DoubleZero Adds Kalshi Order Book to High-Speed Solana Feed

DoubleZero is a dedicated high-speed data network built for blockchains including Solana. It launched DoubleZero Edge on April 16, using private fiber and multicast technology to distribute raw blockchain data more consistently than the public internet. The infrastructure matters because institutional market makers and quantitative firms compete on milliseconds: earlier access to order and transaction changes can sharpen pricing, hedging and signal generation, while reducing the uncertainty traders otherwise build into spreads and execution costs.

DoubleZero said on Aug. 13 that Edge will add real-time order-book data from Kalshi, the U.S.-regulated prediction-market exchange, marking an expansion from Solana’s raw onchain feed into offchain venue data. The company has said its dedicated network can cut delivery times by tens of milliseconds, particularly during congestion, and that subscribers pay for feeds in USDC. The companies did not disclose the value of the agreement or a full rollout timetable, leaving the commercial scale and initial subscriber base unspecified.
