A cold wallet is a vault for storing cryptocurrency that is not connected to the internet. We don’t call ChipBase as cold wallet, it’s Crypto AngPao.
The most important function of cold wallet is to store owners’ crypto long lasting, so it’s solid like Tank.
While ChipBase is on the contrary, just used occasionally to deliver greeting and value, it’s more like a vehicle of transportation such as Taxi, convenience most important.
ChipBase is secure enough with certified CC EAL 5+ level chip, the private key is generated and kept only in the chip which is isolated offline, even the manufacturers & owners can’t get it out. The private key is generated when it’a activated and the chip is attached to the device using a hardware random number generator. It is then stored on the chip, which is fully disconnected from the internet. The private key never leaves the chip. The primary purpose of the wallet is to store the private keys securely. The app is simply a user interface allowing the chips to communicate directly with the blockchain.
