The Sei Development Foundation and Chainlink have announced the deployment of Chainlink Data Streams as the preferred oracle infrastructure for the Sei Network, delivering a secure, reliable and verifiable on-chain data standard to the ecosystem.

The integration positions Chainlink Data Streams as a low-latency solution capable of delivering high-frequency, premium market data with features such as liquidity-weighted bid-ask spreads and sub-second execution speeds, while preserving transparency and decentralization.

Under the collaboration, Chainlink will relay U.S. Department of Commerce BEA datasets—including real GDP, the PCE price index and internal purchase indicators—onto the Sei Network, providing institutional-grade macroeconomic inputs for on-chain markets and compliant DeFi applications.
