When developing DeFi applications, where does the price data come from? This is a pain point for many developers.

Maintaining your own nodes is too costly, and relying on centralized data sources raises security concerns. APRO's oracle solution directly addresses this issue—it aggregates price data from multiple independent nodes within the ecosystem, cross-verifies the data, and then pushes it directly on-chain.

How does it work? Each price pair has a corresponding on-chain address. Your smart contract can simply call a function to read the data, without needing to build complex data retrieval logic yourself. Common trading pairs like BTC/USD, ETH/USDT are supported.

Why is this solution reliable? The benefit of a decentralized node network is that there is no single point of failure. If one node encounters issues, it doesn't affect the overall system, and the difficulty of data manipulation is greatly increased. This is especially important for scenarios requiring high precision and timeliness, such as high-frequency trading, liquidation prices for lending protocols, and settlement prices for derivatives.

It's also cost-effective. It saves the manpower and hardware investment needed to run your own nodes, and significantly reduces the complexity of data integration. Currently, this solution has been adapted to mainstream public chains and major assets, ready for immediate deployment.

In summary, if you're struggling with on-chain data sources for smart contracts, this decentralized and hassle-free oracle solution is definitely worth considering.
