Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.canhav.com/token-launch/fees-and-economics.md). # Fees and economics **Available now** on Robinhood Chain Testnet and Arbitrum Sepolia. Each chain has its own deployment and its own timelock, with the same values on both. 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 | Switch | Where | Current documented value | Hard cap | Who can change | Delay | | --------------------------------------------------------------------- | --------------------------------------------------- | --------------------------------------------------------------------- | ------------------------------------- | -------------------- | ------------------------------------------------ | | Launch fee (`launchFee`) | CurveLauncher (the `/launch` path) and TokenFactory | **0.0002 ETH** on both contracts, on both chains | `MAX_LAUNCH_FEE = 0.05 ether` | Owner = Timelock | Timelock `minDelay` (**300 seconds** on testnet) | | Snipe tax on curve buys | CurveLauncher | **20%** of buys in the first 60 seconds, held for the graduation pool | Immutable | Not an admin switch | N/A | | Trade fee on the curve | CurveLauncher | **0** | Immutable | N/A | N/A | | Default protocol fee for new opted-in pools (`defaultProtocolFeeBps`) | LaunchAMM | **20 bps** default | `MAX_PROTOCOL_FEE_BPS = 50` | AMM owner = Timelock | Same timelock delay | | LP trading fee | LaunchAMM | **30 bps (0.30%)** to LPs | Fixed in bytecode for the pool design | Not an admin switch | N/A | | Protocol fee split | LaunchAMM | **70% project / 30% platform** (`PROJECT_SHARE_BPS = 7000`) | Fixed constant | Not an admin switch | N/A | | Allocation sale platform cut | AllocationSale | **0** | N/A (no cut) | N/A | N/A | There is no creator trading fee and no fee paid to token holders anywhere in these contracts. Factory and launcher pause stop new launches (and curve buys); sells on the curve always work. Pause 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` on [Robinhood Chain Testnet](https://explorer.testnet.chain.robinhood.com/address/0xDd070b1f8e000D27491A3d38543ef0D72C758Df4) or [Arbitrum Sepolia](https://arbitrum-sepolia.blockscout.com/address/0x4EA372acAb7be21113f474CEd2B7b317019afeD3): createPool freezes fee; `setDefaultProtocolFeeBps` is owner-only (timelock). ## Fee destination Platform protocol fees route to that chain's FeeSplitter ([addresses](/token-launch/contract-addresses.md)), never to an EOA as the platform sink. Payee changes are timelocked. ## Timelock | Item | Value | | -------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | | Address, Robinhood Chain Testnet | [`0x080cCDC07e2a0a5D11e9dDaA873ea68F540109ae`](https://explorer.testnet.chain.robinhood.com/address/0x080cCDC07e2a0a5D11e9dDaA873ea68F540109ae) | | Address, Arbitrum Sepolia | [`0xeD66C31FFAC1C5dCf4f327536a7540B22DF2B5E1`](https://arbitrum-sepolia.blockscout.com/address/0xeD66C31FFAC1C5dCf4f327536a7540B22DF2B5E1) | | minDelay (testnet) | **300 seconds** on both | | Owns | On its own chain: CurveLauncher and TokenFactory admin surfaces, LaunchAMM admin surfaces, FeeSplitter payee config | | Production note | Anything closer to production should use 24h+ | ## How to verify independently 1. Open each address on its chain's explorer. See [Contract addresses](/token-launch/contract-addresses.md). 2. Read `launchFee` and `MAX_LAUNCH_FEE` on the launcher and the factory, and the curve immutables on the launcher (see [Bonding curve](/token-launch/bonding-curve.md)). 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` shows these terms live for either chain. See [Governance](/token-launch/governance.md). ## Related * [Contract guarantees](/token-launch/contract-guarantees.md) * [AMM and fees](/token-launch/amm-and-fees.md) (shorter overview) * [Governance](/token-launch/governance.md) * [Contract addresses](/token-launch/contract-addresses.md) --- # 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 by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.canhav.com/token-launch/fees-and-economics.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
