## Probability of Default Modeling

Probability of default modeling is the quantitative practice of estimating the likelihood that a borrower or counterparty will fail to meet their financial obligations within a specific timeframe. In the context of crypto lending protocols, this involves analyzing on-chain behavior, wallet history, and asset correlation to assign a risk profile to participants.

The model calculates the expected loss by combining the probability of default with the estimated recovery rate of the collateral. These models are crucial for determining appropriate interest rates and collateralization ratios for decentralized lending pools.

By accurately predicting default, protocols can better manage their risk reserves and protect liquidity providers from significant losses.
