Implemented Pegzeus (PEGZEUS): 1 billion tokens, 18 decimals, minted once to the deployer, with no transfer fees.

Dependencies are vendored for offline builds. README documents deployment parameters, assumptions, and operational responsibilities.

Validation passed with Solidity 0.8.26:

• forge build
• forge test: 29 tests passed, including fuzz and invariant tests
• forge fmt --check

Tests also passed with an empty environment and four threads. The external launch/Uniswap harness requires launch infrastructure and configuration and was not run locally.

The review is complete and the findings file is written. Here is the recap.

Result: no defects found. The findings file at .imd-findings.json holds an empty findings list and eight coverage rows, all holds. The working tree is otherwise unchanged. The scratch test was removed.

What the token is. Pegzeus is a 16-line contract that inherits OpenZeppelin ERC20 and mints the full supply to the constructor caller. There is no owner, no role, no setter, no hook, no fee branch and no exemption list. The compiled ABI exposes only the standard ERC-20 functions plus one constant view. The runtime bytecode contains no call, create, delegatecall, callcode or selfdestruct opcodes, and there is no receive, fallback or payable function.

What I checked, by guide.

• Access Control: the permission map has exactly one gate, the allowance check inside transferFrom. An independent probe showed the factory, the deployer, a spoofed tx.origin and a stranger all fail to pull from a holder without allowance, and every common admin selector reverts for every caller. Under CREATE2 factory deployment the factory, not tx.origin, receives the supply.
• Trust Gap: with no privileged actor and no caller-class branch, none of the four seams exist. Launch flows move exactly the requested amount, which the author's local launch-flow test confirms. The Uniswap v4 swap leg was not executed locally because v4-core is not vendored. Only the protected harness can run it.
• Asymmetry: transfer and transferFrom share one internal path. approve and allowance spending share one internal writer with identical zero-address checks. The only difference is OpenZeppelin's documented omission of the Approval event on spend, which is not a defect.

Supply-chain check. The vendored OpenZeppelin files are byte-identical to the upstream v5.1.0 tag, and the archive digest matches the one recorded in the repository. This was the one place a hidden privilege could have entered, and it is clean.

Static analysis leads. Slither reported nothing. Aderyn's large-literal note is the supply constant, which equals 10^27 as the manifest requires. Not a defect.

Open item for the launch operator, not a finding. The protected harness swap test still has to run in the launch infrastructure with the real pool manager, since it cannot run here.

Created launch.json matching Pegzeus’s constructor, exact supply, requested economics and paired currency.

Manifest checks passed. forge build succeeded; forge test passed all 29 tests. Only launch.json changed outside scratch artifacts.

Review complete. The Pegzeus token's control flow is sound; the findings file holds one low-severity documentation defect and a full coverage record.

What I produced

.imd-findings.json in the repository root, with one finding and eight coverage rows. The scratch test directory was removed, and no other file changed. The reviewed tree is otherwise clean.

Finding (low)

The README's sample manifest fragment sets the token contract field to the fully qualified artifact path. The LaunchManifest schema only admits a bare identifier, so a manifest copied from that fragment is rejected at validation. The fix is to use Pegzeus as the value. Every other field in the fragment matches the code.

What holds, and how I verified it

• Execution trace. Each of the three listed entry points was traced through OpenZeppelin's _approve, _transfer, _spendAllowance and _update. Balance debit and credit happen in one step, total supply is untouched, zero addresses are rejected, failed transfers roll allowance back, and no external call or callback exists.
• Periphery. The vendored OpenZeppelin files are byte-identical to the upstream v5.1.0 tarball, whose hash matches the recorded digest. There is no submodule and no assembly.
• First principles. A CREATE2 factory, not tx.origin or the calling EOA, receives the whole supply. The constructor refuses ETH. The token reverts on empty calldata, unknown selectors and ETH. An independent opcode scan of the runtime found no CALL-family, DELEGATECALL, CREATE or SELFDESTRUCT. The ABI exposes no mint, burn, owner, pause, blacklist or upgrade entry point. The supply constant equals the manifest's supply string.
• Tests. The project's 29 unit, fuzz and invariant tests pass. My scratch suite of 6 additional inversion tests passed and was deleted afterwards.

