RedStone

Overview

RedStone is a modular oracle network that delivers price feeds to smart contracts. On Kaia, RedStone exposes Push feeds that store prices on-chain so dApps can read them with a familiar Chainlink-compatible AggregatorV3Interface.

RedStone Push periodically updates on-chain prices based on configurable deviation and heartbeat conditions. Learn more in the RedStone Push documentation and browse live Kaia feeds in the Push Feeds UI.

Using RedStone on Kaia

Each Push feed is deployed as a price-feed contract that implements Chainlink’s Aggregator interface. You can call latestRoundData() to read the latest price.

Pass the feed address for the asset you need (see tables below). Always validate updatedAt and round data against your protocol’s freshness requirements.
