Chainlink is enhancing the DeFi ecosystem by expanding its data offerings beyond price feeds to include asset volatility data, addressing the growing demand for secure external data sources. Realized and implied volatility metrics are now available to DeFi developers through Chainlink's decentralized oracle networks, facilitating the creation of advanced financial products and risk management strategies. Realized volatility, based on historical data, is delivered via Chainlink Realized Volatility Data Feeds, while implied volatility, a predictive measure, is accessible through Chainlink Functions, allowing developers to tailor data consumption to their specific needs. These developments enable DeFi applications to dynamically adjust risk parameters, improve capital efficiency, and manage portfolios effectively, ultimately contributing to the maturity and utility of the DeFi ecosystem.
