Honestly, lately I've been hearing everyone talk about "real-time on-chain," and I have some doubts: the "on-chain" you see is often just a perspective pieced together by nodes/RPCs/indexers, not something you immediately know as soon as a block is confirmed. RPC congestion, node desynchronization, indexers still processing data—your page will lag behind, or even temporarily show "nothing happened." I'm not sure if I'm just being too sensitive, but the display speed for the same transaction can vary quite a bit across different wallets or RPCs.

Recently, AI agents automatically placing orders and interacting have been hyped up a lot, but if they rely on a slow indexer or unstable RPC, it's easy to make decisions like "think it succeeded" or "think it failed"... Anyone can tell a story, but safety and data sources are actually the most easily overlooked parts. Anyway, when I encounter on-chain anomalies now, my first reaction isn't to curse the chain, but to switch RPCs, check the raw transaction on the block explorer, and then decide whether to continue.
