In a decentralized world, many people think of "oracles" as simple price feeds — a smart contract asks, "What is the current BTC price?" and then receives the latest transaction price, and that's that. However, for real fund management, risk control, and investment strategies, knowing just the last transaction price is far from sufficient. The true "vitality" of a mature market is reflected in multiple dimensions such as order book depth, dynamic trading volume, and major buying and selling forces. An oracle that only provides the final transaction price is often just an ear that cannot hear the internal movements of the market.
The design thinking and development direction of APRO Oracle is to give smart contracts real market perception capabilities — a data engine similar to an 'on-chain radar' that does not just look at a single transaction but reads the market's structure and power from a panoramic perspective. This is precisely the infrastructure capability that future DeFi, algorithmic trading, synthetic asset pricing, and even derivatives protocols truly need.
Traditional oracles only look at the last price — this is not enough.
Ordinary oracles are like price tags in the market: they tell you 'what the last transaction price was', and contracts make judgments based on that, such as whether to trigger liquidation or update collateral rates. While it is valuable in many scenarios, it has obvious limitations:
It does not know the market depth behind the price — is the power between buyers and sellers balanced?
It does not know the shape of the order book — is it one-sided suppression or healthy liquidity?
It does not know the transaction volume trend — is the market quiet or suddenly erupting?
These cannot be expressed by a single price, but are crucial for those who truly want to understand the market and the protocols.
APRO, in this demand gap, proposes a brand new oracle concept — not only transmitting values but also allowing contracts to understand the data itself.
APRO: The 'depth radar' that lets on-chain understand the market.
APRO's data service is not just a simple transfer of the last transaction price from a website or exchange, but combines off-chain processing + on-chain verification in a dual-layer architecture, allowing smart contracts to see a more complete picture of the market.
According to the official documentation, APRO's data service supports two modes:
✅ Data Push (active push)
APRO nodes continuously collect information from multiple data sources and actively push data on-chain when prices or other indicators trigger certain changes, so contracts do not need to pull data constantly, saving gas fees and ensuring timeliness.
🎯 Data Pull (on-demand retrieval).
Contracts can instantaneously request the latest data from the APRO network when needed, which is suitable for scenarios sensitive to delays, such as high-frequency trading and derivatives liquidation.

The combination of these two modes allows APRO's data to be both real-time and cost-saving, truly meeting the needs of various on-chain businesses.
APRO's dual-layer architecture greatly enhances data credibility.
APRO's network adopts a very clever dual-layer mechanism:
🔹 OCMP (off-chain message protocol) first layer: Multiple off-chain nodes are responsible for data collection and aggregation, distributedly collecting data from different exchanges, different order books, and different liquidity pools, not just looking at the last transaction.
🔹 Second-layer verification (similar to Eigenlayer's dispute resolution layer): When data needs to be put on-chain, there is a second layer for verification to avoid the influence of malicious nodes or abnormal data.
This design not only reduces single point failure risk but also enhances the whole network's ability to control data quality. For protocols that truly rely on price and market depth decisions, this is a brand new trusted infrastructure.
Why is 'market depth' more important than 'last transaction price'?
For a serious investment portfolio or decentralized protocol:
📌 Price is the result, while depth is the process — a single transaction is just the result, while order book depth, order power, and transaction volume trends are the root drivers of price.
📌 Thin markets lead to large slippage and high risk — the last price may completely be a random value under low liquidity, but APRO can help examine whether there is a thin liquidity risk.
📌 Automated strategies require richer inputs — algorithm strategies, liquidation logic, dynamic collateral rate adjustments, etc., all need to understand the internal structure of the market, not just the final transaction price.
In simple terms, if you only look at the numbers, you will always be a passive observer of the market; but if you can understand the power dynamics and the market's elasticity to shocks, you can build more robust, safer, and more profitable strategies.
APRO's design serves this goal; it does not just provide results but also gives reasons and context.
Specific application scenarios:
🪙 Decentralized lending and liquidation protocols.
When prices suddenly fluctuate significantly, traditional oracles may report the latest prices but do not know whether there is deep support behind those prices. This can easily lead to misjudgments in liquidation based on lending protocols. APRO allows contracts to reference broader data, avoiding being misled by isolated transaction prices.
📈 Derivatives and options pricing.
The derivatives market needs to understand actual liquidity and the real-time dynamics of the order book, not just the price, as settlements and risk models must be based on the overall market state.
🤖 Quantitative strategies and automated arbitrage mechanisms.
A truly efficient automated strategy requires a complete view of the market, and the 'depth chart' created by APRO through collecting multi-source market information is just such a view.
APRO's advantages lie not only in the volume of data but also in its intelligent processing.
APRO's official documentation indicates that it combines off-chain computation with on-chain verification in a hybrid node architecture, enabling the system to have both efficient processing capabilities and high reliability.
It can provide not only price data but also support more advanced custom logic in the future, such as on-chain calculations for market trends, transaction density, price volatility statistics, and other comprehensive indicators. This means:
✔ Smart contracts can make decisions based on richer data.
✔ Decentralized exchanges (DEX) can dynamically adjust slippage and fee models.
✔ The risk engine can assess market health in real time.
This is an essential part of the road to a truly mature and secure decentralized financial system.
Ecosystem cooperation and market recognition continue to improve.
APRO is integrating with multiple infrastructure and wallet services in the industry, such as its collaboration with OKX Wallet, allowing users easier access to high-quality on-chain data services.
Moreover, APRO has been integrated into multiple ecosystems as a price data provider, for example, some protocols use its price feeding service to enhance the reliability of their own infrastructure.
These collaborations and references indicate a very important trend: APRO is no longer a marginal project but is becoming a core component of the future oracle ecosystem.
Summary: APRO is building a true 'market depth perception layer'.
If traditional oracles are the price observation points in the blockchain world, then APRO is like the depth radar of the market: it not only focuses on the last price but also understands how the entire market operates, where liquidity is, and where risks may arise. This capability is crucial for the future of complex DeFi protocols, financial instruments, cross-chain asset pricing, and other directions.
APRO is not just telling contracts 'what the current price is'; it is answering a deeper question:
Is the market depth sufficient? How is the power balance? Has the wind direction changed?
For truly serious investment portfolios, hedging strategies, and risk control systems, this capability is more important, reliable, and valuable than a single price.
