These days, watching everyone focus on whether a major public blockchain is upgrading/maintaining and guessing if projects will migrate, I actually care more about: the "on-chain data" you see might already be a bit behind.

Many people think they are looking at the block, but actually they are looking at the results output by nodes/RPC/indexers—if a node is slightly behind, RPC is rate-limited, or index rebuilding gets stuck, the page can show a scene of "funds retreating/address movements."
It's like looking in the rearview mirror or listening to a delayed live broadcast; emotions run ahead, but the facts are still on the way.
Anyway, when I encounter anomalies, I first switch RPCs for comparison, then check the original transaction and cross-verify with different browsers.
I'm not in a hurry to draw conclusions; black swans usually start from "how is this different from what I see."
