Recently, Layer 2 has started competing again in TPS, transaction fees, and subsidies, causing quite a stir, but I find the more worrying issue is wallet security. Mnemonic phrases, to put it simply, are your lifeline—don’t screenshot, don’t store them in the cloud, don’t send them to “customer service.” Making two offline copies and keeping them secure is better than anything else. The same goes for signing authorizations—don’t just click “claim for free” or “airdrop subsidy” all the way through; first, check whether the permissions require unlimited access or if assets will be transferred away.

I thought I was cautious enough, but a few days ago I almost authorized my main wallet on a “cross-chain acceleration” page… the page looked just like the real thing. Later, I realized the link’s domain was suspicious, so I quickly closed it—cold sweat. Anyway, I now test new protocols with a secondary wallet first; if possible, I avoid connecting to the main wallet altogether, just to be safe.
