Key Takeaways

Chainlink Data Streams is now live on the Sei Network to provide high-frequency and accurate market data.
This integration supports real-time tokenization and DeFi applications, enhancing Sei's institutional and DeFi capabilities.

Sei has integrated Chainlink Data Streams into the Sei Network as its preferred oracle solution, according to a Wednesday announcement. The rollout brings low-latency, high-frequency market data to power real-time DeFi and trading applications.

“We’re excited to see Chainlink Data Streams integrated on Sei, as this expands Chainlink’s footprint into a fast-growing ecosystem that supports next-gen DeFi protocols and institutional use cases,” said Thodoris Karakostas, Director of Blockchain & Product Partnerships at Chainlink Labs.

The integration comes as institutional adoption of blockchain infrastructure gains momentum.

Chainlink’s recent partnership with the US Department of Commerce will bring Bureau of Economic Analysis data on-chain to Sei Network, including Real GDP, PCE Price Index, and domestic purchasing metrics.

Sei, a layer 1 blockchain featuring EVM compatibility and parallelized execution, will utilize Chainlink Data Streams for various features, including sub-second price latency, high data accuracy, and liquidity-weighted bid-ask spreads. The infrastructure has enabled over $25 trillion in on-chain transaction volume for DeFi applications.

“Chainlink Data Streams has been integrated as the preferred oracle infrastructure for Sei, bringing highly accurate and reliable price information to the Sei ecosystem,” said Justin Barlow, Executive Director at Sei Development Foundation. “Data Streams’ ultra-low-latency delivery of market data, coupled with its battle-tested infrastructure, makes it an obvious choice for the Sei ecosystem.”

Sei has processed billions of transactions across more than 60 million wallets and has become the top EVM chain by number of active users. The platform is backed by investors including Multicoin, Jump, Coinbase Ventures, and Circle Ventures.
