# Stage 6

**Status: Testing underway**

Panther’s test network is now live on Amoy, Polygon’s test network, and can be accessed [here](https://docs.pantherprotocol.io/docs/product-and-technological-components/product-versions/v1-testnet?ref=blog.pantherprotocol.io). Due to this network change, users will need to complete the onboarding process again and activate their test zAccount. Users who are using their old accounts, however, will not have to go through PureFi credential process again and will be moved directly to the account activation. This is a one-time activity required to access Panther.  

> For the current dApp, see the [entrypoint](/docs/panther-core/testnet.md). Note that, each stage's entrypoint is deprecated in favor of the next stage.

### Functionality

Stage 6 introduces two core functionalities with some extra details on the impact to UTXO Selection:

* [Fees](#fees) 
* [AMM Refilling with Protocol Fees](#amm-refilling-with-protocol-fees)
* [Limited Subsidy Rewards](#limited-subsidy-rewards)

#### Fees Testing

This release introduces the mechanism for charging different types of fees within the simulated testnet, including Protocol Fees, Network Gas Fees, KYT fees and KYC Fees. All simulated fees are paid from the Panther Gas account in tZKP.

#### AMM Refilling with Protocol Fees Testing

Simulated protocol fees collected during the testing will be deposited into the AMM’s pool of tZKP.

#### Limited Subsidy Rewards Testing

The production (mainnet) version of Panther Protocol may include feature that will allow to introduce additional rewards to partially or fully compensate costs like Network Gas Cost, KYC, KYT and Miner fees, in service of encouraging use of the platform. Stage 6 of our testnet simulates this feature for testing purposes.

**Note:** This feature is designed to cover only tZKP-nominated fees, and will not involved test MATIC or other native test network tokens unless using the relayer service.

## 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.pantherprotocol.io/docs/changelog/overview-1/stage-6.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.
