Dear developers, I have to vent. Recently, we deployed our DApp across several chains—Ethereum, Solana, Base, Aptos—and almost tore the team apart—everything was stuck on the oracle issue.

Everything went smoothly on Ethereum, calling Chainlink for price feeds, a few lines of code to handle it. But once we moved to Solana, the documentation changed completely, and we had to research Pyth integration. When it came to Base, it was another set of deployment logic for Chainlink on L2. Different chains, oracles are like power outlets in different countries—interfaces, fees, update frequencies are all different. We kept messing around, wasting a month, just acting as "oracle adapters" all day.

Seeing the workload of 40 chains piling up in front of me, I was almost hopeless. Later, I tried the APRO multi-chain oracle solution. To be honest, I was quite skeptical at first—everyone's tired of hearing "support all chains." But after using it, it really felt different—it effectively solved some of the most critical pain points.

For example, deployment efficiency. Previously, each chain required manual configuration of consumer contracts, setting data sources, testing price feed delays—doing this for 40 chains could take until the end of the year. Now, with a few clicks in the backend to select the data types needed, and deploying to multiple chains with one click, it saved a developer’s workload. For our small team, the effect is quite noticeable.
