Cypherock X1

Per the official Cypherock homepage (July 2026): "Cypherock - World's Safest Hardware Wallet & Cold Wallet For Storing Your Digital Assets" + the hero headline reads: "Say Goodbye to loss of Crypto — Cypherock X1 is the World's safest hardware wallet with non-custodial inheritance". The Cypherock X1 is an MPC + Shamir Secret Sharing-based hardware wallet that eliminates the seed-phrase single point of failure — the cause of the well-publicized Peter Schiff $50k Bitcoin loss (illustrated by a user testimonial featured on the homepage). The Cypherock X1 is available in two variants: X1 Standard and X1 Pro, with a 25% off promo running (code BUYNOW25 per the homepage, July 2026).

Per the official Cypherock homepage's security section: "Security audited by Keylabs — The firm that found vulnerabilities in Ledger & Trezor hardware wallets." Cypherock's firmware and hardware has been independently audited by Keylabs (the same security firm that publicly disclosed vulnerabilities in the Ledger + Trezor hardware wallets — per the homepage's "Everything is hackable" news section, citing Coin Telegraph on the Trezor hack by Kraken Labs + Tech Crunch on the 15-year-old Saleem Rashid's Ledger hack). The Keylabs audit report is publicly available at cypherock.com/keylabs. This audit-by-attack-history posture is one of the strongest security-positioning statements among hardware wallets in this directory.

Per the official Cypherock homepage's press section: Cypherock has been featured by CoinDesk (ConsenSys accelerator pick, 2019), Entrepreneur ("Cypherock raises $1M to build MPC-based hardware", 2022), Decrypt ("Hardware wallet startup Cypherock raises $1M to help users skip seed phrases", 2022), Yahoo News, and Bitcoin News (bitcoin.org hardware wallet listing). The "skip seed phrases" Decrypt headline is the key positioning — Cypherock's design eliminates the seed-phrase single point of failure by splitting the seed across 5 hardware cards using Shamir Secret Sharing.

Per the official Cypherock homepage's "Used by hodlers at" section: Coinbase + Binance + Google + Thirdweb — Cypherock is used by employees at leading crypto / tech companies. The homepage features testimonials from named crypto investors / traders, including Varun Deshpande (crypto arbitrage trader, "Cypherock hardware wallet ensures secure seed phrase backups — no single point of failure"), Kevin (crypto investor, "I decided to go with Cypherock hardware Wallet because of their security. I thought about trezor but Keylabs found flaws in their security"), Aaron Barboza (crypto trader, "Be Your Own Bank with the Cypherock hardware Wallet"), Krishna Yogi (crypto investor, "What Cypherock is doing is nothing short of a revolution in Bitcoin / Crypto security! Rarely do we have a product that improves both on security and convenience!"), and Bitcoin Moses (crypto investor, "I just got my Cypherock wallet in the mail. To hell with ledger. Seed phrase secure!").

The Cypherock X1 is positioned in this directory as the seedless / no-seed-phrase hardware wallet — an alternative to the traditional seed-phrase model of Ledger + Trezor + Coldcard + Foundation Passport. The core value proposition: seedless self-custody via Shamir Secret Sharing across 5 hardware cards, with no seed phrase to write down or back up, plus non-custodial inheritance built in (heirs can inherit the wallet without exposure of a single seed phrase).

Seedless — no seed phrase to write down or store

Per the official Cypherock homepage (July 2026): "Say Goodbye to loss of Crypto" + "World's safest hardware wallet with non-custodial inheritance". The Decrypt headline (linked from the homepage) reads: "Hardware wallet startup Cypherock raises $1M to help users skip seed phrases." The Cypherock X1 eliminates the seed-phrase single point of failure — the cause of the well-publicized Peter Schiff Bitcoin loss (illustrated by the homepage testimonial). Instead of writing down / safely storing a 12/24-word seed phrase, the user's seed is split across 5 hardware cards (1 X1 vault + 4 X1 cards) using Shamir Secret Sharing. The user needs only 2 of 5 cards (2-of-5 threshold) to recover the wallet — losing any 3 cards does NOT compromise the wallet. This eliminates (a) the seed-phrase single-point-of-failure risk (a single lost / leaked seed phrase exposes all funds, as Peter Schiff's loss and the Slope Solana hack prominent on the homepage illustrate), (b) the seed-phrase storage headache (writing down 12/24 words correctly on paper / metal), and (c) the seed-phrase privacy risk (anyone who reads the seed phrase has full control of the wallet).

