Yes. Bitcoin is supported natively on Bitcoin Mainnet in the free Cryptnox app, so you do not need to add the network manually. The Cryptnox Crypto Hardware Wallet – Dual-Card Set supports Legacy P2PKH Bitcoin addresses starting with 1 and SegWit bech32 addresses starting with bc1. For a new Dual-Card Set, the seed is generated inside both secure elements during setup, making the second card the backup.
CRYPTNOX products are also available worldwide through our official Amazon stores.
Bitcoin Mainnet is already pre-programmed in the Cryptnox app. A buyer choosing the Cryptnox Crypto Hardware Wallet – Dual-Card Set for Bitcoin does not need to create a custom Bitcoin network entry before using the card with the app.
That native route is the main Bitcoin-specific setup difference to understand. The app recognises Bitcoin Mainnet as a supported network, and the Bitcoin support detail covers both Legacy and SegWit address formats. Legacy means P2PKH addresses that start with 1, while SegWit means bech32 addresses that start with bc1.
For a wider view of supported assets, the Cryptnox coin and blockchain support page is the relevant place to review Bitcoin Mainnet alongside other listed networks.
The Bitcoin support detail is native and format-specific: Legacy P2PKH and SegWit bech32 are supported in the Cryptnox app. That gives a Bitcoin buyer a concrete way to match the wallet route with the address style they plan to use.
Legacy P2PKH Bitcoin addresses start with 1. SegWit bech32 Bitcoin addresses start with bc1. Those prefixes matter because they are visible before a buyer sends Bitcoin to an address or checks which Bitcoin address family an account is using.
This page is about Bitcoin, so the address examples are Bitcoin address examples rather than token contract examples or manually added chain examples. A buyer checking Bitcoin support should confirm the Bitcoin network route and the Bitcoin address family, because both are named in the Cryptnox app support detail.
The address-format point also separates Bitcoin use from Web3 connection features in the app. The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask, while Bitcoin support is handled through the app’s native Bitcoin Mainnet route.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set ships uninitialised. During the first setup, the seed for the Bitcoin-capable wallet is generated inside both secure elements, so the second card becomes the backup for the wallet created in that setup.
The default Dual-Card Set flow does not require writing down a recovery phrase. For a Bitcoin buyer, that means the backup is not a separate paper step in the standard setup; it is the second smart card initialised with the first card. Importing an existing BIP39 recovery phrase with 12 or 24 words is available as an advanced option, but it is not the default setup path for a new Dual-Card Set.
A buyer setting up Bitcoin for the first time should follow the Cryptnox startup guide for the app and card initialisation flow. The official purchase route for the two-card backup model is the Cryptnox Crypto Hardware Wallet – Dual-Card Set product page.
For Bitcoin use, the important custody point is that the private keys are generated inside the secure element and never leave it. The Bitcoin Mainnet route is handled in the Cryptnox app, while the Bitcoin private keys remain tied to the secure element inside the card.
The card uses an EAL6+-certified chip. That certification is a property of the chip platform, not a claim about the finished card. The practical result for a Bitcoin buyer is a clear split between the app interface and the place where the Bitcoin private keys are created and kept.
This distinction matters when comparing a Bitcoin hardware wallet with app-only storage. The Cryptnox app is part of the Bitcoin workflow, but Bitcoin private keys are not generated by the phone and are not exported from the secure element.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set uses a contact and NFC smart card format. For Bitcoin use with a phone, the card can be tapped to the phone. For a contact reader setup, the same card can be inserted into a reader.
This dual-interface design gives a Bitcoin buyer two physical ways to present the card while keeping the same native Bitcoin Mainnet route in the Cryptnox app. The card is not limited to one presentation method, and Bitcoin support remains the same whether the card is tapped to a phone or inserted into a reader.
Buyers comparing card-based storage across the Cryptnox hardware wallet collection can treat Bitcoin support as a native Bitcoin Mainnet app route paired with this contact and NFC smart card format.
Bitcoin support in the Cryptnox app is native to Bitcoin Mainnet. The same app also connects to Web3 through WalletConnect and works with MetaMask, which is useful for buyers who want one Cryptnox app environment while checking asset support one network at a time.
A Bitcoin buyer who also reviews Tron support can use the Cryptnox hardware wallet for Tron page for that separate network. A buyer comparing Bitcoin with Polygon support can use the Cryptnox hardware wallet for Polygon page before deciding how to organise assets in the app.
