Gas Optimizations

x = x + y is cheaper than x += y

contracts\auth\AxelarAuthWeighted.sol:
   69          for (uint256 i = 0; i < weightsLength; ++i) {
   70:             totalWeight += newWeights[i];
   71          }

  104              // return if weight sum above threshold
  105:             weight += weights[operatorIndex];
  106              // weight needs to reach or surpass threshold

Inconsistent spacing in comments

Some lines use // x and some use //x. The instances below point out the usages that don't follow the majority, within each file

File: contracts\util\Proxy.sol
    45  // solhint-disable-next-line avoid-low-level-calls
    46  (bool success, ) = implementationAddress.delegatecall(
    47    //0x9ded06df is the setup selector.
    48    abi.encodeWithSelector(0x9ded06df, params)
);
