By the end of this tutorial you will understand how to intergrate your dApp built on Celo with **RedStone oracles**.

This document will cover:

*   What is RedStone?
    
*   How to use RedStone?
    
*   Examples
    

🚀 What is RedStone?[​](https://docs.celo.org/protocol/oracle/redstone#-what-is-redstone)
-----------------------------------------------------------------------------------------

**RedStone** is a data ecosystem that delivers fast and accurate financial information in a decentralised fashion using an innovative approach of on-demand data fetching.

RedStone offers a radically different design of Oracles catering for the needs of modern Defi protocols.

*   Leverage Arweave blockchain as a cheap and permanent storage
    
*   Use token incentives to motivate data providers to maintain data integrity and the uninterrupted service
    
*   Use signed meta-transactions to deliver prices on-chain
    
*   Although the data at RedStone is persisted on the Arweave chain, it could be used with any other blockchain
    

You can read much more about the RedStone protocol [in the RedStone compiled documentation.](https://github.com/redstone-finance/redstone-node/blob/main/docs/COMPILED_ORACLE_DOCS.md)

📈 What data is available[​](https://docs.celo.org/protocol/oracle/redstone#-what-data-is-available)
----------------------------------------------------------------------------------------------------

Thanks to our innovative architecture, we offer more than one thousand of pricing data feeds, including tokens, stocks, ETFs, commodities, and much more for a fraction of regular Oracles integration costs.

You can check available assets and data providers using [app.redstone.finance.](https://app.redstone.finance/)

🔥 How to use RedStone?[​](https://docs.celo.org/protocol/oracle/redstone#-how-to-use-redstone)
-----------------------------------------------------------------------------------------------

**IMPORTANT**: RedStone contracts are still undergoing security audit and we are working on the infrastructure secutiry improvements. So, before using RedStone oracles in production dApps, please reach out to us [on Discord.](https://redstone.finance/discord) We will be happy to help you with the integration and will set up a new pool of data provider nodes if there is a need.

Please read this [short documentation](https://github.com/redstone-finance/redstone-evm-connector/blob/master/README.md) to learn how to integrate your dApp with RedStone oracles.

💡 Note: currently RedStone is integrated only with `ethers.js` library, so in order to use it on Celo blockchain dApps you should use [ethers.js](https://docs.ethers.io/v5/) along with [@celo-tools/celo-ethers-wrapper](https://www.npmjs.com/package/@celo-tools/celo-ethers-wrapper).
