What is a hardware wallet?

A hardware wallet is a physical device that stores your cryptocurrency private keys in a secure offline environment. This makes it much more difficult for hackers to access your funds, as they would need to physically steal your device in order to do so.

What are the benefits of using a hardware wallet?

There are many benefits to using a hardware wallet, including:
  • Increased security: Hardware wallets offer much higher security than other types of cryptocurrency wallets, such as software wallets or online wallets.
  • Offline storage: Your private keys are stored offline on the hardware wallet, which means they are not accessible to any internet-connected devices. This makes it much more difficult for hackers to steal your funds.
  • Support for multiple cryptocurrencies: KEYRING HARD WALLET supports 04 different chains, so you can store all of your coins in one place.
  • Easy to use: Just tap the card on the back of your mobile device to use.

How do I keep my backup card safe?

There are a few things you can do to keep your backup card safe:
  • Store your card in a safe place where it cannot be easily stolen;
  • Keep your PIN code memorizable;
  • Don't extract the encrypted Private Key or insert it on random wallets;
  • Keep your card in a dry and cool place to avoid damage.

What if I lose my cards?

If you only lose your main card, you can use your backup card to replace it. However, we highly recommend you to extract your Private Key and keep it in a secure location in this case, since you have no backup left.
If you lose both of the cards, it's most likely you will lose access to your funds permanently. As a reason, your Private Key is only stored locally on your two cards, where no one can reach it, including our team.
It's best to keep your cards separately in dry, cool, and secure places, especially with your backup card.
