Lately, I've been watching the Layer 2 projects argue over TPS, fees, and subsidies which one is more attractive, but I'm actually more concerned about: if your wallet gets phished and wiped out, no matter how fast it is... As for mnemonic phrases, honestly, just don't upload them to cloud storage or screenshot them; keep them offline if possible. Don't rush to sign transactions; for those "Approve unlimited" permissions you don't understand, I'd rather spend a bit more gas and redo it. Yesterday, a colleague asked me, "How dangerous can airdrop pages really be?" I could only say that, many times, it's not that you're inexperienced, but that the phishing sites are made to look so convincing. Anyway, now I first test new links with a small account, regularly clear authorizations, and it also helps me avoid some PTSD.
