# Audit report > PondPad v1 security audit, round 2, area A4: Governance, takeovers and deployment. 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).

Bar: approved signer, panel >= 51, agreed >= 2/3 and >= quorum, validity window. CTOModule moves a coin's creator-fee recipient after an oracle "yes" (or the team council, until retired), with notice, contest, cooldown and guards; the new recipient is a multisig or the coin itself (fees to holders). VersionRegistry activates launchpad versions by audit attestation over an onchain code hash. SocialRegistry links X handles by vouchers. Deploy.s.sol deploys and wires everything in one run, hands every power to two OpenZeppelin TimelockControllers (48 h, 7 days; Safe proposes, anyone executes) and must leave the deployer with nothing. > Changed since round 1 (D-78): CTOModule stores the proposer handle and contestedAt (confirmation issued after the contest), 90-day council cooldown per coin after a cancel, attested proposals replace pending council ones, retired council proposals can't execute, EIP-7702 wallets refused; VersionRegistry activation moves currentVersion only forward; exact two thirds accepted; PadConfig fee splitter and growth fund immutable; CreatorVault holder stream and hook flush before a takeover switch; SwarmBudget requests of holder-routed coins cancellable by anyone; Deploy reuses an existing contract at a CREATE2 address. > Look hardest at: > - Attestation binding: can one attestation be reused for another coin, recipient, proposer, version, window or consumer? JSON escaping of question text built from user input (names, symbols, handles, links): can a crafted string make two different questions hash the same, or inject fields? > - CTO state machine: propose / contest / confirm / execute / cancel ordering, windows and their edges, cooldown, fallback retirement being truly one-way, interaction with CreatorVault recipient changes and SwarmBudget.sweepToHolders. > - VersionRegistry code hash and rollback; SocialRegistry nonces, deadlines, flags. > - PadConfig bounds and who may call each setter (owner vs. guardian). > - Deploy.s.sol: compare every owner, role, address and amount with DECISIONS.md D-57 and THREAT-MODEL.md section 1; anything left with the deployer; CREATE2 salt mining and hook flags; ordering bugs (a contract initialized with a wrong or zero address). > > 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. Medium: CTOModule.execute run from inside an outside PoolManager unlock skips the pre-switch hook flush: creator fees pending in PadHook go to the new recipient (R1-A4-8 fix bypassed) `launchpad/contracts/src/CreatorVault.sol:174` ``` if (hook.code.length != 0) IFeeFlusher(hook).flush(coin); // credits this vault before the switch ``` Reported by all four specialists; merged. The R1-A4-8 fix makes CreatorVault.ctoSetRecipient call PadHook.flush(coin) so creator fees still pending in the hook (from swaps through outside routers since the last flush) are credited to the vault and paid to the old recipient before the switch. But PadHook.flush (src/PadHook.sol:341) returns silently while the PoolManager is unlocked, CTOModule.execute is permissionless and has no unlock guard, and the vault's nonReentrant does not engage because the vault is not on the call stack when an outside contract's unlockCallback calls the module. So whoever executes the takeover from inside their own poolManager.unlock(...) callback makes the flush a no-op: the old recipient is paid only balanceOf[coin], the recipient switches, and the next flush by anyone credits the pending creator share to the NEW recipient. This contradicts CTOModule's header ('Fees accrued before execution go to the old recipient'), CTO-RULES ('Fees earned before the takeover are paid to the old receiver') and the fix recorded in FINDINGS.md for R1-A4-8; its regression test test_cto_hookPendingFeesGoToOldRecipient only executes from a plain context. The incoming recipient (the proposer's multisig, or any holder of a coin being routed to holders) picks the execution moment inside the 3-day window, e.g. after a burst of outside-router volume, and nobody can flush inside the attacker's unlock. Loss is bounded by the creator share of outside-router volume since the last flush (keeper cadence: HANDOFF section 6), so Medium (bounded loss, attacker pays only gas). Invariant 17 context checked. Fix: in ctoSetRecipient revert when IHolderCoin(coin).poolManager().isUnlocked() (the vault already reads the coin's pool manager in _releaseToHolders; BondingCurve._checkLocked is the same pattern), or have CTOModule.execute refuse to