### Borrowing Interest Rate Model in NFT Pool

**The Interest Rate Model is:**

**Borrow APR:**&#x20;

Optimal Utilization Rate: Uk Base rate: R0 The interest rate corresponding to the optimal capital utilization rate: Rk The interest rate when the capital utilization is 100% minus R0 and Rk: R100 Utilization rate: U Reserve Factor: r

* If U\<Uk, Borrow APR=R0​+U/Uk​∗Rk​​​&#x20;
* If U≥Uk, Borrow APR=R0​+Rk​+(U−Uk​)/(1−Uk​)∗R100​​​

**Parameter Settings:**

R0=3%

Rk=15%

R100=100%

Uk=60%

r=10%

**Example：**

When U=50%, Borrow APR=3%+50%/60%\*15%=15.5%

When U=80%, Borrow APR=3%+15%+（80%-60%）/(1-60%)\*100%=68%