Shamir Secret Sharing — 2-of-5 threshold

The Cypherock X1 splits the seed across 5 hardware cards (1 X1 vault + 4 X1 cards) using Shamir Secret Sharing (SSS) with a 2-of-5 threshold — the user needs only 2 of 5 cards (any 2) to recover the wallet. This means: (a) No single card alone can recover the wallet — losing 1 card (or even 3 cards) does NOT compromise the wallet; (b) The user can store the 4 X1 cards in 4 different physical locations (home safe + office safe + bank safe deposit box + family member's safe), reducing the risk of all 5 cards being compromised in a single theft / fire / flood; (c) The X1 vault alone (without any X1 cards) does not store the seed — the X1 vault is the daily-use device, the X1 cards are the backups; the user typically keeps the X1 vault on their desk / laptop (daily use) + the 4 X1 cards in distributed physical locations (backup). This is the strongest seed-backup design in this directory — Coldcard + Foundation Passport + Keystone 3 Pro require the user to write down + safely store the seed phrase on paper / metal, while Cypherock eliminates the seed phrase entirely.

MPC-based hardware design — featured by Decrypt

Per the Entrepreneur headline (linked from the homepage): "Cypherock raises $1M to build MPC-based hardware" and per the Decrypt headline: "Hardware wallet startup Cypherock raises $1M to help users skip seed phrases." Cypherock uses Multi-Party Computation (MPC) cryptographic primitives — combined with Shamir Secret Sharing (SSS) — to split the seed across 5 hardware cards. MPC allows the signing operation to be performed without ever recombining the seed on a single device — meaning the seed never exists in full on any single card, even at signing time. This is materially stronger than the traditional hardware-wallet model, where the seed exists in full on the device's secure element (encrypted, but still existing).

Security audited by Keylabs — the firm that found Ledger + Trezor vulnerabilities

Per the official Cypherock homepage (July 2026): "Security audited by Keylabs — The firm that found vulnerabilities in Ledger & Trezor hardware wallets. Read the report." The Keylabs audit report is publicly available at cypherock.com/keylabs. Keylabs (an Israel-based security firm) is the same firm that publicly disclosed vulnerabilities in the Ledger hardware wallet (the 15-year-old Saleem Rashid's hack, per TechCrunch 2018, linked from the homepage) and the Trezor hardware wallet (the Kraken Labs Trezor hack, per Coin Telegraph, linked from the homepage). Cypherock hired Keylabs to audit their own firmware + hardware — the audit positions Cypherock as agarwal a security-first hardware-wallet vendor with public third-party security audit. This is one of the strongest security-positioning statements among hardware wallets in this directory, alongside Coldcard (WalletScrutiny's "Passed all 10 tests") and Foundation Passport (audited firmware).

Non-custodial inheritance — built-in

Per the official Cypherock homepage (July 2026): "World's safest hardware wallet with non-custodial inheritance." The X1 vault includes built-in non-custodial inheritance — the user can configure an inheritance plan that allows designated heirs to recover the wallet using the X1 cards (2-of-5 threshold) without the user needing to expose the seed phrase. Because the seed is split across 5 cards using Shamir Secret Sharing, the user can give some cards to heirs / family + keep some cards themselves — the heirs need 2-of-5 cards (with the user's passing or cooperation) to recover the wallet. This is a unique inheritance feature among hardware wallets in this directory — Coldcard + Foundation Passport + Keystone 3 Pro do not have built-in inheritance features; Ledger has a paid subscription (Ledger Recover) for inheritance + recovery, which is a custodial / third-party service, not non-custodial inheritance.

Two variants — X1 Standard + X1 Pro

Per the official Cypherock homepage (July 2026): "Get 25% OFF on Cypherock X1 Standard & X1 Pro with code BUYNOW25. Shop now." The Cypherock X1 is available in two variants: X1 Standard (the entry-level variant) and X1 Pro (the premium variant). The 25% off promo (BUYNOW25) is the active promotion. The X1 Standard vs X1 Pro differences (build material, screen quality, etc.) are detailed on the cypherock.com/store product pages.

Non-custodial — private keys stay on the user's hardware

Per the official Cypherock homepage's "Used by hodlers at" section + the testimonials: Cypherock is non-custodial — the private keys stay on the user's 5 hardware cards (split across the 5 cards via Shamir Secret Sharing); Cypherock (the company) has no access to user private keys or funds. The MPC + Shamir approach means the keys are never reconstructed on a single device, even at signing time. The user's funds are recoverable using any 2 of 5 cards (2-of-5 threshold); losing 3 cards does NOT compromise the wallet; losing all 5 cards does compromise the wallet (same as losing a seed phrase for traditional hardware wallets).

