The key, not the coins
Open it: no coins inside.
A wallet holds a private key — the signature that controls your assets.
The assets live on the blockchain. They never leave it.

Hot, because connected
The key lives on a device wired to the internet: that makes it “hot”.
A cold wallet holds the same key — unplugged, out of the network's reach.
The magic
Pay. Trade. Connect to an app in one tap.
Your signature leaves the phone, and the chain records it, link after link.
Phishing
Fake site
Malware
Watched screen
The attack surface
Connected also means exposed.
A fake site. A phishing link. A poisoned app. A watched screen.
Every threat is after the same thing: your key.
The golden rule
Twelve words. That's your entire key, written in plain sight.
Whoever holds the words holds everything. No one legitimate will ever ask for them.
The right habits
- 01Keep only small amounts in it
- 02Check every address before sending
- 03Install the official app only
- 04Back up the twelve words offline
