Chainlink has released a new product called Data Streams, which brings live pricing information for major U.S. equities and ETFs directly onto 37 different blockchain networks. The service is now live and provides real-time data for popular stocks and funds, including SPY, QQQ, NVDA, AAPL, and MSFT.
How It Works and Why It’s Important
Data Streams uses Chainlink’s decentralized oracle networks to securely aggregate and deliver real-time data from various sources. Each data point is timestamped, ensuring that developers can verify the freshness of the information and automatically pause trading when markets close.
This new capability is expected to be a major catalyst for the tokenized real-world assets (RWA) market, which is projected to grow to $30 trillion by 2030. The live data enables the creation of sophisticated on-chain financial products, such as:
- Tokenized stock trading
- Perpetual futures
- Lending and borrowing platforms
- Synthetic ETFs
According to Chainlink’s Chief Business Officer, Johann Eid, this product is a “significant leap forward” in connecting traditional finance with blockchain technology. Major DeFi protocols, including GMX and Kamino Finance, have already integrated Data Streams, highlighting its immediate utility and potential to build a more advanced and secure on-chain financial system.
