First-Party Crypto Data for Chainlink
Powering Chainlink Oracles with Real-Time Crypto Data
Blocksize is a first-party data provider in the Chainlink oracle network. We stream real-time crypto price data to 25 Chainlink Oracles, powering feeds across Ethereum, Polygon, Avalanche, and zkSync. Integrated via Chainlink’s adapter framework, our data helps secure decentralized applications with trusted on-chain pricing.
NEW: State Pricing Feature
Many crypto assets trade in environments where real liquidity is sporadic.
Blocksize's new State Pricing infers the price at which the market would trade if meaningful liquidity were present.
