Done. The Blox (BLOX) custom token is built, tested, documented and committed on main.

What was delivered

• src/BloxToken.sol: OpenZeppelin v5.4.0 ERC20 + ERC20Permit, name Blox, symbol BLOX, 18 decimals. The constructor mints the full 1,000,000,000 BLOX once to the deployer, which is the ProjectFactory at launch. No constructor arguments, no owner, no mint, no pause, no blacklist, no fee, no proxy, no external calls in the constructor.
• test/BloxToken.t.sol: 22 tests covering metadata, exact supply to the deployer and not to tx.origin, launch flows arriving whole, fuzzed supply conservation, revert paths, the same admin and privileged selector sweeps the protected floor runs, a DELEGATECALL/CALLCODE/SELFDESTRUCT opcode scan, and permit success, wrong signer, expiry and replay.
• foundry.toml pins solc 0.8.26 with bytecode_hash none and no ffi or filesystem access. forge-std and a minimal OpenZeppelin subset are vendored as ordinary files under lib, with provenance notes.
• README.md documents assumptions, launch parameters, the after-launch section (nothing to set) and operational responsibilities.

Logo, exactly as required

The profile picture of @blox_imd was resolved to X's image host and the original upload was downloaded unmodified. It is committed as assets/logo/blox.jpg and its IPFS CID was computed locally two independent ways, which agreed. The token exposes the URI and the file's SHA-256 on chain, and assets/token-metadata.json points at the same file. Nothing was generated, edited or delegated.

Limitation reported: this machine has no IPFS pinning credentials, so the file is content-addressed but not yet pinned. The URI is already correct and resolves once anyone pins the committed file with the command in the README. The CID must come out identical, which proves the file was not altered.

Checks run

forge build, forge test (22 passed, also with an empty environment) and forge fmt --check all pass. Slither and Mythril were not available and were not run. No launch.json was written, as the manifest step owns it.

Done. I wrote launch.json for the accepted Blox (BLOX) launch and changed nothing else.

What the manifest says

• kind "custom_token", token contract BloxToken, name Blox, symbol BLOX, 18 decimals.
• Constructor arguments are an empty list. The accepted constructor in src/BloxToken.sol takes none and mints the whole supply once to msg.sender.
• totalSupply is 1000000000000000000000000000, matching the TOTAL_SUPPLY constant.
• No application contracts. The accepted tree contains only the token.
• Pool and economics copied verbatim from the launch terms: native ETH pair, fee 12500, tick spacing 60, the one-to-one initialPrice, poolBps 8800, 10 ETH opening cap, remainder to 0xf2816f3f05fac35577b1930ffd09b531b62628df.
• Notes describe the token's fixed supply, lack of privileged roles and fees, the unused launch placeholders, and the logo provenance. They record that the logo is the unmodified @blox_imd profile picture committed at assets/logo/blox.jpg, with its IPFS URI and SHA-256 held on chain, and that it is content-addressed but not yet pinned.

Checks

• A schema check confirmed only the allowed top-level keys, string uint256 values, numeric fee, tickSpacing and decimals, and notes under 4000 characters.
• forge build compiled cleanly and forge test passed all 22 tests.
• Git status shows launch.json as the only new file.

The review is complete. No defects were found in the Math Precision, Boundary or Numerical Gap areas, and the findings file records an empty list plus coverage for all four entry points and four invariants.

What the token is. BloxToken is unmodified OpenZeppelin v5.4.0 ERC20 plus ERC20Permit with one constructor mint of a compile-time constant. It has no external calls, no payable path, no receive or fallback, no fee or burn logic, and no owner. The only arithmetic in the whole surface is the library's balance and allowance updates.

What I checked and how.

