Interest Rate Curve Validation
Interest Rate Curve Validation is the process of testing the mathematical models that govern borrowing and lending rates to ensure they promote market equilibrium. These curves are designed to incentivize liquidity when it is scarce and discourage over-borrowing when the pool is nearly empty.
Validation involves checking that the interest rate logic reacts appropriately to changes in utilization rates and that it does not create incentives for manipulative borrowing behavior. It ensures that the protocol's revenue generation remains sustainable while providing competitive rates to users.
By stress-testing the curve against various market cycles, developers can verify that the model remains efficient and stable. This validation is critical for the long-term health of lending protocols, as it directly impacts user adoption and protocol profitability.
