Yes. Arbitrum One is pre-programmed in the Cryptnox app, so you do not need to add the network before using it. With the Cryptnox Crypto Hardware Wallet – Dual-Card Set, Arbitrum One keys are generated inside the card secure element and never leave it. You use the free Cryptnox app on iOS or Android, add ERC-20 tokens when needed, connect to Web3 through WalletConnect, and work with MetaMask.
CRYPTNOX products are also available worldwide through our official Amazon stores.
Buying a hardware wallet for Arbitrum One should not start with a manual network build. Arbitrum One is pre-programmed in the Cryptnox app, so the network is already available when you set up the wallet. That is the key difference between this Arbitrum One page and a general EVM setup: you do not need to enter Arbitrum One through Add a Network before using it.
The product for this page is the Cryptnox Crypto Hardware Wallet – Dual-Card Set. The set gives Arbitrum One users two smart cards from the same setup, with the second card serving as the backup after initialisation. Private keys for the wallet are generated inside the secure elements and never leave them.
The support route is direct: install the free Cryptnox app on iOS or Android, initialise the Dual-Card Set, choose Arbitrum One from the app’s network list, and add the ERC-20 tokens you want to manage on that network. The app also connects to Web3 through WalletConnect and works with MetaMask, so Arbitrum One can be used through established Web3 connection flows while the card remains the signing device.
If you are checking Arbitrum One alongside other assets before buying, the Cryptnox coin and blockchain support page gives the broader network view.
Arbitrum One support in Cryptnox is not limited to the network name appearing in a menu. The app route lets you manage the native coin for the Arbitrum One network and ERC-20 tokens deployed on that chain. When an ERC-20 token is not already visible in your app view, you can add it manually through Add a Token.
This matters because many Arbitrum One buyers are not looking for a single-asset wallet. They want the Arbitrum One network available first, then the ability to add the tokens they actually use on that chain. Cryptnox handles that split clearly: the Arbitrum One network is already present, while ERC-20 tokens can be added as needed.
Arbitrum One is the pre-programmed EVM route. Other EVM networks use the Add a Network function. After an EVM network is added, its native coin and ERC-20 tokens deployed on that chain can be managed. This gives Arbitrum One users a practical distinction: your Arbitrum One setup begins from an existing app entry, while additional EVM networks can be added later through the app.
For buyers comparing Arbitrum One with other EVM pages, the Cryptnox hardware wallet for Polygon page is a useful adjacent comparison because it also helps frame EVM network handling.
The Dual-Card Set ships uninitialised. During setup, the wallet seed is generated inside both secure elements, so the second card becomes the backup for the same wallet. For an Arbitrum One buyer, that means the backup is created as part of the same card-based setup used before selecting and managing Arbitrum One in the app.
The default setup does not require writing down recovery words. That is an important part of the Cryptnox buying decision for Arbitrum One: the backup is the second card, not a phrase that must be copied during the normal setup path. Importing an existing BIP39 recovery phrase is available as an advanced option, but it is not the default route for a new Dual-Card Set.
For Arbitrum One, the clean path is to initialise the two cards first, confirm that the backup card belongs to the same wallet set, and then use the Arbitrum One network already present in the Cryptnox app. The Cryptnox startup guide is the right starting point before relying on either card for Arbitrum One transactions.
After setup, one card can be used for regular Arbitrum One access while the second card is kept separately as the backup for that same wallet.
Arbitrum One activity often passes through mobile apps, WalletConnect sessions, and MetaMask workflows. Cryptnox separates those interfaces from the place where the private key is created and kept. For the Arbitrum One wallet, private keys are generated inside the secure element and never leave it.
Each card uses an EAL6+-certified chip. That property belongs to the chip and platform. In practice, the Arbitrum One key material is created inside the secure element rather than being handled as ordinary app data during setup. The Cryptnox app helps you use Arbitrum One, add ERC-20 tokens, and connect to Web3, while the card remains the signing environment.
The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. That gives Arbitrum One users two common access paths without changing where the private key lives. The app can be the route into a Web3 connection, and MetaMask can be part of the workflow, while the card protects the key used for signing.
Unlock is handled through the phone’s own face or fingerprint check in the Cryptnox app. The card itself has no face or fingerprint sensor. For Arbitrum One, that means the phone performs the user unlock step in the app, and the card keeps the private key inside its secure element throughout the signing flow.
