Yes. Base Mainnet is pre-programmed in the Cryptnox app, so you do not need to add the network manually before using it. With the Cryptnox Crypto Hardware Wallet – Dual-Card Set, private keys are generated inside the secure element and never leave it. You manage Base through the free iOS or Android app, use the second card as the backup, and connect to Web3 through WalletConnect and MetaMask.
CRYPTNOX products are also available worldwide through our official Amazon stores.
Base Mainnet is already pre-programmed in the Cryptnox app. A Base buyer does not need to begin by entering custom network details through Add a Network. The Base route starts with selecting Base Mainnet in the app, then managing the native coin of that EVM network and ERC-20 tokens deployed on Base.
The product for this Base setup is the Cryptnox Crypto Hardware Wallet – Dual-Card Set. It is a contact and NFC smart card set for buyers who want Base access in a card form factor. You can tap a card to a phone, or insert it into a reader.
This matters if Base is the chain you want to use first. Base Mainnet is not treated like an unlisted EVM network in the app; it is already present. If you want to check Base alongside other coin and network routes before buying, the Cryptnox coin and blockchain support page gives the broader support view.
For Base Mainnet, the starting point is the network selection inside the Cryptnox app. Base is already listed there. After Base Mainnet is selected, the app can manage the native coin of that EVM network and ERC-20 tokens deployed on Base.
ERC-20 tokens on Base follow the token route in the app. If a Base-deployed ERC-20 token needs to be shown manually, use Add a Token. This keeps the Base token step separate from the network step: Base Mainnet is already present, while individual tokens can be added when needed.
That separation is useful for buyers who hold more than one Base asset. You do not repeat network setup for each Base ERC-20 token. Base Mainnet stays as the chain route, and Add a Token is used only for the token entries that need to be added manually.
For first-time card setup before using Base, the Cryptnox startup guide explains how to get the Dual-Card Set ready for use.
When you use Base Mainnet with Cryptnox, private keys are generated inside the secure element and never leave it. The card uses an EAL6+-certified chip, and that certification applies to the chip platform.
The Cryptnox app is the interface for Base activity on the phone, but the phone is not where the private keys are generated. For a Base buyer, the important point is that the app provides the Base network route while the private keys remain inside the secure element.
This is the security model behind Base use with the Dual-Card Set. Base Mainnet appears in the app, Base ERC-20 tokens can be added when needed, and the private-key operation stays tied to the secure element rather than to the phone interface.
For buyers comparing Base storage with the wider category, the Cryptnox crypto hardware wallet hub gives broader product context while keeping the same card-based security model in view.
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 a Base Mainnet user, that means the backup is another card from the same set rather than a written recovery phrase by default.
The backup model applies to the Base account in the same way it applies to other networks managed through the app. The two cards are tied to the same seed generated inside their secure elements. If one card is not available, the second card serves as the backup card.
This is a practical fit for Base Mainnet storage because the backup card protects the same Base account key material while private keys remain inside the secure elements. A Base user can focus on selecting Base Mainnet in the app and adding Base ERC-20 tokens when needed, while the second card provides the default backup path.
The Cryptnox app is free on iOS and Android. For Base Mainnet, it is where you select the pre-programmed Base network, manage the native coin of that EVM network, and add Base ERC-20 tokens when needed.
For Web3, Cryptnox connects through WalletConnect and works with MetaMask. That gives a Base user a route for Web3 connections while private keys remain inside the secure element.
The key distinction for Base is that network availability comes first. You do not have to create a custom Base Mainnet entry before using WalletConnect for a Base Web3 connection. Base is already present in the app, and token entries can be handled separately through Add a Token.
If your comparison includes other chain-specific pages, the Polygon hardware wallet page covers another network route, while the Tron hardware wallet page covers Tron separately.
Base Mainnet has a specific advantage in the Cryptnox app: it is already pre-programmed. That is different from an EVM network that is not already listed, because an unlisted EVM network must be added through Add a Network before its native coin and ERC-20 tokens deployed on that chain can be managed.
Base also fits buyers who hold assets across more than one network. You can use the pre-programmed Base route for Base Mainnet, then use Add a Network for another EVM network that is not already present. ERC-20 tokens can be added manually through Add a Token.
Choose the Base route in Cryptnox when you want Base Mainnet already available in the app, Base ERC-20 token addition through Add a Token, Web3 connection through WalletConnect, and a dual-card backup model for the account.
Buyers comparing Base with additional assets can also review the Bitcoin hardware wallet page and the Ronin hardware wallet page. Those pages are useful when the purchase decision is not only about Base Mainnet, but Base remains distinct because it is already pre-programmed in the Cryptnox app.
For a Base-first buyer, the decision point is straightforward: Base Mainnet is present, Base ERC-20 tokens can be added manually, and other EVM networks can still be added later through Add a Network if they are not already listed.
Base Mainnet support is most useful when the hardware model is simple to operate. Cryptnox uses a contact and NFC smart card form factor. For Base, that means you can use the app on a phone and tap the card, or use the contact interface by inserting the card into a reader.
The card itself has no biometric sensor. Unlocking uses the phone’s biometrics through the Cryptnox app. For a Base buyer, the phone provides the app interface and unlock flow, while the smart card keeps private-key generation and retention inside the secure element.
The cards are made in Switzerland, and the product is Swiss-engineered. The Base workflow remains centered on the pre-programmed Base Mainnet route in the app, with the card acting as the hardware device that holds the private keys inside the secure element.
For Base buyers, the important combination is direct Base Mainnet availability, secure-element key generation, and the second card backup. Base is already in the app, private keys are generated inside the secure element and never leave it, and the second card is the backup created during setup.
This combination is especially clear for Base ERC-20 users. The network is already present, so token management begins from the Base Mainnet route rather than from a manual network entry. When a Base-deployed ERC-20 token needs to be shown manually, Add a Token is the relevant app step.
If Base Mainnet is your priority and you want the two-card backup model, buy the Cryptnox Crypto Hardware Wallet – Dual-Card Set.
Yes. Base Mainnet is pre-programmed in the Cryptnox app, so you do not need to add Base manually. Select Base Mainnet in the app, then manage the native coin of that EVM network and ERC-20 tokens deployed on Base.
Yes. ERC-20 tokens can be added through Add a Token. For a Base-deployed ERC-20 token, select Base Mainnet in the app and use the token addition flow when the token needs to be shown manually.
Private keys are generated inside the secure element and never leave it. The card uses an EAL6+-certified chip. The Cryptnox app is the interface for Base activity, while the secure element is where the private keys are generated and retained.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup. By default, the Base backup model does not require writing down a recovery phrase.
No. The card itself has no biometric sensor. Unlocking uses the biometrics on your phone through the Cryptnox app. The card remains a contact and NFC smart card for Base and other supported app routes.
Yes. The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For Base Mainnet, use the pre-programmed Base network in the app, then use the supported Web3 route when a connection is needed.
Yes. Any EVM network can be added through Add a Network. Once added, its native coin and ERC-20 tokens deployed on that chain can be managed. Base is already pre-programmed, so it does not require that network-addition step.
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.
