I almost had a mishap just now... Transferring funds on-chain, I accidentally copied the last two digits of the address incorrectly. Luckily, when the wallet popup appeared, I suddenly felt something was off, so I went back and checked three times before daring to click confirm. As soon as I confirmed, I realized there were so many people queued in the mempool, it was ridiculous—like rush hour on the subway: you think you've boarded, but you're actually just at the station.

During congestion, transactions tend to follow this fate: they hang out in the pool first, miners/validators pick the "tips they prefer to give" and bundle those first; if you send too little, you'll wait patiently, and after waiting, your transaction might expire or get replaced by your own higher fee (the same nonce set—basically, replacing the old with a new transaction). The most torturous part is that "neither failed nor succeeded" dangling state, staring at the browser refresh, the mental stress more intense than watching candlestick charts.

Recently, everyone’s been talking about modularization and the Data Availability layer, which makes developers’ eyes light up but leaves users confused. I think, no matter how the narrative is spun, in the end, for ordinary people, it boils down to: don’t click recklessly during the busiest times, first confirm the address, then estimate an acceptable fee. Otherwise, the first mental game will scare you off. That’s all for now, I’m not going to tinker anymore today.
