Chainlink Data Streams Go Live on Sei Network

September 6, 2025 – Chainlink Data Streams are now live on Sei Network, marking a major milestone for both ecosystems. The Sei Development Foundation and Chainlink Labs confirmed the integration on September 5, positioning Chainlink as the preferred oracle infrastructure for Sei’s $1.2 billion DeFi ecosystem.

The launch delivers institutional-grade, ultra-low-latency data, including U.S. government macroeconomic statistics, directly to Sei’s high-performance Layer 1, enabling faster, more secure digital asset markets.

Why It Matters

The integration arrives as institutional adoption of blockchain accelerates. Chainlink Data Streams, which already secure trillions in onchain value, will now supply Sei with sub-second data delivery, liquidity-weighted bid-ask spreads, and reliable proof-of-reserve functionality.

Adding weight to the rollout, Chainlink’s recent partnership with the U.S. Department of Commerce means official economic data, such as GDP and PCE Price Index, will flow directly into Sei’s onchain markets. This convergence of government-verified data with blockchain infrastructure is seen as a turning point for financial applications.

What the Leaders Said

Justin Barlow, Executive Director at the Sei Development Foundation, called Data Streams the “obvious choice” for the ecosystem, citing its ultra-low-latency delivery and battle-tested infrastructure.
