# FAQ

**What chain does Harmonic use?**

Harmonic runs exclusively on **Base**.

**Is it really gasless?**

Yes. Transactions are executed through x402 requests, no ETH required.

**How are tips paid?**

Tips are included by users when submitting trades and go directly to the validator who executes the transaction.

**Can anyone validate a transaction?**

Yes. Anyone can view the mempool, select a request, solve the CAPTCHA, and validate.

**What happens if two people try to validate the same trade?**

Only the **first** submitted validation is accepted. All others are rejected automatically.

**How much can I earn as a validator?**

Your reward depends on your $HARMO holdings and the trade amount + the bribe.

Example: Holding 0.5% of $HARMO supply and validating a $1,000 trade = **$10 USDC**.

**How is the treasury used?**

The Harmonic Treasury receives unclaimed validator rewards and funds protocol maintenance, marketing, and incentive programs.

**How to contact the team?**

Official updates and support are provided via **Twitter (@HarmonicPrtc)**.

## 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://harmonic-protocol-1.gitbook.io/documentation/faq.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.
