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 Copperhead?

Copperhead serves as a collaborative open-source AI platform designed to support hardware teams in the intricate tasks of circuit board design, validation, and production. Users can effortlessly initiate the process by providing a description of a modification or a product brief, prompting the AI to accurately edit existing KiCad files, update associated documentation, and execute KiCad's built-in validation checks until they all succeed. The thorough workflow includes multiple stages such as outlining specifications, defining architecture, selecting components, designing schematics, creating layouts, generating outputs, developing firmware, and establishing a development strategy, ensuring that each step yields a concrete artifact saved on disk before moving forward. Validation gates assess various factors including adherence to budget, analysis of logical subsystems, component numbers backed by datasheets, compliance with ERC standards in schematics, DRC-compliant layouts, generation of Gerber files, firmware source code preparation, and detailed bring-up plans. Furthermore, Copperhead can accommodate changes to pre-existing boards; users can point it to a KiCad repository, initiate the project, and request particular modifications. The adjustments made are specifically targeted at the KiCad source files, ensuring they are minimal and easily reviewable, while preserving the integrity of other sections. This efficient methodology facilitates a smooth revision process that significantly reduces potential disruptions to the overall project timeline, ultimately enhancing the productivity of hardware teams.
