Quick Breakdown:
- Chainlink Data Streams integrated on Sei as the network’s preferred oracle, delivering sub-second market data for DeFi and tokenized assets.
- The partnership strengthens Sei’s role in institutional-grade crypto adoption with access to real-time, decentralized, and secure oracle data.
- Integration unlocks new onchain use cases, from DeFi trading to RWA tokenization, backed by Chainlink’s $25T+ transaction infrastructure.
Chainlink has expanded its footprint in decentralized finance with the launch of Chainlink Data Streams on the Sei Network, now adopted as the preferred oracle infrastructure. The move cements Sei’s position as a high-performance Layer 1 blockchain tailored for crypto markets, while providing developers with institutional-grade data feeds.
Strengthening DeFi With Low-Latency Oracle Data
Sei Network will now integrate Chainlink Data Streams to deliver secure, low-latency, and verifiable price data for decentralized applications. Features such as sub-second execution speed, liquidity-weighted bid-ask spreads, and real-time price accuracy make it an essential tool for DeFi protocols focused on trading, derivatives, and lending.
The integration arrives as crypto adoption accelerates globally. Chainlink’s infrastructure already trusted to secure over $25 trillion in onchain volume provides the reliability and transparency required for institutional-grade applications. With Sei’s parallelized execution and sub-second finality, developers gain a foundation to build faster and more efficient crypto products.

Bridging Traditional Data and Onchain Finance
Chainlink recently announced a partnership with the U.S. Department of Commerce to bring official economic indicators like GDP and inflation data onchain. This new integration with Sei positions the network as a hub where real-world financial data and blockchain-native markets intersect.
By combining Chainlink’s oracle technology with Sei’s performance, the partnership strengthens crypto use cases beyond trading supporting tokenized real-world assets (RWAs), cross-chain liquidity, and next-generation DeFi applications. Developers and institutions now have access to a data solution that meets the standards of transparency and reliability demanded in digital asset markets.
With Chainlink Data Streams now powering Sei, the network is positioned to attract more institutional players and push forward the evolution of crypto finance.
Notably, Chainlink’snSmart Value Recapture (SVR) system has surpassed $1.1 million in recaptured non-toxic liquidation MEV, processing more than $32 million in liquidations on Ethereum. This milestone reflects growing adoption of SVR as DeFi protocols seek to redirect value from third-party extractors back into their ecosystems.
