# Audit report > PondPad v1 security audit, round 6, 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. > Changed since round 3 (D-80): MarketController refuses a cap floor below the deploy floor and a decay above 5x the deploy pace; fundInventory refunds only what it pulled (other balances to the splitter / burner); make_fork.py: refTick steps maxRefStep per block elapsed since the last swap, and matured claims are not realised inside a swap while IMD or $PONDPAD is synced; owners are fixed (FixedOwnable); FeeSplitter.distributeToken only $PONDPAD. > Changed since round 4 (D-83): MarketController.setCapFloor also refuses a floor above the hook's current inventoryCap, so a floor change can't lift the cap and stop the trims (R4-A2-1); collectFees also calls PadBurner.burn() (R4-A2-2); make_fork.py adds referenceTick() (the reference as the next swap's _observeTick will set it: refTick caught up toward the last swapped block's close, refTick itself once this block had a swap), which _observeTick now uses and PadBuyer reads (R4-A3-3). Since the check before round 5 (D-84): make_fork.py lowers the default maxRefStep from POOL4's 200 to 100 ticks per Ethereum block (listed change 9, audit R2-A3-6; setMaxRefStep's 1..2000 range and its 48 h owner unchanged), so the reference moves at most ~1% per block; testFuzz_market_capInvariantAtBothFeeLevels no longer runs its trader out of $PONDPAD (P5-1, test only; test_market_capFuzzReplaysTheFlakySeed replays the failing input). > Changed since round 5 (D-86): MarketController.fundInventory reverts (PriceOutOfRange) unless the market's tick is within MAX_FUND_DEVIATION_TICKS = 100 (a constant) of hook.referenceTick(), so whoever executes the queued 48 h add can't run it inside a pump made in the same block (R5-A2-1); migrate passes old.referenceTick(), not the stored refTick, to inheritGuards (R5-A2-2 / R5-A3-1, the migration half of R4-A3-3); setCapFloor's NatSpec: a floor proposal leaves a margin of the decay allowance banked by execution, and the cap is held with setCapDecay(0) (R5-A2-3, documented). make_fork.py and PadMarketHook are unchanged. Since the check before round 6 (D-87, FINDINGS P6-1): THREAT-MODEL invariant 11 and section 3 say the fundInventory band holds within one Ethereum block (a pump held across blocks moves referenceTick() by maxRefStep per block, and the add can then run at that price) and give the owner rule that bounds the rest (each maximum's slack below 2 x fee x pool liquidity / added liquidity, 1.2x today; the Safe cancels a queued add when the price leaves that band); no code change. > 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. Low: A stranger's $PONDPAD sent to MarketController before migrate is folded into the new market position (cap raised, backstop IMD consumed) instead of being burned `launchpad/contracts/src/MarketController.sol:349` ``` uint128 liquidity = fullRangeLiquidity(sqrtPriceX96, imdBal, tokenBal, nh.tickSpacing()); ``` `migrate` sizes the new full-range position from the controller's whole IMD and $PONDPAD balances after `old.closeMarket` (`imdBal`, `tokenBal`, lines 346-350) and burns only what does not fit. The IMD balance includes the old market's retained and backstop IMD, so the token side is binding and every $PONDPAD on the controller goes into the position with a matching slice of that IMD. Anyone can transfer $PONDPAD to the controller (nothing sweeps it between launch and migrate; `approveMigration` announces a migration 7 days ahead), so an unprivileged sender enlarges the position, lifts `inventoryCap` to the larger `tokensDeposited` (above `oldCap`, which `inheritGuards` then keeps) and converts part of the buy wall below the price into full-range liquidity at the current price. This contradicts `fundInventory`'s NatSpec (lines 260-261: tokens already on the controller are burned 'as in launch and migrate'), `migrate`'s own NatSpec ('the controller keeps nothing') and ARCHITECTURE 5.4.1 / THREAT-MODEL invariant 11, where only the 48 h owner raises the cap (through `fundInventory`). Nothing leaves the protocol and the sender pays the donation, so this is griefing of the burn programme (trims delayed by donation / 500k per day of decay) within a listed power's effect: Low. Fix: in `migrate`, before `old.closeMarket`, send whatever the controller already holds to the fee splitter (IMD) and to the burner ($PONDPAD, then `burn()`), as `launch` and `fundInventory` do, so the position and the backstop seed are sized only from what the close returned. Merged: reported by audit_economics only; verified by running its proof and an independent probe. **Reproduction** MarketBase setup (test/Market.t.sol): PoolManager, $PONDPAD