Chainlink said the new feeds include more than just prices. They also deliver bid and ask levels, trading volume, market status indicators, and freshness signals, which help reduce risks during volatile or low-liquidity periods.
Use in DeFi and Tokenized Markets
The data streams are designed to support on-chain products such as stock-linked perpetual contracts, prediction markets, synthetic equities, lending platforms, and other tokenized asset products.