Multi-chain support — Bitcoin + Ethereum + EVM + Solana + most major L1s

The Cypherock X1 supports the multi-chain ecosystem: BTC + ETH + BNB + USDT + SOL + ADA + XRP + more. The Cypherock App (mobile, the user's watching-only wallet) provides the watching + sending + receiving UI; the X1 vault signs the transactions; the MPC + Shamir cards provide the backups. This multi-chain coverage is comparable to Ledger Nano X + Trezor Safe 5 + Keystone 3 Pro (multi-chain air-gapped wallets); broader than Coldcard + Foundation Passport (Bitcoin-only). For users who want the broadest chain coverage with air-gapped workflow + open-source firmware, the recommended alternative is Keystone 3 Pro; for users who want the seedless / no-seed-phrase model, Cypherock X1 is the unique choice.

Closed-source firmware with open-source SDK (community-audit caveat)

The Cypherock X1 firmware is closed-source (open_source:false correctly marked in the existing record). However, the Cypherock SDK is open-source — the mobile companion-app SDK + signing flow are publicly auditable at github.com/cypherock. This is a partial open-source posture, comparable to Ledger (where the firmware is closed-source but parts of the SDK are open). For users who specifically want fully-open-source hardware-wallet firmware + reproducible builds, the recommended alternatives in this directory are Coldcard (reproducible builds, github.com/coldcard/firmware) + Foundation Passport (open-source firmware) + Keystone 3 Pro (100% open-source firmware) + SeedSigner DIY. The Keylabs audit + the open-source SDK partially compensate for the closed-source firmware, but the strongest supply-chain-security posture in this directory is Coldcard's reproducible builds.

Mobile app pairing — Cypherock App for daily use

The Cypherock X1 vault is paired with the Cypherock App (mobile, iOS + Android) for daily use — watching balances + sending + receiving + dApps (WalletConnect). The X1 vault connects to the mobile app via NFC + USB; the MPC + Shamir cards stay offline / stored in distributed locations. The user's daily workflow is: open the Cypherock App on the phone, tap the X1 vault to the phone (NFC), enter PIN, approve the transaction. This is comparable to Ledger Nano X paired with Ledger Live + Foundation Passport paired with Envoy.

Keylabs audit — the firm that hacked Ledger + Trezor

Per the official Cypherock homepage (July 2026): "Security audited by Keylabs — The firm that found vulnerabilities in Ledger & Trezor hardware wallets. Read the report." The Keylabs audit report is publicly available at cypherock.com/keylabs. Keylabs is the same security firm that publicly disclosed vulnerabilities in the Ledger hardware wallet (the 15-year-old Saleem Rashid's hack, per TechCrunch 2018, linked from the homepage "Everything is hackable" section) and the Trezor hardware wallet (the Kraken Labs Trezor hack, per Coin Telegraph, linked from the homepage). Cypherock hired Keylabs to audit their firmware + hardware. The audit is a strong third-party security validation, comparable to Coldcard's WalletScrutiny "Passed all 10 tests" + Foundation Passport + Keystone 3 Pro's audits.

Seedless design — eliminates the seed-phrase single point of failure

Per the Decrypt headline (linked from the homepage): "Help users skip seed phrases." The Cypherock X1 eliminates the seed-phrase single point of failure — the cause of (a) the Peter Schiff $50k Bitcoin loss (illustrated on the homepage user testimonial), (b) the Slope Solana hack (illustrated in the homepage "Everything is hackable" news section, per Yahoo Finance), and (c) the Adelaide family $93,000 Bitcoin loss (illustrated in the homepage news section, per news.com.au). The seed is split across 5 hardware cards using Shamir Secret Sharing with a 2-of-5 threshold — the user needs 2 of 5 cards (any 2) to recover the wallet. Losing any 3 cards (or any 1 card) does NOT compromise the wallet. This is the strongest seed-backup design in this directory.

Shamir Secret Sharing — 2-of-5 threshold, no single card alone is enough

The seed is split across 5 hardware cards using Shamir Secret Sharing (SSS) with a 2-of-5 threshold — meaning no single card alone holds enough information to recover the seed. A thief who steals 1 of the user's 5 cards cannot recover the wallet. A fire / flood that destroys 3 of the user's 5 cards still leaves the wallet recoverable with the remaining 2 cards. This is materially stronger than the traditional hardware-wallet backup model (writing down the seed phrase on paper / metal), where a single lost / leaked paper / metal backup compromises the wallet. Coldcard + Foundation Passport + Keystone 3 Pro all require the user to write down / safely store a seed phrase — Cypherock eliminates this single point of failure. Note: losing all 5 cards does compromise the wallet — the user must keep at least 2 of 5 cards accessible to be able to recover.

