Product description

The ColdCard wallet is a must-have for the true cypherpunk. You need some technical knowledge to handle this wallet, but you also get a lot of security for it in return. 

This hardware wallet has the shape of a calculator. You can use it to connect to your computer, to log in to Bitcoin Core, Electrum, Wasabi Wallet, BlueWallet and others. 

Or you can use the wallet to sign offline transactions. These transactions will be stored on a micro SD card (not included) which you can later plug into your computer. This way, the ColdCard never needs to be connected directly to your computer. That’s true safety!

Supplied as standard:

  • ColdCard wallet 
  • Paper to write down your 24 words
  • ColdCard sticker - nice to stick on your laptop
