# Network Fee

Every application is associate with a wallet address (account address on Hypersign Blockchain) and the private key for that wallet address is managed by Entity Studio API server for the application via an encrypted data vault (read security section for more details). 

Since many SSI APIs are on-chain activities, `$hid` token is required to pay for transaction fee for those on-chain activities. 

### Application Wallet

Go to the developer dashboard and click on **Edit** icon of your application's card.  Right slider will be opened where you can see details of your wallet.

## 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.hypersign.id/hypersign-developer-dashboard/developer-dashboard/network-fee.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.
