Implemented MoneyCanBuy.fun (YOLO): 1 billion tokens, 18 decimals, minted once to the deployer.

Offline build, all 34 reported tests, formatting, and Slither checks pass, including the required fuzz seed. No High or Medium findings.

Vendored dependencies, deployment documentation, and validation details are included in README.md, DEPENDENCIES.md, and REVIEW.md.

Created launch.json matching MoneyCanBuyToken, its exact supply, empty constructor arguments, and the required pool and economics values. No application contracts are listed.

forge build and forge test passed with the supplied fuzz seed: 34 tests, zero failures. Only launch.json changed outside scratch.

The review is complete. The findings file is valid JSON and no tracked file was changed.

Result: no defects found. The token is a four-line wrapper around the unmodified OpenZeppelin v5.0.2 ERC-20, and every path reachable through the three listed entry points behaves as the brief requires.

What I verified, against the Execution Trace, Periphery and First Principles guides:

• Execution trace of each entry point. approve writes only the allowance and rejects a zero spender. transfer rejects a zero receiver and an insufficient balance before any write, and moves the exact amount. transferFrom spends allowance first, but any later revert rolls that write back, so no partial state survives. The unlimited allowance does not decrease, which is the standard and documented semantics.
• Constructor and supply. The constant is exactly 10^27 minor units, minted once to the deploying factory, with no constructor arguments and no payable path. The aderyn large-literal lead is a compile-time constant and not a defect.
• Privileged surface. The compiled ABI exposes only the ERC-20 functions plus the supply constant. There is no mint, burn, pause, blocklist, owner, initializer or upgrade entry, so supply cannot grow and no one can move or freeze a holder.
• Periphery. The five vendored OpenZeppelin files hash byte-for-byte to the upstream v5.0.2 tag. A reachable-block walk of the runtime finds no DELEGATECALL, CALLCODE or SELFDESTRUCT, and the code makes no external call, so the launch seed, swaps and distributor claims cannot be reentered or taxed.
• Checks run. The project builds with solc 0.8.26 and all 34 tests pass with the seed named in the README.

Coverage in .imd-findings.json has eight rows: the three listed entry points plus five invariants, all marked holds. The one thing not reviewable yet is launch.json, which does not exist in the tree because the manifest step has not run. The README's stated manifest values agree with the compiled token.

The review is complete and the findings file is written. No source file was changed.

Outcome: no defects found in the Economic Security, Invariant or Flow Gap areas. .imd-findings.json holds an empty findings list and nine coverage rows, one for each of the three listed entry points plus six invariants and economic flows I checked.

What I verified

• The token is a stock OpenZeppelin v5.0.2 ERC-20 with one constructor mint of exactly the brief's supply to the deployer. All five vendored library files are byte-identical to the upstream v5.0.2 archive.
• Launch flows arrive whole. A scratch Foundry test modelled the 10/80/10 split, a PoolManager-style pull through transferFrom, claim and trade round-trips, and a 9-holder conservation fuzz. All passed, and the repository's own 34 tests pass too.
• No supply growth path exists. The ABI exposes only the standard ERC-20 functions and the supply constant, there is no receive or fallback, and mint-style calls from the factory address revert.
• No privileged power exists to move or freeze a holder. The factory has ordinary holder rights only.
• The compiled runtime and creation code contain no reachable DELEGATECALL, CALLCODE or SELFDESTRUCT.
• The aderyn large-literal lead on line 10 is the correct 1e27 supply, not a defect.

Not covered: no launch.json exists in the tree yet, so no manifest was checked. The protected floor tests that need the network's launch contracts and Uniswap v4 harness were read, not executed.

The review is complete. Findings are written to .imd-findings.json with an empty findings list and a full coverage record. No source files were changed, and the scratch tests were removed. The working tree shows only the untracked findings file.

Result: no defects in the Math Precision, Boundary or Numerical Gap areas.

The token is a 15-line fixed-supply ERC-20 inheriting the vendored OpenZeppelin ERC20. I confirmed by SHA-256 against the upstream v5.0.2 tag that all three vendored files are byte-identical, so the arithmetic surface is exactly the audited library plus one constant.

What I checked, each against a concrete input in a Foundry scratch test (16 tests, all passing):

• Supply constant. The expression at src/MoneyCanBuyToken.sol:10 is a compile-time checked constant and evaluates to exactly 10^27. This closes the aderyn large-literal lead as a non-defect. Decimals return 18 and the contract identifier is 16 characters.
• Transfer boundaries. Zero, 1 wei, full balance, balance plus one, and max uint all behave as intended. A self-transfer of the whole balance keeps it unchanged. Transfer to the zero address reverts even at zero amount.
• Allowance boundaries. An exact-amount spend reaches zero and the next 1-wei spend reverts. An allowance one short reverts and is left intact. Max-uint allowance persists while max-minus-one decreases. A balance failure inside transferFrom rolls the allowance change back. A zero sender reverts before any state change.
• Conservation invariant. The sum of balances equals the fixed supply under a 1000-run fuzz, and the 10/80/10 launch split is exact with no remainder (100M, 800M, 100M tokens).
• Payable and external boundaries. There is no receive, fallback, payable function, external call, division, cast, or sentinel branch in the token, so the Numerical Gap seams have nothing to combine.

