I almost sent myself away just now... Transferring a small amount on the mainnet, I accidentally pressed an extra character while copying the address, and the wallet actually popped up a "New address not verified" warning, and I only realized what happened then. Mainnet gas is expensive, but that brief "pain" actually forces you to slow down; L2 is cheap and smooth, and when you click quickly, people tend to get carried away.

My current compromise is pretty old-fashioned: for daily interactions and frequent small transfers to L2, I really prefer to spend a bit more gas to go back to the mainnet and do it slowly, at least I can see every step. Honestly, anyone can boast about narratives, but security is something you have to tighten yourself—don't save on transaction fees at the cost of your life.
