# Can a decentralized reputation system built on Eigenlayer be a good alibi for creditworthiness? ## Overview This research presents a comprehensive analysis of DeFi wallet creditworthiness using zscore metrics, based on a study of 4,410 liquidated wallet addresses on Aave in last 48 hours (02-02-2025 to 03-02-2025). The findings demonstrate how zscore can serve as a reliable predictor for liquidation risk assessment in DeFi lending. ## Dataset - **Total Sample Size**: 5,138 liquidated addresses - **Analyzed Wallets**: 4,410 (85.8% coverage) - **Score Range**: 0-600 📊 Liquidation Analysis Report ═════════════════════════════════════════════ 📈 Total liquidated addresses: 5138 🎯 Found zScores for 4410 wallets 💽 Link to zScore data of 4410 wallets ([Click here](https://drive.google.com/drive/folders/1jMDwv25J6VsDdN4JozKpvdfl9Vk_EZb5?usp=sharing)) 📊 ZScore Distribution ![Screenshot 2025-02-03 at 6.13.09 PM](https://hackmd.io/_uploads/rJcb5EAdJg.png) ## Key Findings ### Score Distribution Analysis The analysis revealed several critical risk zones in the zscore distribution: #### Primary Risk Zone (190-200) - Highest concentration: 28.87% of all liquidations - Represents critical risk threshold #### Secondary Risk Clusters - 330-340 range: 10.02% of liquidations - 120-130 range: 8.62% of liquidations - 220-250 range: Combined 10.50% of liquidations ### Statistical Metrics - **Average ZScore**: 245.92 - **Median ZScore**: 205.32 The right-skewed distribution indicates that while most liquidations occur in lower-scoring wallets, high-scoring wallets are not immune to liquidation risks. ## Risk Assessment Framework | Risk Level | Score Range | % of Liquidations | Implication | |-----------------|------------|-----------------|--------------| | **Very High** | <200 | ~45% | Needs max collateralization | | **High** | 200–300 | ~30% | Higher liquidation probability | | **Moderate** | 300–400 | ~20% | Standard collateralization | | **Lower Risk** | 400+ | ~5% | Favorable lending terms | ## Summary #### **1. Dataset Overview** - **Total liquidated addresses**: 5,138 - **Analyzed wallets**: 4,410 (**85.8% coverage**) - **zScore range**: 0–600 --- #### **2. Key Risk Zones** - **Primary Risk Zone (190–200)**: - **28.87% of liquidations** (1,273 wallets), the highest concentration. - **Secondary Risk Clusters**: - **330–340**: 10.02% (442 wallets). - **120–130**: 8.62% (380 wallets). - **220–250**: Combined **13.61%** (220–230: 5.42%, 230–240: 3.11%, 240–250: 5.08%). - **Notable Outliers**: - **550–560**: 3.33% (147 wallets) – significant for a "lower risk" bracket. - **10–20**: 2.45% (108 wallets) – surprisingly high for the lowest zScore range. --- #### **3. Statistical Insights** - **Average zScore**: 245.92 - **Median zScore**: 205.32 - **Distribution**: Right-skewed – **~73% of liquidations** occurred in zScores **<300**, but even high scores (e.g., 550–560) saw **3.33% liquidations**. --- #### **4. Risk Categories & Liquidation Probabilities** - **Very High Risk (<200)**: - **~45% of liquidations** (1,273 in 190–200 alone). - Requires maximum collateralization. - **High Risk (200–300)**: - **~30% of liquidations**, including: - 220–250: 13.61% - 280–290: 1.86% - **Moderate Risk (300–400)**: - **~20% of liquidations**, dominated by **330–340** (10.02%). - **Lower Risk (400+)**: - **~5.06% of liquidations**, with notable clusters: - 550–560: 3.33% - 360–370: 5.06% --- #### **5. Critical Observations** - **Volatility in Mid-Range Scores**: - Scores like **360–370** (5.06%) and **550–560** (3.33%) defy the "lower risk" expectation, suggesting collateral or debt volatility. - **Low-Score Vulnerability**: - Scores **<130** (e.g., 10–20, 120–130) still account for **~11% of liquidations**, indicating poor risk management. --- #### **6. Conclusion** - **zScore** is a **strong predictor** of liquidation risk, especially for scores **<200** (~45% of liquidations). - Even "lower risk" wallets (400+) are **not immune** (5% liquidations), emphasizing the need for dynamic risk models. - Protocol designers should flag **190–200**, **330–340**, and **220–250** as priority monitoring zones. The zscore metric proves to be a reliable predictor of liquidation risk in DeFi lending. Integration of these insights into risk assessment models can enhance protection for both lenders and borrowers while maintaining system stability.
