The whole request

Release Drip (ERC-20 symbol DRIP) on Sepolia as an evm_project: the fixed-supply launch token plus one application contract.

Token: Drip (DRIP), total supply 1,000,000,000 DRIP with 18 decimals, minted once to the deployer.

Application contract: TokenFaucet.

Currency: the faucet holds any ERC-20 donated to it; DRIP is the featured token. TokenFaucet takes the DRIP address as its only constructor argument (constructorArgs ["$token"]) and exposes it as featuredToken() for the site's default; it holds no DRIP at deploy (DRIP comes from swapping Sepolia ETH in the launch pool).

Payments in use SafeERC20.safeTransferFrom; there is no payable function and no owner, admin or withdraw-all path. donate and claim follow checks-effects-interactions and are nonReentrant. donate(token, amount) pulls amount and records the amount actually received (balance delta) as the donor's total for that token; zero received reverts. claim(token): each address may claim a given token once per 24 hours (block.timestamp >= lastClaim + 24 hours, first claim always allowed).

The claim amount is 100 whole tokens, 100 * 10^decimals() read through IERC20Metadata (tokens whose decimals() reverts or exceeds 30 are unsupported and claim reverts); if the faucet holds less, the claim pays whatever it holds, and an empty faucet reverts. Claims transfer directly to the caller. The claimable pool is simply the faucet's balance of that token, so tokens sent without donate() are also claimable and nothing is stranded.

Donations are final (donors cannot withdraw). Donors are listed per token without duplicates: donorCount(token), donors(token, offset, limit) (limit capped at 100; offset past the end returns empty), donatedBy(token, donor). nextClaimAt(token, account) and claimAmount(token) are views.

A Sepolia test toy: the README and the page say anyone can claim from many addresses (a test faucet, not a fair or valuable distribution) and that each token's own balanceOf and transfer are trusted, so a malicious token can only hurt its own pool.

Events: Donated(token, donor, amount), Claimed(token, claimer, amount). Tests (Foundry) must cover: the 24-hour cooldown at its exact boundary and per token, 6- and 18-decimal tokens, a partial last claim, an empty faucet, fee-on-transfer donations recorded net, donor de-duplication, and a reverting-decimals token.

The independent adversarial review must attack: reentrancy through a malicious token in donate or claim, decimals() manipulation to claim huge amounts, cooldown bypass across tokens, and donor-list growth being used to grief the paginated view.

Deploy through the project factory, then publish a one-page website to pick a token (DRIP by default, or paste an address), show the faucet balance and your next claim time, claim, donate (with an approve step) and page through the donor list. Lists come from contract views and events only (no backend, no indexer). Keep it to one small page; the static export has index.html in dist/.

Also approved

Sepolia (11155111) only. GitHub publication and IPFS hosting are approved. Launch token: a separate fixed-supply ERC-20, 18 decimals, no constructor arguments, exactly 1,000,000,000 minted to msg.sender, no mint or admin functions. The factory sends that supply to LP and rewards, so no application contract may need a launch-token balance at deploy. Application contracts are fully configured in nonpayable constructors using only address, uint, bool or bytes32 arguments (no strings, arrays, proxies, delegatecall or selfdestruct); anything else is set at runtime. No owner unless the request names one, and then it is $owner. No external oracles, VRF or keepers: randomness is commit-reveal or a future blockhash read within 256 blocks with a refund path. foundry.toml sets bytecode_hash = "none". The website is a static export with index.html in dist/. Site label lab-token-faucet.

Build DRIP and TokenFaucet (TokenFaucet takes constructorArgs ["$token"] as its featured token) with Foundry tests and an independent adversarial review, deploy them through the project factory, then build the one-page website against the live deployment.

The website brief

One static page, no framework beyond what the skill needs, reading the live deployment's ABI and address.

  3. Adversarial reviewAgent #351found 3 info

    Review complete. No blocking findings. All four requested attacks fail against the accepted source, and the manifest is correct. Findings are written to .imd-findings.json (three info-level observations, none reopening the work). No repository files were changed.

    What I ran

    • forge build, forge test, forge fmt --check and the ABI export check in the repo: 38 tests passed, exports match the compiled contracts.
    • Both protected floors from the pinned reads, executed in a scratch project against the real creation code with a simulated CREATE2 factory and Sepolia chain id: 8 of 8 passed.
    • Eight adversarial probes in a scratch project outside the repo, covering the attacks below plus malformed metadata and a mirror token.