Trust assumptions and limits

The standard ERC-20 approve race exists and is documented in the README. It is inherent to the design and not reported as a defect. The protected harness could not be run locally because it needs Uniswap v4 sources and launch environment variables that this tree does not carry. Slither and aderyn output from the verifier reported nothing above a large-literal note, which I confirmed is the correct supply constant.

The review is complete and .imd-findings.json holds the result: zero defects and nine coverage rows.

What I checked. The token is a 16-line fixed-supply ERC-20 on OpenZeppelin v5.1.0 with no overrides. I traced the three state-changing entry points against the Math Precision, Boundary and Numerical Gap guides, and confirmed each with a scratch Foundry suite that I ran and then removed.

• Math precision. The supply constant is a compile-time exact value of 10^27 that fits uint256, divides into exactly one billion whole tokens at 18 decimals, and appears as a literal PUSH in the creation code. The unchecked adds and subtracts in the inherited transfer path are bounded by the fixed supply, and the only checked addition runs once in the constructor. The aderyn "large numeric literal" lead is stylistic and not a defect.
• Boundary. Zero, self, full-supply, supply+1 and max-uint transfers behave correctly, with the expected ERC-6093 errors and no state change on revert. Allowance edges at exactly the value, max-1 and max behave as OpenZeppelin documents. The contract has no external calls, no payable functions, no receive or fallback, and no bytes decoding. The runtime contains no CALL, DELEGATECALL, CALLCODE, STATICCALL or SELFDESTRUCT.
• Numerical gap. Supply conservation holds under fuzzed transfer chains and the existing stateful invariant suite. The supply leaves ample headroom for the launch's basis-point split and for Uniswap v4's int128 delta and uint128 liquidity types.
• Dependency integrity. The five vendored OpenZeppelin files are byte-identical to the upstream v5.1.0 archive, whose SHA-256 matches the recorded digest, and are committed as plain files.

Not reached. Nothing within the assigned area was left unexamined. Pool pricing and seeding math live in the factory and deployer, outside this token, and I only confirmed the supply's fit for them.

No files other than .imd-findings.json were changed, and the scratch test directory was deleted after its run.

Review complete: no economic, invariant or flow-gap defects in the Pegzeus token. .imd-findings.json holds an empty findings list and coverage rows for all three entry points plus five invariant rows.

What I checked

• Source. The token is sixteen lines: stock OpenZeppelin v5.1.0 ERC20 with one constructor mint of 1e27 units to the caller. I confirmed the vendored ERC20 matches upstream v5.1.0 (the only differences from the v5.7.0 mirror are upstream comment and import-order edits). No owner, hooks, callbacks, mint or burn paths exist after construction.
• Economic Security guide. No oracles, external calls, fee or rebase behaviour, pausability or blacklist. Zero-address transfers and approvals revert per ERC-6093. ETH sent to the contract reverts. Privileged-call probes in the repo's tests and the protected harness all fail without moving balances.
• Invariant guide. Sum of balances equals total supply on every path, since the constructor is the only writer of supply. Allowance coupling in transferFrom is exact, with the unlimited allowance left untouched. The repo's stateful invariant suite passed at 128 runs, depth 64.
• Flow Gap guide. Every launch flow is a plain exact transfer, so the swarm share arrives whole, a sync/settle balance delta equals the amount sent, and swap take/settle amounts match. I fuzzed this with a settle-style receiver over random pool shares, actors and amounts at 2000 runs on two seeds. The one failure during that run was my own harness double-counting when the fuzzer chose the distributor address as the requester, not a token defect.

Build and tests

forge build --offline        ok (solc 0.8.26)
forge test --offline         31 passed, 0 failed (repo suite + invariant suite)
forge fmt --check            clean

Leads dismissed. The aderyn large-numeric-literal note points at a compile-time constant that equals the manifest supply exactly. Tokens sent to the token's own address strand, which is standard ERC-20 behaviour the README already documents.

No scratch files remain in the tree, and no project file was modified.

Added 13 boundary/fuzz tests and extended invariants to mix valid transfers with failure paths, checking supply, balances, and allowance rollback.

Validation passed offline: forge build and all 42 tests, including 16,384 invariant calls. Only test/ changed. No implementation defects found.

Wrote .imd-findings.json.

• One reproduced low-severity finding: README’s manifest example uses an invalid contract identifier.
• All three entry points marked holds.
• All 42 local Foundry tests passed.
• Protected seed/swap integration remains unverified because required infrastructure is absent.
