Oracles

Oracles let smart contracts use external data that has been published onchain. On Eden, RedStone price feeds are available for builders who need TIA/USD or ETH/USD reference prices.

RedStone on Eden

RedStone provides price feeds through a push-model architecture. Dedicated feed contracts expose price values directly, while the multi-feed adapter emits events that can be indexed by tools such as Goldsky.

Reading a feed

Use RedStone's dedicated price feed contracts for direct reads.

• Call latestAnswer() to read the latest value.
• Call decimals() to scale the value for display.
• Call latestRoundData() and check updatedAt if your app needs to reject stale prices.

Indexing oracle updates

The RedStone multi-feed adapter emits ValueUpdate events. See the Goldsky quickstart and Goldsky example for indexing those updates on Eden.
