Summary

The reward to be distributed per voter in the event of a successfull proposal is wrong.

Vulnerability Details

At line 192:

uint256 rewardPerVoter = totalRewards / totalVotes;

This is wrong. It should be:

uint256 rewardPerVoter = totalRewards / totalVotesFor;

instead

Impact

Medium, potential rewards for the upVoters are less, disincentivising users to vote.

Tools Used

Just reading the code.

Recommendations

Swap line 192 with the code:

uint256 rewardPerVoter = totalRewards / totalVotesFor;