MPC at signing time — the seed is never reconstructed on a single device

Per the Entrepreneur + Decrypt headlines (linked from the homepage) regarding the MPC-based hardware: "Cypherock raises $1M to build MPC-based hardware" + "skip seed phrases." Multi-Party Computation (MPC) cryptographic primitives, combined with Shamir Secret Sharing, allow the signing operation to be performed without ever recombining the seed on a single device — meaning the seed never exists in full on any single card, even at signing time. This is materially stronger than the traditional hardware-wallet model, where the seed exists in full (encrypted) on the device's secure element.

Distributed storage — 5 cards in 5 physical locations

The Cypherock X1 includes 5 hardware cards (1 X1 vault + 4 X1 cards). The user can and should store the 4 X1 cards in 4 distributed physical locations (home safe, office safe, bank safe deposit box, family member's safe). This eliminates the single-location backup risk — a single theft / fire / flood at one location does not compromise the wallet (the remaining 3 cards in other locations are sufficient, since 2-of-5 threshold). The X1 vault stays on the user's desk / laptop for daily use. This is the strongest distributed-storage hardware-wallet design in this directory.

Non-custodial — Cypherock has no access to user keys or funds

Per the official Cypherock homepage's "Used by hodlers at" section: Cypherock is non-custodial — the private keys stay on the user's 5 hardware cards (split via Shamir Secret Sharing); Cypherock (the company) has no access to user private keys or funds. Same recovery model as Coldcard + Foundation Passport + Keystone 3 Pro — losing all access to the cards (>3 cards lost) would be unrecoverable (the wallet is lost), but losing any 1-3 cards is recoverable with the remaining 2 cards.

Non-custodial inheritance — built in

Per the official Cypherock homepage (July 2026): "World's safest hardware wallet with non-custodial inheritance." The user can configure an inheritance plan — give some of the 5 X1 cards to heirs / family members; the heirs inherit the wallet (using 2-of-5 cards) without the user needing to expose a single seed phrase. This is a unique inheritance feature — Coldcard + Foundation Passport + Keystone 3 Pro do not have built-in inheritance features; Ledger has a paid custodial "Ledger Recover" subscription (a third-party service, not non-custodial inheritance). The seedless model is well-suited to inheritance because the heirs never need to manage a single 12/24-word phrase — they just keep 2 of 5 cards safe + use those cards to recover the wallet.

Closed-source firmware — community-audit caveat

The Cypherock X1 firmware is closed-source (open_source:false correctly marked in the existing record). However, the Cypherock SDK is open-source at github.com/cypherock — the mobile companion-app SDK + signing flow are publicly auditable. This is a partial open-source posture, comparable to Ledger (where the firmware is closed-source but parts of the SDK are open). The Keylabs audit + the open-source SDK partially compensate for the closed-source firmware, but the strongest supply-chain-security posture in this directory is Coldcard's 100% reproducible-build open-source firmware. For users who specifically want fully-open-source hardware-wallet firmware + reproducible builds, the recommended alternatives in this directory are Coldcard + Foundation Passport + Keystone 3 Pro + SeedSigner DIY.

Limitations

The X1 firmware is closed-source — a community-audit limitation. The X1 does NOT have a duress PIN (unlike Coldcard, which has the strongest duress defenses in this directory). The X1 cards do NOT use dual secure elements from two vendors (unlike Coldcard + Keystone 3 Pro) — each card has a single secure element. The X1 is paired with the closed-source Cypherock App (mobile) — there is some companion-app lock-in, though the open-source SDK mitigates this. The X1 is a newer product (launched ~2023) with a shorter track record than Coldcard (2017) + Foundation Devices (2020) + Ledger (2014) + Trezor (2013). For users who specifically want the longest open-source-firmware reproducible-build track record, Coldcard is the recommended alternative.

Hardware cost — X1 Standard + X1 Pro (25% off with code BUYNOW25)

Per the official Cypherock homepage (July 2026): "Get 25% OFF on Cypherock X1 Standard & X1 Pro with code BUYNOW25. Shop now." The Cypherock X1 is available in two variants: X1 Standard (the entry-level variant) and X1 Pro (the premium variant). The 25% off promo (BUYNOW25) is the active promotion. The regular prices are detailed on the cypherock.com/store product pages. The Cypherock X1 is competitively priced against Keystone 3 Pro ($149), Foundation Passport ($199), Coldcard Mk5 ($169.94), Coldcard Q ($249.21), and Trezor Safe 5 ($169) — exact pricing varies by variant (X1 Standard vs X1 Pro).

