Rigor Protocol contest - tofunmi's results

Use a more efficient loops for all operations to save a lot of gas use unchecked{ ++i; } to increment i on each iteration like so

Affected lines of inefficient loops for gas savings

  • do this instead

   for (uint256 i = 0; i < _communities[_communityID].memberCount;) {
      unchecked{
       ++i;
