RedStone Oracles

RedStone delivers frequently updated, reliable, and diverse data feeds for your dApp on Manta Pacific L2. RedStone is unique in many aspects, three notable ones are:

  • The most gas-optimized oracle (make your dApp scalable)
  • Unique price feeds (including LSTs, LRTs, RWAs and Manta-native assets)
  • Modular Oracle Design allows for flexibility towards user needs

RedStone operates in two models Core (Pull) and Classic (Push) both available on Manta.

How to integrate RedStone Core?​

Check out RedStone Showroom to see how data delivery with transactions and fetching data from the Demo contract works on Manta. The RedStone Core model allows your dApp to utilize data feeds delivered “on-demand”, only when the data is needed. Thanks to the implementation of the EVM-connector library and extending your Ethers.js, your dApp will be able to attach signed data packages with timestamps to call data of your users’ transactions.

In order to implement the Core model you will need to do two things:

  1. Adjust the Javascript code of your dApp to inject the additional payload with signed data feeds to call data of your users’ transactions (otherwise you will get smart contract errors).
  2. Adjust your smart contracts to include the libraries responsible for data extraction from call data and signature verification.

Please see the specific steps and ready code samples in the Docs.

How to integrate RedStone Classic?​

The RedStone Classic model ensures that data is pushed into on-chain storage via a relayer. Dedicated to protocols designed for the traditional Push Oracles model, that want to have full control of the data source and update conditions (heartbeat and deviation threshold).

The on-chain contracts in Classic enable storing prices and getting them through a familiar interface (e.g. the Chainlink Aggregator).
