#1254Audit flowClaude1 finding · 1 lowThe review is complete. One Low finding is recorded in
.imd-findings.jsonwith a failing Foundry proof undertest/scratch/. Nothing critical, high or medium survived verification.What I checked
I read all four contracts, the deploy scripts, the full unit suite and the fork test, then traced the four changed areas against the Pashov, x-ray, Trail of Bits and ethskills checklists. The 57 unit tests pass, and the fork test passes against live Robinhood Chain state with all five stocks converting.
The finding (Low)
The 30-day fallback for a stuck stock is sized by the IMD/USDG depth reading even though a fallback never swaps. In an abandoned IMD/USDG pool, an attacker repeats the 986abba2 finding-1 setup and sizes one narrow position so
maxConvert()reads 0.203 IMD, just above the 1% threshold. Measured cost is 0.36 IMD of recoverable capital. Every purchase then correctly reverts PriceOff, every stock becomes stuck, but each fallback round moves 0.04 IMD per stock instead of 4 IMD. That is a 100x slowdown, and with modest volume the reserves never catch up. The stale-feed path has the same clamp throughstockRoundLimit. No funds are lost. The minimal fix is to fall backmin(pendingConvert, MAX_ROUND_IMD / 5)wheneverstuckis true, keeping the depth caps for real swaps only.Confirmations on the four requested items
- IMD to USDG check. The math, decimals and overflow bounds are correct, and no attacker-reachable Panic inside
convertStockexists that would force a fallback. Pushing the IMD/ETH spot can block a round for one block, at roughly 2% of a swap that moves that pool more than 10%. Loosening the check to sell at a bad price only pays if the IMD/USDG pool is thin and the IMD/ETH manipulation fee is below the round's value, which is far from true at the depth the fork shows. Both pools being empty makes the check vacuous, but then IMD itself is dead. - Stuck rule. It cannot fire early on a healthy stock unless no purchase happened for 30 days, and then only a genuine failure in that call converts one round to IMD. Nothing an outsider does can reset
waitingSincewithout a real purchase, and no path lets a stuck stock avoid falling back when a caller supplies full gas. - Claim ordering and tags. Expiry runs before flush and convert, so from-pool tags are exact at that point. No distribution can run inside a foreign unlock, so borrowed tokens never shed their tag. The only user code that runs inside a router unlock is an ETH
receive()on the sell path, after the seller is already active. - Emptiness threshold. Behaves as described, with the throttle above as its one gap.
Nothing broke elsewhere. Solvency holds for all six assets on every path, including the fallback and reverted purchases. The flash-borrow guards, the 100,000 minimum, expiry boundaries and the no-external-call property of transfers are intact.

#1464Audit mathClaude3 findings · 1 mediumReview complete. The findings file is at the repository root, source files are untouched (
git diffis empty), and the only new path iscontracts/test/scratch/, which is mine.Outcome. One medium finding with a Foundry proof, two info findings. The four changed areas you asked about hold up, with one gap in area 2.
Findings written to
.imd-findings.json- Medium: the 30-day stuck fallback pays only the pool-clipped
imdIn. The rule promises "one capped round (4 IMD) at a time, whatever blocks it", but on the stale-feed and PriceOff paths_fallBackToImdgets an amount already clipped tomaxConvert()/5andstockRoundLimit. Once real liquidity has left a pool, a position costing about one token (80 IMD of virtual depth, or ~27 USDG in a 0.3% stock pool) keeps the pool just above the 1% emptiness threshold. At a made-up price every round is PriceOff, so an abandoned stock pool's reserve is frozen for 30 days where a truly empty pool is paid at once, and afterwards falls back at 0.06 to 0.10 IMD per round instead of 4. The proof test fails on this commit and passes with a three-line change: usemin(pending, MAX_ROUND_IMD/5)on the stuck paths. The live IMD/USDG pool is concentrated, with only 1.3% of its liquidity below tick -263790, so this regime also arises with no attacker if IMD drops below about $3.4. - Info: v4 protocol fee is on. Live slot0 reads show a 0.1% protocol fee on IMD/USDG, GME/USDG and IMD/ETH (25 pips on NVDA). The tolerance checks subtract only the LP fee, so effective margins are 9.9% and 2.9%. Not exploitable.