For portfolios that include other named assets, the Cryptnox hardware wallet for Ronin page and the Cryptnox hardware wallet for USD Coin page provide asset-specific routes. For Bitcoin itself, the key support facts remain Bitcoin Mainnet, Legacy P2PKH addresses starting with 1, and SegWit bech32 addresses starting with bc1.
The Cryptnox wallet is not a hierarchical-deterministic (HD) wallet. For Bitcoin it presents one fixed receive address, and every incoming transaction goes to that same address. There is no automatic or manual address rotation, and the app provides no way to derive, select or switch to a different Bitcoin address.
This is worth knowing before buying, because it differs from multi-address Bitcoin wallets:
The card itself derives keys along BIP32 and SLIP-10 paths, with one derivation path per supported chain, so the constraint is in what the app exposes rather than in the chip.
Rotating to a fresh address for every deposit is the standard Bitcoin privacy practice, and it does do something: an observer looking at one address alone sees less. The question is how much that is worth once the coins move, and what it costs to maintain.
One derivation path per chain and one address. Recovery is deterministic: there is no path to guess and no gap limit to scan, and the seed already exists in the second card’s secure element. The design favours getting your funds back over making a single address harder to look up.
That is a trade, not a free win. If address-level privacy is a real requirement for you – and for some people it genuinely is – a multi-address wallet such as Sparrow or Electrum is the better tool, and you should use one.
A Bitcoin hardware wallet decision should be based on the Bitcoin network route, the Bitcoin address formats, the way the backup is created, and where the Bitcoin private keys are generated. The Cryptnox Crypto Hardware Wallet – Dual-Card Set gives a specific answer to each of those points.
For buyers whose priority is Bitcoin Mainnet support with the Dual-Card Set backup model, the official shop listing is the Cryptnox Crypto Hardware Wallet – Dual-Card Set.
Yes. Bitcoin Mainnet is pre-programmed in the Cryptnox app, so you do not need to add the Bitcoin network manually. The Bitcoin support is native and covers Legacy P2PKH addresses starting with 1 and SegWit bech32 addresses starting with bc1.
Cryptnox supports Bitcoin Legacy and SegWit address formats in the app. Legacy support means P2PKH Bitcoin addresses that start with 1. SegWit support means bech32 Bitcoin addresses that start with bc1. Both are part of the native Bitcoin Mainnet support route.
Yes. The Dual-Card Set ships uninitialised, and the seed is generated inside both secure elements during setup. Because the same setup creates both cards, the second card is the backup for the Bitcoin-capable wallet created in that process.
No. The default Dual-Card Set setup uses the second card as the backup, because the seed is generated inside both secure elements. Importing an existing BIP39 recovery phrase with 12 or 24 words is an advanced option rather than the default setup path.
Bitcoin private keys are generated inside the secure element and never leave it. The card uses an EAL6+-certified chip, with that certification applying to the chip platform. The Cryptnox app provides the Bitcoin Mainnet route while key generation and key storage stay inside the secure element.
The Cryptnox wallet is a contact and NFC smart card. For phone use, you tap the card to the phone. For reader use, you insert the card into a reader. Bitcoin Mainnet remains the pre-programmed app route in either card presentation method.
No. The card itself has no biometric sensor. Unlock approval can use the biometrics on your phone through the Cryptnox app, while the Bitcoin private keys remain inside the secure element on the smart card.
No. The Cryptnox wallet is not an HD wallet. For Bitcoin the app uses one fixed receive address, and the same address is used for every incoming transaction. There is no address rotation, automatic or manual, and the app has no interface to derive, select or switch to another Bitcoin address. This differs from multi-address Bitcoin wallets such as Sparrow or Electrum, which rotate receive addresses for privacy.
At the cryptography layer the card does derive keys along BIP32 and SLIP-10 paths, with one derivation path per supported chain. That derivation is not exposed in the app as multi-address management.
It makes your Bitcoin history easier to follow on a public explorer than a rotating wallet would. In practice the gap is smaller than it sounds: spending several UTXOs together links them anyway, and coins withdrawn from a KYC exchange are already tied to you. Cryptnox trades that for a recovery path with no derivation path to guess and no gap limit to scan. If address-level privacy is a firm requirement, use a multi-address wallet such as Sparrow or Electrum.
