I just accidentally copied a string of addresses and missed two characters, and when I opened it up, the "on-chain" display showed the transfer failed. I was relieved... Then two minutes later, the same transaction slowly appeared in another browser, almost making me think I traveled through time.

Later I thought about it and it makes sense; what you see as "on-chain" is actually the translation of the node/RPC/index system, some are fast, some are slow, and some even get stuck.
Especially recently, with the incidents of stolen cross-chain bridges, everyone loves to say "wait for confirmation," but honestly, it's not just about confirming the block; sometimes it's about waiting for your data pipeline to stop acting up.
And during that oracle anomaly, when the price fluctuated, the community immediately entered "wait and see" mode. I quietly opened several RPCs for comparison... Anyway, tonight I'll keep working on the address relationship map, meow for now.
