Fee mismatch in FeeCollector::_initializeFeeTypes()

newspacexyz

Summary

The FeeCollector#_initializeFeeTypes() manually assigns fee distribution values without enforcing sum validation.

Vulnerability Details

  • The fee allocation does not always add up to BASIS_POINTS (10000).

  • The comment descriptions misrepresent actual allocated percentages.

  • This bypasses the validation check present in updateFeeType().

function _initializeFeeTypes() internal {
...
// Buy/Sell Swap Tax (2% total)
feeTypes[6] = FeeType({
veRAACShare: 500, // 0.5% //@audit Actually 5%
burnShare: 500, // 0.5%
repairShare: 1000, // 1.0%
treasuryShare: 0
});
// NFT Royalty Fees (2% total)
feeTypes[7] = FeeType({
veRAACShare: 500, // 0.5%
burnShare: 0,
repairShare: 1000, // 1.0%
treasuryShare: 500 // 0.5%
});
}

In feeTypes[7], the treasury share is set to 500, but _calculateDistribution() derives it as 8500 in _calculateDistribution(), creating an 8000 basis point discrepancy.

function _calculateDistribution(uint256 totalFees) internal view returns (uint256[4] memory shares) {
...
​
uint256 remainder = totalFees - (shares[0] + shares[1] + shares[2] + shares[3]);
@> if (remainder > 0) shares[3] += remainder;
}

In feeTypes[6], sum of shares is not equal to 10000, causing unintended fund allocations.

Impact

Incorrect Reward Calculations

Treasury may receive more or fewer funds than intended.

Modify _initializeFeeTypes() to use updateFeeType() instead of direct assignment.

Fee shares for fee type 6 and 7 inside FeeCollector do not total up to the expected 10000 basis points, this leads to update problems, moreover they are 10x the specifications
