## @didi_xbt (Didi ♱) · 10-11 17:23 · ♥59 ↻20 💬41 I once asked if people knew what a cold wallet was, sadly lots of people think “its a wallet that is cold”
Well Tangem is an example of cold wallet and a cold wallet is a hardware wallet (we need a web3 school atp)
@Tangem is a hardware wallet that comes as a credit-card-sized NFC card (or a ceramic ring).
No battery. No cables. No screen. No USB.
You manage everything through the Tangem app on your phone. When you want to send or sign a transaction, you simply tap the card to your phone.
The private key is generated and stored inside a Samsung EAL6+ certified chip and never leaves the device.
How backup works By default it’s seedless. A 2- or 3-card set all hold the same wallet. Any one card can sign.
You can also choose to create a traditional 12/24-word seed phrase if you prefer.
Key points • Setup takes about 2 minutes • Supports 14,000+ tokens across 90+ networks • Works with WalletConnect for dApps • IP69K durable, 25-year warranty • Phone lost or stolen doesn’t compromise funds (keys stay on the card)
So if you want to download the wallet, make sure to use my code → DIDI1 (fastest way to make 6 figs btw) https://x.com/didi_xbt/status/2109334101601747412
