According to online reports, Chainlink officially released the DeFi Yield Index (CDY Index), which is used to aggregate market-wide DeFi lending rates. The index adopts the Chainlink standard and combines Space and Time's blockchain index and database technology to ensure the accuracy, robustness and market representativeness of the data, and provides support for the discovery of on-chain lending opportunities and the improvement of capital efficiency. According to reports, the CDY Index focuses on the most liquid markets such as USDC, USDT, WBTC and WETH. It aims to help traditional financial institutions, DeFi protocols and ordinary users obtain on-chain revenue information more transparently and efficiently, and improve market liquidity and investment feasibility.
