To add a little sparkle to the management of its cryptocurrencies, the maker QT31416 has designed a real physical wallet, whose structure, designed and printed in 3D, welcomes inside a Raspberry Pi Zero WH. It is certainly a more fun and creative solution than buying a ready-to-use wallet, which could also be seen by various users as an opportunity to approach the world of cryptocurrencies and the development of the first projects with the Raspberry Pi at the same time. , as well as design and 3D printing.
Obviously the biggest doubt concerns the security of this wallet: a comparison with those offered by Trezor, one of the most active companies in the development of real and own cryptocurrency wallets. If this company provides ultrasound-sealed hardware inside the cryptocurrency case and storage not locally, the Raspberry needs an SD card to be able to store virtual currency. In this regard, the developer suggests setting a password for the card used in order to prevent unwanted people from accessing it.
