🔵On-chain views

This section describes on-chain (old-style) views to provide math of utilization, borrow and supply rate.

Let utilisationRate is

$$U = \dfrac{borrows}{cash+borrows-reserves}$$

getUtilizationRate

and

$$kink = U^*$$

then borrowRate is

$$B = \begin{cases} baseRate + U * multiplier & \text{if } U \leqslant U^*\\ baseRate + U^* * multiplier + (U - U^*) * jumpMultiplier & \text{if } U > U^*\\ \end{cases}$$

getBorrowRate

finally, supplyRate is

$$S=B*U*(1-reserveFactor)$$

getSupplyRate