• Vendored OpenZeppelin diffed byte-for-byte against the v5.4.0 tag. No differences.
• Supply constant evaluates to exactly 1e27 minor units and matches the README's manifest value; the aderyn large-literal lead is that constant and not a defect.
• Transfer and transferFrom edges run in a scratch suite: max-uint amount, supply plus one, self-transfer, zero-value, infinite versus max-minus-one allowance, allowance above balance, zero-address sender. All revert or conserve balances as the library intends.
• Permit edges: deadline equal to the block timestamp passes, expired fails, nonce gaps and replays fail, high-s and bad-v signatures and a zero owner all revert in ECDSA before any allowance is written, and the domain separator rebinds on a chain-id change.
• Runtime bytecode contains only STATICCALL for the ecrecover precompile, no CALL, CREATE, DELEGATECALL, CALLCODE or SELFDESTRUCT.
• Logo constants: the committed file's SHA-256 equals the on-chain constant and equals the original upload X currently serves as the avatar of @blox_imd. I recomputed the CIDv0 from scratch and it matches the on-chain URI.

One open item, not a code defect. The CID is not yet confirmed pinned. Public gateways rate-limited my check, and the README already names pinning as the remaining operational step.

The scratch directory was removed and the working tree is clean apart from the findings file.

The review is complete and the findings file is written. No defects were found.

Result: .imd-findings.json holds an empty findings list and nine coverage rows, one for each of the four listed entry points plus five invariants. The working tree is otherwise unchanged. The build, the existing 22 tests and forge fmt --check all pass.

What was checked in the assigned area

• Execution Trace. Traced transfer, transferFrom, approve and permit through OpenZeppelin v5.4.0 from entry to storage write. Each moves or sets exactly what its arguments say, reverts on the zero-address and insufficient-balance or allowance paths, and permit rejects replay, wrong signer, expiry, high-s and a zero owner without consuming a nonce. A scratch invariant run of 128,000 randomized calls across all four kept the sum of balances equal to total supply with zero reverts.
• Periphery. All 23 vendored OpenZeppelin files are byte-identical to the upstream v5.4.0 tag, and all 32 forge-std files are byte-identical to the pinned commit. Nothing in the library layer was altered.
• First Principles. The constructor mints the manifest supply once to the deployer with no other mint path. The ABI exposes no owner, pause, blacklist, burn-from or upgrade function, and the runtime bytecode contains no DELEGATECALL, CALLCODE or SELFDESTRUCT.

Logo requirement, verified against the live source. The committed file hashes to the same SHA-256 as the image served today from X's image host for the stated profile-image id, the on-chain LOGO_SHA256 constant matches it, and both the CIDv0 and CIDv1 recompute from those bytes. A public avatar mirror for @blox_imd returns the 400x400 variant of the same image, which ties the file to the account. The logo is the unmodified profile picture.

Static-analysis leads. Slither reported nothing. Aderyn's large-literal note on line 20 is the intended supply value and is confirmed by the existing tests.

Not reached. The protected test's pool seed and swap legs need Uniswap v4 code that is not in this tree, so they could not be executed here. Because the token applies no fee, burn or hook on any transfer, those legs reduce to plain transfers that the fuzz run already covers.

Review complete. The findings file is written and validated, the scratch test is removed, and the working tree is clean apart from the gitignored findings file.

Outcome: no economic, invariant or flow-gap defect in src/BloxToken.sol. The token is OpenZeppelin v5.4.0 ERC20 plus ERC20Permit with one constructor mint and nothing else.

What I verified:

• Supply and conservation. A 256-run Foundry invariant with 128,000 random transfer, approve/transferFrom and permit/transferFrom calls kept totalSupply at exactly 1e27 and balances summing to it. The ABI exposes no mint, burn, pause, blacklist or owner path.
• Launch flows. Every transfer path is the unmodified OpenZeppelin _update, so the swarm share, the pool seed and claims cannot arrive short. The floor's checks (supply to the factory, decimals 18, no DELEGATECALL, CALLCODE or SELFDESTRUCT) pass locally.
• Vendored code. All 23 OpenZeppelin files are byte-identical to upstream v5.4.0 at the commit the VENDORED note names.
• Logo. The committed file is byte-identical to the original upload X serves for the current profile image of @blox_imd, and the CID recomputes correctly from those bytes.

Findings written to .imd-findings.json:

1. Low. The on-chain logo URI points at a CID that no IPFS node currently provides. The IPNI index returns 404 and network-fetching gateways time out. The fix is operational: pin the committed file unchanged and confirm the same CID. The builder's README already discloses this.
2. Info. Permit can be front-run by a third party holding the signature, which reverts a caller that bundles permit with transferFrom. This is inherent to EIP-2612 and is for integrators, not a token change.

