I just picked up my phone and glanced at an on-chain data dashboard. Huh—an LP’s APY suddenly spiked. I thought, could another arbitrage opportunity be back? Then I refreshed it three times and realized it was just my local node lagging by half a beat. Basically, what you see as “on-chain real-time” is information the indexer has processed and then fed to you—first-hand or second-hand. If any RPC node in the middle gets stuck, and then it passes through another layer of API caching, someone might have already taken the cheap deal a few minutes earlier. Lately, with the rumored noise around deposits and withdrawals, everyone is watching on-chain more closely—but ironically, they may end up overlooking these transmission delays. Anyway, my current habit is: before making any big moves, first check whether the RPC I’m using is actually alive—don’t just trust the timestamps shown on the interface. That’s it—I’m going to pull the slow Infura link from my node and switch to another one.
