Cryptnox supports Wormhole W as the ERC-20 W token on EVM networks such as Ethereum, Base, Arbitrum and Optimism after you add the network or token in the Cryptnox app. W is not pre-programmed on the card, and this route is not for the Solana SPL W token. Your W is managed through a 0x-prefixed 20-byte EVM address, with private keys generated inside the secure element and never leaving it.
CRYPTNOX products are also available worldwide through our official Amazon stores.
Wormhole W has two relevant token routes for a buyer to separate before making a transfer: SPL W on Solana and ERC-20 W on EVM networks. The Cryptnox Crypto Hardware Wallet – Dual-Card Set holds W through the ERC-20 route on EVM networks such as Ethereum, Base, Arbitrum and Optimism. It is not the route for holding the Solana SPL W token directly.
W is not pre-programmed on the card. After the card setup is complete, you add the EVM network or add the W token once in the free Cryptnox app on iOS or Android. The W balance then belongs to the 0x-prefixed 20-byte EVM address controlled by the private key in the card’s secure element.
Wormhole describes W as natively multichain through Native Token Transfers on Ethereum and layer 2 networks, so the chain and token standard matter as much as the token name. Before buying for W, compare the W route with the wider Cryptnox coin and blockchain support page so the network you intend to use matches the way W is added in the app.
The product page for the Cryptnox Crypto Hardware Wallet – Dual-Card Set is the purchase route for the two-card smart-card setup described here.
The W token entry is added by the user; it does not arrive already enabled on the card. For W on Ethereum, Base, Arbitrum or Optimism, the practical choice is whether the EVM network is already visible in the Cryptnox app. If it is not visible, use Add a Network. If the network is visible but W is not displayed, use Add a Token.
This setup distinction is important for W because the same asset name can appear beside different chain labels. A Solana SPL W transfer and an ERC-20 W transfer are not the same route. The Cryptnox route on this page is the ERC-20 version on an EVM network, shown against a 0x-prefixed address.
For the order of operations, complete the card and app setup first, then add W through the EVM route you plan to use. The Cryptnox hardware wallet tutorials are the relevant place to review setup and wallet actions before adding a W token entry.
For ERC-20 W, the token balance is controlled by the private key behind the 0x-prefixed EVM address. In the Cryptnox Dual-Card Set, private keys are generated inside the secure element and never leave it. Adding W to the app makes the ERC-20 token visible for the chosen EVM route; it does not export the key from the card.
The card uses an EAL6+-certified chip. For a W holder, that chip protects the key used to sign actions for the EVM address where ERC-20 W is held. The certification is a property of the chip platform, while the product is a contact and NFC smart card used with the Cryptnox app.
That form factor matters for W because the card can be tapped to a phone when adding or using W in the app, or inserted into a reader when your setup calls for contact use. The card is dual-interface, so the W workflow is not limited to a single contact method.
When you approve an ERC-20 W transfer or a W-related Web3 action, the app prepares the action and the card protects the key material used to sign it. The items to verify are the W route, the EVM network, and the recipient or approval details. The card’s role is to keep the private key inside the secure element while the W action is signed.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup for the same wallet. For W, this protects the key behind the EVM address that holds the ERC-20 token route you added in the app.
No recovery phrase has to be written down by default. If W is added again later in the app view, that token entry is only the display route; the essential item is the private key behind the 0x-prefixed EVM address. The second card backs up that wallet because it is initialised with the same seed inside its secure element.
Importing an existing 12/24-word BIP39 seed phrase is available as an advanced option, but the default path for a new W setup is to generate the seed inside both secure elements during Dual-Card Set initialisation. That default is especially direct for an ERC-20 token such as W: add the EVM network or token after setup, then use the backed-up card pair to manage the address.
If you are choosing between hardware wallet form factors for a W address, the Cryptnox hardware wallet collection gives the broader product context for the smart-card approach used by the Dual-Card Set.
The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. For W, that matters when the service you are using expects an EVM wallet address and the W token is held as ERC-20 on Ethereum, Base, Arbitrum or Optimism.
Before approving a W-related Web3 action, check that the connected network is the EVM network where the ERC-20 W token was added. The card does not turn a Solana SPL W route into an ERC-20 route, and it does not change the network selected by a Web3 service. It signs for the EVM address controlled by the private key inside the secure element.
