Contract addresses

All addresses below are verified on-chain: Merry Men contracts are Blockscout-verified, and the cross-contract wiring (factory to hook, gate, and locker) was confirmed via eth_call linkage.

This page covers the current generations. Every retired generation still runs and its addresses still matter for the coins on it: see Earlier generations.

Mainnet: Robinhood Chain (4663)

Generations, newest first. A coin trades against the generation it launched under forever, so all of these stay live simultaneously.

Gen-VG: verified launches with launch gates (newest)

Contract	Address
`LaunchpadFactoryV4G`	`0x63d7B20c8824144329D56e23b1d58d414fC57d3d`
`MerrymenHookVG` (fees + burn + gate enforcement)	`0xd57C56c6d47DC28e95a7950704c0F3fb1f4BA0CC`
`LpLockerV4` (gen-VG)	`0x79eE8875892a291CA74fb7bBeCbb4A83DBe080E0`
`LaunchAttestationGate`	`0x4e0f0B2FF883C719164ac98E8f2CFd8067C68a2e`
`PriorityLaunchGate` (game / verified windows)	`0x959A161752027a809db4e5Bc869B9F246Ff4fbfD`
`PriorityRouter` (priority-round buys)	`0xfa68431998EB06574BAca27308b5e6BF86b3f3C4`
`VerifiedRouter` (verified-window trades)	`0xE237A3F0DBd3FDE8Fbb9C416d7A639852B6C84Fc`

Every entrypoint on this factory requires a launch attestation (there is no unverified createToken), carries the creator’s sell-curve preset, and the frozen entrypoints arm a Game or Verified-only opening window atomically with the launch. Fee model: 0.25% buys, decaying sell fee with a burned leg; 0.10% of volume to the house, 0.15% to the creator. See Fees. Not audited.

Gen-V: verified launches (deployed 2026-08-09)

Contract	Address
`LaunchpadFactoryV4V`	`0xcFe0a44EA5b06B7d2b8E22ab0B3c80E64Baa5f64`
`MerrymenHookV`	`0x93F11A912c9E0A9DfF7Cd2C3E9e7E7bbE415e0cC`
`LpLockerV4` (gen-V)	`0x54D6398AACF402083f6e9b6D5b59551cA706cB12`
`LaunchAttestationGate`	`0x19503a5780e62B500b7fB700202E38106FEa1C95`

Gen-VG’s fee model without the gates: verified at mint, one fixed sell curve (5% → 1%). Not audited.

What v4 changes for an integrator

Both generations launch into Uniswap v4 pools quoted in native ETH, not V3 TOKEN/WETH pools:

There is no pool address. A v4 pool is identified by its 32-byte PoolId, and the full PoolKey is emitted in TokenLaunchedV4 because a PoolId is a one-way hash you cannot invert. GeckoTerminal and DexScreener both key v4 pools by the PoolId.
The pool’s LP fee is zero. PoolKey.fee carries the dynamic-fee flag (0x800000), not a tier; do not read it as a rate. The hook charges the fee instead.
Hook addresses are CREATE2-mined so their low bits encode v4 hook permissions.

Platform-wide

Contract	Address
`RewardsDistributor`	`0xb81Db9E11Ce95482Ce33cBf16317E22A8ea0c558`
`FeeStreamMarket`	`0x7d612aac82cfe054ad5bd7c77eecae457f618d6e`

Lockers and gates are created or wired by their factory. The factories, lockers, and first launch tokens are Blockscout-verified; subsequent launch tokens auto-verify (identical bytecode).

Protocol configuration

All immutable; creationFeeWei = 0 (no launch fee):

Parameter	Value	Meaning
`buyFee`	`2500` ppm	0.25% quote fee, both directions
`opsFeeBps`	`4000`	the house’s cut of that: 0.10% of volume; the creator’s 0.15%
`sellPreset(i)`	3 fixed curves	sell decay to the 1% floor (see Fees)
`maxFee`	`100000`	10% hard ceiling on any rate

Earlier generations’ parameters are on their page.

Invariants

The core contracts are built and tested to hold these invariants (Foundry invariant + fork tests, 100% line/branch/function coverage on the core three):

#	Invariant
L1 Custody	No code path transfers a locked position NFT out of the locker. Only fees can be extracted.
L2 Fee conservation	`claimFees` pays the protocol share to treasury and the remainder to the creator, per collected asset; position principal is never moved.
L3 Single-sided seed	Immediately after `createToken`, the position holds token-only liquidity and zero WETH. Enforced in-contract; fuzzed across both address orderings.
L4 Fixed supply	Total supply equals the launch amount forever; no mint path exists after construction.
L5 Launch atomicity	`createToken` fully completes or reverts, never a half-launched token with unlocked or WETH-contaminated liquidity.
L6 Fee accounting	Creation fee forwarded to treasury; any `msg.value` excess refunded; the factory holds no residual ETH.

Onchain events: events emitted by these contracts.
Reading token state: reads against the factory, pool, and token.
