Approved workflow

Build a simple crypto game with its own token, deploy it on Sepolia through the network's project factory, publish the source on GitHub, and publish a public website to play it on IPFS. The game is High Roll: two players stake the same amount of the game's token, each commits a hidden dice roll from 1 to 6 with a salt, both reveal within a 24-hour window, the higher roll takes the pot, a tie refunds both, a single reveal before the deadline wins by forfeit, and no reveals lets either player cancel for a refund. No fee, no owner, no admin, no upgradeability. Independent review before deployment and again on the finished site, then a website where a visitor connects a wallet, approves the token, opens or joins a game, commits and reveals a roll, and reads the rules and the risks.

The network has about fifteen agents online, so two independent reviews are wanted: one on the contracts and manifest before deployment, one final review after the site. Follow the evm-project-launch guidance: a fixed-supply ERC-20 named High Roll with symbol ROLL, 18 decimals, zero-argument constructor minting the whole supply to its deployer, and one game contract whose only constructor argument is the token address passed as $token. Contributors never broadcast and never receive keys; the admitted release goes through the deployer on Sepolia, chain 11155111. Source publication to GitHub and website hosting on IPFS are both authorized. The website must load dist/imd-deployment.json as its runtime deployment configuration and its ABIs from there, use React, Vite, TypeScript, RainbowKit, wagmi and viem, keep its source under web/ and export a relative-base static build to dist/.

Build and independently review High Roll, a two-player commit-reveal dice game played for its own fixed-supply token, for a Sepolia project launch, then a public website to play it. Token: High Roll (ROLL), 18 decimals, zero-argument constructor minting the whole supply to its deployer, no mint backdoor. Game contract HighRoll: constructor takes only the token address ($token); open a game by staking ROLL (transferFrom) and committing keccak256(roll, salt) with roll 1 to 6; a second player joins with the same stake and commit; both reveal within 24 hours; higher roll wins the pot, tie refunds both, one reveal before the deadline wins by forfeit, no reveals lets either player cancel for a refund. No fee, owner, admin, upgradeability or external calls beyond the token; checks-effects-interactions; events for opened, joined, revealed, settled, cancelled. Thorough Foundry tests for every outcome, forfeit, refund, invalid commits, wrong stakes, reentrancy through a malicious token and token permissions. The manifest names the token and the game with the $token argument. Independent adversarial review of the contracts and manifest before deployment. Then the website: connect a wallet, approve ROLL, open or join a game, commit and reveal, see open and settled games and the rules and risks; loads dist/imd-deployment.json and its ABIs; React, Vite, TypeScript, RainbowKit, wagmi, viem; source in web/, static export in dist/. A final independent review of the whole delivery.

Instructions for this stage

WORKFLOW CONTRACT STAGE CONTEXT: the stage produces implemented and tested contracts, ABI documentation and an independently reviewed launch.json. Each assignment contributes only within its own role and write scope. Source-producing assignments own implementation, tests and ABI exports at docs/abi/.json where their scope permits.

The generated manifest assignment writes only launch.json. Review assignments inspect accepted source and manifest and return findings without editing files; they do not implement contracts or generate ABI files. Use the supplied canonical manifest guidance: policy and signed artifact linkage belong to services, while concrete source, constructor, policy or authorization conflicts remain review findings.

Services publish source, attest, admit and deploy after this stage, then start the frontend. Read .imd/reads/workflow.md for the complete approved requirements and apply them to your assigned contribution; later service outcomes are not prerequisites of this assignment.

  • lowA valid join is rejected when both players independently use the same commitmentsrc/HighRoll.sol:90

    The approved rules require each player to commit a roll from 1 to 6 with a salt, but do not require the two commitment hashes to differ. joinGame rejects commitment == game.commitment1, so two players who independently choose identical roll and salt cannot play even though both can later prove their commitments. The test test_joinRejectsWrongStakeSelfZeroCopiedAndDuplicate codifies this extra restriction instead of testing the specified valid state.

    Let salt = bytes32(uint256(123)) and commitment = HighRoll.commitmentHash(4, salt).

    Alice calls openGame(10 ether, commitment), then Bob calls joinGame(0, 10 ether, commitment).

    Expected: Bob's equal stake is escrowed and game 0 becomes Active; both can reveal (4, salt) and receive tie refunds.

    Actual: Bob's join reverts with InvalidCommitment at line 90 and the game remains Open.
