What is $R_{reserve}$

$$R_{reserve}$ refers to a portion extracted from the loan interest rate, retained as platform earnings for the purpose of platform maintenance, risk reserves, development, or other operational needs.

$R_{reserve} ​ =R_b ​\times (1-U)$

• $R_b$​: Borrowing interest rate.

• $U$: Utilization rate, which is the ratio of total borrowing to total asset supply.

Liquidation Fee

When a user's position triggers the liquidation line, the platform will charge a 5% liquidation fee on the liquidation amount. This fee covers risk management and administrative efforts for handling liquidation assets, ensuring platform stability. After the liquidation is completed, any remaining balance of the liquidation fee will be refunded.

$\text{liquidation fee}=\text{Liquidated assets value × 5\%}$

Borrow Fee

The borrow fee is a one-time fee charged when a user borrows funds from the Portal Finance platform. This fee is automatically deducted at the time of borrowing. $\text{Borrow\ Fee}=\text{Total Loan Amount}\times \text{Fee Rate}$
