Contract addresses
All addresses below are verified on-chain. Merry Men contracts are
Blockscout-verified; Uniswap V3 and WETH addresses were confirmed via eth_call
linkage (PositionManager.factory() / .WETH9() and
factory.feeAmountTickSpacing(10000) == 200).

The locker and treasury are created by the factory itself. The factory, locker, treasury, delegate, and the first launch token are Blockscout-verified; subsequent launch tokens auto-verify (identical bytecode).

A note on routers
Section titled “A note on routers”Testnet and mainnet ship different Uniswap routers with different ABIs. This is the single most common integration mistake:
| Network | Router to use | exactInputSingle shape |
Selector |
|---|---|---|---|
| Mainnet (4663) | SwapRouter02 0xcaf6… |
No deadline | 0x04e45aaf |
| Testnet (46630) | SwapRouter 0xf091… |
Deadline in struct | 0x414bf389 |
Encode the swap for the wrong variant and it reverts. On both networks the
UniversalRouter cannot route Merry Men pools (factory / init-code-hash
mismatch), so never route swaps or buybacks through it.
Protocol configuration
Section titled “Protocol configuration”The deployed factory generation uses:
| Parameter | Value | Meaning |
|---|---|---|
feeTier |
10000 |
1% Uniswap V3 fee tier |
creationFeeWei |
0 |
No launch fee |
protocolFeeBps |
5000 |
50% creator / 50% protocol on collected fees |
BUYBACK_SHARE_BPS |
3000 |
Of the protocol share: 30% buyback / 70% ops |
Invariants
Section titled “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. |
