# Audit report > PondPad v1 security audit, round 3, area A2: $PONDPAD sale and market. PondPad is an IMD-paired token launchpad on Robinhood Chain (chain id 4663): Solidity 0.8.26, Foundry project in launchpad/contracts (cancun, via-IR), Uniswap v4 hooks. Other areas of the same commit are audited by separate jobs; stay on this one. > > READ FIRST, in this repository: > - launchpad/audit/THREAT-MODEL.md: actors and trust, the invariants (section 2), deliberate behaviour that is NOT a finding (section 3) and the severity scale (section 4).

At graduation the raise and 300M go to MarketController.launch, which opens PadMarketHook: our fork of POOL4's CappedBurnHook (upstream/CappedBurnHook.sol is the original; upstream/make_fork.py generates PadMarketHook.sol from it, so every change is in that script). Changes: IMD is currency0 ($PONDPAD address mined above IMD), ERC-20 quote instead of native ETH, dynamic LP fee 3% -> 1% over 7 days returned from beforeSwap, IMD-sized constants (cap floor 150M, decay 500k/day, 15% of trims to stakers). MarketController owns the hook forever; the only exit is migrate() (approved by the 7-day timelock, run by the team Safe, first 12 months). > Changed since round 1 (D-78): MarketController.launch measures what openMarket took; migration needs approveMigration (7-day sinkAdmin) and is run only by the migrator (team Safe), and the new hook inherits the placement floor, reference tick and cap (inheritGuards in make_fork.py; floor and cap only raised). > Changed since round 2 (D-79): IMD returned by an owner closeBackstop or a migration seed earns no keeper tip (untippedQuote, make_fork.py); a closed hook can't be reopened; migrate clears the old hook's allowances; sinkAdmin is immutable (no setSinkAdmin); PadSale.buyWith takes minImd, quoteBuy charges a completing buy only on the IMD it needs, graduation hands stray balances to the controller; new LiquidityReserve holds the 30M reserve until the market opens. > Look hardest at: > - Did make_fork.py change anything beyond its listed changes? Does the ETH -> ERC-20 quote conversion keep every settle/take/sync correct? Does the dynamic fee leak into cap, trim, burn, backstop or keeper-tip math? > - PadSale solvency, cap accounting across buyWith/sellFor and payment tokens, snipe tax timing, the completing buy's refund, graduation exactly once with the exact amounts and sqrt price. > - MarketController: can launch, collectFees, fundInventory, policy setters or migrate ever send pool assets to a wallet, open twice, change openedAt, or migrate into a hostile or already-open hook? > - Trim/burn/settleClaims/rebalance under adversarial keepers and outside routers (ordering, same block, partial settlement), PadBurner. > - Sell-side $PONDPAD fees and their split (collectFees -> FeeSplitter.distributeToken). > > Report only issues with a concrete path (who calls what, with which values, what goes wrong), with a Foundry proof where possible.

