In today’s digital realm, securing crypto assets is paramount. Enter the cold wallet card—an offline sanctuary for digital wealth.

What is a cold wallet card?

A cold wallet card, also known as a hardware wallet or cold storage wallet, it’s a tangible manifestation of cryptographic security principles. Traditional hot wallets are connected to the internet and they are also exposed to hacking and online threats, however, cold wallet cards operate in an offline environment, reducing the risk of unauthorized access and theft.  

At its core, a cold wallet card looks like a smart card or metal plate, featuring either a secure chip or engraved private keys stored directly on the device. These private keys are generated and securely stored within the device itself, making sure that they never come into contact with potentially compromised networks or devices.

Typically, the term “cold card wallet” is used interchangeably with hardware wallets shaped like a card.
