These days, some people are treating "on-chain data" as if it's a live broadcast again.

I find it a bit funny but also a little unsettling... The swap or large transfer you see on your phone is often a "paraphrased version" provided by nodes/RPCs/indexers, and it's normal for it to take a few seconds to a few minutes.
Especially when the market is volatile, RPC rate limiting and indexer queuing happen, and while the page is still refreshing, you might think you're watching the truth, but you're actually just tracking the delay.

Recently, AI agents and automated trading have been quite popular.
Some people hype them up as if they can print money on their own, but honestly, no matter how smart they are, they still rely on these entry points to read the chain and send transactions.
If the entry point jitters, mistakes are easy to make.
What I care more about now is: on the same chain, I cross-check data from two sources, and I try not to use "a newly appeared event" as the only signal for triggering.
Don't be too hard on yourself.
