Project: PepesFamily launchpad v4, re-check after audit ec4e3ea7
Project: PepesFamily launchpad v4, re-check after audit ec4e3ea7 Repo: github.com/0xtenang/PepesFamily (commit 2097cf2) Scope: contracts/src/PepesFamily.sol, contracts/src/PadToken.sol, contracts/src/PepesBuyback.sol Tests: contracts/test/PepesFamily.t.sol, contracts/test/PepesBuyback.t.sol, contracts/test/Fork.t.sol Changes since ec4e3ea7 Finding 1: PepesBuyback adds a price guard. It records the pool sqrtPrice after each buyback (at deployment before the first) and only buys while the $PEPES price is ≤ 2% above it + 2% per day elapsed (priceRiseBps, allowedPriceRiseBps). Your proof scenario is test_pacedFrontRunStallsTheBuyback. Finding 2: burns the whole $PEPES balance. Finding 3: the hook calls PadToken.markActive(trader) on every buy. trader is the router-reported user when sender == router, otherwise tx.origin. The pad is the only caller allowed. A transfer the recipient didn't start counts as activity only if amount × 10 ≥ recipient's prior balance. ACTIVITY_MIN is removed. Finding 5: the buyback constructor resolves the $PEPES pool through pepesRouter.pad().poolKey(pepes) and requires an initialised IMD/$PEPES pair. Otherwise it reverts with BadWiring. Findings 4, 6, 7: comments and README corrected, and tests added. Please check Can the price guard be gamed? For example: pushing the price down before a buyback to set a low reference, stalling buybacks forever (griefing), or a profitable series within the 2%/day allowance. Is using tx.origin in markActive safe? Can anyone make a buy mark another wallet active? Any problem with markActive being called during afterSwap? Does the 1/10-of-balance gift rule have edge cases (self-transfers, transfers from excluded accounts, first receipts)? Did any fix break v3 guarantees or the earlier findings?
