As a quick breakdown, hot wallet refers to the real-time network wallet, which allows easy and quick transaction. Cold wallets, on another hand, are designed for maintaining the complete safety of VSYS Coins and are therefore disconnected from the network. They are only opened when signatures are granted. A hot wallet is connected to the network in real time, which is convenient for users to carry out various actions in a quick manner, including coin transfer, coin collection, coin leasing, and participation in airdrops. Apart from that, hot wallet is the only medium to initiate the operation of cold wallet. In other words, a cold wallet must be associated or connected to a hot wallet in order for any actions to be performed in the cold wallet, such as managing and viewing coins. A cold wallet is disconnected from the network at all times, except when a signature is presented, by which users can then perform different actions to the cold wallet through the hot wallet. That is, if a user wishes to operate commands to a cold wallet through the hot wallet interface, a cold wallet-generated private key signature is required by the blockchain. It is strongly advised that the cold wallet private key and keywords that generate private keys are kept secure, so that signatures cannot be forged by unauthorized parties, and VSYS Coins can remain absolutely safe. A friendly reminder to users who own a large amount of VSYS Coins that cold wallets are suggested for storage as they ensure a high level of security. Hot wallet and cold wallet are two separate wallets, each with a set of private key and public key. To make viewing and operation easier, users can connect a cold wallet to a hot wallet through the hot wallet interface. By “connecting”, it does not imply that the cold wallet is linked to the network, cold wallets therefore still remain safe.