Nothing in the repository was changed or deployed. ## Findings ### 1. High: setCapFloor / setCapDecay are unbounded: the 48 h timelock can configure the market so ordinary round-trip trading trims the whole $PONDPAD position away (up to 30% of it to a wallet) `launchpad/contracts/src/MarketController.sol:194` ``` function setCapFloor(uint256 newFloor) external onlyOwner { hook.setCapFloor(newFloor); } function setCapDecay(uint256 tokensPerDay) external onlyOwner { hook.setCapDecay(tokensPerDay); } ``` MarketController forwards setCapFloor(newFloor) and setCapDecay(tokensPerDay) to PadMarketHook with no policy bound, and the hook accepts any floor (including 0) and any decay up to type(uint128).max (its comment says that bound only prevents an overflow). With capFloor = 0 and decay = uint128.max, one second of elapsed time is an unlimited ratchet allowance: _applyCap lowers inventoryCap to the pool's exact holdings after every buy, and every following sell is above the cap and trimmed in full (>= 70% burned, up to 30% to rewardsRecipient, which the 7-day sinkAdmin may point at any address, the listed power R1-A2-6; the proportional IMD leaves the position for the backstop ledger). Ordinary round trips then dissolve the market position, which the hook's own NatSpec (PadMarketHook.sol:62) warns about: 'Without a floor the ratchet compounds toward zero and the market ratchets itself out of existence'. This exceeds the admin bounds the project documents: ARCHITECTURE-v1 §5.6 'Can never: remove or move locked liquidity', D-21 (150M floor and 500k/day chosen as the non-aggressive bound), and invariant 11, whose sinkAdmin exception covers trimmed inventory only because the floor and the pace bound it. Both timelocks are the team Safe's, so this is an admin-exceeds-bounds path (High per THREAT-MODEL §4), not third-party theft; the wash trades cost only the LP fee. Fix (keeps the design: both settings stay adjustable): bound them in MarketController. For example refuse newFloor below initialCapFloor (or below a fixed share of it such as half), and cap tokensPerDay at a pace consistent with D-21 (e.g. a few times initialCapDecayPerDay, or a few percent of the opening inventory per day). The reward share (<= 30%) and the sinkAdmin power can stay as designed. Reproduced from audit_permissions' finding; the other specialists did not report it. **Reproduction** State: market open after graduation (300M $PONDPAD, 8,460 IMD). Calls: sinkAdmin controller.setRewardsRecipient(wallet); owner controller.setRewardShareBps(3000), controller.setCapFloor(0), controller.setCapDecay(type(uint128).max); one second later a trader does 60 round trips through PoolSwapTest (buy 2,000 IMD, sell all $PONDPAD back). Expected (ARCHITECTURE §5.6, D-21): the cap never falls below the documented floor region and the position cannot be removed by owner settings. Actual (test/scratch/CapFloorUnbounded.t.sol on this commit): inventoryCap = 428,533,929 wei (4e-10 $PONDPAD), tokensInPool = 0.099 $PONDPAD, 89,099,910 $PONDPAD paid to `wallet` as reward claims, 8,546 IMD moved from the position into retainedQuote/backstop. The test returns early (passes) as soon as either setter reverts, and otherwise asserts inventoryCap and tokensInPool stay >= 75M; it fails on this code with 'cap ratcheted far below the documented floor'. **Proof**: a Foundry test that fails on this code and passes once it is fixed. ```solidity // SPDX-License-Identifier: MIT pragma solidity 0.8.26; import {Test} from "forge-std/Test.sol"; import {ERC20} from "solady/tokens/ERC20.sol"; import {FixedPointMathLib} from "solady/utils/FixedPointMathLib.sol"; import {PoolManager} from "v4-core/PoolManager.sol"; import {IPoolManager} from "v4-core/interfaces/IPoolManager.sol"; import {Hooks} from "v4-core/libraries/Hooks.sol"; import {TickMath} from "v4-core/libraries/TickMath.sol"; import {PoolKey} from "v4-core/types/PoolKey.sol"; import {SwapParams} from "v4-core/types/PoolOperation.sol"; import {PoolSwapTest} from "v4-core/test/PoolSwapTest.sol"; import {PondPadToken} from "src/PondPadToken.sol"; import {PadBurner} from "src/PadBurner.sol"; import {FeeSplitter} from "src/FeeSplitter.sol"; import {PadMarketHook} from "src/PadMarketHook.sol"; import {MarketController} from "src/MarketController.sol"; contract MockIMD is ERC20 { function name() public pure override returns (string memory) { return "IMD"; } function symbol() public pure override returns (string memory) { return "IMD"; } function mint(address to, uint256 amount) external { _mint(to, amount); } } /// @dev Audit round 3, A2: `MarketController.setCapFloor` / `setCapDecay` have no bound.

