Recently, discussions about AI and RWA within the community have remained hot. As a long-term active participant on the chain, I decided to test APRO—this oracle product focused on the Bitcoin ecosystem. During the three-day usage period, I gained a lot and also identified some areas that need optimization.

Why focus on APRO? Honestly, the established players in the oracle track, such as Chainlink and Pyth, have already formed competitive barriers. But APRO's core differentiation is very clear—it is entirely designed around the Bitcoin ecosystem. This choice is actually very forward-looking. Currently, the Bitcoin L2 ecosystem is booming, with new asset layers like Runes, BRC-20, and Ordinals emerging endlessly. Traditional oracles indeed have shortcomings in adapting to Bitcoin. APRO directly targets this niche, making its positioning particularly clear.

First-hand experience of actual operation: the documentation is quite complete, but explanations of some key steps can be tricky. For example, the Data Pull workflow requires pulling report data from the Live-API and then submitting it to the VerifierProxy contract for validation. The logic itself is sound, but managing fees can be a bit cumbersome. You must authorize (approve) the fee limit in advance, supporting payments with native tokens or wrapped assets. Many first-time users might stumble here. I personally encountered this in my first test—without sufficient pre-funded fee balance, the transaction reverted, wasting gas in the process.

The Data Push mode, on the other hand, is much simpler, with more straightforward call logic.
