Smart contracts have a classic challenge—they can only execute the logic of the code you write, and once real off-chain data is involved, they become blind. This is the core problem that APRO aims to solve.

Instead of treating data oracles as an add-on feature to be forcefully integrated, it's better to design them as true infrastructure. APRO's approach is just that—transforming a wide variety of chaotic off-chain signals into clean, verifiable data facts, so that smart contracts can use them with confidence.

How is this achieved? The key lies in the flexible combination of two delivery schemes. Do trading bots need a continuous stream of real-time market data? Does the hedging system need to stay constantly updated on market movements? APRO's Data Push mode is tailor-made for these scenarios—continuously pushing the latest data to ensure trading systems always have fresh market information. On the other hand, there's also a pull mode for applications that don't require high-frequency updates but demand absolute data reliability.

In simple terms, APRO is redefining how oracles work—from passive tools to active data infrastructure.
