Risky Business? Deep Dives into DeFi

Studying the emerging blockchain financial ecosystem
From "DeFi Survival Analysis: Insights into Risks and User Behaviors" (March 2022)

Decentralized Finance (DeFi) is an emerging new financial ecosystem built on the back of blockchain technology. With over $2 trillion locked in cryptocurrencies and the rapid adoption of new DeFi products by retail users and institutions, it's natural to wonder how this new financial ecosystem will disrupt the traditional financial sector. We seek to investigate current patterns of usage in DeFi lending protocols, and quantify risk and user behaviors across various protocols. Our strategy is to exploit powerful AI models and technology developed for transaction data such as those arising in health and commerce. For example, we can utilize temporal clustering to characterize different types of users and then use these in a dashboard to understand how usage of lending protocols changes over time.

We are developing these methods to analyze any lending protocol in the DeFi sphere. As we develop these methods, we are testing them on data that we've collected from the AAVEv2 protocol, which is one of the largest lending protocols in DeFi. This data has been collected using and API provided by The Graph, which compiles data directly from AAVE. We welcome suggestions and collaborations to further extend our analyses to address compelling DeFi questions.

Liquidations, the DeFi equivalent of defaults on loans, can help us learn about risky behavior in lending protocols. We are using statistical methods and advanced AI to learn about risk in DeFi, starting from liquidations in lending protocols. Can we identify which conditions in the market create risk as a whole? Can we effectively use AI to learn what behavioral patterns are good predictors that a user will eventually liquidate? Which users are having the biggest influence on liquidation? We explore these questions and more in our most recent paper, "DeFi Survival Analysis: Insights into Risks and User Behavior," recently submitted to MARBLE 2022: The 3rd International Conference on Mathematical Research for Blockchain Economy (July 2022)
