🧊 What Is CoolWallet?

CoolWallet is a credit-card-sized hardware wallet developed by CoolBitX. It connects to your phone via encrypted Bluetooth and stores cryptocurrency private keys offline inside a secure element chip (EAL5+ or EAL6+), offering high security while being extremely portable. It requires biometric confirmation on your phone, a screen check on the wallet itself, and a physical button press for every transaction.
