Yes—the Cryptnox Crypto Hardware Wallet – Dual-Card Set can hold frxETH after you add it once as an Ethereum ERC-20 token or add Fraxtal as an EVM-compatible network. On Ethereum, use contract 0x5e8422345238f34275888049021821e8e08caa1f. On Fraxtal, frxETH is the native gas token. The cards do not arrive with frxETH pre-programmed, and both routes use a 0x-prefixed 20-byte EVM address.
CRYPTNOX products are also available worldwide through our official Amazon stores.
frxETH has two distinct holding routes on the Cryptnox Crypto Hardware Wallet – Dual-Card Set. On Ethereum, it is added as an ERC-20 token. On Fraxtal, it is used as the native gas token of the EVM-compatible Fraxtal network. The card set is not shipped with frxETH already displayed, so the first step is to add the correct token or network route.
The important split is chain role, not address shape. Ethereum frxETH and Fraxtal frxETH both use an EVM account format, so the receiving address is a 0x-prefixed 20-byte address. The difference is that Ethereum uses the ERC-20 contract address, while Fraxtal uses frxETH as the network’s gas asset.
The Frax address documentation lists the Ethereum frxETH token address, and Etherscan shows the same ERC-20 contract. Use the contract address only for the Ethereum token route, not as the way to add Fraxtal.
For buyers checking whether a holding route is available before setup, the Cryptnox coin and blockchain support page is the place to review asset and network coverage before adding frxETH through the Cryptnox app.
When frxETH is held on Ethereum, the token view is tied to the ERC-20 contract 0x5e8422345238f34275888049021821e8e08caa1f. Adding that contract makes the frxETH balance visible for the Ethereum account controlled by the Cryptnox card. The receiving address remains your EVM account address, written as a 0x-prefixed 20-byte address.
Adding the token does not create a separate frxETH-only key. The same Ethereum account key signs the ERC-20 transaction, and that key is created inside the card’s secure element without being exported. The action you perform in the app is an asset-display and transaction-route setup, not a movement of the private key to the phone.
If you are setting up the cards before adding the frxETH contract, the Cryptnox hardware wallet tutorials give the product setup path to follow before adding an EVM token manually.
Fraxtal uses frxETH as its native gas token on an EVM-compatible L2 network. That makes the setup different from Ethereum. For the Fraxtal route, add the Fraxtal network first, then use the account on that network. The Ethereum ERC-20 contract address is for Ethereum token display and is not the Fraxtal network setup step.
The address format stays familiar because Fraxtal is EVM-compatible. A Fraxtal frxETH address is still a 0x-prefixed 20-byte EVM address. The chain selected in the app is what separates a Fraxtal gas-token operation from an Ethereum ERC-20 token transfer.
This chain distinction is especially important because the visible account address can look the same on both EVM routes. Before signing, confirm whether the app is preparing an Ethereum ERC-20 frxETH action or a Fraxtal native frxETH action.
Both supported frxETH routes use EVM addressing, so the account address begins with 0x and represents a 20-byte address. That shared format is convenient, but it also means the address alone does not tell you whether the intended route is Ethereum or Fraxtal. The selected chain must match how the frxETH is being used.
On Ethereum, the account receives frxETH as an ERC-20 token associated with contract 0x5e8422345238f34275888049021821e8e08caa1f. On Fraxtal, the account uses frxETH as the network’s gas token. The same address format can appear in both cases, but the asset role changes with the chain.
If your holdings also include other EVM networks, the Polygon hardware wallet page is useful for comparing another 0x-address network. If your holdings include a different account model, the Tron hardware wallet page helps separate frxETH’s EVM address format from a non-Ethereum-style route.
The key that signs an Ethereum frxETH transfer or a Fraxtal frxETH gas-token operation is generated inside the secure element of the Cryptnox card and is not exported. That matters for frxETH because both routes depend on EVM signing while the asset role changes from ERC-20 token on Ethereum to native gas token on Fraxtal.
The chip platform used for the card includes an EAL6+-certified chip. That certification applies to the chip platform. The finished product is a contact and NFC smart card: for an frxETH transaction, you can tap the card to a phone or insert it into a reader, depending on the workflow you use.
