Severity:
Protocol will not work with erc20s that revert on 0 amount transfer
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.
Tools Used
Manual review
Recommendations
Using the areListsValid function in airdropERC20.
