Cypherock X1

The Cypherock X1 is the flagship cold-storage wallet from India-based Cypherock, designed around a single idea: eliminate the single point of failure at the heart of every BIP39 seed phrase. Instead of writing down one 12/24-word recovery phrase, the X1 shards the secret across one X1 Vault and four tamper-proof NFC X1 Cards using Shamir-style secret sharing — any single shard reveals nothing, and you need the Vault plus one (or more) Cards to reconstruct the wallet or sign a transaction.

The bundle ships as 1 × X1 Vault + 4 × X1 Cards + USB Kit, priced at $99 for Basic (regular $129), with Standard ($179, +1-year warranty, hardcase, card sleeves) and Pro ($249, +3 years warranty, 1-year Gold plan, priority call support) tiers. A purpose-built Bitcoin-only edition ships the same hardware with a pure Bitcoin firmware. Verified users rate the device 4.9/5 across 1,640+ reviews, and the platform sits in the premium-but-affordable band alongside the Ledger Nano X and Ellipal Titan 2.0.

Security is anchored by an EAL6+ Secure Element on the Vault and a secure element on each Card, with no WiFi or Bluetooth radios anywhere in the system. The Vault communicates with the host app over USB-C and authenticates Cards over NFC tap, so a compromised computer can't reach the shards wirelessly. The companion Cypherock app manages 5,000+ coins and tokens and connects to DeFi/staking through WalletConnect, while the actual signing always happens on the Vault with shard quorum from the Cards.

The Sharded Backup Model

• No single recovery phrase — the seed is split into shards distributed across 1 X1 Vault + 4 X1 Cards using a threshold scheme; any single shard reveals nothing.
• Threshold recovery — reconstruct the wallet or sign a high-value action with the Vault plus the configured number of Cards; no need to expose all five shards at once.
• Geographic distribution — keep Cards in physically separate locations; losing one shard does not lock you out.

Hardware

• X1 Vault ($59 standalone) — USB-C device with a screen and on-device confirmation; runs the Cypherock app experience.
• X1 Cards (set of 4, $39 standalone) — tamper-proof NFC smart cards, each holding one shard; authenticate by tapping to the Vault.
• USB Kit ($10), Card Sleeves ($28), and a Hardcase ($59) available as accessories / Standard-bundle upgrades.

Software & Asset Coverage

• 5,000+ coins & tokens supported in the Cypherock app across major blockchains (Bitcoin, Ethereum, Solana, BNB Chain, Polygon, etc.).
• WalletConnect support for dApps, DeFi and staking — sign transactions without exposing your seed.
• Bitcoin-only firmware editions for purists who want a single-asset cold vault.

Tiers & Warranty

• Basic ($99) — Vault + 4 Cards + USB Kit.
• Standard ($179) — adds Hardcase, Card Sleeves, 1-year extended warranty.
• Pro ($249) — adds 3-year extended warranty, 1-year Gold plan, priority call support.

Secure Elements Everywhere

• EAL6+ Secure Element in the X1 Vault handles cryptographic operations and protects keys; each X1 Card also carries its own secure element for shard storage.
• Keys are generated and sharded entirely on-device; the full seed never exists in a single place after setup.

Wireless-Less, Air-Gapped Friendly Design

• No WiFi, no Bluetooth — the Vault cannot connect to the internet, only to the PC via USB-C.
• NFC tap signing — Cards communicate with the Vault over a short-range, local radio only; a compromised host has no way to reach the Cards remotely.

Threshold & Anti-Theft

• Threshold quorum means an attacker who steals one Card gains nothing; you can additionally configure spending limits requiring more Cards.
• Tamper-evident card design and tamper-resistant Vault casing.

Privacy

• No KYC required to set up or use the wallet; the Cypherock app is offline-first and open to WalletConnect for dApp access.

Cypherock was founded in 2019 and is based in India. The company's founding thesis is that the single 12/24-word recovery phrase — the central failure point of the whole BIP39 ecosystem — is the weakest link in self-custody. Cypherock's solution is to distribute that secret using modern cryptographic secret-sharing, combined with an EAL6+ Secure Element and a hardware UI.

The X1 is Cypherock's flagship consumer product line, sold in three tiers (Basic, Standard, Pro) and in multi-asset and Bitcoin-only firmware editions. Cypherock publishes reproducible builds, runs responsible-disclosure bounties, and is often recommended by the Indian and global cypherpunk community as a non-custodial alternative to seed-phrase-based wallets. The company reports a 4.9/5 rating from 1,640+ verified buyers and ships worldwide from cypherock.com.
