Submission Details
Impact:
Likelihood:
[L-1] Incorrect payouts if there's no teachers at `LevelOne.sol` contract in `listOfTeachers` array
Description:
The graduateAndUpgrade() logic assumes listOfTeachers.length> 0 , where if its zero, the payout math could fail silently or return nothing.
Impact:
If the number of teachers are zero, the logic will break and leads to math error for the contract
Remediation:
Consider adding the following code inside LevelOne::graduateAndUpgrade()
uint256 totalTeachers = listOfTeachers.length;
if(totalTeachers == 0) {
revert HH__NoTeachersRegistered();
}