- Info: README line 130 still says conversions have "no minimum output" and quotes ~19,750 IMD depth. Live depth is ~8,840 IMD, 4x above the ~2,200 IMD sandwich break-even.
Confirmed, with live numbers (block 82538953, IMD ≈ $8.15)
- First-hop check. The IMD/ETH reference is 88% full-range liquidity (25,700 IMD / 82 ETH virtual). Loosening it enough for a 50% discount on a 20 IMD round would mean selling ~8,600 IMD at 1% fee each way, for a gain under 10 IMD. Blocking it costs ~0.08 ETH per block and only delays rounds. A made-up IMD/USDG price is caught. After the fork test's 2.2 ETH buy the gap was 9%, so a ~4.5 ETH buy via the ETH route pauses conversions until arbitrage, as you accept.
- Stuck rule.
waitingSinceonly ever moves to now or 0, so nobody can age a healthy stock. The one gap is the medium finding above. - Claim ordering and epoch tags.
_recycleruns before flush, and the only_creditreachable inside a foreign unlock is router-only, so borrowed tokens can never see a tag lapse. Correct. - Empty-pool threshold. Works as stated for the IMD/USDG pool; the cliff it creates is the medium finding.
Solvency accounting for all six assets, the flash-borrow guards, the 100,000 minimum boundaries, expiry boundaries (7 days, 4-day oracle age, 30-day stuck, 1-minute interval) and the no-external-call property of transfers all check out. All 58 unit tests and the fork test pass. Not run: Slither, long fuzz campaigns beyond the configured 256 runs.

README "Known risks" still says conversions have no minimum output and quotes a launch depth of ~19,750 IMDREADME.md:130
Line 130 states that conversions "run at the pool price of the moment and have no minimum output", which contradicts line 30 and the code: since f1d5def3 finding 1 every stock purchase must receive at least 97% of the Chainlink-implied amount (minStockOut) and since 986abba2 finding 1 the IMD -> USDG hop at least 90% of IMD's IMD/ETH + Chainlink value (minUsdOut), both enforced in unlockCallback.
The same line gives the IMD/USDG depth as about 19,750 IMD at launch; the live pool (block 82538953) has 8,840 IMD of virtual depth at the current price, so the margin above the ~2,200 IMD sandwich break-even is about 4x.
Fix: reword the risk item to describe the two oracle-bounded minimums and the 10%/3% residual tolerance, and refresh or drop the depth figure (also in the MAX_ROUND_IMD NatSpec at contracts/src/CompanyToken.sol line 123).
Read README.md line 130 against contracts/src/CompanyToken.sol lines 788-791 (two PriceOff minimum-output checks). Expected: documentation matches the enforced minimums; actual: it says there is none.

#29Audit economicsClaude2 findings · 2 lowThe review is complete. The findings file holds two Low findings, each with a self-contained Foundry proof that fails on the current code. No source files were changed; only
contracts/test/scratch/and.imd-findings.jsonwere added.What I confirmed on the four changed areas
- Question 1, the first-hop check. A round cannot sell at a made-up low IMD/USDG price: the floor comes from the IMD/ETH pool plus Chainlink, and loosening it is expensive at live depth. On the fork at block 82539044, selling 8,000 IMD into IMD/ETH lowers
minUsdOutby 42% and 64,000 IMD by 93%, costing about 1% in fees each way, against a gain capped at 20 IMD per round. Blocking is cheap but useless: a 4 ETH buy brings the floor to 7.98 USDG against about 8.07 paid, and 8 ETH to 8.73, so any 5 to 8 ETH buy pauses conversions until arbitrage. That matches what AUDIT.md section 9 already accepts. - Question 2, the stuck clock. Nobody can keep a stuck stock from falling back, and a stuck stock cannot be un-stuck without a real purchase. But the clock can fire early on a healthy stock, which is finding 1.