Low: MarketController and FeeSplitter inherit Solady Ownable's transferOwnership / renounceOwnership / handover, so a delayed owner can hand every policy power to an undelayed address or freeze it (same cl `launchpad/contracts/src/MarketController.sol:32` ``` contract MarketController is Ownable, IPadMarketLauncher { ``` MarketController puts the policy setters (setCapFloor, setCapDecay, setRatchetBps, setRebalance, setKeeperReward, setMaxRefStep, setFloorDecay, setRewardShareBps), closeBackstop and fundInventory behind `owner`, which THREAT-MODEL §1 and D-57 name as the 48 h timelock ('Same as the Safe, delayed'). Nothing overrides Solady Ownable's public transferOwnership(address), renounceOwnership(), requestOwnershipHandover() / completeOwnershipHandover(address), so one 48 h-delayed proposal can move every policy power to the Safe or any EOA, which then acts with no delay and no public review window (closeBackstop closes the live buy wall at a moment of the new owner's choosing), or renounce and freeze the policy for good (no setter reachable again, including raising a cap floor set too high). D-79 made sinkAdmin immutable for exactly this reason (R1-A2-5) and RewardDripper / StakedPONDPAD override renounceOwnership, but the controller kept the default surface. FeeSplitter (launchpad/contracts/src/FeeSplitter.sol:11, 'contract FeeSplitter is Ownable {', owner = 7-day timelock) has the identical gap for setShares / setRecipients: D-78 removed PadConfig's splitter setter so fee routing changes only through the splitter's 7-day owner, yet that owner can delegate itself to an undelayed address. No pool asset or user fund moves through any of these setters (the hook bounds every setter; fundInventory pulls only from the caller), so this is a delay bypass, Low as R1-A2-5 was. Fix: override transferOwnership, renounceOwnership, requestOwnershipHandover and completeOwnershipHandover to revert on MarketController and FeeSplitter (or make the owner immutable as sinkAdmin is), with a test like test_market_sinkAdminIsFixed for `owner`; or document the power in THREAT-MODEL §1 if it is wanted. Merged from audit_math, audit_economics and audit_flow (one finding each, same mechanism). **Reproduction** On the Market.t.sol fixture after _graduate(): vm.prank(timelock); controller.transferOwnership(address(0xBEEF)); then vm.prank(0xBEEF); controller.setCapFloor(1); controller.closeBackstop(). Expected (THREAT-MODEL §1, D-57): the first call is impossible or the later calls revert Unauthorized. Actual: all succeed, controller.owner() == 0xBEEF and market.capFloor() == 1; vm.prank(0xBEEF); controller.renounceOwnership() then leaves owner() == address(0) and setCapFloor(2) reverts Unauthorized for everyone. Same for the splitter: splitter.transferOwnership(0xBEEF) by its owner, then setShares from 0xBEEF succeeds. Reproduced in test/scratch/JudgeRepro.t.sol (test_repro_controllerOwnershipTransferable, test_repro_splitterOwnershipTransferable; both pass on this commit, i.e. the transfers go through). ### 3. Low: afterSwap realises matured IMD claims with a `take` inside the swapper's unlock, so a v4-legal router that pays IMD before it swaps (sync, transfer, swap, settle) reverts whenever trimmed IMD is waiti `launchpad/contracts/src/PadMarketHook.sol:1167` ``` poolManager.take(Currency.wrap(quote), address(this), toQuote); ``` Generated by upstream/make_fork.py step 9 (`_currencyId(address(0))` -> `_currencyId(quote)`, `CurrencyLibrary.ADDRESS_ZERO` -> `Currency.wrap(quote)`), so the fix belongs in the script. afterSwap calls _maybeRedeemMaturedClaims, which in the first swap of a later Ethereum block runs _redeemClaims inside the swapper's own PoolManager unlock; its IMD leg burns the hook's ERC-6909 IMD claims and `take`s that IMD from the PoolManager to the hook. For an ERC-20, v4's settle() pays `reservesNow - reservesBefore` of the synced currency (PoolManager._settle), so a `take` of the synced currency between a router's sync and settle lowers reservesNow: a router following the legal order sync(IMD) -> transfer -> swap -> settle is short by toQuote. If toQuote exceeds what it paid, settle underflows (Panic 0x11); otherwise its IMD delta stays negative and the unlock reverts CurrencyNotSettled. Upstream CappedBurnHook