WOH-03C: Loop Iterator Optimizations

Type	Severity	Location
Gas Optimization		WiseOracleHub.sol:L185, L234, L271

Description:

The linked for loops increment / decrement their iterator "safely" due to Solidity's built - in safe arithmetics (post-0.8.X).

Example:

for (uint8 i = 0; i < _tokenAddresses.length; ++i) {

Recommendation:

We advise the increment / decrement operations to be performed in an unchecked code block as the last statement within each for loop to optimize their execution cost.
