New Dataset: DeXposure - Inter-protocol Credit Exposure in Decentralized Finance (2020-2025)

[Wenbin Wu]

Dear ICAIF community,

I wanted to share a new dataset and paper that might be useful for those working on financial networks and decentralized finance.

We've built DeXposure, the first large-scale dataset mapping how DeFi protocols are financially exposed to each other. It's quite comprehensive - 43.7 million entries covering 4,300 protocols and 24,000 tokens from 2020 to 2025.

The paper introduces a measure we call "value-linked credit exposure" and tracks how the DeFi market structure has evolved over time. We also provide benchmarks for graph clustering, VAR analysis, and temporal graph neural networks, along with an analysis comparing how shocks propagated differently during Terra versus FTX.

Everything is publicly available - the paper is on ArXiv, and both code and data are released.

Paper: https://arxiv.org/abs/2511.22314 Code: https://github.com/dthinkr/DeXposure Data: https://www.kaggle.com/datasets/spicycorn/defi-network-dataset-2020-2025

Happy to discuss or answer any questions. Hope some of you find it useful.

Best,
