L-01 Fix: ReentrancyGuard on donateWithPermit

File: contracts/contracts/AbbababaScoreV1.sol

  • Added ReentrancyGuardUpgradeable import and inheritance
  • Added __ReentrancyGuard_init() to initialize() function
  • Added nonReentrant modifier to donateWithPermit()
  • Added reinitializeV5() for upgrade-safe ReentrancyGuard initialization
  • OZ v5 uses ERC-7201 namespaced storage, so adding a new parent is storage-safe
// Before
) external whenNotPaused {
 
// After
) external nonReentrant whenNotPaused {

L-03 Fix: MAX_ARBITRATORS Bound

File: contracts/contracts/AbbababaEscrowV1.sol

  • Added MAX_ARBITRATORS = 20 constant
  • Added _grantRole override to enforce cap before granting ARBITRATOR_ROLE
  • Prevents unbounded growth of arbitrator set that could cause gas limit issues in _getArbitrators() loop
uint256 public constant MAX_ARBITRATORS = 20;
 
function _grantRole(bytes32 role, address account) internal virtual override returns (bool) {
    if (role == ARBITRATOR_ROLE) {
        require(getRoleMemberCount(ARBITRATOR_ROLE) < MAX_ARBITRATORS, "Max arbitrators reached");
    }
    return super._grantRole(role, account);
}

Note on Test Count Change

Test count decreased from 287 to 262 due to the x402 pivot (commits fbb741a, 566ce98):

  • Removed: AbbababaStakingV1 tests (47 tests) — staking contract removed
  • Added: New x402-related tests for zeroed fees and updated registration flow
  • Net change: -25 tests (expected, not a regression)

Contract Versions

Fee Model (Post-x402 Pivot)

All on-chain percentage fees have been zeroed out. Revenue comes from x402 micropayments.

Fuzz Testing Status

⚠️

Echidna, Foundry fuzz, Medusa, Halmos, and Certora configs reference pre-x402 contracts (including staking). These need re-run after updating test harnesses for zeroed fees and removed staking logic.

Pre-Mainnet Checklist

  • M-01: Storage gaps added to all contracts
  • M-02: Pragma locked to 0.8.24
  • L-01: nonReentrant on donateWithPermit
  • L-03: MAX_ARBITRATORS bound (20)
  • L-02: Acknowledged (by design)
  • 262 Hardhat tests passing
  • Slither clean (no High/Medium)
  • Re-run fuzz suites post-x402
  • 95% mutation kill rate (pending fuzz re-run)
  • External audit (planned)

Next Steps

  1. Re-run Echidna/Foundry fuzz suites with updated contracts (zeroed fees, no staking)
  2. Update Medusa/Halmos/Certora configs for post-x402 contract state
  3. Deploy to Base Sepolia for testnet verification
  4. Target 95% mutation kill rate before mainnet
