Recently I’ve been thinking about wallets. The amount of assets is neither too much nor too little. If I use a hardware wallet, it feels like a bit of overkill, but if I lose it, I’d still be heartbroken. I’ve tried social recovery—its logic is pretty elegant, but in practice you first need to find a few reliable witnesses, and you also have to ensure they don’t lose their private keys. The threshold is actually not low.

My current approach is: for everyday on-chain interactions, keep a hot wallet; for larger funds (anyway, there isn’t much), store them in a hardware wallet. I sometimes use multisig as a backup safe. Recently I’ve also been seeing AI Agents being hyped with automated trading, but honestly, the security audits of those contracts haven’t been finished yet—I’ll wait and see.

Yesterday I casually tested a new protocol. The interaction gas fee was 0.003 ETH. When I checked the address, the contract code had some strange permission on a sell-order address—scared me enough that I immediately withdrew. Anyway, don’t believe in anything like “one-click wealth freedom.” First, take good care of your own private key.
