  Scoring the creditworthiness of accounts that interact with decentralized
financial (DeFi) protocols remains an important yet unsolved problem. In this
paper, we propose a credit scoring system for those accounts that have
interacted with the Aave v2 liquidity protocol. The key component of this
system is a tree-based binary classifier that predicts "position delinquency."
To the community, we provide our method, results, and the (abridged) dataset on
which this system is built.