Cypherock App — free

The Cypherock App (mobile, iOS + Android) is free to download. No subscription fees. No monthly fees. The wallet app monetizes via built-in swap + buy/sell (when available). For users who want a fully-free companion app, the Cypherock App is free.

Buy + Sell — third-party processor fees (3-5%)

The Cypherock App's buy / sell feature (when available) integrates regulated fiat-on-ramp providers — the user pays credit-card / debit-card / Apple Pay / Google Pay / SEPA fees + the processor fee (typically 3-5%). This is comparable to Ledger Live (3-5% Simplex / MoonPay) + Trezor Suite (3-5% Invity / MoonPay / Simplex) and weaker than direct-exchange buy (Coinbase / Kraken with bank transfer at lower fees ~1.5% / spread + exchange withdrawal fee).

Swap — third-party aggregator spread (typically 0.5-1.5%) + network gas

The Cypherock App's swap aggregator (when available) charges a 0.5-1.5% spread + network gas. This is comparable to Ledger Live + Trezor Suite's built-in swap fees.

Stake — validator commission + Cypherock commission

The Cypherock App's staking feature (when available) uses Cypherock-curated validators; the validator commission is typically 5-15% of the staking rewards + Cypherock may take an additional 1-2% commission.

On-chain transaction fees — paid to miners / validators, not Cypherock

Each on-chain transaction (Bitcoin, Ethereum, EVM, Solana, etc.) requires a network fee paid to miners / validators. The Cypherock X1 doesn't charge any wallet-side fee on top — it only signs the transaction. The user sets the fee in the Cypherock App's send flow (basic low / medium / high fee presets; no custom sat/vB control like Coldcard / Foundation Passport's granular fee control via Sparrow).

No subscription + no cloud account

The Cypherock X1 has no subscription, no cloud account, no in-app purchases — the user pays only the hardware cost + on-chain transaction fees (paid to miners) + 3% processor fee (when using buy/sell) + 0.5-1.5% swap spread (when using swap). This is comparable to Foundation Passport + Keystone 3 Pro. Ledger's paid Ledger Recover subscription + Trezor Suite premium are not present in the Cypherock model.

The Cypherock X1 supports the multi-chain ecosystem. The broader chain coverage is comparable to Ledger Nano X + Trezor Safe 5 + Keystone 3 Pro (multi-chain air-gapped wallets); broader than Coldcard + Foundation Passport (Bitcoin-only). The exact supported-chains list is maintained in the Cypherock App's chain-config; the following are the major supported chains:

Bitcoin ecosystem

• Bitcoin (BTC) — on-chain + SegWit / Bech32 + Taproot
• Bitcoin Cash (BCH)
• Litecoin (LTC)
• Dogecoin (DOGE)

Ethereum + EVM + L2s

• Ethereum (ETH) + all ERC-20 tokens
• USD Coin (USDC) + Tether (USDT) on multiple networks
• BNB (BSC) + BEP-20
• Polygon (MATIC / POL) + Avalanche (AVAX)
• Optimism + Arbitrum

Major altcoins + L1s

• Solana (SOL) + Solana SPL tokens
• Cardano (ADA)
• Polkadot (DOT)
• XRP (Ripple)
• Tron (TRX)
• Tezos (XTZ)
• Aptos (APT) + Sui (SUI)
• + many more major L1s and L2s

Stablecoins

The Cypherock X1 supports major stablecoins (USDT, USDC, DAI, BUSD, etc.) across their respective issuances / networks — comparable to Ledger Nano X + Trezor Safe 5 + Keystone 3 Pro stablecoin coverage.

Hardware-wallet pairing — paired with the Cypherock App (mobile, closed-source with open-source SDK)

The Cypherock X1 vault is paired with the Cypherock App (mobile, iOS + Android, closed-source firmware / open-source SDK at github.com/cypherock). The Cypherock App provides watching + sending + receiving + dApps (WalletConnect) + buy/sell + swap (when available) + stake (when available). This is the first-party companion-app model, comparable to Ledger Nano X (Ledger Live) + Trezor Safe 5 (Trezor Suite) + Foundation Passport (Envoy) + Keystone 3 Pro (Keystone App). For users who want no-app-lock-in hardware-wallet pairing with the broadest set of open-source watching-only wallets (Sparrow + Electrum + BlueWallet + Specter + Nunchuk + Cove), the recommended alternative is Coldcard.
