Summary

Protocol will not work with erc20s that revert on 0 amount transfer.

Vulnerability Details

Some tokens (e.g. LEND) revert when transferring a zero value amount. Even if the areListsValid function checks whether there are 0 amounts, the airdropERC20 does not. This means that if 0 amounts get into the amounts array, the function will revert in the case of using such tokens.

Impact

Function could revert due to 0 amount transfer.