Coverage rows are given for all three listed entry points plus the constructor and two invariants, every one marked holds. Nothing in my area was left unreached. The protected admission tests that need the network's Uniswap v4 harness were read but not run here, as they cannot build in this repository.

The review is complete and .imd-findings.json is written. The working tree is clean apart from the gitignored findings file and scratch test.

Result: no defects found in the assigned area. The token is a 15-line fixed-supply ERC-20 with no roles, so the Access Control, Trust Gap and Asymmetry guides have almost no surface to bite on. I verified that rather than assuming it:

• Access control. The compiled ABI exposes only approve, transfer, transferFrom, the views, and the supply constant. There is no owner, mint, burn, pause, blocklist, initializer, upgrade, receive or fallback. Unknown selectors and ETH revert for both the deployer and a stranger. The deployer (the factory under launchCustom) has ordinary holder rights only. Supply is minted once, to msg.sender, with no other path to _mint or _burn.
• Asymmetry. transfer and transferFrom reach the same _transfer. The only extra write in transferFrom is the allowance decrement, which rolls back when the balance check reverts. Confirmed with a scratch test.
• Trust gap. No setters, fees, pricing or recipient parameters exist, so none of the cross-lens seams are reachable. Launch economics live in the factory and manifest, outside this tree.
• Dependency integrity. I downloaded the upstream OpenZeppelin v5.0.2 archive. Its hash matches DEPENDENCIES.md and all six vendored files are byte-identical. The runtime bytecode has no reachable CALL, DELEGATECALL, CALLCODE, CREATE or SELFDESTRUCT.

One info-level note recorded. Zero-value transferFrom needs no allowance, so anyone can make the token emit Transfer(victim, attacker, 0). That is EIP-20-mandated behaviour and moves nothing on-chain. I logged it with a reproduction so the judge sees it was considered, and recommended no change.

Coverage. All three listed entry points have rows (two holds, one finding pointing at the info note), plus rows for the constructor, the absent admin surface, the opcode scan, dependency integrity and the trust-gap seams. The only unreached row is launch.json, which does not exist yet because the manifest step has not run.

The project's own suite passed (34 tests) and the aderyn large-literal lead is a style note on the supply constant, not a defect. The protected Uniswap v4 admission tests could not run locally since v4-core is not vendored; that is the network's later step.

Added 22 edge-case and fuzz tests covering failed transfers, allowance rollback, revocation, and caller authorization. Expanded invariants to verify balances, allowances, fixed supply, and holder transferability.

forge build and forge test pass offline with the required seed: 56 reported tests, including 32,768 invariant calls.

Only test/ changed. No implementation defects found.

The review is complete and .imd-findings.json holds the result. The repository tree is unchanged apart from the findings file and my scratch test, both of which are ignored by git.

Outcome: no defects found. The token is a bare OpenZeppelin v5.0.2 ERC-20 whose only custom code is a parameterless constructor minting the fixed supply to the deployer.

What I verified:

• Vendored library integrity. I downloaded the upstream v5.0.2 archive, confirmed its SHA-256 matches DEPENDENCIES.md, and compared all five vendored Solidity files byte for byte. All identical.
• Specialist findings. Four areas reported nothing. The permissions specialist's single info note reproduces exactly as stated. A zero-value transferFrom with zero allowance succeeds and emits a Transfer event, because the allowance check is "less than" rather than "less than or equal". This is required by EIP-20 and documented in the README. I kept it as an info trust note with no change recommended. Nothing else to merge.
• Launch floor checks I could run locally. A CREATE2 probe deploy leaves the probe holding the whole supply, the 10% distributor flow and onward claim arrive whole, supply stays fixed, the factory cannot pull from a holder without allowance, the reachable-opcode walk finds no DELEGATECALL, CALLCODE or SELFDESTRUCT, and both runtime and initcode are far below the size limits. The project's own 56 tests and my 5 scratch tests all pass.
• Manifest. Constructor args are empty to match the parameterless constructor. Name, symbol, decimals, total supply and contract name all agree with the source. The pool and economics blocks match the launch's reference values.
• Static analysis. Slither reported nothing. Aderyn's large-numeric-literal lead is the constant 1_000_000_000 * 10 ** 18, which equals the manifest supply and is not a defect.

The coverage record answers all three entry points plus three invariant rows. The pool seed and swap tests from the protected floor need the network's Uniswap v4 harness, which is not vendored here, so I did not execute them. Since the token has no transfer logic beyond the unmodified library, nothing in those flows can differ from an ordinary transfer.
