What is Keystone Wallet?

By utilizing QR code transmissions, we have successfully mitigated the risks associated with malware infiltration. This innovative approach enables a level of transparency that surpasses what is achievable through Bluetooth or USB connections. To ensure the integrity of every transmission that interacts with the Keystone, it is crucial to explore the verification process. The proprietary Secure Element, which adheres to bank-grade security standards, guarantees that your private keys are always safeguarded within the Keystone. It generates a truly random number to protect your private key, ensuring that your cryptocurrency assets are maintained in the highest security possible. Additionally, we provide open-source firmware that complies with BIP32, BIP39, and BIP44 standards. Keystone has set the industry standard by introducing the first open-source Secure Element firmware for hardware wallets. This allows users to verify how their private keys are derived from physically generated entropy (TRNG), which is securely confined within the Secure Element. Furthermore, we offer open-source resources such as the hardware wallet application layer, device schematic, and bill of materials (BOM), enabling complete transparency and trust in our technology. By fostering an open-source environment, we empower users to have full control and insight into their security mechanisms.

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.