Wormhole has announced governance staking for W token holders. If a W governance or staking action is presented through an EVM workflow, treat the chain label and token standard as part of the approval review before signing with the card.
The Dual-Card Set fits a W buyer who wants to manage ERC-20 W on EVM networks such as Ethereum, Base, Arbitrum and Optimism through a 0x-prefixed address. It is not the right route for direct Solana SPL W holding, because this setup is based on adding W as an ERC-20 token or adding the relevant EVM network in the Cryptnox app.
Choose this route when the private key for your W address should be generated inside a secure element and remain there. The second card is part of the default backup model because the seed is generated inside both secure elements during initialisation. The cards are Swiss-engineered and use a contact and NFC smart-card workflow: tap to a phone, or insert into a reader.
Unlock uses the phone’s fingerprint or face unlock through the Cryptnox app. The card itself has no fingerprint or face sensor. For W transfers and approvals, the card’s role is to keep the private key inside the secure element and sign for the 0x-prefixed EVM address.
If you are planning chain support beyond W, keep each chain decision separate from the W token route. The W page here is about ERC-20 W on EVM networks; the Polygon hardware wallet page is the better internal comparison for a separate EVM-chain question, while the Bitcoin hardware wallet page covers a different asset route entirely.
The most common W mistake is treating the token name alone as enough information. W exists as an SPL token on Solana and as an ERC-20 token on Ethereum, Base, Arbitrum and Optimism. The Cryptnox route described here is only the ERC-20 W route on EVM networks.
A 0x-prefixed 20-byte EVM address is the address format for the W route on this page. A Solana SPL W route is different and is not the direct holding route described for this Cryptnox card setup. If the service sending W asks for a chain choice, the choice must match the ERC-20 W route you added in the app.
The card secures the private key for the EVM address. It does not convert W between Solana and EVM networks, and adding a token entry in the app does not change the standard of a token sent from another service. For separate chain pages that should not be confused with W, use the TRON hardware wallet page or the Ronin hardware wallet page when those networks are the actual buying question.
Yes. You can hold Wormhole W as an ERC-20 token on EVM networks such as Ethereum, Base, Arbitrum and Optimism. Add the relevant EVM network or add the W token in the Cryptnox app. This route is not for holding the Solana SPL W token directly.
No. W is not pre-programmed on the Cryptnox card. After the Dual-Card Set is initialised, add the EVM network or add the W token in the Cryptnox app. W is then managed through the 0x-prefixed EVM address controlled by the card.
Use a 0x-prefixed 20-byte EVM address for the ERC-20 W route. That applies to W on EVM networks such as Ethereum, Base, Arbitrum and Optimism. Do not use the Solana SPL W route for the setup described on this page.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup for the same wallet. For W, that means the backup protects the key behind the EVM address used for ERC-20 W.
No. Unlock uses the phone’s fingerprint or face unlock through the Cryptnox app. The card itself has no fingerprint or face sensor. For W transfers and approvals, the card’s role is to keep the private key inside the secure element and sign the EVM action.
Yes. The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. For W, confirm that the Web3 service is using ERC-20 W on the EVM network where your token is held before approving the action.
No. W exists as an SPL token on Solana and as an ERC-20 token on Ethereum, Base, Arbitrum and Optimism. The Cryptnox route on this page is the ERC-20 W route on EVM networks, using a 0x-prefixed EVM address.
No, and on this network that is not a limitation. The Cryptnox wallet uses one address per chain. HD address rotation comes from Bitcoin’s UTXO model and the BIP32/BIP44/BIP49/BIP84 derivation scheme; on account-model networks each account is a single fixed address by design, so the question does not apply in the same way. Cryptnox’s single-address-per-chain behaviour matches how these networks work.
At the cryptography layer the card derives keys along BIP32 and SLIP-10 paths, one path per supported chain, though that is not exposed in the app as multi-address management.
Yes. Cryptnox ships worldwide from the official CRYPTNOX store. Orders to Switzerland, the European Union and the United States are dispatched from stock already held in each of those regions, so the parcel does not cross a customs border into your country and there are no import duties to pay. Orders to other destinations are shipped internationally, and any import duties or local taxes are set by the destination country and are the recipient’s responsibility. Current shipping rates are shown at checkout.
