⑤ How do cold wallets and mnemonic hardware work

Different from hardware cold wallets, software cold wallets use pure software to implement the cold wallet function.

Notes on using cold wallets:
1. 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. Because the mnemonic you get may not be random, it may be pre-generated, or it may be pseudo-random. Hardware cold wallets cannot prove to users that they are safe at this point. Our continued use of hardware wallets is based on trust in the hardware manufacturer, which is vulnerable in the world of digital currencies. Software cold wallets can provide proof.
2. When using the software cold wallet, you can choose to trust the software and let it help you generate mnemonic phrases. You can also choose not to trust the software and generate mnemonics elsewhere by yourself. Then generate a cold wallet by offline import. Because the device of the cold wallet is permanently offline, there is no possibility to transmit data to the Internet (the only interaction is to scan the QR code and observe the plaintext transmission between the wallets, which can be reviewed), so the security of the mnemonic is absolutely guaranteed. guarantee. Therefore, the security of the mnemonic of the software cold wallet is higher than that of the hardware cold wallet.
3. Hardware cold wallets cannot prove to users that they are safe at this point.
