Smart Contract Interest Rate Models

Smart contract interest rate models are the mathematical formulas encoded into lending protocols that determine interest rates based on supply and demand dynamics. These models typically use the utilization ratio as the main variable, with parameters like base rates, slope, and kink points to define the interest rate curve.

By automating this process, the protocols eliminate the need for manual rate setting and ensure that the market reaches equilibrium efficiently. These models must be carefully calibrated to balance the needs of lenders and borrowers while maintaining protocol stability.

They are the backbone of decentralized money markets and a key area of research in financial engineering.
