Oracles

SUPRA

HashKey Chain leverages Supra's advanced oracle technology to provide reliable and accurate real-world data feeds. Recognizing the limitations of traditional oracles, such as dependency on trusted intermediaries and latency issues, Supra developed the Distributed Oracle Agreement (DORA). This innovative solution utilizes a high-performance consensus algorithm to aggregate price data from up to 21 sources, ensuring data integrity through Byzantine Fault Tolerance.

See this guide to learn how to use the SUPRA Oracles.

APRO

HashKey Chain integrates APRO's innovative Data Push technology to deliver reliable and timely price feeds. Utilizing a threshold-based data model, APRO's decentralized node operators continuously aggregate and push updates to the blockchain when specific price thresholds are met. This approach enhances scalability and ensures real-time data delivery, making it ideal for DeFi protocols and smart contracts.