took native ETH on this path, and a native settle{value} does not read synced reserves, so the ETH version never interfered with a router's settlement; the $PONDPAD-side takes (to burnSink / rewardsRecipient) already had this property upstream for sells and are 'POOL4 code we did not change' (THREAT-MODEL §3), which is why only the IMD leg is reported. Effect: buys through a pay-first router fail from the first swap of each Ethereum block after a trim until some other swap, settleClaims(), settleQuoteClaims() or rebalance() realises the claims (seconds to ~12 s after every sell above the cap, repeatedly). No funds are lost; swap-then-settle routers (Universal Router, V4Router, PoolSwapTest, PaymentSwapper, PadBuyer) are unaffected. It bends invariant 12 (behaves like CappedBurnHook except the listed changes). Fix in make_fork.py: don't move real IMD during a swap: have _maybeRedeemMaturedClaims call a token-only redeem and leave quoteClaims as claims (_payQuote already spends claims first, and _payKeeper / closeMarket / withdrawRetainedQuote call settleQuoteClaims themselves), or guard the IMD leg with `poolManager.getSyncedCurrency() != Currency.wrap(quote)` (TransientStateLibrary) so a pay-first router is left alone. From audit_flow; reproduced with my own router contract. **Reproduction** On the Market.t.sol fixture: _graduate(); trader sells 40,000,000 $PONDPAD through PoolSwapTest (trim: market.quoteClaims() > 100 IMD, lastClaimBlock = this block); _nextBlock(). A router R holding 100 IMD runs inside its own unlock: pm.sync(IMD); IMD.transfer(pm, 100e18); pm.swap(market.poolKey(), zeroForOne = true, amountSpecified = -100e18); pm.settle(); pm.take($PONDPAD, R, delta). Expected (as with the upstream ETH quote and any hook that does not move the synced currency): the buy succeeds and R receives $PONDPAD. Actual: the call reverts (settle's reservesNow - reservesBefore underflows because afterSwap took the matured IMD claims out of the PoolManager between R's sync and settle). Control: the same router call succeeds right after graduation with no pending claims, and succeeds again after a PoolSwapTest buy has realised the claims. Reproduced in test/scratch/JudgeRepro.t.sol (test_repro_syncFirstRouterRevertsWhileImdClaimsMature and test_repro_syncFirstRouterWorksWithoutPendingClaims, both pass on this commit). ### 4. Info: IMD or $PONDPAD transferred straight to PadMarketHook is stranded: not in any ledger, never swept, and left behind in the closed hook by migrate `launchpad/contracts/src/PadMarketHook.sol:643` ``` uint256 bal = SafeTransferLib.balanceOf(quote, address(this)); if (quoteToSend > bal) quoteToSend = bal; ``` Upstream's quote was native ETH and its receive() accepted only the PoolManager, so the hook's ETH balance always equalled its accounting. make_fork.py removes receive() and makes the quote an ERC-20, so anyone can transfer IMD (or $PONDPAD) directly to the hook. Nothing reads those balances into retainedQuote, untippedQuote or the fee ledger; _payQuote spends only what retainedQuote accounts for; closeMarket pays min(quoteOut + retainedQuote, bal) and takes $PONDPAD from the PoolManager, so direct sends are never redeployed, burned or carried into a new hook by migrate. Only tokens someone sent by mistake are affected, and the same sink behaviour is already accepted for PadHook (R2-A1-4, THREAT-MODEL §3), so Info: either document the PadMarketHook address as a sink too, or have closeMarket pay the whole quote balance (bal) instead of the accounted amount so stray IMD at least follows the market, and absorb surplus balance into retainedQuote (marked untipped) on migration. Merged from audit_math and audit_permissions (one finding each). **Reproduction** On the Market.t.sol fixture after _graduate(): imd.mint(this, 5e18); imd.transfer(address(market), 5e18); pondpad.transfer(address(market), 7e18); _swap(false, 10_000_000e18); _nextBlock(); market.rebalance(); approve and run controller.migrate(next). Expected (if the hook behaved like upstream, where no outside balance can exist): nothing left in the closed hook. Actual: imd.balanceOf(address(market)) == 5e18 and pondpad.balanceOf(address(market)) == 7e18 after the migration, with no function able to move them. Reproduced in