Submission Details
Severity:
Wrong calculation of `claimantCut` in `Pot::closePot`, players who claimed in time will receive smaller amount than expected.
Description:
In document, when 90 days passed, the manager takes a cut of the remaining pool and the remainder is distributed equally to those who claimed in time (not for all players).
But this function count all the players in players array to calculate the amount to be sent, regardless of whether they claimed in time or not.
function closePot() external onlyOwner {
if (block.timestamp - i_deployedAt < 90 days) {
revert Pot__StillOpenForClaim();
}
if (remainingRewards > 0) {
uint256 managerCut = remainingRewards / managerCutPercent;
i_token.transfer(msg.sender, managerCut);
@> uint256 claimantCut = (remainingRewards - managerCut) / i_players.length;
for (uint256 i = 0; i < claimants.length; i++) {
_transferReward(claimants[i], claimantCut);
}
}
}
Impact:
All players will receive bonus and players who claimed in time will receive smaller amount than expected.
Tools Used:
Manual review
Recommendations:
replace i_players.length by claimants.length.
function closePot() external onlyOwner {
if (block.timestamp - i_deployedAt < 90 days) {
revert Pot__StillOpenForClaim();
}
if (remainingRewards > 0) {
uint256 managerCut = remainingRewards / managerCutPercent;
i_token.transfer(msg.sender, managerCut);
- uint256 claimantCut = (remainingRewards - managerCut) / i_players.length;
+ uint256 claimantCut = (remainingRewards - managerCut) / claimants.length;
for (uint256 i = 0; i < claimants.length; i++) {
_transferReward(claimants[i], claimantCut);
}
}
}
