Recently I've been seeing a lot of hype about AI Agents—automated trading, on-chain custody, sounds cool, but honestly my first reaction was—where the hell is my private key.

The mnemonic phrase thing, even though it's been said to death, I'll say it again: handwrite three copies, store them separately, don't take photos or use cloud storage, even my mom knows I keep it in the bank's safe deposit box (not really). Signature authorizations are even more of a trap—many phishing sites look exactly like the real ones, and one click on "approve" turns your wallet into a public restroom. I've developed a habit now: before every authorization, I must check the contract address, even if it's a hassle.

If an AI Agent takes over my signing process, will it be more careful than me? I don't think so.

What about you? Where are you keeping your mnemonic phrase now, and are you really at ease?
