Coinbase has integrated Chainlink's DataLink service to publish its exchange market data onchain, marking a significant step in blockchain data infrastructure. This integration allows decentralized finance (DeFi) applications to access institutional-grade market data, including pricing, order book, and derivatives information, directly on blockchain networks. The move enhances Coinbase's data accessibility for DeFi protocols, enabling them to utilize verified market inputs for pricing models and risk management. The integration covers a wide range of datasets from Coinbase, including spot prices, perpetual futures, and derivatives data, extending to Coinbase International Exchange and Coinbase Derivatives Exchange. This development strengthens the technical collaboration between Coinbase and Chainlink, following previous integrations like the Base-Solana bridge secured through Chainlink CCIP. Chainlink's infrastructure standardizes data feeds, facilitating secure delivery of exchange-level data into programmable environments, thereby expanding its role as a key data infrastructure layer in blockchain systems.
