Yes. Binance Smart Chain is pre-programmed in the free Cryptnox app, so a buyer does not need to add that network manually before using the Cryptnox Crypto Hardware Wallet – Dual-Card Set. The same app can add ERC-20 tokens on Binance Smart Chain with Add a Token, connect to Web3 through WalletConnect, and work with MetaMask. During setup, the seed is generated inside both cards’ secure elements, making the second card the backup.

For Binance Smart Chain, the support route is simple: the network is already present in the Cryptnox app. A buyer setting up the Cryptnox Crypto Hardware Wallet – Dual-Card Set for Binance Smart Chain does not start by entering custom network details through Add a Network. That manual route remains available for other EVM networks, but Binance Smart Chain is already in the app before token additions or Web3 use.
This matters most when the wallet is being bought specifically for Binance Smart Chain assets. The native coin of the pre-programmed Binance Smart Chain network can be managed in the app, and ERC-20 tokens deployed on Binance Smart Chain can be added manually with Add a Token. The network and the token are separate steps: the chain is already available, while individual ERC-20 tokens can be added when needed.
The product used for this setup is the Cryptnox Crypto Hardware Wallet – Dual-Card Set. It ships uninitialised, so the Binance Smart Chain setup begins with card initialization in the Cryptnox app rather than with an already-created wallet. During that initialization, the seed is generated inside both secure elements, which makes the second card the backup for the same Binance Smart Chain wallet.
Before buying, buyers who hold assets across several chains can review the Cryptnox coin and blockchain support page to check how Binance Smart Chain sits alongside other supported networks.
Binance Smart Chain users often care about two separate questions: whether the chain is available in the wallet app, and how the wallet is backed up after it is created. Cryptnox answers the first with a pre-programmed Binance Smart Chain network. It answers the second with a Dual-Card Set where both cards are initialized together.
When the Dual-Card Set is prepared, the seed is generated inside both secure elements. The second card is therefore the backup from the initial Binance Smart Chain wallet setup. The default process does not require writing down a recovery phrase. Importing a BIP39 seed of 12 or 24 words is available as an advanced option, but that is not the default path for a new Dual-Card Set.
For a Binance Smart Chain buyer, this backup model keeps the wallet tied to two physical smart cards from the start. The first card can be used for everyday Binance Smart Chain wallet activity through the app, while the second card exists as the backup created during the same initialization process.
Buyers who want the complete setup sequence before managing Binance Smart Chain assets can follow the Cryptnox startup guide before moving on to token additions, WalletConnect, or MetaMask workflows.
When the Cryptnox wallet is set up for Binance Smart Chain, private keys are generated inside the secure element and never leave it. The Binance Smart Chain network appears in the app, but the private keys used by the wallet are created and retained inside the card’s secure element rather than exported into the phone app.
The card uses an EAL6+-certified chip. That chip-level security property belongs to the chip platform inside the smart card. For a Binance Smart Chain buyer, the practical point is that the wallet combines app-level access to a pre-programmed chain with key generation inside the secure element.
The unlock step uses the phone’s face or fingerprint check through the Cryptnox app. The card itself has no sensor for that check. This keeps the Binance Smart Chain workflow split into clear roles: the phone and app provide the user interaction, the card holds the secure element, and the pre-programmed Binance Smart Chain network provides the chain route inside the app.
The app can show the Binance Smart Chain network, add ERC-20 tokens, and connect through WalletConnect or MetaMask. The private keys remain inside the secure element. That separation is the main difference between using the Cryptnox card for Binance Smart Chain and relying on an app-only wallet setup.
The smart card format also affects daily use. The Cryptnox card is a contact and NFC smart card, so it can be tapped to a phone or inserted into a reader. For Binance Smart Chain users who primarily manage assets through a phone, tapping the card to the phone keeps the hardware component close to the mobile app workflow.
Binance Smart Chain support in Cryptnox starts at the network level. Because Binance Smart Chain is pre-programmed in the app, the buyer does not need to create a Binance Smart Chain entry before managing the native coin or adding tokens. Token management then happens separately: ERC-20 tokens deployed on Binance Smart Chain can be added manually through Add a Token.
