About Coolwallet
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.
