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.

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)	TokenFactory	0.0002 ETH (calibrated on v4)	MAX_LAUNCH_FEE = 0.05 ether	Factory owner = Timelock	Timelock minDelay (300 seconds on testnet)
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

Factory pause stops new launches. It is an emergency control, not a fee switch. Unpause waits on the timelock. See Governance.

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: createPool freezes fee; setDefaultProtocolFeeBps is owner-only (timelock).

Fee destination

Platform protocol fees route to FeeSplitter, never to an EOA as the platform sink. Payee changes are timelocked.

Timelock

Item	Value
Address	0x080cCDC07e2a0a5D11e9dDaA873ea68F540109ae
minDelay (testnet)	300 seconds
Owns	TokenFactory v4 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 the explorer.
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.
