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.

Pool mechanics

Item	Detail
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 (never an EOA as the platform sink)
Existing pools	Protocol fee rate frozen at pool creation; changing the default does not rewrite old pools

FeeSplitter

Item	Detail
Ownership	Timelock
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. There is no instant admin switch on production-bound parameters. Testnet minDelay is 300 seconds.
