# AMM and fees

**Available now.**

**LaunchAMM** is a minimal AMM for token/ETH pools on Robinhood Chain Testnet. Protocol fee configuration is owned by the timelock.

For the full fee table (launch fee, caps, freeze-at-creation, zero supply take), see [Fees and economics](/token-launch/fees-and-economics.md).

## Pool mechanics

| Pair            | Launch token and ETH                                                                           |
| LP fee          | 0.30%                                                                                          |
| Protocol fee    | Optional, opt-in. Default 20 bps. Hard-capped at `MAX_PROTOCOL_FEE_BPS = 50`.                  |
| Protocol split  | 70% project / 30% platform (`PROJECT_SHARE_BPS = 7000`), enforced in bytecode                  |
| Fee destination | [FeeSplitter](/token-launch/contract-addresses.md) (never an EOA as the platform sink)         |
| Existing pools  | Protocol fee rate **frozen at pool creation**; changing the default does not rewrite old pools |

| Role      | Platform fee destination; payees set via timelock; permissionless audited distributions |

## What you can change (with delay)

AMM knobs such as the default protocol fee sit behind the [TimelockController](/token-launch/governance.md). There is no instant admin switch on production-bound parameters. Testnet `minDelay` is 300 seconds.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.canhav.com/token-launch/amm-and-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.
