Sei has recently enhanced its ecosystem by integrating Chainlink Data Streams, offering a robust oracle solution on its blockchain. This integration, which went live on September 10, allows Sei to utilize high-frequency market prices, liquidity-weighted bid-ask spreads, and critical U.S. economic metrics, including Real Gross Domestic Product (GDP). By establishing Chainlink as a preferred oracle provider, Sei aims to set new standards for secure, verifiable on-chain data.
The Chainlink integration employs a pull-based model that ensures market data is delivered with sub-second latency. This advancement empowers developers to access comprehensive market insights rather than just single price points, facilitating better risk management and accurate pricing for various DeFi applications, including lending, trading, and derivatives. Additionally, the on-chain access to vital data from the U.S. Bureau of Economic Analysis, such as the PCE Price Index, is expected to pave the way for more sophisticated trading options and institutional use cases.
Sei has seen substantial growth, boasting over 64 million unique addresses and more than 3.8 billion transactions since its inception, as reported by its official block explorer, Seiscan. Recent activity remains robust, with over 2 million transactions and 395,000 new addresses created within a 24-hour period. The network’s Total Value Locked (TVL) currently stands at over $591 million, according to data from DeFiLlama.
The timing of this integration coincides with Sei’s strategic developments, including the filing of a spot SEI ETF by asset manager 21Shares, which has amplified investor confidence. Earlier this year, Sei transitioned from the Cosmos ecosystem to Ethereum, enhancing its compatibility with the larger DeFi landscape.
While promoting Chainlink as its “preferred” oracle, Sei is still committed to a multi-oracle environment, collaborating with competitors like Pyth and Band Protocol. Research indicates that while both Chainlink and Pyth offer low-latency solutions, Chainlink’s performance on Sei is estimated at around one second, compared to Pyth’s approximately 800 milliseconds. This move follows Chainlink’s recent achievement of becoming the first oracle to gain ISO 27001 certification.
