These days, I was "educated on delays" again by on-chain data... For the same transaction, I still haven't seen it succeed in my wallet, but the browser shows confirmed first, then switching to a different RPC makes it pending, almost making me think I clicked the wrong chain. To put it simply, what you see as "on-chain" is actually a view assembled by nodes/RPC/indexers, and if any of them lag, it gets delayed. Especially with new L1/L2 incentives boosting TVL, the chain gets busier, and it's not unreasonable for veteran users to complain about mining, selling, and so on. Later, I thought it was pretty funny—I was really heart pounding during those few seconds. Anyway, when I encounter anomalies now, I check two sources, and if necessary, directly verify the raw transaction, and try small positions first—don't be fooled by the "seems to have arrived" to add more.
