IV How does cold wallet and mnemonic hardware work

Increase flexibility with trusted mnemonics.
Software cold wallet, different from hardware cold wallet, software cold wallet uses pure software to realize the function of cold wallet. Users need to use two mobile phones, one of which is permanently offline, as a cold wallet to store the private key (mnemonic phrase). The other is connected to the Internet and used as an observation wallet. Software cold wallets and hardware cold wallets achieve the same functions and have similar security levels. But they have some notable differences: software cold wallets can use idle mobile phones without additional hardware; hardware cold wallets transmit data via a data cable or Bluetooth, while software cold wallets scan QR codes.
Trusted mnemonics: Software cold wallets can achieve more thorough trustlessness (that is, no need to trust software developers), and users can prove the absolute security of their wallets by themselves. In asset safety, the first and foremost is the safety of mnemonic phrases. In the security of mnemonics, the first confirmation is the randomness of mnemonic generation. If you’re using a hardware wallet from a malicious hardware vendor (or buggy), you’ve probably fallen for the first step.
When using a software cold wallet, you can choose to trust the software to help you generate mnemonics. You can also choose not to trust the software and generate mnemonics elsewhere by yourself. Therefore, the security of the mnemonic of the software cold wallet is higher than that of the hardware cold wallet.
Software cold wallets are more flexible than hardware cold wallets. Usually software cold wallets can implement more complex functions than hardware cold wallets. The flexibility of the software cold wallet also makes it more advantageous in asset recovery. If your hardware wallet is damaged, you need to buy hardware (same manufacturer) for hardware recovery. With software cold wallets, there is no such concern.
