Modeling the risks within the protocol Aave, with an application to portfolio allocation
Researchers present a detailed analysis of liquidation risk in Aave, a decentralized finance (DeFi) lending platform. They introduce a mathematical model and the PCS (Proportional Collateral Seizure) strategy, which ensures fair collateral seizure across multiple assets. The study provides formulas for liquidation probability and expected liquidation time, showing that ignoring liquidation risk, as in traditional portfolio theory, can lead to risky strategies. Liquidations can occur within minutes, and most users treat them as routine events.
What it examines
This paper models the risks of liquidation in Aave, a decentralized lending and borrowing protocol. It uses mathematical and stochastic methods to analyze how asset price changes can trigger liquidations, and applies these models to optimize cryptocurrency portfolios, aiming to improve risk management in DeFi investing.
What it concludes
The study provides efficient ways to estimate liquidation risk and portfolio performance in Aave, helping investors make safer decisions. Its methods can be used for risk assessment, portfolio optimization, and stress testing in DeFi. Future work may include partial liquidations, discrete price updates, and user-driven interest rates.
Evidence objects
Researchers unveil a pioneering quantitative framework for assessing liquidation risk in Aave, introducing efficient stochastic models and closed-form formulas for key indicators like liquidation probability and expected liquidation time in DeFi portfolios.

Findings reveal that ignoring liquidation risk, as in traditional Markowitz theory, leads to riskier DeFi investments; liquidations can occur within minutes, and most users treat them as routine, unlike in traditional finance.

This paper uniquely formalizes Aaves lending, borrowing, and liquidation mechanisms using its open-source code, introducing a mathematically rigorous, stochastic model for liquidation risk. Unlike prior single-collateral studies, it addresses multi-asset cases, offering fresh insights for DeFi, quantitative finance, and portfolio optimization, making it compelling and highly relevant.
