What is COLDCARD?

Physical Security measures are enhanced through the use of a specialized chip that protects your secret seed words and ensures that sensitive information is securely stored. The software is open source, giving users the flexibility to compile it independently if desired. This hardware wallet uniquely allows for a completely offline experience, supporting all processes from seed generation to the approval of transactions without needing an internet connection. It features native support for PSBT (BIP174), which significantly boosts its usability. With a full-sized numeric keypad, entering your PIN is made easy and efficient. The design is minimalistic and straightforward, avoiding excessive packaging with unnecessary boxes or cables. A vibrant 128x64 pixel OLED display shows all crucial transaction information clearly. To keep your private key secure, a dedicated crypto security chip is employed, isolating it from the main microcontroller's flash storage. Proudly crafted in Toronto, Canada, it boasts a reliable supply chain, reinforced by a tamper-evident bag that is numbered, with this information logged within the device. Moreover, it includes an integrated MicroSD card slot for backup and data storage, allowing for completely offline transaction signing through sneakernet, which ensures that your crypto assets are well-protected and remain out of reach from potential threats. This combination of features makes it an exceptional choice for anyone prioritizing security in their cryptocurrency transactions.