This distinction avoids mixing two different tasks. Add a Network is for EVM networks that need to be added by the user. Add a Token is for ERC-20 tokens, including ERC-20 tokens deployed on Binance Smart Chain. A buyer focused on Binance Smart Chain can therefore begin from the existing chain entry and add only the tokens that matter to that wallet.
Any EVM network can still be added through Add a Network. Once an EVM network is added, its native coin and ERC-20 tokens deployed on that chain can be managed. Binance Smart Chain is different because the network itself is already prepared in the app.
If the buying decision includes other EVM-style pages, compare this Binance Smart Chain route with the Polygon hardware wallet page and the Ronin hardware wallet page. Binance Smart Chain stands out in this group because it is already pre-programmed in the Cryptnox app.
The free Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For Binance Smart Chain, that means the buyer can use the pre-programmed network in the app and still have a Web3 route when a Binance Smart Chain workflow requires WalletConnect or MetaMask interaction.
The card and app have different roles in that workflow. The app provides the Binance Smart Chain interface, WalletConnect route, and MetaMask use. The card provides the secure element where the private keys are generated and kept. Binance Smart Chain does not need to be added as a custom EVM network before that Web3 path is considered.
This is especially relevant for buyers who plan to use Binance Smart Chain beyond simple asset viewing. The wallet can start with the chain already available in the Cryptnox app, then add ERC-20 tokens on Binance Smart Chain with Add a Token, and then use WalletConnect or MetaMask when Web3 access is needed.
Buyers comparing Binance Smart Chain with non-EVM needs can also use the best crypto hardware wallet collection and the Bitcoin hardware wallet page to separate Binance Smart Chain requirements from Bitcoin-specific requirements.
The Cryptnox card is a dual-interface smart card for Binance Smart Chain use: tap it to a phone with the Cryptnox app, or insert it into a reader. The phone route is useful when working from the mobile app, where Binance Smart Chain is already available and ERC-20 tokens can be added manually.
Because the app is available on iOS and Android, Binance Smart Chain setup can begin on either mobile platform. The card remains the hardware component in the process, while the app provides the Binance Smart Chain network entry, token addition route, WalletConnect, and MetaMask use.
The cards are made in Switzerland, and the product is Swiss-engineered. For a Binance Smart Chain buyer, the relevant purchase details are the pre-programmed chain route, the dual-card backup model, and the contact plus NFC smart card format. Those three points shape how the wallet is initialized, backed up, and used with the app.
If your Binance Smart Chain holdings are part of a wider chain comparison, the Tron hardware wallet page is useful for comparing a separate chain path against the EVM-based route used for Binance Smart Chain and other EVM networks.
Yes. Binance Smart Chain is pre-programmed in the free Cryptnox app. A buyer does not need to add the Binance Smart Chain network with Add a Network before using it. ERC-20 tokens deployed on Binance Smart Chain can be added separately with Add a Token.
Use Add a Token in the Cryptnox app for ERC-20 tokens deployed on Binance Smart Chain. The network itself is already present, so token addition is separate from network setup. Other EVM networks use Add a Network first, then their native coin and ERC-20 tokens can be managed.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both cards' secure elements, so the second card becomes the backup for the same wallet. The default setup does not require writing down a recovery phrase, while importing a BIP39 seed of 12 or 24 words is an advanced option.
Private keys are generated inside the secure element and never leave it. The Cryptnox app provides the Binance Smart Chain network, token addition, WalletConnect, and MetaMask routes, while the card remains the place where the private keys are created and retained.
Yes. The free Cryptnox app works with MetaMask and connects to Web3 through WalletConnect. Binance Smart Chain is already pre-programmed in the app, so the Web3 path can be used without first adding Binance Smart Chain as a manual EVM network.
No. Unlocking uses the phone's face or fingerprint check through the Cryptnox app. The card itself has no sensor for that step. The card is a contact and NFC smart card, and its secure element is where the private keys are generated and kept.
Yes. Any EVM network can be added through Add a Network. After an EVM network is added, its native coin and ERC-20 tokens deployed on that chain can be managed. Binance Smart Chain is different because it is already pre-programmed in the Cryptnox app.
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.