run while the PoolManager is unlocked. The attached proof passes with the first fix (verified by patching the vault locally and restoring it). **Reproduction** Graduated coin with no coin tax, creator = fee recipient, vault.claim(coin) done so balanceOf[coin] == 0. Council (or an attested proposer) proposes a takeover to a contract newOwner; the notice passes. An outside router (PoolSwapTest) swaps 100 IMD into the pool: hook.pending(coin).creator == 0.5e18. A contract calls poolManager.unlock(...) and in its unlockCallback calls cto.execute(coin). Expected (R1-A4-8): creator receives 0.5 IMD and vault.balanceOf(coin) == 0 after the switch. Actual: execute succeeds inside the unlock, flush returned early, creator receives 0; after hook.flush(coin) the 0.5 IMD sits in vault.balanceOf(coin) for newOwner. test/scratch/CtoExecuteInsideUnlock.t.sol fails on this code with 'old recipient paid the fees pending at execution: 0 != 500000000000000000' and passes once ctoSetRecipient reverts while the coin's PoolManager is unlocked. ### 2. Medium: Holder stream funding inside an outside PoolManager unlock skips the due release but still resets lastReleaseAt: a 1 wei fundHolders wipes up to a day of accrued holder dividends, repeatable before ev `launchpad/contracts/src/CreatorVault.sol:134` ``` _releaseToHolders(coin); HolderStream storage st = holderStreamOf[coin]; uint256 remaining = st.remaining + amount; st.remaining = uint128(remaining); st.ratePerSecond = uint128((remaining + HOLDER_STREAM_PERIOD - 1) / HOLDER_STREAM_PERIOD); st.lastReleaseAt = uint64(block.timestamp); ``` Reported by three specialists (one Medium, two Low); merged. CreatorVault._fundHolders first calls _releaseToHolders and then unconditionally sets st.lastReleaseAt = block.timestamp and recomputes the rate. _releaseToHolders deliberately releases nothing while an outside caller holds the PoolManager unlock (line 148, the D-78 guard against flash positions) and leaves lastReleaseAt untouched so the accrued time survives until the next release. The reset in _fundHolders throws that time away. fundHolders(coin, amount) is permissionless for any registered coin and only needs amount > 0, so a stranger calling vault.fundHolders(coin, 1) from inside their own unlockCallback (the vault's nonReentrant is not engaged: the vault is not on the stack) erases up to MAX_RELEASE_GAP (one day) of accrued stream time per call for 1 wei of IMD plus gas. The same reset is reachable through claim(coin) when the recipient is the coin, SwarmBudget.sweepToHolders(coin) and ctoSetRecipient when the old recipient is the coin, all called inside an outside unlock. Repeating the call before each keeper release (HANDOFF section 6: releaseToHolders daily) makes every honest release pay rate x (seconds since the attacker's last reset), so the creator fees and swept swarm budget routed to a holder-routed coin (D-52, D-78) are never released while the attacker keeps paying gas. The IMD is not lost (remaining is intact), which keeps this at Medium (griefing that costs the attacker far less than the victims; weakens invariant 6's '~7 days' promise). It is a regression introduced by the R1-A4-1 fix; its tests (test_cto_routeFeesToHolders, test_cto_holderLumpCantBeCapturedInOneBlock) cover only the happy path and one-block capture. Fix: refuse _fundHolders (and so fundHolders / claim / sweepToHolders / ctoSetRecipient) while IHolderCoin(coin).poolManager().isUnlocked(), mirroring BondingCurve._checkLocked; or only move lastReleaseAt when the release actually ran or the stream was empty. The attached proof (the specialists' test, which swallows a revert from the vault) passes with the first fix; verified locally by patching the vault and restoring it. See also the Low finding on the same function about dust top-ups re-spreading the schedule outside any unlock. **Reproduction** Coin FROG launched; alice buys 100 IMD so holders exist; creator calls vault.setRecipient(coin, coin); vault.claim(coin) funds the holder stream with the accrued creator fees (0.5 IMD; rate = ceil(0.5e18 / 7 days)). Warp +1 day: vault.releasableToHolders(coin) == 71428571428608000. A contract calls poolManager.unlock(...) and in unlockCallback calls vault.fundHolders(coin, 1). Expected: the day's share is paid first (or the call is refused), so vault.releaseToHolders(coin) right afterwards returns about 0.0714 IMD. Actual: fundHolders succeeds, _releaseToHolders returned 0 because isUnlocked() was true, lastReleaseAt is now, and releaseToHolders(coin) returns 0. test/scratch/HolderStreamStall.t.sol fails on this code with 'the accrued day's share was erased by the stranger's call: 0 !