mined above IMD, sale graduated at 8,460 IMD / 300M $PONDPAD, cap floor 150M, decay 500k/day. Trader sells 40,000,000e18 $PONDPAD (trim); next block `market.rebalance()` deploys the retained IMD (backstop 856.90 IMD); the 7-day timelock approves a fresh hook; a stranger transfers 1,000,000e18 $PONDPAD to the controller; the Safe (`migrator`) calls `migrate(newHook)`. Expected (NatSpec, invariant 11): new `inventoryCap` = old cap 299,999,699.99 $PONDPAD, `tokensInPool` unchanged, `retainedQuote` ~856.9 IMD seeded, the 1M donation burned. Actual: `next.inventoryCap()` = 300,999,399.00 $PONDPAD, `next.tokensInPool()` = 300,999,399.00, `next.retainedQuote()` = 834.80 IMD (22.1 IMD of backstop moved into the position), the donation not burned (only the trim's 32.98M claims and ~300 $PONDPAD of rounding dust are). Without the donation the same run gives cap 299,999,699.99 and retained 856.90. The attached proof fails on this commit with 'the cap is the old market's cap, not raised by a stranger: 300999399000299999999999804 != 299999699999999999999999885'. **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;

Info: Seeded or owner-returned backstop IMD still pays the keeper fill tip once the band it was deployed into fills; invariant 11 and the untippedQuote NatSpec read as if it never earns a tip `launchpad/contracts/src/PadMarketHook.sol:734` ``` uint256 tip = _keeperRewardDue(idleReady ? tippable : 0, converted); ``` The R2-A2-1 fix (`untippedQuote`) removes the tip only on the idle-deployment leg: `tippable` excludes IMD that came back from an owner `closeBackstop` or a migration `seedRetainedQuote`. The fill leg is unchanged: `_keeperRewardDue` takes `converted` (IMD principal of the live band that a dump turned into tokens) as work value, and once the untipped IMD has been deployed as the band `untippedQuote` is clamped to 0 (line 736), so when that band fills the next `rebalance()` pays min(`keeperReward`, `currentFee()` x converted) out of retained IMD that originated from the seed or the owner close. THREAT-MODEL invariant 11 ('IMD returned by an owner closeBackstop or seeded by a migration earns no keeper tip'), ARCHITECTURE 5.4.1 (`closeBackstop` row) and the `untippedQuote` NatSpec state no such exception. The actual bound is POOL4's: the tip is at most the pool fee on the converted IMD, and the dump that converted it paid at least that much fee to the protocol (below: ~1.46M $PONDPAD, ~41 IMD at the pool price, in fees for a 1 IMD tip), so no value can be extracted and the R2-A2-1 loop (closeBackstop + rebalance with no trade) stays closed. Documentation only: say in invariant 11 / the NatSpec that the untipped IMD earns no idle-deployment tip but a later fill of the band it funds pays the ordinary fee-bounded fill tip; or, if the stricter reading is wanted, carry an untipped share into `backstopQuotePrincipal` and subtract it from `converted` in `_keeperRewardDue` (an owner design choice, since it also stops tipping a legitimate fill). Merged: reported by audit_flow; verified with a scratch probe (both the migration-seed and the owner-closeBackstop path). **Reproduction** MarketBase setup, day 0 (fee 3%): `_graduate()`; trader sells 40,000,000e18 $PONDPAD (trim); next block `market.rebalance()`; the 7-day timelock approves a fresh hook and the Safe migrates. New hook: `retainedQuote` = `untippedQuote` = 856.906 IMD. Keeper calls `next.rebalance()`: keeper receives 0 IMD (expected, R2-A2-1), band principal 856.906 IMD, `untippedQuote` now 0. Trader sells 55,000,000e18 into `next.poolKey()`: `backstopConvertedQuote()` = 116.58 IMD, `backstopIsFilled()` true, the dump paid 1,461,241 $PONDPAD into `feeTokenClaims`. Next block keeper calls `next.rebalance()`: keeper receives 1.000 IMD (`keeperReward`; fee bound 3% x 116.58 = 3.50 IMD), paid from retained IMD that was the seed. Expected per the wording of invariant 11: 0. Same result with an owner `controller.closeBackstop()` instead of a migration seed (keeper receives 1.000 IMD after the fill). ### 3. Info: Untested A2 guards: a second pool key on the market hook, fundInventory maxima, the rebalance kill switch, the controller's pass-through setter bounds, a cleared migration approval, strangers on the f `launchpad/contracts/test/Market.t.sol:345` ``` function test_market_outsidersCannotInitializeOrAddLiquidity() public { ``` The local suite (210 tests, all passing at this commit) exercises the market's main paths, but these guards have no test, so a regression in any of them would pass CI. Each was checked with a scratch test at this commit and holds today: (1) `PoolManager.initialize` with a second key on the same hook (fee 3000 / tickSpacing 60, or the real key