Yes. The Cryptnox Crypto Hardware Wallet – Dual-Card Set can hold ETH on Linea after you manually add the Linea EVM network in the Cryptnox app. Linea is not pre-programmed on the card. ETH is held as the native gas coin on the Linea EVM layer 2 network, using a 0x-prefixed 20-byte EVM address. Private keys are generated inside the secure element and never leave it.
CRYPTNOX products are also available worldwide through our official Amazon stores.
ETH on Linea is not a pre-enabled asset on the Cryptnox card. A buyer who wants to use Linea adds the EVM network once in the free Cryptnox app on iOS or Android. The setup route is manual: use Add a Network for Linea, or use Add a Token when the goal is to show or use a token on Linea. ETH itself is the native gas coin for Linea activity.
That distinction matters before purchase. You are not buying a card that arrives with a Linea coin slot already configured. You are buying the Cryptnox Crypto Hardware Wallet – Dual-Card Set and then enabling Linea through the app’s EVM network path. After Linea is added, the account uses the EVM address format: a 0x-prefixed 20-byte address.
Because Linea is reached by manual EVM setup rather than by a pre-programmed card profile, the Cryptnox coin and blockchain support page is useful when comparing Linea with other networks before configuring the app.
Linea is an Ethereum layer 2 network, and ETH on Linea is used in the Linea network context. Linea’s own materials describe its Ethereum relationship, including in Linea’s explanation of how it relates to Ethereum. For a buyer, the practical point is direct: ETH on Linea is not the same network position as ETH on Ethereum mainnet, even though the address format is EVM-style.
When you add Linea in the Cryptnox app, you are adding the network on which that ETH is used as gas. A 0x address is familiar to Ethereum users, but the 0x prefix does not tell you which chain a transfer or Web3 session is using. Linea must be selected when your intention is to receive, send, or use ETH on Linea.
The official Linea documentation is the right external reference for Linea’s network environment. Cryptnox adds the hardware-wallet layer for the private key used with the Linea EVM address after the network has been manually added.
Linea uses a 0x-prefixed 20-byte EVM address. That address style is shared by many EVM networks, so it is convenient but also easy to misread. On this page, the address is the account format for ETH on Linea after Linea has been added through the Cryptnox app. The address format alone does not turn a Linea transaction into an Ethereum mainnet transaction, a Polygon transaction, or a Ronin transaction.
For buyers who already use EVM chains, Linea should be treated as its own network choice. The visible address style may look familiar, but the asset here is ETH as Linea’s native gas coin. Before receiving ETH, confirm that the sending side is using Linea. Before using ETH in Web3, confirm that the connected session is set to Linea.
Cryptnox private keys are generated inside the secure element and never leave it. For Linea, that means the key for the EVM account is created inside the card’s secure element, while Linea is added as the EVM network in the app. The secure element uses an EAL6+-certified chip.
If you are comparing Linea with another EVM network, the Polygon hardware wallet page is a useful contrast: Polygon and Linea both use 0x-style EVM addresses, but a buyer must still choose the intended network deliberately.
The Dual-Card Set ships uninitialised, which is important for a Linea buyer because the Linea account is not a preloaded account on the product. During setup, the seed is generated inside both secure elements. The second card is therefore the backup for the same wallet seed from the start, before you manually add Linea in the Cryptnox app.
This backup model fits Linea’s manual EVM setup route. You initialise the two-card set first, then add Linea as a network. If the Linea network has been added in the app, the same wallet seed protected by the two cards is the basis for the EVM account used on Linea. There is no recovery phrase to write down by default. Importing an existing BIP39 recovery phrase is available as an advanced option rather than the normal first setup path.
The Cryptnox hardware wallet tutorials are the right place to review product setup before adding Linea. Linea setup comes after card initialisation because Linea is a manually added EVM network, not a pre-programmed card asset.
