I saw an address sending 0.042 ETH to contracts on three different chains in the same second — same amount, same gas price. My first thought was a bot malfunction, but digging deeper, it turned out to be a cross-chain message split into three "coincidental" payments — essentially the modular architecture, where the DA layer slices and distributes data, making it look like random money transfers to the user.

Quite interesting — many "mysterious" on-chain phenomena are just engineering compromises when you break them down. I used to panic when I saw transfers like this, but now I first check the timestamps, since rushing doesn't help anyway.

The DA layer concept is trending lately, with developers talking about it excitedly. I don't fully understand it yet, so I'm just observing which bridges are actually using it to save costs. If I don't understand something, I stay away — that's my boring principle.
