TL;DR
- Sei has integrated Chainlink Data Streams as its oracle infrastructure, bringing in secure, low-latency market data.
- The solution delivers real-time prices with sub-second latency, liquidity-weighted spreads, and enriched reports that strengthen risk management.
- Chainlink will introduce official U.S. macroeconomic data onchain.
Chainlink and the Sei Development Foundation announced the integration of Data Streams as the preferred oracle infrastructure for the Sei Network.
The agreement introduces a low-latency data system designed to support real-time financial applications with accurate and verifiable pricing, enhancing Sei’s role as a fast-settlement blockchain focused on decentralized finance and high-performance services.
Data Streams provides a sub-second model for market information delivery, built on Chainlink’s infrastructure that has already secured over $25 trillion in onchain transaction volume. Beyond reliable price feeds, the system includes advanced features such as liquidity-weighted bid-ask spreads and more detailed reports that incorporate corporate actions and ETF data. This equips financial applications built on Sei with more sophisticated tools for risk management and pricing.
The integration comes as institutional adoption of blockchain accelerates. Chainlink recently entered into a collaboration with the U.S. Department of Commerce to bring onchain data from the Bureau of Economic Analysis, including real GDP, the PCE Price Index, and domestic consumption metrics.
Sei Will Be Able to Develop Institutional-Grade Applications
Direct access to official data introduces into Sei a type of input that was previously out of reach for onchain markets, enabling the creation of financial products that combine crypto liquidity with traditional macroeconomic variables.
Executives from both organizations emphasized that the combination of security and transparency from both networks creates an environment suitable for institutional-scale DeFi applications. Beyond lending, trading, and derivatives, the integration also aims to support expansion into new areas such as gaming and consumer apps that demand high data accuracy.
Sei has established itself as a layer-1 blockchain with EVM compatibility, having processed billions of transactions across more than 60 million users, which places it among the most widely used networks