The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For ETH on Linea, that gives the buyer a clear workflow: add Linea in the app, use a 0x-prefixed EVM account, and make sure the connected Web3 session is using Linea when ETH on Linea is needed for gas.
The important Linea-specific risk is not the address format; it is the selected network. A Web3 session may show an EVM-style address, but ETH on Linea is used on Linea. If a session is pointed at another EVM network, the familiar 0x address format can make the mistake less obvious. Treat the network name as part of the transaction context.
If your EVM use extends beyond Linea, compare the network assumptions on the Ronin hardware wallet page. Ronin and Linea are separate networks, so the buyer’s habit should be to verify the chain, not only the address shape.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set is a contact and NFC smart card. In Linea use, that means you can tap the card to a phone while adding the Linea EVM network in the mobile app, or insert the card into a reader when using the contact interface. The form factor is dual-interface; Linea is still added manually in the app.
The card itself has no fingerprint or face sensor. Unlock uses the phone’s face or fingerprint unlock through the Cryptnox app when supported and enabled on the phone. For Linea, the separation is straightforward: the phone runs the app where Linea is added and Web3 connections are managed, while the card’s secure element protects the private key for the EVM account.
The product is Swiss-engineered, and the cards are made in Switzerland. The exact product for this Linea setup is the Cryptnox Crypto Hardware Wallet – Dual-Card Set. Buy it with the expectation that Linea is manually added after setup, not already installed as a ready-made Linea profile.
Linea activity can be managed through the mobile app and Web3 connection route. A tap-to-phone smart card keeps Linea network setup and Linea session handling in the app, while key generation and key protection remain inside the secure element on the card.
ETH on Linea is a good fit for the Cryptnox Dual-Card Set when you want a hardware wallet for an EVM layer 2 account and you are comfortable adding the network manually. The product should not be chosen on the assumption that Linea ships enabled. It should be chosen because it can protect the private key for the Linea EVM address after Linea has been added in the app.
The buying decision is different from a non-EVM asset decision. Linea uses a 0x-prefixed 20-byte address, ETH is the native gas coin on the Linea network, and Web3 access is through WalletConnect and MetaMask from the Cryptnox app. A buyer who uses multiple networks should check the network path for each asset before moving funds.
For comparison, the TRON hardware wallet page covers a different chain model, while the Bitcoin hardware wallet page covers an asset that does not use the Linea EVM address format. Those differences make Linea’s manual EVM setup route the central detail on this page.
If you want to compare the smart card product range before buying for ETH on Linea, the Cryptnox hardware wallet collection hub places the Dual-Card Set among the available Cryptnox hardware wallet options.
No. Linea is not pre-programmed on the card. ETH on Linea is supported by manually adding the Linea EVM network in the Cryptnox app. The buyer adds the network once through Add a Network, or adds a Linea token through Add a Token when token display or use is needed.
For Linea, the Cryptnox wallet can hold ETH as the native gas coin on the Linea EVM layer 2 network. This is not a separate preloaded card asset. The account uses a 0x-prefixed 20-byte EVM address after the Linea network has been manually added in the app.
ETH on Linea uses a 0x-prefixed 20-byte EVM address. That format is familiar from Ethereum-style networks, but the network still matters. A 0x address does not prove that a transfer or Web3 session is on Linea, so Linea must be selected when using ETH there.
Private keys are generated inside the secure element and never leave it. For ETH on Linea, the key for the EVM account is protected by the card’s secure element, while Linea is added as the manually configured EVM network in the Cryptnox app.
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.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup. Linea is then added manually in the app. There is no recovery phrase to write down by default; importing a BIP39 recovery phrase is an advanced option.
Yes. The free Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For Linea, make sure the Linea network has been added and that the connected session is using Linea, because ETH on Linea is the gas coin for that network.
No. The card itself has no fingerprint or face sensor. Unlock uses the phone’s face or fingerprint unlock through the Cryptnox app when the phone supports it and the feature is enabled. The card’s secure element remains the place where the private key is protected.
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.
