Foundry DeFi Stablecoin CodeHawks Audit Contest

Summary

Vulnerability Details

The unchecked keyword is new in solidity version 0.8.0, so this only applies to that version or higher, which these instances are.
Gas savings: roughly speaking this can save 30-40 gas per loop iteration. For lengthy loops, this can be significant!

More detail see this.

There are 2 instances of this issue:

• i ++ should be used unchecked{++i}/unchecked{i++}.

• i ++ should be used unchecked{++i}/unchecked{i++}.

Impact

Tools Used

Recommendations

Using unchecked{++i}/unchecked{i++} replace ++i/i++ in loop.
