The decentralized finance (DeFi) sector has experienced a significant contraction, with only four protocols maintaining a total value locked (TVL) above $10 billion, according to DeFiLlama data. The protocols are Aave, Lido, EigenLayer, and Binance staked ETH. This development follows a recent market downturn and the withdrawal of some positions, leading to a more than 10% decline in TVL for leading DeFi protocols over the past month.