Bridging into or out of Arbitrum One usually goes through a bridge aggregator; the DeFi and bridge aggregator guide explains how those routes work and how the card signs each leg.
The Cryptnox card is a contact and NFC smart card. For Arbitrum One, that gives you two ways to use the same wallet form factor: tap the card to a phone for the mobile app route, or insert the card into a smart-card reader for a contact workflow. It is a dual-interface card, not a phone-only card.
This card format fits the way many Arbitrum One users move between mobile Web3 connections and desktop-style MetaMask flows. The app provides the Arbitrum One network entry and the Web3 connection route. The physical card remains separate from the phone or computer that is used to interact with the app or connected tools.
The NFC path is useful when using the Cryptnox app on a phone. The contact path is useful when a reader workflow is preferred. Both paths use the same card-based wallet model for Arbitrum One, with private keys generated inside the secure element and kept there.
If you are still comparing form factors before choosing an Arbitrum One wallet, the broader Cryptnox hardware wallet guide places the card-based model beside the rest of the product family.
Arbitrum One may be the reason for buying the wallet, but the Cryptnox app also supports a wider EVM route. Any EVM network can be added through Add a Network. After that, the native coin for the added network and ERC-20 tokens deployed on that chain can be managed. Arbitrum One remains simpler because it is already pre-programmed.
This distinction helps when comparing chain pages. A buyer focused on Arbitrum One should not have to infer support from general EVM language alone: Arbitrum One is already in the app. A buyer who also uses other EVM networks can add those networks separately. ERC-20 handling stays consistent because tokens can be added manually through Add a Token when needed.
If your shortlist includes more than one network, compare the Arbitrum One route with the Cryptnox hardware wallet for Tron page and the Cryptnox hardware wallet for Ronin page. Those sibling pages help you evaluate how each network is presented in the Cryptnox wallet collection.
Bitcoin buyers have a different network context from Arbitrum One users, so the Cryptnox hardware wallet for Bitcoin page is also useful when you want to compare an EVM asset page with a non-EVM asset page.
A buyer looking for the best Arbitrum wallet is usually deciding on three practical points: whether Arbitrum One is directly supported, how the signing keys are protected, and how backup works. Cryptnox addresses those points with a pre-programmed Arbitrum One network, secure-element key generation, and a second card that serves as the backup after the Dual-Card Set is initialised.
The Arbitrum One experience is not built around manually entering the network first. It starts from an existing app entry, then lets you add ERC-20 tokens deployed on Arbitrum One when you need them. That makes Cryptnox a clear fit for users who want Arbitrum One support in the app and hardware-card signing for the keys behind that wallet.
If Arbitrum One is part of a wider hardware-wallet comparison, start with the Cryptnox hardware wallet collection and then review the network-specific pages that match your holdings. When you are ready to buy the Arbitrum One-capable card set, use the official Cryptnox shop page for the Crypto Hardware Wallet – Dual-Card Set.
Yes. Arbitrum One is pre-programmed in the Cryptnox app, so you do not need to add the network manually before using it. After the Dual-Card Set is initialised, you can select Arbitrum One in the app and add ERC-20 tokens deployed on that network when needed.
No. Add a Network is not required for Arbitrum One because Arbitrum One is already pre-programmed in the Cryptnox app. Add a Network is used for other EVM networks. Once another EVM network is added, its native coin and ERC-20 tokens deployed on that chain can be managed.
Yes. ERC-20 tokens deployed on Arbitrum One can be added manually through Add a Token. This is useful when the Arbitrum One network is already available in the app but a specific token you hold is not yet shown in your app view.
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 Arbitrum One users, that means the backup is card-based by default rather than a recovery phrase written down during normal setup.
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.
Private keys are generated inside the card secure element and never leave it. The Cryptnox app provides the Arbitrum One network route, ERC-20 token addition, WalletConnect access, and MetaMask workflow support, while the card remains the protected signing environment for the wallet.
No. The card itself has no fingerprint or face sensor. Unlock uses the phone’s own face or fingerprint check through the Cryptnox app. For Arbitrum One activity, the phone handles that unlock step while the private key stays inside the card secure element.
Yes. The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. This lets Arbitrum One users keep familiar Web3 workflows while the Cryptnox card protects the private key used for signing.
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.
