RECOMMENDATIONS (very low severity): 0

Hint and tips to improve contract functionality and trustworthiness.


Optimization suggestions

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

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

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


This comment is relevant only if a user creates an excessive number of parallel deposits (more than 200).
