COLDCARD Description

Physical Security. Your secret seed words are safeguarded within a specialized chip that ensures secure storage of sensitive information. The entire codebase is open source, allowing you to compile it independently. It is the only hardware wallet that offers the option of remaining completely offline, enabling full functionality from seed creation to transaction approval. It natively supports PSBT (BIP174) for enhanced usability! Featuring a full-sized numeric keypad, entering your PIN is both straightforward and efficient. The packaging is minimalistic, with a plain design that avoids unnecessary boxes and cables. It has a vibrant 128x64 pixel OLED display that presents all essential transaction details. A genuine crypto security chip is utilized to keep your private key in a secure location, separate from the main microcontroller's flash storage. Crafted with care in Toronto, Canada, it comes with a secure supply chain, verified by a tamper-evident, numbered bag, with the bag number documented within the device. Additionally, an integrated MicroSD card slot allows for backup and data storage, facilitating completely offline signing by transferring unsigned and signed transactions via sneakernet, ensuring your crypto assets remain safe and sound.