~= 71428571428608000'. **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 {PoolManager} from "v4-core/PoolManager.sol"; import {IPoolManager} from "v4-core/interfaces/IPoolManager.sol"; import {IUnlockCallback} from "v4-core/interfaces/callback/IUnlockCallback.sol"; import {Hooks} from "v4-core/libraries/Hooks.sol"; import {PadConfig} from "src/PadConfig.sol"; import {BondingCurve} from "src/BondingCurve.sol"; import {PadHook} from "src/PadHook.sol"; import {PadFactory, LaunchParams} from "src/PadFactory.sol"; import {PadRouter} from "src/PadRouter.sol"; import {CreatorVault} from "src/CreatorVault.sol"; import {SwarmBudget} from "src/SwarmBudget.sol"; import {FeeSplitter} from "src/FeeSplitter.sol"; import {IntegratorVault} from "src/IntegratorVault.sol"; import {CoinFees} from "src/FeeLib.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 Any contract: unlocks the PoolManager and, inside its own unlock, adds 1 wei to a coin's holder stream. /// Reverts from the vault are swallowed so the test also runs against a fix that refuses the call. contract StreamStaller is IUnlockCallback { IPoolManager internal immutable pm; CreatorVault internal immutable vault; address internal immutable imd; constructor(IPoolManager pm_, CreatorVault vault_, address imd_) { pm = pm_; vault = vault_; imd = imd_; ERC20(imd_).approve(address(vault_), type(uint256).max); } function stall(address coin) external { pm.unlock(abi.encode(coin)); } function unlockCallback(bytes calldata data) external override returns (bytes memory) { require(msg.sender == address(pm)); address coin = abi.decode(data, (address)); try vault.fundHolders(coin, 1) {} catch {} return ""; } } /// @notice CreatorVault._fundHolders stamps `lastReleaseAt = now` even when `_releaseToHolders` released nothing /// because an outside caller holds the PoolManager unlock.

Low: Anyone re-spreads a coin's holder stream with 1 wei top-ups: fundHolders resets the rate and restarts the 7-day period, so a lump that should pay out in ~7 days keeps ~34% unpaid after 7 daily top-ups `launchpad/contracts/src/CreatorVault.sol:138` ``` st.ratePerSecond = uint128((remaining + HOLDER_STREAM_PERIOD - 1) / HOLDER_STREAM_PERIOD); ``` Reported by two specialists; merged. Outside any unlock, fundHolders(coin, amount) by anyone (amount >= 1 wei) first pays what is due and then recomputes ratePerSecond = ceil((remaining + amount) / 7 days) from the whole remainder and restarts the clock, i.e. the remainder is rescheduled over 7 more days. A 1 wei top-up a day turns the linear 7-day stream (D-78, R1-A4-1: 'released over about 7 days') into a geometric one: (6/7)^n of the lump is still unreleased after n daily top-ups (34% after 7 days, 12% after 14, 4% after 21) and the stream never formally ends. Nothing is lost and the griefer gains nothing (gas plus 1 wei a day), so Low: delay of a holder-routed coin's dividends, e.g. by an ousted creator or a competitor. Distinct mechanism and fix from the Medium clock-reset finding on the same function. Fix: a top-up may only keep or raise the rate (rate = max(oldRate, ceil(remaining / 7 days))), or require a minimum top-up / restrict fundHolders to SwarmBudget and the vault itself. The attached test passes with the max-rate fix (only the griefer's own 7 wei remain). **Reproduction** Coin whose recipient is the coin itself (fees to holders); vault.fundHolders(coin, 700e18) at t0 (rate 700 IMD / 7 days). Each day d = 1..7 at t0 + d days: vault.releaseToHolders(coin), then a stranger calls vault.fundHolders(coin, 1). Expected (D-78 '~7 days'): holderStreamOf(coin).remaining == 0 (or only the 7 wei of dust) after day 7. Actual: day 1 releases 100 IMD, the remaining 600 is re-spread at 85.7/day; day 2 releases 85.7; ...; 237.94 IMD (34%) is still unreleased after day 7. test/scratch/HolderStreamStretch.t.sol fails on this code with 'lump paid out within 7 days: 237941673962379424007 > 7'. **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 {CreatorVault} from "src/CreatorVault.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); } } contract MockPM { /// @dev TransientStateLibrary.isUnlocked reads the unlock flag through `exttload`; never unlocked here. function exttload(bytes32) external pure returns (bytes32) { return bytes32(0); } } /// @dev Stands in for a PadToken whose fees go to holders: receives IMD, `distribute()` is a no-op here. contract MockCoin { MockPM public pm = new MockPM(); function poolManager() external view returns (MockPM) { return pm; } function distribute() external {} } /// @dev A stranger adding 1 wei to a coin's holder stream.

