What is the total value locked in DeFi lending?

Could you please elaborate on the current state of the decentralized finance (DeFi) lending market? Specifically, I'm interested in knowing the total value locked (TVL) in DeFi lending platforms. How has this figure evolved over time? Are there any notable trends or shifts in the market that have contributed to the current TVL? Additionally, what are some of the key factors that investors should consider when evaluating the potential risks and rewards associated with DeFi lending?