The card has no fingerprint reader and no face sensor. Unlock approval uses the phone’s biometrics through the Cryptnox app, then the card performs the signing step through its contact or NFC interface. For frxETH, that means adding the Ethereum token or Fraxtal network does not turn the phone into the key holder.
The cards are made in Switzerland. For a buyer choosing a card form factor for frxETH, the practical result is a slim smart-card setup for the two supported EVM routes rather than a cable-connected hardware device.
The Dual-Card Set arrives uninitialised. During setup, the seed is generated inside both secure elements, so the second card becomes the backup for the same EVM account that can receive frxETH on Ethereum or use frxETH on Fraxtal. The default setup does not require writing down a recovery phrase.
This is useful for frxETH because the Ethereum and Fraxtal routes can use the same EVM address format. The backup card protects the same account material inside its own secure element, whether the app later displays the Ethereum ERC-20 token contract or the Fraxtal network route.
Importing an existing BIP39 recovery phrase is an advanced option. The default path for the Dual-Card Set is different: the two cards are initialised together, and the second card is the backup from the start.
For frxETH, the free Cryptnox app on iOS and Android is where the practical route is chosen: add the ERC-20 token on Ethereum or add Fraxtal as the EVM network. The app connects to Web3 through WalletConnect and works with MetaMask, so the card-secured account can be used with Ethereum or Fraxtal routes while the signing key remains inside the card.
Network review is the main frxETH habit to keep. If a transaction is prepared on Ethereum, the frxETH asset should correspond to the ERC-20 contract 0x5e8422345238f34275888049021821e8e08caa1f. If it is prepared on Fraxtal, frxETH is being used as the native gas token of that EVM-compatible network.
For buyers comparing Cryptnox across different chain types, the Bitcoin hardware wallet page provides a non-EVM comparison, while the Ronin hardware wallet page gives another network-specific reference. The broader Cryptnox hardware wallet collection is useful when frxETH is only one part of a hardware-wallet shortlist.
The product for the frxETH setup described here is the Cryptnox Crypto Hardware Wallet – Dual-Card Set. It is the two-card smart-card product used for the Ethereum ERC-20 frxETH route and the Fraxtal native gas-token route after the user adds the token or network once.
Choose the Ethereum setup path if your frxETH is the ERC-20 token at 0x5e8422345238f34275888049021821e8e08caa1f. Choose the Fraxtal setup path if your frxETH activity is on the EVM-compatible Fraxtal network, where frxETH is the native gas token. In both cases, the address format is a 0x-prefixed 20-byte EVM address, and the private key stays inside the secure element used by the card.
The product fit is strongest when you want a card-based signing device, a second card as the default backup, and a setup path that keeps Ethereum frxETH and Fraxtal frxETH clearly separated by chain.
No. frxETH is added by the user. Add it as an Ethereum ERC-20 token with contract 0x5e8422345238f34275888049021821e8e08caa1f, or add the Fraxtal network when using frxETH as the native gas token. The cards arrive uninitialised rather than pre-programmed for this asset.
For Ethereum, add frxETH as an ERC-20 token. The contract address is 0x5e8422345238f34275888049021821e8e08caa1f. Your receiving address is a 0x-prefixed 20-byte EVM address controlled by the Cryptnox card, and the token contract is what makes the frxETH balance visible on Ethereum.
On Fraxtal, frxETH is the native gas token of the EVM-compatible Fraxtal network. Add the Fraxtal network route rather than adding the Ethereum ERC-20 contract as the main setup step. The account still uses a 0x-prefixed 20-byte EVM address.
Yes. Ethereum frxETH and Fraxtal frxETH both use a 0x-prefixed 20-byte EVM address format. The address format may look the same, but the chain selection is different: Ethereum uses the ERC-20 token contract, while Fraxtal uses frxETH as native gas.
The key used to sign Ethereum frxETH transfers or Fraxtal frxETH operations is generated inside the card’s secure element and is not exported. Adding the Ethereum token or the Fraxtal network changes how the asset is displayed and routed, not where the signing key is stored.
The Dual-Card Set is initialised with the seed generated inside both secure elements, so the second card is the backup for the same EVM account. That account can be used for frxETH as an Ethereum ERC-20 token or on Fraxtal as the native gas token.
No. The card does not have a fingerprint reader or face sensor. Unlock approval uses the phone’s biometrics through the Cryptnox app, and the card then signs through its contact or NFC smart-card interface.
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.