With it: ~(6/7)^7 of the lump, about 34%. // Only the griefer's own 7 wei may still be in the stream. assertLe(remaining, 7, "lump paid out within 7 days"); } } ``` ### 4. Low: Consumers never pin the attestation's evidence chain or block window: an answer whose evidence frame is chain 1 (or any window) verifies for a Robinhood takeover or version activation `launchpad/contracts/src/AttestationVerifier.sol:88` ``` if (att.questionHash != questionHash(question, att.chainId, att.fromBlock, att.toBlock)) revert WrongQuestion(); ``` Reported by three specialists (Info/Low); merged. The oracle's canonical question JSON carries chainId and window {fromBlock, toBlock}, which tell the oracle and its panel which chain's state and block range the question is about. verifyBool rebuilds the hash from the attestation's own three values (D-49: 'rebuild the hash from the attestation's window') and neither it nor CTOModule.propose / confirm nor VersionRegistry.activate require att.chainId == block.chainid or a sane, recent window. The requester therefore chooses the evidence frame the oracle is told to use: for a takeover, a window ending at a block when the creator had been idle for 30 days (CTO-RULES R2 'Abandoned') before they resumed; for a version activation, a window from before a later redeploy. The question text itself names chain 4663 and the rules tell the panel to prefer live Robinhood data, so a careful panel is not fooled and the contract-side invariant 16 (exact rebuilt question hash, signer, panel, agreement, validity, once) holds as written; whether the panel honours the window over the text is an oracle-side property the repository does not document. Low: a missing binding with no demonstrated loss. Cheap hardening: in verifyBool require att.chainId == block.chainid (the live-attestation test uses chainId 1 only through the pure questionHashTyped and is unaffected), require att.fromBlock <= att.toBlock, and let consumers bound the window (e.g. toBlock not older than the notice period; block.number is the Ethereum block, D-65), or at least emit the window in Proposed / Activated so reviewers see it. **Reproduction** Approved signer; bob linked to X handle frogdao; coin 30 days old. Build an OracleAttestation with chainId = 1, fromBlock = 0, toBlock = 0, questionHash = verifier.questionHash(cto.question(coin, newRecipient, 'frogdao'), 1, 0, 0), answer true, panel 60 / quorum 40 / agreed 50, valid window, signed by the signer; bob calls cto.propose(coin, newRecipient, att, sig). Expected under a strict reading of 'one exact question': refused because the evidence chain is not 4663 and the window is empty. Actual: accepted, pendingOf(coin).newRecipient == newRecipient. test/scratch/CtoMisc.t.sol test_lead_chainIdAndWindowNotBound passes on this code (it asserts the acceptance). Same shape for VersionRegistry.activate. ### 5. Low: CTOModule.confirm binds the second answer to the contest only through issuedAt: the confirmation question is fully known at propose time, so it can be ordered before any contest and still counts once `launchpad/contracts/src/CTOModule.sol:269` ``` if (att.issuedAt < t.contestedAt) revert AnswerBeforeContest(); ``` Reported by one specialist; reproduced. CTO-RULES ('Contested takeovers') and invariant 17 require the >= 75 panel to answer a question asked after the contest, so the creator's answer and new evidence are considered. The R1-A4-3 fix checks att.issuedAt >= t.contestedAt, but issuedAt is when the oracle issued the answer, not when the question was asked, and confirmQuestion(coin, newRecipient, proposerX) contains nothing that only exists after a contest: its text is computable the moment the takeover is proposed (or earlier). A proposer can order the confirmation question at propose time so the panel deliberates with no contest and no creator evidence onchain; if the creator contests during the 3-day notice, any answer issued afterwards is accepted. The panel would have to answer true to a question whose premise ('contested by the current fee recipient') did not hold when asked, which rules item 1 forbids, so this needs panel error and is Low; the contract can close it cheaply. Fix: put contest-specific data in the question text so it cannot be formed earlier, e.g. '... contested by the current fee recipient at unix time ...', and have confirmQuestion revert while the proposal is not contested. **Reproduction** Bob (X frogdao) proposes at time P with a valid attestation. At P (before any contest) he reads cto.confirmQuestion(coin, to, 'frogdao') and orders that oracle question. Creator contests at P + 5 h (contestedAt = P + 5 h). The oracle issues 'true' from an 80-member panel