Specter DIY
Cold Storage
Specter DIY is a fully open-source, air-gapped Bitcoin signing device that users build themselves from commodity hardware (STM32 development boards), making it one of the most transparent and verifiable cold storage solutions available. The device communicates exclusively via QR codes, requires no USB data connection, and is designed to work with Specter Desktop and other PSBT-compatible wallet coordinators. Because the hardware is generic and off-the-shelf, users can independently verify every component of the signing device.
