Overview

the lending pool contract contains functions to set the protocol fees which can be called by the owner.

This function enables the owner to define the fee percentage that should be charged on lending transactions.

However, there are no implementations in the contract where users are actually charged fees.

For example, in functions like repay, which handles debt repayment, no fee deductions take place:

When the protocol is deployed the initial protocol fees is set to 0. This means that even if fee logic was present, no fees would be collected until the owner sets a non-zero fee rate.
However, even after setting a fee rate, the contract lacks the logic to actually charge it.

given that the protocol intends to charge fees the contract should have implementations that enable fee calculations that should be charged later when the fee rates are set

Impact

Loss to the protocol

Recommendation

Implement fee deducting in areas where protocol needs fees to be charged.