    Requested attacks

    • Reentrancy through a malicious token. Fails. Both donate and claim share the OpenZeppelin guard, and the nested call from a token's transfer or transferFrom reverts with ReentrancyGuardReentrantCall in all eight outer/inner/same-or-other-pool combinations. balanceOf and decimals are declared view, so they run under STATICCALL and cannot mutate state. In claim, the next-claim timestamp is stored before the transfer. The only residue is read-only: during a donate callback, the donor views already show the tentative donor while donatedBy is still 0. That is confined to the token's own list and is rolled back on failure.
    • decimals() manipulation. Fails beyond the token's own pool. The nominal amount is capped at decimals 30 and then capped again by the faucet's balance of that same token, so the worst case is a token emptying its own pool, which the README declares as an accepted trust assumption. A token returning a word above 255 or empty return data reverts with empty data rather than UnsupportedDecimals, which is a message-quality observation only.
    • Cooldown bypass across tokens. Fails. The timestamp is keyed by token and account, and the tests cover the exact boundary, timestamp zero, and a second token not resetting the first. A mirror token that reports another token's balance cannot move that balance because the faucet never grants an allowance. Many-address claims are permitted by the spec.
    • Donor-list growth griefing the paginated view. Fails. donorCount is a single storage read and donors does at most 100 reads regardless of list size. A 1,005-donor list pages within a 500,000 gas budget in the repo test, and extreme offsets and limits cannot overflow.

    Manifest

    launch.json lists LaunchToken with no constructor arguments and one application contract TokenFaucet with ["$token"]. That matches constructor(address featuredToken_) in the source and in the exported ABI. The argument grants no role. The contract stores it as an immutable display default, never reads msg.sender in the constructor, has no owner, withdraw, pause, or upgrade path, and every non-view function is nonpayable. Token metadata, decimals, and supply match the workflow, contract names are unique and do not use the reserved name, and the pool fields match the Sepolia guidance.

    Test coverage note

    The suite exercises every case the workflow lists, including fuzzed reentrancy and a stateful invariant with an independent model. The only untested edge I found is malformed decimals() return data, which is recorded as the first info finding.

    • infoMalformed decimals() return data reverts with empty data instead of UnsupportedDecimalssrc/TokenFaucet.sol:79

      claimAmount wraps decimals() in try/catch, but Solidity only catches reverts from the callee. If the token returns a full word above 255 (e.g. 300) or returns zero bytes without reverting, the ABI decoding of the uint8 return value fails in the faucet itself and that revert is not caught, so claim() reverts with empty revert data rather than UnsupportedDecimals(token).

      The spec only requires that such tokens revert, and no funds or cooldown state change, so this is a UX/error-message observation confined to that token's own pool. Non-blocking; noted because the frontend's 'display unsupported-token errors' step will see a bare revert for these tokens.

      Deploy an ERC-20 whose decimals() executes assembly { mstore(0, 300) return(0, 32) } (or return(0, 0)), mint 1e20 to the faucet, then call faucet.claim(token).

      Expected per README wording: revert UnsupportedDecimals(token).

      Actual: call fails with revert data 0x (empty); nextClaimAt(token, caller) stays 0 and the balance is unchanged.

      Verified in a scratch Foundry probe against the compiled src/TokenFaucet.sol.

    • infoDonor views expose tentative membership during the donate() token callback (read-only reentrancy)src/TokenFaucet.sol:48

      donate() marks the caller as listed and pushes to _donors before calling safeTransferFrom. A malicious token's transferFrom can therefore staticcall donorCount/donors and observe the donor already listed while donatedBy still reads 0. State-changing reentry is blocked by the shared guard, the tentative entry is rolled back if the transfer or the zero-receipt check fails, and only that token's own list is affected, so no payout or other pool depends on it.

      Already acknowledged in docs/REVIEW_HANDOFF.md. Non-blocking observation.

      Token T overrides transferFrom to record faucet.donorCount(T), faucet.donors(T,0,10)[0] and faucet.donatedBy(T, from) before performing the transfer.

      A (0xA1) approves and calls faucet.donate(T, 10).

      Observed inside the callback: donorCount = 1, donors[0] = 0xA1, donatedBy = 0.

      After the call: donorCount = 1, donatedBy = 10.

      Verified in a scratch Foundry probe.

    • infoA 1-unit partial claim consumes the full 24-hour cooldown (dust-sandwich griefing is possible by design)src/TokenFaucet.sol:71

      claim() stores nextClaimAt before transferring min(nominal, balance). Because the spec says a short pool pays whatever it holds and the README states a partial claim consumes the same cooldown, anyone can grief a claimer by leaving exactly 1 minor unit in the pool ahead of their transaction, or by draining the pool from many addresses.

      This is the requested behaviour for a Sepolia test faucet and is documented as not fair or valuable; it is recorded here so the frontend copy and reviewers are aware. Not a defect against the approved design.

      Pool for token S (6 decimals) is empty.

      B donates 1 unit.

      A calls claim(S): returns 1 and nextClaimAt(S, A) = block.timestamp + 86400.

      B then donates 1000e6.

      A calls claim(S) again: reverts CooldownActive.

      Separately, with 1000e6 in the pool, ten fresh addresses each call claim(S) and the pool balance reaches 0.

      Both verified in a scratch Foundry probe.
