Project: PepesFamily launchpad v5: creator-chosen split of the 3% fee
Project: PepesFamily launchpad v5: creator-chosen split of the 3% fee Repo: github.com/0xtenang/PepesFamily (commit 6256451) Scope: contracts/src/PepesFamily.sol, contracts/src/PepesFamilyLens.sol, contracts/src/PepesFamilyRouter.sol (new launchWithSplit; launch uses the default split). PadToken.sol is unchanged from v4 (audits ec4e3ea7, b803125e, 348884ab, cbe092d6). Tests: contracts/test/PepesFamily.t.sol, contracts/test/Fork.t.sol Chain: Robinhood Chain (4663), Uniswap v4 What changed from v4 Every swap still pays 4%, with a fixed 1% protocol fee in IMD. The other 3% is split as the creator chose at launch: FeeSplit{creatorBps, holderBps, burnBps}, summing to 300, in steps of 50, with creator ≤ 200, immutable per token. Presets: 0/300/0 (default), 200/100/0, 0/0/300, or custom. IMD fee = (400 − burnBps) bps of the trader’s gross IMD: 100 protocol, creatorBps to pendingCreatorFees[token], holderBps to pendingHolderFees[token]. Creator fees: collectCreatorFees(token) (anyone) pays creatorPayout[token]. setCreatorPayout can only be called by the current payout address. Burn = burnBps of the trader’s gross token amount, taken in the token and sent to 0x…dEaD via poolManager.take during the swap. Where each fee is charged: the specified currency’s fee in beforeSwap (positive specified delta), the unspecified currency’s fee in afterSwap (hook delta), so a swap can pay IMD fees and burn together. Transient slots FEE_SLOT / BURN_SLOT pass the before-swap amount to afterSwap. getTokenInfo / getTokens moved to PepesFamilyLens (deployed by the launchpad, lens()) to stay under the contract size limit. launch / launchFor were replaced by launchWithSplit / launchForWithSplit. Please check Fee math for all four swap kinds (exact-in/out × buy/sell) and both currency orders: protocol 1%, creator and holder shares of the gross IMD, burn share of the gross tokens. Is there any rounding or partial-fill case where a trader pays more or less than stated, or where toInt128 reverts unexpectedly? Is taking tokens to 0x…dEaD from inside beforeSwap / afterSwap always settled correctly? Consider swaps with a price limit that only partly fill, and very small or very large amounts. Claim backing: the launchpad’s ERC-6909 IMD claims must always equal pendingProtocolFees + Σ pendingHolderFees + Σ pendingCreatorFees. Creator fees: can anyone redirect or block them? Any reentrancy in collectCreatorFees or the unlock callback? Split validation: can a token end up with a split that breaks the rules, or a creator above 2%? Regressions: anything that breaks v4 guarantees (locked liquidity, 4% on every router, the flash-borrow guard, holder expiry, router compatibility, the ETH router’s hookData).
