I just did something stupid... When copying the address, my hand trembled and I pasted the recipient address as the last testnet one. The moment I clicked confirm, I felt my heart sink. Luckily, I hadn't broadcasted it on-chain yet, so I withdrew and started over. As a result, I also experienced what it means to "cut in line": for the same transaction, others can rely on higher tips or better sorting to jump ahead of you, and you either spend more money or get slippage eaten away. The worst part is, even though you're following the interaction process, in the end, it feels like you're taking a bullet for someone else.

Honestly, MEV might be a strategy for big players, but for someone like me who’s just doing airdrop interactions, it’s more about the "cost" and "whale risk" adding an extra layer of uncertainty: you think you're interacting with a contract, but in reality, you're racing against a bunch of invisible bots.

Recently, everyone’s been talking about modularization and Layer 2 DA, and developers are super excited, but I, as an ordinary user, am pretty confused... I don’t really understand how the underlying layers are broken down and assembled. I just care about whether my transactions can avoid being cut in line, and whether I can prevent a simple slip-up from costing me. Anyway, I treat each interaction as paying a "toll," saving where I can and taking it slow where I need to.
