Holders pick a pair in cySync and confirm on the device. Funds move from wallet to wallet, while the private key remains split between the X1 Vault and cards.
Most people buy a Cypherock X1 to solve one thing: keep crypto safe without trusting an exchange. The device splits your private key into five shards across a Vault and four cards, so no single point ever holds enough to be compromised.
What it never solved was the moment you actually want to move.
That moment shows up often. An asset runs up, and you want to take some profit into stables. A token you have been watching lists finally, and you want in before the crowd. Both are swaps, and until now, a swap forced an uncomfortable choice.
The first option is to move funds onto a centralized exchange to trade, then bring them back to cold storage. It works mechanically, yet it quietly undoes the reason you bought the device in the first place. Your assets sit on a platform you do not control, exposed to the kind of freeze or collapse that wiped out FTX and Celsius.
The second option is to route the swap yourself through hot wallets and decentralized venues. This keeps you in self-custody, but it is slow and easy to get wrong. You choose the bridges and intermediary tokens by hand, and your keys touch a connected environment on every transaction.
The job behind the swap
Strip away the tooling, and the job is plain. When a holder needs to swap crypto they keep in cold storage, they want to act on the market without giving up custody or parking funds on an exchange. Safety and access should not pull against each other.
That is the job this integration was built around.
What changed
SimpleSwap's swap engine now runs directly on the Cypherock X1, so the exchange occurs on the device itself rather than elsewhere.
You pick the pair in the cySync app and confirm it by tapping one of your X1 Cards on the Vault. Funds travel wallet-to-wallet, while SimpleSwap scans 20+ liquidity providers across CEX and DEX sources to build the route for you. There is no exchange account to open and no balance to leave behind on a platform you do not own. Your private key stays distributed across the Vault and the cards from start to finish.
For a Cypherock holder, that flips the X1 from a place to park assets into a place to use them. The device people trust to guard their holdings now reaches 2,800+ swappable assets through aggregated liquidity, without that liquidity ever entering custody.
Why the engine matters for this user
Cypherock owners tend to hold real size, so execution quality is not a small detail. SimpleSwap has operated since 2018, processing more than 20M swaps for over 10M users. It routes through 20+ providers, which can soften the price impact on large orders, even those worth hundreds of thousands of dollars. For the majority of floating swaps, the estimated accuracy reaches 99.998%, so the amount you are quoted is the amount that lands.
Set that record next to Cypherock's own security work, audited by Keylabs (the firm that found flaws in Ledger and Trezor) and built on EAL 6+ secure elements. The result is liquidity access that fits a cold-storage threat model instead of fighting it.
"Cold wallets solved storage years ago. What they never solved was what happens when you want to move. We built our engine into the X1 so a holder can swap without breaking self-custody. The keys stay on the device, and the funds go wallet-to-wallet. The routing is our problem, not the user's."
— Stefan Lauer, Head of Infrastructure SimpleSwap
"The X1 already proved private keys don't need to touch the internet to be useful. This integration proves the same about liquidity. SimpleSwap's routing happens off the device, the signing happens on it, and the two never have to trust each other. "
— Akhil Jonnavithula, Director of BD Cypherock
