Wallet types

A wallet is really just a keeper of keys — and there’s a whole spectrum of ways to keep them, trading convenience against security. The right answer for most people isn’t one wallet, but a few different kinds for different jobs.

Hot, cold, and everything between

The core question is simply where the keys live — on a device that touches the internet, or one that never does.

Hot wallet

Keys on an internet-connected device — a phone or browser app. Convenient for spending small, everyday amounts, but exposed to malware and hacks. Treat it like the cash in your pocket: handy, but don’t keep your life savings in it.

Cold wallet

Keys kept offline, never touching an internet-connected computer. Far safer from remote attackers. This is where you store savings you rarely move — the vault, not the pocket.

Hardware wallet

A small purpose-built device that stores your keys and signs transactions internally — the keys never leave it, even when plugged into an infected computer. The most popular way to do cold storage well, balancing strong security with usability.

Paper wallet

Keys (or a seed) written or printed on paper and stored physically. Completely offline, but fragile — fire, water, loss, or fading ink can destroy it, and spending from it safely takes care. Largely superseded by hardware wallets and steel seed backups.

The mental model. A small hot wallet for spending, and a hardware (cold) wallet for savings. The pocket and the vault. Most people never need more than these two — a little money where it’s convenient, the bulk where it’s safe.

But even one hardware wallet is still a single point of failure: one device lost, stolen or destroyed. For serious amounts, the answer is to require several keys at once — multisig, next.

Key takeaways

Hot wallets (online) are convenient for spending; cold wallets (offline) are safest for savings — the pocket and the vault.
A hardware wallet signs transactions internally so keys never touch an infected computer; paper wallets are fragile and largely superseded.
