APRO is a secure oracle platform that combines off-chain computation with on-chain verification to enhance data accuracy, efficiency, and flexibility for decentralized applications. Its core product, the APRO Data Service, allows DApp developers to build customized solutions while ensuring security and reliability.

The APRO Data Service supports two data delivery models: Data Push and Data Pull. The Push model enables decentralized node operators to continuously update price feeds on the blockchain, improving scalability and timeliness. The Pull model allows dApps to request data on demand, offering high-frequency, low-latency access that minimizes on-chain costs and makes it ideal for DeFi protocols and decentralized exchanges.

By integrating a hybrid architecture of on-chain and off-chain resources, APRO ensures security, stability, and high performance. It employs a multi-network communication scheme and a TVWAP price discovery mechanism to prevent manipulation and ensure fairness, making APRO a reliable foundation for diverse blockchain applications.
