Chainlink Push Engine Feeds

Overview

Pharos has deployed Chainlink self-managed price feeds using the Chainlink Runtime Environment (CRE). A CRE workflow periodically fetches price data from the Chainlink Data Streams API, checks deviation and heartbeat thresholds, and pushes updates on-chain to a central cache contract.

Each price pair has a dedicated proxy contract that exposes the standard Chainlink Data Feeds interface, allowing any on-chain consumer to read the latest price via latestAnswer().
