Using Quex Oracles

By the end of this tutorial, you'll understand how to integrate your dApp built on Celo with Quex oracles.

  • Examples

🚀 What is Quex?​

Quex is an oracle protocol designed to securely transfer verifiable off-chain data to on-chain smart contracts using confidential computing proofs. Quex oracles enable dApps on Celo to securely and reliably access real-world data, allowing developers to create advanced, trust-minimized financial applications, parametric tokens, prediction markets, and more.

Key benefits of using Quex:

  • Confidential Computing: Ensures data integrity through verifiable cryptographic proofs.
  • Flexible Data Sources: Easily connect and verify data from any off-chain HTTPS API.
  • Cost-efficient: Optimized oracle callbacks reduce on-chain storage costs and improve transaction efficiency.
  • Post-processing: Flexible on-chain data transformation using programmable response filters (e.g., jq scripts).

You can explore more about Quex on the official documentation page.

📈 What data is available?​

Unlike traditional oracles, Quex allows you to securely make verifiable API calls to virtually any off-chain data source, including private APIs protected by credentials. This means you can literally access the entire internet with no limitations!

🔥 How to use Quex oracles?​

IMPORTANT: Quex contracts are currently undergoing security audits and infrastructure security improvements. Before using Quex oracles in production dApps, please reach out to us on Discord. We'll be happy to assist you with the integration and, if needed, set up a dedicated data oracle pools if there is a need.

Please refer to this short documentation to learn how to integrate your dApp with Quex oracles.

🔥 How to use Quex oracles?​

IMPORTANT: Quex contracts are currently undergoing a security audit, and we are actively working on infrastructure security improvements. Before using Quex oracles in production dApps, please reach out to us on Discord. We’ll be happy to assist you with integration and, if necessary, set up a dedicated pool of data provider nodes.
