Today, those "coincidental transfers" on the blockchain are once again being used as material for conspiracy theories. In fact, many times, if you break down the transaction paths, it's not that mysterious: the same batch of funds is split into several parts, first passing through a common intermediary address, then moving across different protocols, and finally arriving at the target address. To put it simply, it's like moving house—stacking boxes in the hallway first, then distributing them into different rooms.

Recently, that mainstream public chain is about to upgrade/maintain, and the group is starting to speculate whether projects will migrate collectively. I actually prefer to see whether these "coincidental" paths become shorter before and after the upgrade, or if there's suddenly an extra cross-chain step. Narratives tend to lag behind the flow of funds by half a beat.

When it comes to security, I’m willing to take an extra step: before large transactions, I first run the full process with a small amount. It’s slower, but at least I won’t immediately become a teaching case... that’s how I do it for now.
