Blocksense
Blocksense is the ZK rollup for programmable oracles — a fully decentralized protocol enabling permissionless, verifiable, and cost-efficient data feeds for Web3. We unify oracles, compute, and interoperability into one open middleware layer, empowering builders to securely bring real-world data on-chain at scale.
Programmable oracle SDK
Create and deploy custom oracles permissionlessly via our Oracle Script SDK. Developers can ingest any web-accessible data, perform transformations, and publish securely on-chain. The SDK supports both read and write operations through zkTLS for bi-directional smart contract interactions
High-frequency price feeds for DeFi
Blocksense delivers secure and cost-efficient price feeds tailored for lending markets, CDPs, RWAs, prediction markets, and more. These feeds are live across multiple testnets and onboarding to mainnet. They are already integrated into early deployments with partners in the DeFi ecosystem. Each of the 700+ currently live feeds is designed for high accuracy, with automatic smoothing mechanisms and configurable update frequency. Our peg-aware oracle logic dynamically adjusts pricing during volatility events to mitigate liquidation risk.
