# Fees and economics

**Available now** on Robinhood Chain Testnet. Values below are verifiable on-chain. Prefer reading live contract state for the current `launchFee` and `defaultProtocolFeeBps`; this page records the design and the last documented calibration.

## Zero supply take

CanHav takes **0% of token supply**. Enforcement is the absence of a mint function after initialize on the launch token, not a soft policy. See [Contract guarantees](/token-launch/contract-guarantees.md).

Allocation sales take **0% platform cut** of sale proceeds (fee-free sales contract).

## Fee switches

Factory pause stops new launches. It is an emergency control, not a fee switch. Unpause waits on the timelock. See [Governance](/token-launch/governance.md).

## Existing pools are frozen at creation rate

When you create a pool and opt into the protocol fee, the pool stores its `protocolFeeBps` at creation time. Changing `defaultProtocolFeeBps` later does **not** rewrite existing pools. New pools pick up the new default; old pools keep the rate they were created with.

Verify in [`LaunchAMM`](https://explorer.testnet.chain.robinhood.com/address/0xDd070b1f8e000D27491A3d38543ef0D72C758Df4): createPool freezes fee; `setDefaultProtocolFeeBps` is owner-only (timelock).

## Fee destination

Platform protocol fees route to [FeeSplitter](https://explorer.testnet.chain.robinhood.com/address/0x9FDFae007b65d4c8F3CCA6AC242E3f141eC9DA18), never to an EOA as the platform sink. Payee changes are timelocked.

## How to verify independently

1. Open each address on the [explorer](https://explorer.testnet.chain.robinhood.com).
2. Read `launchFee` and `MAX_LAUNCH_FEE` on the factory.
3. Read `defaultProtocolFeeBps`, `MAX_PROTOCOL_FEE_BPS`, and `PROJECT_SHARE_BPS` on the AMM.
4. Read `minDelay` on the TimelockController.
5. For a live pool, inspect its stored `protocolFeeBps` and confirm it does not change when the default changes.

Product UI: `/launch/governance` surfaces economic terms while you build on testnet.

# 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/fees-and-economics.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.
