## Probability of Default

Probability of Default is a quantitative estimate of the likelihood that a borrower or counterparty will fail to meet their contractual financial obligations over a specific time horizon. In the decentralized finance ecosystem, this is often modeled using on-chain data, such as a user's historical repayment behavior, wallet age, and current leverage ratios.

Unlike traditional finance, where credit scores rely on centralized bureaus, crypto protocols derive this probability from algorithmic analysis of address behavior and collateral quality. High probability indicates a significant risk of insolvency, prompting the protocol to demand higher collateral or increase interest rates to compensate for the added risk.

This metric is essential for dynamic risk pricing and automated credit assessment. It helps in maintaining the health of the lending pool by filtering out or penalizing high-risk participants.

When the probability increases across the network, it often signals systemic stress or a market-wide downturn. Accurately predicting this allows for proactive risk mitigation.