- Question 3, claim ordering and the transient epoch. Correct. A distribution can only happen inside a router's own unlock, and the only user code that runs there is the ETH-sell
receivecallback, which runs after the flush, so borrowed tokens are always tagged with the current epoch. The lapsed-tag path requires real capital and costs more than the accepted gift variant. - Question 4, the empty IMD/USDG pool. The "nothing is swapped, only stuck stocks fall back" rule holds for an actually empty pool, but a made-up high price defeats it, which is finding 2.
Findings
- Low, CompanyToken.sol line 717. The 30-day clock keeps running while nobody calls. After a quiet month, the first call that meets a transient block pays a healthy stock's round as IMD: a weekend-stale feed, or a PriceOff right after a large ETH-route buy. Since the fallback does not move the clock, anyone can repeat it every minute and drain the whole reserve into IMD over a weekend. Value is preserved as IMD, so this is griefing of the promised stock exposure, but it contradicts guarantee 7 ("only on a real failure").
- Low, CompanyToken.sol line 726.
stockRoundLimitprices USDG in IMD at the IMD/USDG spot read in the same transaction. The live pool is concentrated and can be driven out of range for about 110,000 USDG of swap volume (roughly 1,000 USDG fee each way). A dust position holding about 35 IMD at a price 50,000 times fair then makesmaxConvertread a full round while every deep stock pool reads as empty, and all five stocks' rounds are credited as IMD at once, with no swap and no 30-day wait. Re-pricing the limit alone is not enough, because the swap would then fail with Slippage and fall back through the catch anyway.
Solvency, flash-borrow guards, 100,000 minimum, expiry, and transfers held under everything I traced: the six-asset accounting is conserved on every path including the new fallback paths, claim and recycle refuse mid-unlock, distribution cannot run mid-unlock except from a router, weights and corrections stay consistent, and
_transfermakes no external calls.Test runs: the full suite passes (58 tests), the live fork test passes, and the two proof files fail as reported. Not covered: Slither or long fuzz runs, and the stock tokens' real blocklist behaviour, which the fork test does not exercise.

#528Audit permissionsClaude3 findings · 1 lowReview complete. The findings file holds three entries, no tracked file was changed, and only the scratch directory is new.
Outcome. The four changes since 986abba2 hold up. I found one Low on the new stuck rule and two informational notes. No solvency, flash-borrow, minimum-holding or expiry regression, and transfers still make no external calls.
What I verified
- First-hop check (question 1). It can be pushed in the same transaction, but only at a cost. On the live chain the IMD/ETH pool is effectively full range, with about 77 ETH and 22,450 IMD of real tokens. Moving the spot 10% costs about 0.04 ETH of fees per direction and only blocks a round. Forcing a made-up price needs the ETH side bought out plus the USDG side of IMD/USDG, for at most 20 IMD per minute of gain, so it is unprofitable. The IMD/USDG pool now holds about 8,900 IMD of virtual depth, four times the 2,200 IMD threshold where in-tolerance sandwiching turns profitable. Worth watching, since it was 19,750 at launch.
- Stuck rule (question 2). The clock cannot be shortened or started early. Reserve top-ups do not restart it, and only a real purchase moves it. A stuck stock cannot be kept from falling back except by a genuine fair-price purchase, which is the desired outcome.
- Claim ordering and tag epochs (question 3). Expiry before flush is strictly tighter for the protocol. Every path that bumps the epoch is unreachable while another caller holds the PoolManager unlocked, so borrowed tokens never see a tag lapse. The only lapse that helps a wallet is the capital-backed variant already accepted in AUDIT.md section 9.
- Empty IMD/USDG rule (question 4). Confirmed by reading and by a 400-seed randomized run over stale feeds, blocked recipients, pool drifts, donations, third-party trades and 31-day gaps. Solvency of all six assets and the pending/waitingSince invariant held in every step.
- The full suite and the live fork test pass at the pinned commit.
Findings written
- Low. The stuck rule measures time without a purchase, not time when a purchase was impossible. After any 30-day gap with no claim or convert, one transient skip pays every stock's round as IMD. A 4 ETH buy through the ETH route or a deliberate IMD/ETH swap in the same transaction triggers it, 20 IMD per minute while held. Holders lose no value. Suggested fix keeps the no-keeper design by requiring a recorded failed attempt at least a day earlier.
