The majority of cryptocurrencies are kept inside wallets. When a user wants to create a wallet, they will first generate a pair of unique numbers and letters called private keys and public keys. The private key is like the identity of the wallet. It allows access to the wallet and allows transactions away from the wallet. Whoever holds the private key is the owner of the wallet. On the other hand, the public key generates the wallet's address that you can give to other people to send you cryptocurrency. Wallets help you create private keys, and public keys, keep track of your cryptocurrency, allow transactions, and keep your private keys secure. There are three types of wallets: Hot wallets, Hardware wallets, and Cold wallets.

these are wallets based on a mobile/PC App. They are readily accessible for free on the App store etc. When you create a wallet on these Apps, the mobile phone or the PC will store the private keys and try to keep them safe. Nonetheless, mobile phones or PCs are not secure because they always connect to the internet or other networks. The internet is full of hackers and malware that can target private keys at any time.

these are specially made devices just for keeping cryptocurrency. These devices are isolated from networks most of the time, reducing the risk of getting hacked or touched by malware. However, to make a transaction, it must be directly connected to another online device. Therefore, the hardware wallet will not stay isolated when it needs to complete a transaction, which poses risks to remote hacking or having malware installed through the connection.

As mentioned, cold wallets are air-gapped, so by themselves, they cannot connect to the blockchain and complete transactions. Without USB ports or Bluetooth connections, how does information transfer between a cold wallet and the blockchain? The answer is a QR code.

QR codes are visual information, they travel through light and cannot be hacked. Every cold wallet has a camera to scan the QR codes for receiving and sending information.

The ELLIPAL Titan cold wallet is to be used alongside the ELLIPAL Mobile APP. The APP acts as a proxy for the cold wallet to connect to the blockchain. By using the APP to scan the wallet QR codes from the cold wallet, the APP can synchronize and show you all the information about the wallet. For example: how much crypto is stored, and what is the wallet's address.

To send coins, create a transaction request on the ELLIPAL APP. The APP will create a QR code. Use the ELLIPAL Titan to scan this QR code. Once scanned, the ELLIPAL Titan knows that you want to make a transaction and approve it using the private keys stored inside. What you get is another QR code saying that this transaction has been confirmed by the private key; which will be scanned by the APP again to complete the process.

And of course, before the ELLIPAL Titan can approve this transaction for you, you must correctly input the gesture password and the account password. As you can see, the transaction process is also very secure.
