“Cold wallet” refers to a wallet product that stores private keys of digital assets and never connects to the Internet. Sallet one cold wallet is a hardware wallet, which is used to generate mnemonic words randomly, and private keys of different currencies are generated from the mnemonic words. In the end, the private key generates the public key, and finally the public key generates the asset address to realize the safe storage of digital assets.

Code and Reproducibility
We were able to locate Sallet One’s GitHub repository but it lacks build instructions. Together with the lack of actual product pictures or videos, the code being only two commits, the companion apps not having many users/ratings and the rather lacking documentation we have little hope for this product to be very interesting but for now simply consider it as not verifiable.
Do your own research
In addition to reading our analysis, it is important to do your own checks. Before transferring any bitcoin to your wallet, look up reviews for the wallet you want to use. They should be easy to find. If they aren't, that itself is a reason to be extra careful.
