As DeFi and blockchain games grow wildly across more than forty public chains, a neglected problem has finally surfaced: data is still stuck in the prehistoric era.

Imagine you develop a cross-chain game—players farm equipment on Arbitrum, synthesize items on Polygon, then trade gear on BNB Chain. The process is seamless until the last moment: data from the three chains simply doesn't match. The game crashes during settlement, and users' assets vanish into thin air.

This isn't a horror movie about the future; it's a real scenario for every multi-chain entrepreneur in 2025. Data silos act like communication chasms, forcibly dividing the value that should be flowing freely. APRO has identified this critical pain point and decided to create a central nervous system for cross-chain data.

Currently, it has integrated with over 40 mainstream public chains and Layer 2 solutions, covering a broad spectrum.

The problem is quite painful: most oracles still operate using the primitive single-chain model, like each chain using a different ledger. When user assets jump between ten chains, price information, game states, and asset rights data all become scattered.

APRO's approach is straightforward—verify once, synchronize across all chains. Once an asset's price on Ethereum is confirmed, this "fact" is immediately broadcasted to all connected chains. Arbitrage opportunities disappear, and data latency becomes meaningless.

From the moment of its architectural design, APRO is no longer a supporting role for a single chain but aims to build a true cross-chain infrastructure. Two engines advance side by side, delivering data with the precision of food delivery—
