TSender

Summary

The TSender contract performs redundant length checks in the airdropERC20 function. This redundancy results in unnecessary gas consumption.

Vulnerability Details

The contract contains two separate checks for the equality of the lengths of recipients and amounts arrays: one in TSender::areListsValid and another in TSender::airdropERC20. This duplication is not needed and can be optimized to reduce gas usage.

Impact

The redundant checks lead to increased gas costs.

Recommendations

Remove the length check from the TSender::airdropERC20 function and rely on the TSender::areListsValid function to perform this validation.
