Using balanceOf Instead of Voting Power

aariiif

Summary

These contracts (BaseGauge, GaugeController) use veToken.balanceOf() instead of getVotingPower(). This ignores lock expiration decay, leading to incorrect boost and voting power calculations.

Vulnerability Details

The use of balanceOf() instead of getVotingPower() creates significant calculation discrepancies in the protocol.

In BaseGauge.sol#_applyBoost

function _applyBoost(address account, uint256 baseWeight) internal view virtual returns (uint256) {
IERC20 veToken = IERC20(IGaugeController(controller).veRAACToken());
uint256 veBalance = veToken.balanceOf(account); // Should use getVotingPower
​

In GaugeController.sol#vote

function vote(address gauge, uint256 weight) external override whenNotPaused {
uint256 votingPower = veRAACToken.balanceOf(msg.sender); // Should use getVotingPower
​

Economic Impact:

  • Boost calculations provide wrong multipliers

  • Reward distributions become inequitable

  • Incentive mechanisms fail to reward lock duration

  • Protocol revenue sharing becomes imbalanced

Impact

Users have no incentive to lock longer

Recommendations

Replace the instances of balanceOf with getVotingPower(account, block.timestamp) to reflect actual voting power.

// In BaseGauge.sol
function _applyBoost(address account, uint256 baseWeight) internal view returns (uint256) {
uint256 votingPower = veToken.getVotingPower(account, block.timestamp);
uint256 totalVotingPower = veToken.getTotalVotingPower();
return calculateBoost(votingPower, totalVotingPower, baseWeight);
}
​
// In GaugeController.sol
function vote(address gauge, uint256 weight) external whenNotPaused {
uint256 votingPower = veToken.getVotingPower(msg.sender, block.timestamp);
_updateGaugeWeight(gauge, weight, votingPower);
}
​
// In BoostController.sol
function calculateBoost(address user, address pool, uint256 amount) external view returns (uint256) {
uint256 votingPower = veToken.getVotingPower(user, block.timestamp);
return _calculateBoost(votingPower, amount);
}

BaseGauge::_applyBoost, GaugeController::vote, BoostController::calculateBoost use balanceOf() instead of getVotingPower() for vote-escrow tokens, negating time-decay mechanism
