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 or cold storage wallet, is a tangible object of cryptographic security principles.
Traditional hot wallets are connected to the internet and 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. However, cold storage vs. hardware wallets can differ depending on their features and third-party connectivity.
Tip ☝️
True cold storage never connects to the internet nor does it have any electronic components that need to connect to other devices (including a smartphone or computer).
