculated** based on **real-time network conditions** and are displayed before confirming a transaction.

## 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://docs.zipper.trade/getting-started/zip-unzip-fees.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.
