Get Supply Rate

Get Supply Rate

This function returns the per second supply rate as the decimal representation of a percentage scaled up by 10 ^ 18. The formula for producing the supply rate is:

## If the Utilization is less than or equal to the Kink parameter

SupplyRate = supplyPerSecondInterestRateBase + supplyPerSecondInterestRateSlopeLow * utilization

## Else

SupplyRate = supplyPerSecondInterestRateBase + supplyPerSecondInterestRateSlopeLow * supplyKink + supplyPerSecondInterestRateSlopeHigh * (utilization - supplyKink)

To calculate the supply APR as a percentage, pass the current utilization to this function, and divide the result by 10 ^ 18 and multiply by the approximate number of seconds in one year and scale up by 100.

Seconds Per Year = 60 * 60 * 24 * 365
Utilization = getUtilization()
Supply Rate = getSupplyRate(Utilization)
Supply APR = Supply Rate / (10 ^ 18) * Seconds Per Year * 100

• utilization: The utilization at which to calculate the rate.

• RETURNS: The per second supply rate as the decimal representation of a percentage scaled up by 10 ^ 18. E.g. 317100000 indicates, roughly, a 1% APR.