- Info. The README claim that a same-transaction manipulation "can't pass this, however thin the pool" is only true for the stock hop. The fork test comment still says 5% tolerance.
- Info. No unit test covers the first-hop drift skip or a stale ETH/USD or USDG/USD feed. I verified both paths behave correctly with scratch tests.

The only test of minUsdOut is the made-up-price position in an emptied IMD/USDG pool. Nothing in the suite exercises the ordinary case the brief asks about: the IMD/ETH spot drifting more than 10% from IMD/USDG (every stock must skip with PriceOff and nothing may fall back before 30 days), nor the ETH/USD or USDG/USD feed being stale (both are read in _feedsFresh and minUsdOut and hold all five stocks).
I verified both paths behave as designed with scratch tests (all stocks held, owed[0] unchanged, one round per stock paid as IMD only after 30 days), so this is a coverage gap, not a defect.
Suggested tests: (1) buy 1,000 IMD twice, warp 1 minute, swap 600 ETH -> IMD in the IMD/ETH pool, convert(): assert out[s] == 0 and pendingConvert[s] unchanged for all s; (2) set ethFeed.updatedAt = now - 5 days with the others fresh, convert(): same assertions; same for usdFeed.
State: the test suite at this commit.
Input: grep for a test that moves the IMD/ETH pool price or sets ethFeed/usdFeed stale before convert().
Expected: at least one such test.
Actual: none (ethFeed and usdFeed are only ever set fresh by _refreshFeedsExcept; the IMD/ETH pool is only used by the ETH router tests).

#475Claude6 findings · 1 mediumafterAudit math, Audit permissions, Audit economics, Audit flowThe review is complete. The findings file is written at the repository root, the source tree is unchanged, and every snippet and proof was checked against the tree.
What I did
I read the four contracts, the tests, AUDIT.md and the README, built and ran the full suite (58 tests pass) and the live fork test against Robinhood Chain (passes). I then reproduced each specialist finding with my own Foundry tests under
contracts/test/scratch/, verified two on-chain claims withcastagainst the live PoolManager, and merged duplicates.Findings kept, in
.imd-findings.json(6 findings, 3 with proofs)- Medium, stuck fallback throttled. Merged audit_math and audit_flow. On the stale-feed and PriceOff stuck paths the fallback moves the swap-clipped amount, so a 0.36 IMD dust position in an abandoned IMD/USDG pool shrinks the 30-day fallback from 4 IMD to 0.04 IMD per stock. Reproduced exactly (0.203 IMD total instead of 20). I also confirmed the proof passes under the obvious fix by temporarily patching and restoring the contract.
- Low, quiet month then transient skip. Merged audit_economics and audit_permissions. After 31 idle days, a feed one second past the 4-day limit, or a same-transaction IMD/ETH push, pays healthy stocks as IMD. Both reproduced, plus the repeat-every-minute drain.
- Low, exhausted-pool immediate fallback. From audit_economics, widened: a single-sided IMD position with no USDG triggers an immediate, non-stuck-gated fallback of all five stocks, both at a made-up high price (via the stock-pool limit) and at the true price (via Slippage). Both reproduced.
- Info, v4 protocol fee. Verified on-chain: 0.1% protocol fee on IMD/USDG and GME, 25 pips on NVDA. The tolerance math subtracts only the LP fee.
- Info, documentation. Merged the two README findings: "no minimum output", "however thin the pool", the stale 19,750 IMD depth figure (live depth is about 8,550 IMD), and the fork test's "5% tolerance" comment.
- Info, test coverage. No unit test for the first-hop drift skip or a stale ETH/USD or USDG/USD feed.
Dropped or changed
Nothing was dropped. Severity for the throttle finding is set to medium (the stronger of the two specialists' ratings) because holders' stock share is withheld rather than paid in another asset, which is worse than the two low findings. No new defects beyond the Slippage variant were found in solvency, the flash-borrow guards, the 100,000 minimum, expiry, or the no-external-calls-in-transfer property.
