The better AI gets, the more you need a separate machine just for your wallet. Nowadays, AI tools like AI keyboards, Claude, Codex—if you want them to run smoothly, they basically need near-complete control of your computer. Reading your clipboard, taking screenshots, typing—these tools can do it all. Normally, this is called efficiency, but when it comes to your wallet, it’s a ticking time bomb. Private keys, seed phrases, verification codes—if any of these linger on your clipboard for even a second, they could be gone. So whenever I deal with wallets, I always use dedicated machines: Wallet isolation (based on asset size) ├─ Small daily amounts, hot wallet → Use an old machine exclusively, don’t install random stuff ├─ Large holdings, cold wallet → Use an offline machine, never connect it to the internet └─ Frequent trading, exchanges → Use a separate machine, only log into exchanges The risks are hidden; you won’t see them beforehand. The only way to block them is through physical isolation. Luckily, a MacBook Air is still dirt cheap these days. Among the recent hardware price hikes, Apple’s been pretty reasonable—spending on a separate machine is way cheaper than losing your private key. When can we relax on this setup? When AI permissions truly operate in a sandbox, and there’s system-level isolation for clipboards and keys. Until then, having an extra machine is just an extra layer of insurance.
