#2 on the leaderboard Hardware Self-custody

Cypherock X1

Cypherock

A hardware wallet that splits your seed across 5 NFC cards. Lose any 4, still recover. No single point of failure.

The verdict

The most interesting hardware wallet launched in the last 3 years. The split-key model is genuinely novel. Ecosystem is still catching up.

/ Pros
  • +Most novel backup model in the category: Shamir-style 2-of-5 across NFC cards
  • +Fully open source. EAL6+ secure element.
  • +No single card compromise = no fund loss. Even if the vault is stolen, your funds are safe.
  • +Genuine innovation in a category that mostly copies each other
/ Cons
  • More expensive than Tangem or Trezor
  • Smaller ecosystem. dApp support is maturing.
  • You must keep 4 of 5 cards safe — losing more is unrecoverable
  • Companion app (cySync) is functional but rough around the edges
/ Best for & not for
Best for

High-net-worth holders who want the strongest possible backup story and are willing to manage 5 cards.

Not for

Casual users, anyone who doesn't want to think about backup distribution.
