What is it for?
Coolwallet S is a digital wallet whose role is to protect your cryptocurrencies. Keeping your crypto-currencies safe is an issue for crypto-currency users. While it is possible to leave your crypto-currencies on exchange platforms for example, it is always better to keep your private key. To do this, there is nothing better than holding a physical digital wallet, commonly known as a hardware wallet.
Coolwallet is a consumer hardware wallet that is easy to use without compromising on security.
CoolBitX Technology Ltd (CBX) is a Taiwanese company focused on security issues related to blockchains. Founded in 2014 by Michael Ou and backed by heavyweight investors in the cryptocurrency sector such as Bitmain, CoolBitX specialised in the design of US-patented digital wallets.
In 2018, after several years of R&D, CBX released the Coolwallets S, the first cryptocurrency hardwallet in the shape of a credit card.
