Optimization suggestions


1- Loop on the dynamic variable (low severity).

If the user gets more parallel deposits his withdrawal transaction fee will cost more transaction fees because the loop on the dynamic variable is used in the ‘withdraw’ function.

In case of the GAS limit of exceeding the size of transaction withdraw is not possible.


This comment is relevant only if a user creates an excessive number of parallel deposits (more than 100).
