Most users store the private key (seed phrase) off-device. The Specter DIY Air-Gapped communicates via QR codes. Furthermore, the hardware wallet's code is completely open source and optimized for Bitcoin.
A smartphone-sized display makes it easy to navigate and type in Bitcoin seed words. This process is further simplified by the SD card and seed QR option.
Get the enhanced version of the Specter DIY, the Specter Shield. It features additional interchangeable secure elements for extremely secure encryption of the Bitcoin seed phrase and a rechargeable battery.
Instead of everything happening silently in the background like with most other hardware wallets, the Specter DIY lets you transparently track what the hardware wallet is doing. The large, clear display offers a wealth of information that wouldn't fit on the small screens of other hardware wallets.
Since the seed phrase is not stored on the Specter DIY, you can also use the hardware wallet to create secure cold storage for friends or family members.