with tickSpacing 60) reverts in `beforeInitialize` via `_requirePoolManagerAndPool` (`InvalidPool`); the existing test only re-initializes the hook's own key. (2) `MarketController.fundInventory(liquidity, maximumTokenAmount, maximumImdAmount)` with a maximum below what the liquidity needs reverts (`TokenAmountExceeded` / `IncorrectQuoteAmount`) and pulls nothing. (3) `setRebalance(false, 41e18)` makes `rebalance()` revert `RebalanceDisabled` and `pendingRebalance()` false with retained IMD above the threshold. (4) Through the controller: `setMaxRefStep(0)` and `(2001)`, `setFloorDecay(0)`, `setRatchetBps(10001)`, `setKeeperReward(41e18)` (>= threshold), `setRebalance(true, 0)` revert `InvalidConfiguration`; `setMaxRefStep(2000)` and `setRatchetBps(0)` pass. (5) `approveMigration(addr)` then `approveMigration(address(0))`: `migrate(addr)` and `migrate(address(0))` revert `InvalidSetup`. (6) Strangers calling the fork's owner-only functions directly on the hook (`seedRetainedQuote`, `inheritGuards`, `inheritFeeSchedule`, `setCapFloor`, `closeBackstop`, `closeMarket`, `withdrawRetainedQuote`, `withdrawFees`) revert `Unauthorized`; `redeemClaimsSelf` / `closeBackstopSelf` revert `NotSelf`; `unlockCallback` reverts `InvalidPoolManagerCaller`. Adding one unit test per guard, as the R3-A2-6 / R4-A2-3 rows did, closes the gap; no contract change. Merged: reported by audit_flow; verified by grepping the local tests for each guard name (none present) and a scratch test of every item. **Reproduction** Grep `test/Market.t.sol`, `PadSale.t.sol`, `Base.t.sol`, `Staking.t.sol`, `Distribution.t.sol`, `Governance.t.sol`, `PondPad.t.sol`, `Invariant.t.sol`, `Funds.t.sol` for `InvalidPool`, `TokenAmountExceeded`, `IncorrectQuoteAmount`, `RebalanceDisabled`, `setMaxRefStep(0`, `setMaxRefStep(2001`, `setFloorDecay(0`, `setRatchetBps(10001`, `setKeeperReward(41e18`, `approveMigration(address(0))`, `NotSelf`, `InvalidPoolManagerCaller`, `seedRetainedQuote`, `inheritGuards`, `tickSpacing: 60`: no match in any local test. Scratch test at this commit (MarketBase after `_graduate()`): PoolKey{IMD, $PONDPAD, 3000, 60, market} and the real key with tickSpacing 60 both revert on `pm.initialize`; after a 40M sell and `setRebalance(false, 41e18)`, `rebalance()` reverts `RebalanceDisabled` and `pendingRebalance()` is false; the six setter calls above revert `InvalidConfiguration` and the two valid ones pass; after `approveMigration(address(0))` both `migrate` calls revert `InvalidSetup`; every stranger call reverts with the error named; `fundInventory` with a 1e18 token or IMD maximum reverts. Expected and actual agree in every case: coverage only, no defect. ### 4. Info: LiquidityReserve.release() has no local (non-fork) test; only DeployFork.t.sol exercises the MarketNotOpen gate and the release to the 48 h timelock `launchpad/contracts/src/LiquidityReserve.sol:33` ``` function release() external returns (uint256 amount) { ``` THREAT-MODEL invariant 10 says the 30M reserve can't move until the market is open (D-79, R1-A2-4). The contract enforces it (`release` reverts `MarketNotOpen` while `MarketController.openedAt() == 0` and afterwards pays only the fixed beneficiary), but the only tests are in `test/DeployFork.t.sol`, which needs `FORK_RPC`. `forge test --no-match-contract Fork`, the command auditors and CI run, never deploys or calls `LiquidityReserve` (no reference in `Base.t.sol`, `Market.t.sol`, `PadSale.t.sol`, `Distribution.t.sol` or any other local test). A regression that let `release()` pay before launch, or pay another address, would not fail the local suite. Coverage only; no code defect. Fix: a MarketBase test asserting `release()` reverts `MarketNotOpen` before `_graduate()`, pays exactly 30,000,000e18 to the beneficiary after it, and returns 0 on a second call. Merged: reported by audit_math; verified by grep and a local scratch test of that exact behaviour (passes). **Reproduction** Fresh checkout: `grep -ln LiquidityReserve launchpad/contracts/test/*.sol` prints only `test/DeployFork.t.sol`; `cd launchpad/contracts && forge test --no-match-contract Fork` runs 210 tests, none constructs or calls `LiquidityReserve`. Scratch test (MarketBase): `new LiquidityReserve(pondpad, controller, timelock)` holding 30,000,000e18; `release()` before `_graduate()` reverts `MarketNotOpen`; after `_graduate()` it returns 30,000,000e18 and the timelock holds exactly that; a second `release()` returns 0. Expected (R3-A2-6 / R4-A2-3 practice): that test in the local suite. Actual: only the fork rehearsal checks it. --- Judge's submission `353ee82d6799a5c4555e09d0e9a7447900a980bcd7f47d35a73f02af2628aabd`, 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.
