Solid Security with Great Potential, but Needs Critical Updates!
Overall, I am very satisfied with the Cypherock X1. The Pros: Superior Security: The use of Shamir Secret Sharing with the device and four backup cards is a brilliant security approach. Design & Utility: The sleek, non-obvious design is excellent, and the ability to hold up to four seeds is highly practical. Flexibility: It can function as a standalone backup device and supports a dedicated BTC-only firmware option. Inheritance: I really like their inheritance plans, which offer a great solution for long-term estate management. The Cons & Critical Security Concerns: Major Security "No-Go" (Inheritance Plan): Regarding their inheritance feature, you currently have to type your passphrase into their software rather than on the device itself. This is a massive security risk and an absolute no-go for me. App Limitations: The Android app interface feels outdated compared to competitors, and currently, it only supports receiving—not sending. Hardware Interaction: The small screen and joystick input make typing long passphrases cumbersome, potentially discouraging users from using them. Asset Support: It does not support as wide a range of altcoins as other wallets. Conclusion: I really like the product and its security-first philosophy, but the way passphrases are handled within the inheritance plan is a critical flaw that needs to be fixed. I hope future versions bring a more modern user experience and address these vital security and interface concerns.