at P + 6 h for the pre-asked text. cto.confirm(coin, att, sig) at P + 6 h: expected rejected (question asked before the contest); actual accepted, pendingOf(coin).confirmed == true. test/scratch/CtoMisc.t.sol test_lead_confirmQuestionKnownBeforeContest passes on this code (it asserts the text is identical before and after the contest and that the confirmation lands). ### 6. Low: CTOModule checks that the recipient is a contract only at propose: execute never re-checks, so a recipient created and self-destructed in the propose transaction (EIP-6780) or one whose code changed e `launchpad/contracts/src/CTOModule.sol:218` ``` if (newRecipient == current || newRecipient.code.length == 0 || _isDelegatedAccount(newRecipient)) { ``` Reported by one specialist; reproduced as a missing check. _propose requires newRecipient.code.length != 0 and not an EIP-7702 designator; execute (lines 294-306) re-checks nothing. Under Cancun, SELFDESTRUCT removes code only when it runs in the transaction that created the contract, so a proposer can, in one transaction, CREATE2-deploy a contract, name it in propose / proposeByCouncil and self-destruct it; after execution the fee recipient is an address with no code that can be redeployed at the same CREATE2 address with different runtime code (metamorphic init code). In practice the attested path is not exploitable this way without panel error: CTO-RULES R3 requires the panel to verify a Safe with >= 3 owners at the named address before answering, and a contract that existed when the panel looked cannot be self-destructed later (not the creation transaction); the council could name any key-controlled forwarder anyway. So this is a hardening of invariant 17's 'contract recipient' guard with no realistic path today (Low). Fix: in execute re-check newRecipient.code.length != 0 and !_isDelegatedAccount(newRecipient), and optionally store newRecipient.codehash at propose and require it unchanged at execute. **Reproduction** Council proposes a takeover to a contract C (any code) at P. The code at C is then removed (modelled with vm.etch(C, '') in Foundry, since the EIP-6780 same-transaction self-destruct cannot be observed inside one test transaction): C.code.length == 0. At P + 7 days anyone calls cto.execute(coin). Expected: a recipient that is no longer a contract cannot take the fees. Actual: no recipient check runs, creatorVault.recipientOf(coin) == C. test/scratch/CtoMisc.t.sol test_lead_recipientCodeNotRecheckedAtExecute passes on this code (it asserts the code-less recipient took the fees). ### 7. Low: CTOModule constructor accepts a rules link of up to 2,000 characters although every takeover question must fit in 2,000: an over-long CTO_RULES deploys fine but makes propose (and/or confirm) revert f `launchpad/contracts/src/CTOModule.sol:129` ``` verifier.checkQuestionText(rulesURI_); ``` Reported by one specialist; reproduced. The constructor validates rulesURI_ only with verifier.checkQuestionText (non-empty, printable ASCII, <= 2,000 bytes) and the ipfs:// prefix. question() wraps the link in about 315 fixed characters plus the handle (<= 15) and two hex addresses (42 each), confirmQuestion() in about 395, and verifyBool applies the same 2,000-byte limit to the whole text. A rules link longer than about 1,685 bytes is accepted at deploy but makes every propose revert BadQuestionText; one between about 1,605 and 1,685 lets propose work but makes every contested takeover impossible to confirm. rulesURI has no setter (D-51: fixed forever) and CreatorVault.initialize binds ctoModule once, so the only recovery is redeploying the vault, curve, hook and everything wired to them. Real IPFS links are 60-70 characters and Deploy.s.sol takes CTO_RULES from the environment, so this is a deployment foot-gun rather than an attack (Low). Fix: bound rulesURI_ in the constructor (e.g. <= 256 bytes) or build the longest possible question there and run checkQuestionText on it. **Reproduction** Deploy CTOModule with rulesURI_ = 'ipfs://' followed by 1,700 'a' (1,707 bytes): the constructor succeeds. cto.question(coin, newRecipient, 'frogdao') is longer than 2,000 bytes and verifier.checkQuestionText(question) reverts BadQuestionText; a propose(coin, newRecipient, att, sig) with a properly signed attestation from the approved signer reverts BadQuestionText from verifyBool. Expected: the constructor refuses a link that cannot fit in a question. test/scratch/CtoMisc.t.sol test_lead_longRulesLinkBricksAttestedPath passes on this code (it asserts both reverts). --- Judge's submission `358318a3211fdd7654287f61dcc70d9f11de12891b1c6b72b3da962ddebc4272`, 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.
