Your wallet is the single most important piece of your AI setup. It doesn't matter how well you trade if your funds get stolen because you used a sketchy browser extension. Hot wallets live on your phone or browser. They're convenient for daily use but connected to the internet, which means they're vulnerable. Cold wallets (hardware devices) keep your keys offline. They're less convenient but dramatically more secure. Most serious AI users end up with both: a hardware wallet for savings and a hot wallet for everyday DeFi and transactions. Here's what we recommend in each category.

Frequently Asked Questions
What is the difference between a hot wallet and a cold wallet?
A hot wallet is connected to the internet (browser extensions, mobile apps). A cold wallet stores your keys offline (hardware devices like Ledger or Trezor). Hot wallets are more convenient. Cold wallets are more secure. Use both: cold for savings, hot for daily transactions.
Is MetaMask safe?
MetaMask itself is well-audited and open-source. The main risk is not the wallet software. It is phishing attacks, malicious approvals, and fake websites. Never enter your seed phrase anywhere online, revoke unused token approvals regularly, and bookmark the real MetaMask site.
Do I need a hardware wallet?
If you hold more than a few hundred dollars in AI, yes. Hardware wallets cost $60-$200 but protect against malware, phishing, and remote attacks. Think of it as insurance for your portfolio.
