In this project we are interested in understanding the systemic risk that arises from the fact that the technology facilitates the interoperability across the protocols, meaning that there are underlying connections and subsequent effects across different protocols. We map the interconnections among decentralized finance protocols using transactions among contracts and addresses, explore single-layer and multiplex network properties and quantify the financial exposure of the most critical nodes. This research is related to the recent paper (Saengchote and Castro, 2023).
