Vulnerability details

Impact

As i is an uint, it is already initialized to 0. uint i = 0 reassings the 0 to i which wastes gas.

Proof of Concept

AirdropDistributionMock.sol:97: for (uint i = 0; i < airdropArray.length; i++) {
PublicSaleBatchWithdraw.sol:29: for (uint i = 0; i < arrayDays.length; i++) {
PublicSaleBatchWithdraw.sol:36: for (uint i = 0; i < length; i++) {
AirdropDistribution.sol:507: for (uint i = 0; i < airdropArray.length; i++) {

Tools Used

Manual testing

Recommended Mitigation Steps

Do not initialize i variable to 0 -> for (uint i; i < airdropArray.length; i++) {
