Interest Rate Model

APY Function

Borrow APY

= [1 + Base + Multiplier * min(UtilizationRate, Kink) + max(JumpMultiplier * UtilizationRate - Kink, 0)] ^ 2102400 - 1

Supply APY

= Distribute (Interest Paid by Borrowers Per Block - Reserve) to all suppliers, and convert it into APY

= Distribute [(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] * Total Borrow * (1 - Reserve Factor) to all suppliers, and convert it into APY

= {[(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] * Total Borrow * (1 - Reserve Factor) / Total Supply}, and convert it into APY

= {1 + [(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] * Total Borrow * (1 - Reserve Factor) / Total Supply} ^ BlocksPerYear - 1

= {1+[(1+Borrow APY)^(1/BlocksPerYear)-1]*(1-Reserve Factor)*Utilization Rate}^BlocksPerYear-1

BlocksPerYear = 2,102,400 (15 sec per block)
