The cryptocurrency market experienced a significant downturn following a flash crash on October 11, as revealed by data from DefiLlama. This decline was reflected in a sharp drop of open interest for perpetual contracts on decentralized exchanges (Perp DEX), which fell from $26 billion to below $14 billion. Notably, lending protocol fees reached an unprecedented peak of over $20 million last Friday, highlighting the volatility of the market. Meanwhile, decentralized exchanges (DEX) witnessed a record-breaking weekly trading volume exceeding $177 billion for the week. Additionally, total lending amounts within lending protocols fell below $50 billion for the first time since August, marking a significant shift in the financial landscape.
