In this study, we investigate the operational mechanisms and monetary flows of two major yield aggregators, Yearn Finance and Cian, over the period from May 4, 2024 to May 3, 2025. Our supporting conceptual framework decomposes yield aggregator operations into user investment and strategy management cycles. Using a network approach for 2,459 Yearn and 921 Cian transactions, we trace protocol interactions and capital flows across the ecosystem.
