Recently, on-chain data keeps "hanging," but actually, it's often not the chain itself having issues; it's the middle layer struggling... Indexers need to track blocks, Subgraphs need to resynchronize, and RPCs still have rate limits. When you refresh, it feels like chasing an overdue order, returning old cache or directly 429. At this moment, some people are watching large transfers on-chain and abnormal movements in exchange hot and cold wallets, thinking it's "smart money," taking screenshots and starting to speculate. I find it quite helpless: the same transfer showing a few minutes' difference across different data sources is normal. Anyway, I now open two sources for comparison; I'd rather be slower than be led by delays... Let's see.