Coverage records all four entry points as holding, plus five invariant rows covering supply, constructor behaviour, vendored integrity, logo provenance and launch-flow exactness.

Review complete. The findings file is written and the tracked tree is unchanged.

Result: no defects in the Access Control, Trust Gap or Asymmetry areas. The findings list is empty, with ten coverage rows recorded in .imd-findings.json.

What I verified:

• Permission model. The only code outside OpenZeppelin is a constructor that mints the fixed supply to msg.sender. The compiled ABI exposes exactly the four listed state-changing entry points. The storage layout has no owner, admin, pauser or blacklist slot, and plain ETH, unknown selectors, burn, owner() and renounceOwnership() all revert.
• Library integrity. All 23 vendored OpenZeppelin files are byte-identical to upstream v5.4.0 at the stated commit. Four core forge-std files match their stated commit too. No hidden privileged path was injected.
• Asymmetry. The approve, permit and transferFrom paths all write allowance through the same internal function and emit Approval. Infinite allowance is not decremented, which is documented OpenZeppelin behaviour. Self-transfers conserve balance.
• Permit. Tampered parameters, malleable high-s signatures, contract wallets and replay all revert. A third-party relayer can only set the allowance the owner signed. The domain separator binds chain id and contract address.
• Logo requirement. The live X profile image downloaded today hashes to exactly the committed file and the on-chain SHA-256 constant. The IPFS CIDv0 recomputed from those bytes matches the on-chain URI. The file is not yet pinned, which the README already reports as a limitation.

One trust assumption is recorded rather than reported: anyone can front-run a permit, which makes an integrator's batched call revert without moving any value. That is inherent to ERC-2612.

Tools run: forge build, forge test (22 existing tests pass), a scratch suite of 9 additional tests that passed and has been removed, and network fetches for the library diff and image hash. Slither and aderyn output was tool-provided only. The single aderyn lead is the intended supply constant.

Added failure-path, permit fuzz, and stateful invariant tests. Only test/ changed.

Verified:

• forge build passes.
• forge test --offline: 69 passed, including 32,768 invariant calls.
• Three offline logo checks pass.

The logo matches its documented image URL byte-for-byte. X blocked confirmation of the account’s current profile-picture selection; that limitation is documented in the test notes.

The review is complete. The findings file is written at .imd-findings.json, no source files were changed, and the scratch test was removed.

Outcome: no code defects. The token is OpenZeppelin v5.4.0 ERC20 plus ERC20Permit with a single constructor mint, and the four entry points all hold.

What I verified:

• Build and tests. The project compiles under solc 0.8.26 and all 69 existing tests pass, including the invariant suite. Formatting check passes.
• Vendored library. Every file under lib/openzeppelin-contracts is byte-identical to upstream v5.4.0 at commit c64a1edb.
• Supply and deployability. The constructor takes no arguments, matching the manifest's empty list, and mints exactly the manifest supply to the sender once. Runtime bytecode has no DELEGATECALL, CALLCODE or SELFDESTRUCT, and both creation and runtime sizes are far under the factory's limits.
• Logo. The committed JPEG is byte-identical to the original profile image X serves for @blox_imd today, and I recomputed its CIDv0 independently and got the on-chain value.
• Manifest. Only schema keys, correct types, lowercase addresses, contract name within 32 characters, notes within 4,000 characters, and pool and economics equal to the launch's values.

Findings kept, both reproduced from the economics specialist and merged with nothing else since the other three areas reported none:

1. Low: the on-chain logo URI points at a CID no IPFS node provides yet. The IPNI index returns no provider and gateways time out or return 504. This is operational, not a code defect, and is disclosed in the README and manifest notes. The fix is to pin the committed file unchanged before publication.
2. Info: permit can be front-run by anyone holding the signature, which reverts a caller that bundles permit and transferFrom. I reproduced it in a scratch Foundry test. It is inherent to EIP-2612 and no change is proposed.

Coverage records all four entry points, plus the constructor and supply invariant and the manifest, with one finding reference on permit.
