Cold Storage Wallet

Information stored online can be copied & stolen. Online exchanges and wallet providers can disappear, go offline, be hacked. They are not reliable.

G999 Card hardware wallet is a cryptocurrency wallet that stores the user's private keys (critical piece of information used to authorize outgoing transactions on the blockchain network) in a secure hardware device. The main principle behind hardware wallets is to provide full isolation between the private keys and your easy-to-hack computer or smartphone. Thanks to our integrated secure chip on the card, the information is privately stored.

At G999 we are developing hardware wallet technology that provides the highest level of security for crypto assets. Our products combine a Secure Element and a proprietary OS designed specifically to protect your assets. The G999 hardware wallets empower you with the ownership and control of your private keys.

G999 Card
Saving Storage Wallet

Usually, a savings account is a bank account where you store money and earn interest on that money. You're earning interest because the bank is using your funds to loan money to other people. But are your assets safe enough? In an economical environment, where the banks are paying only negative interest, and the accounts can be frozen at any moment, are you sure you want to continue classically?

With the G999 card, we created the most secure savings account, the one you own, you control, and you can decide what to do with your funds. Is it enough just to set up a specific date and time for your wallet and the private key will be securely stored and only shared with you at the chosen time. If you change your mind and you want to access the funds, you can still do it, as you are always the owner of the 24 words seed.

The reinvented way to save assets for your future, for a great event in your life, for yourself!
