Cypherock

Cypherock is a hardware wallet maker. Its Cypherock X1 is a cold wallet with no seed phrase to write down. The X1 splits your private key into pieces. One piece sits in a small device with a screen, called the X1 Vault. The others sit on NFC smart cards. Any two pieces can rebuild the key, so a single lost or stolen piece gives nobody your funds. The X1 holds SOL and thousands of other assets, per Cypherock's website, and you manage it in the cySync app. It is built for long-term holders who fear losing a backup more than they value speed.

How the Cypherock X1 works: a 2-of-5 Shamir key split

The Cypherock X1 uses Shamir Secret Sharing, a method that cuts a secret into parts so that a set number of them can rebuild it. The X1 makes five parts and needs any two. You sign a transaction with the X1 Vault plus any one X1 Card. If the Vault breaks, two cards can recover the wallet.

So you can lose three of the five parts and still reach your funds. A thief who finds one card, or the Vault alone, gets nothing usable.

The X1 still works on a standard recovery phrase underneath. Cypherock's documentation says the wallet is BIP39 compliant, the common standard behind 12- and 24-word seed phrases. With the Vault and one card, you can display the 24-word phrase and move it to any other BIP39 wallet. So your funds are not locked to Cypherock's hardware if the company ever closes.

You can also run the process the other way. Cypherock lets you import an existing seed phrase from another wallet and store it split across the cards, so the X1 can act as a backup vault for keys you already use elsewhere.

The X1 Vault, X1 Cards and PIN

The X1 Vault is a small device with a 0.96-inch OLED screen and a joystick. It connects to a computer by USB cable and has no Bluetooth. You check each transaction on its screen before approving it.

The four X1 Cards are passive NFC cards built on EAL6+ certified secure elements, the class of tamper-resistant chip used in bank cards. The Vault and a card talk over encrypted NFC when you tap them together. Per the technical documentation, the cards are deliberately not upgradeable, so a bad firmware update cannot reach the key pieces stored on them.

A 4 to 8 character alphanumeric PIN protects each wallet. Repeated wrong guesses trigger a lock that grows longer each time. The Vault mixes randomness from two separate chips when it creates a key, so one faulty chip cannot produce a guessable key.

Using Solana (SOL) with the Cypherock X1 and cySync

You can store, send and receive SOL on the Cypherock X1. Cypherock lists Solana among the networks its cySync app supports, next to Bitcoin, Ethereum, XRP, Tron and others. cySync shows your balance and transaction history, and your SOL sits alongside your other chains in one portfolio view.

cySync runs on Windows, macOS and Linux. A mobile cySync app is listed on the Apple App Store, though it was still on early 0.1 versions in 2026. The app also offers in-app swaps and a fiat on-ramp through Binance Connect.

For Solana apps, cySync connects through WalletConnect. Coin Bureau's June 2026 hands-on review notes that Solana dapp and NFT access depends on the app version and region, so test a small transfer before you rely on a specific Solana app.

One device can hold up to four independent wallets, each with its own key and addresses. You could keep a long-term SOL wallet separate from an everyday DeFi wallet without buying a second device.

If you already hold SOL in Solflare or Phantom, you can import that seed phrase into the X1 and keep the backup split across the cards instead of on paper.

Cypherock Cover: crypto inheritance and estate recovery

Cypherock Cover is the company's inheritance feature. Its main tool, Estate Recovery, passes access to a person you choose if you stop responding to check-ins.

You pick up to four wallets and add a nominee in cySync. You keep one X1 Card and give one to your nominee. You also set a reminder period and write a final message. If you go quiet past that period, Cypherock follows up for a month. If you still don't respond, an encrypted message goes to your nominee with instructions.

To reach the seed phrase, the nominee still needs two cards, or one card plus the Vault, and the PIN you set. Cypherock never holds a key piece. Its server stores only an encrypted message. You can name up to two nominees; the second gets the email three months after the first. The service is described as non-KYC.

The trade-off is that the check-in and the message delivery depend on Cypherock's servers running. Pair Cover with a written plan for your heirs.

Cypherock X1 price, Standard and Pro packages, and the X0

The base X1 package sold for $99 when Coin Bureau reviewed it in June 2026, down from a list price of $129. Each package has the X1 Vault, four X1 Cards, a cable and a case. Cypherock also sells Standard and Pro versions. Check what each one includes on the store before you buy.

In August 2026, Cypherock announced the Cypherock X0. It called the X0 the "most affordable hardware wallet in the world". It gave no price, specs or launch date. We found no launch by mid-October 2026.

Who the Cypherock X1 suits

The Cypherock X1 suits long-term holders with enough at stake that a lost seed phrase would hurt, and who are willing to manage five physical items. It fits people planning crypto inheritance, and people who want to keep backup pieces in different places, such as home, an office and a relative's house.

It is a weaker fit if you want something small and simple. The X1 has more parts to store, a small screen, and no Bluetooth or touchscreen. Active Solana traders who sign many transactions a day may find tapping a card for each one slow. If you hold a small amount of SOL, a cheaper single-device wallet is easier to justify.

Is Cypherock safe? Audits, open source and known risks

Cypherock's design removes the single paper backup behind many self-custody losses, and most of its code is public. But the X1 has taken real criticism, and its main audit dates from 2022.

Keylabs audited the X1 hardware and firmware in 2022. Keylabs is the security firm behind the wallet.fail attacks on Ledger and Trezor devices. Cypherock says it fixed every finding and posted the report with its reply. The audit covers the X1 as it was then. It does not cover later firmware, the mobile app or Cypherock Cover.

The X1 Vault firmware and the cySync app are open source on GitHub. The code on the X1 Cards is closed, because the chip maker requires a non-disclosure deal. WalletScrutiny lists the firmware as reproducible. That means anyone can rebuild it from the code and check it matches. But WalletScrutiny's page says its main author on this review also works on Cypherock, so the verdict is not fully independent.

Other risks to weigh:

• The 2-of-5 threshold cuts both ways. The Vault plus one card can sign, so if you keep a card next to the Vault, a thief or a coercer needs only those two items plus your PIN. Decrypt's 2025 review raised this point.
• Early Vaults used the ATECC608A secure element, which Ledger's Donjon team says it broke with laser fault injection. Cypherock told Decrypt that current production batches use the newer ATECC608C.
• Device authentication checks the Vault and cards against Cypherock's servers before first use. That guards against tampered devices but adds a dependency on the company.
• Cypherock is a small company with a single disclosed $1 million funding round. The BIP39 export path is your exit if the company stops trading, so learn it while things are working.

Cypherock vs Ledger, Trezor and Tangem

Choose the Cypherock X1 if backup risk worries you most. Choose a mainstream wallet if you value app maturity and wide dapp support.

Against Ledger, the X1 removes the single seed phrase and has open-source Vault firmware. Ledger has the more mature app, Bluetooth on some models and broader third-party support. Against Trezor, the trade is similar: Trezor is cheaper, simpler and fully open source, but relies on a standard seed phrase backup.

Tangem also uses NFC cards with no seed phrase, at a lower price. Tangem has no screen of its own, though, so you verify transactions on your phone. The X1 Vault gives you an independent screen.

Solana users have other options. Keystone offers an air-gapped device that signs by QR code. Solflare launched the Solar Shield, a $49 NFC tap-to-sign card, at Breakpoint 2025. For a wider view, see our roundup of wallets for Solana staking, NFTs and DeFi.
