Cypherock X1 Cypherock X1
A plan byCypherock X1
The Cypherock X1, from India's Cypherock, removes the classic weak point of cold wallets: the paper seed phrase. The private key is never stored whole; it is cryptographically split into 5 parts using Shamir Secret Sharing, spread across the device (X1 Vault) and four NFC smartcards (X1 Cards). Any one card plus the vault is enough to access funds: no single object holds the complete key, and losing one card does not compromise the wallet. The smartcards carry an EAL6+-certified secure element, the same level as bank cards. It is open-source, works offline (verification on a dedicated chip) and claims support for over 18,000 assets. The vault connects over USB-C, the cards over NFC. Indicative retail price around $199 (~€185): the store loads prices via JavaScript and they could not be read automatically, so the figure is flagged as partial.

Verdict
Score 4.2/5, very strong profile. In its favour: no seed phrase: key split into 5 with Shamir Secret Sharing across vault + 4 NFC smartcards; EAL6+ secure element; open-source; offline operation; very broad multi-asset support (18,000+). The trade-off to weigh: multi-object model (vault + 4 cards) that must be stored and distributed thoughtfully: the convenience demands careful physical management; price not confirmed on the store (loaded via JavaScript); young company with a shorter track record than legacy brands.
On the Sovereignty lens the score is 4.9/5 (outstanding): the strength is fund control (5.0/5), while censorship resistance (4.8/5) is the weak link.
