[TEMP CHECK] Onboard STG to Ethereum Aave v3

Overview

Following the successful Snapshot for this [TEMP-CHECK], we have conducted an analysis and provide risk parameter recommendations for the initial listing of STG.

Liquidity and Market Cap

When analyzing market cap and trading volumes of assets for listing, we look at data from the past 180 days. The average market cap of STG over the past 180 days was ~$120M, and the average daily trading volume was ~$20M (CeFi & DeFi).

Liquidation Threshold

Analyzing STG price volatility over the past, we observed daily annualized volatility of 102.47% and 30-day annualized volatility of 46.09%. While we could propose a higher LT based on volatility considerations, we recommend a more conservative launch with a 40% LT due to the asset’s relatively low market cap.

We support listing STG as borrowable under reasonable limits of supply cap, as we do not observe a significant risk to the protocol by allowing to borrow the asset.

Debt Ceiling

Following Chaos Labs’ Isolation Mode Methodology, we recommend an initial debt ceiling of $3M. Under the methodology for Isolation Mode, we consider two levels of probabilities for extreme price drops - Medium-High and High. We estimate the probability of an extreme price drop for STG as High. Given this debt ceiling, we do not identify a profitable attack vector under the current liquidity levels.

Supply Cap, Borrow Cap, and Liquidation Bonus

Following Chaos Labs’ approach to initial supply caps, we propose setting the Supply Cap at 2x the liquidity available under the Liquidation Penalty price impact.

Given the concentrated liquidity of STG we recommend a 10% Liquidation Bonus and support the supply cap of 10,000,000 STG, in the original post. We recommend setting the initial borrow cap at 5.5M STG.