test/scratch/JudgeRepro.t.sol::test_repro_directSendsToHookStranded (passes on this commit). ### 5. Info: fundInventory refunds the controller's whole IMD and $PONDPAD balance to the owner, so tokens sent to MarketController after launch go to the 48 h timelock instead of the splitter / burner `launchpad/contracts/src/MarketController.sol:242` ``` uint256 tokenLeft = token.balanceOf(address(this)); if (tokenLeft != 0) token.safeTransfer(msg.sender, tokenLeft); uint256 imdLeft = imd.balanceOf(address(this)); if (imdLeft != 0) imd.safeTransfer(msg.sender, imdLeft); ``` launch and migrate route every leftover in the controller to the fee splitter (IMD) or the burner ($PONDPAD) so that 'the controller keeps nothing and pays no one' (R1-A2-1, R2-A2-4, invariant 11). fundInventory instead returns balanceOf(address(this)) of both tokens to msg.sender (the owner), which includes anything a third party sent to the controller after launch. No pool asset is involved (the controller holds pool assets only transiently inside launch / migrate), so this is a consistency gap, not a loss, but it is the one path by which the controller pays a wallet. Fix: refund only the measured leftover of what fundInventory pulled (balance before pull minus balance after the hook call) and send any surplus to the splitter / burner as launch does, or document that post-launch donations to the controller belong to the owner. fundInventory also has no test (see the coverage note). Merged from audit_permissions and audit_economics. **Reproduction** On the Market.t.sol fixture after _graduate(): imd.mint(address(controller), 5e18); pondpad.transfer(address(controller), 7e18) (a third-party deposit). The owner funds a small position: vm.startPrank(timelock); approve both; controller.fundInventory(1e15, 100_000e18, 1e18). Expected (as in launch / migrate): the 5 IMD go to the fee splitter, the 7 $PONDPAD are burned, the owner gets back only its own unused maxima. Actual: the timelock ends with more than 5 IMD and more than 100,000 $PONDPAD (its own leftovers plus the deposit) and the controller holds 0 of both; the splitter and burner receive nothing. Reproduced in test/scratch/JudgeRepro.t.sol::test_repro_fundInventoryRefundsDonationsToOwner (passes on this commit). ### 6. Info: Untested edges in this area: MarketController.fundInventory is never called by any test, the Full-state graduation path is only tested for its revert, and every rebalance in the suite runs in a later `launchpad/contracts/test/Market.t.sol:251` ``` function test_market_controllerLimitsOwnerPowers() public { ``` The suite (138 local tests, all passing at this commit) does not exercise: (1) MarketController.fundInventory / PadMarketHook.fundInventory (no call site in test/*.sol), although it is the only way the 30M liquidity reserve enters the market and it carries the refund logic in the previous finding; (2) PadSale.graduate() after a completing buy wrapped in an outside PoolManager unlock, the only path that leaves the sale in Status.Full (_buy skips _graduate when poolManager.isUnlocked()); the suite's one graduate() call (test/PadSale.t.sol:251) only checks the NotFull revert; (3) rebalance() or settleClaims() in the same Ethereum block as the trimming swap: every market test calls _nextBlock() first, which matters on Robinhood where one block.number spans many transactions (D-65). In my scratch tests the fundInventory path adds liquidity and raises the cap as intended, so this is a coverage note (like R1-A1-10), not a defect. From audit_economics. **Reproduction** Observed state of the tree: `grep -rn fundInventory launchpad/contracts/test/*.sol` returns no call site; `grep -rn 'graduate()' test/*.sol` finds only PadSale.t.sol:251 behind vm.expectRevert(NotFull); in Market.t.sol every rebalance() is preceded by _nextBlock(). Expected: a test per edge (fundInventory adds liquidity, raises inventoryCap and refunds the leftovers; a Full sale graduates through graduate(); a same-block rebalance deploys from claims minted by an earlier settled swap). --- Judge's submission `825d82831bdbd5fddafca6b5a097fd6e75460a0c8ceeaaf883e3788d67edface`, accepted on the IdentityMD network. Acceptance means the report met the job's checks; it is not a guarantee that the code has no other defects.
