Yes. The Cryptnox Crypto Hardware Wallet – Dual-Card Set can hold Liquity USD (LUSD) as an ERC-20 token on Ethereum after you add the token once. LUSD is not pre-programmed on the card. Add it through Add a Token, or Add a Network when needed, using contract 0x5f98805A4E8be255a32880FDeC7F6728C6568bA0. Your LUSD receiving address is a 0x-prefixed 20-byte EVM address.
CRYPTNOX products are also available worldwide through our official Amazon stores.
Liquity USD (LUSD) is held with Cryptnox through the Ethereum ERC-20 route. The card secures the Ethereum account that controls the LUSD balance, and the token is identified in the wallet interface by its Ethereum contract address: 0x5f98805A4E8be255a32880FDeC7F6728C6568bA0.
LUSD is not a separate Cryptnox card mode and it is not pre-programmed before setup. After your Cryptnox wallet is set up, add Liquity USD once as an Ethereum token. The receiving address for LUSD is the Ethereum-style account address shown by the wallet: a 0x-prefixed 20-byte EVM address.
Liquity v1 documentation identifies LUSD within the Liquity v1 protocol, and Liquity’s launch announcement states that Liquity went live on Ethereum mainnet. For a wallet buyer, the setup route is therefore specific: add LUSD as the Ethereum ERC-20 token, not as an asset on another network.
The Cryptnox card does not arrive with Liquity USD already visible in the app. Add LUSD once before using the wallet as your receiving address. In the Cryptnox app or a Web3 route, use Add a Token for the Ethereum ERC-20 contract. Use Add a Network when that step is required before the token can be displayed.
The token entry should match Ethereum and the LUSD contract exactly. The Ethereum account address stays the same 0x-prefixed address; the contract tells the interface that the balance to display is Liquity USD rather than another ERC-20 token connected to the same account.
The Cryptnox hardware wallet tutorials are the product guidance for setup steps after purchase. For LUSD, the important setup result is a Cryptnox-secured Ethereum account with the Liquity USD ERC-20 contract added once.
Holding LUSD means controlling the Ethereum account that owns the ERC-20 token balance. With the Cryptnox Crypto Hardware Wallet – Dual-Card Set, the private key for that Ethereum account is generated inside the secure element and never leaves it. LUSD transactions are approved through the wallet flow while the private key remains protected inside the card.
The chip platform used in the card includes an EAL6+-certified chip. That property belongs to the chip platform. For LUSD custody, the practical security point is that the Ethereum private key is created inside the secure element, stays inside it, and is used there when the card authorizes account activity.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card becomes the backup for the same wallet. In the default setup flow, there is no recovery phrase to write down. Importing a 12- or 24-word BIP39 recovery phrase is an advanced option rather than the normal path for a new Dual-Card Set.
That backup model is directly relevant to Liquity USD because the second card backs up the Ethereum account that controls the LUSD token balance. The backup card is created during the same setup process and protects the same wallet.
The free Cryptnox app is available on iOS and Android. For Liquity USD, the app is where you manage the card, add the Ethereum ERC-20 token, and confirm activity for the Ethereum account that holds LUSD. Unlocking uses the phone’s face or fingerprint check through the Cryptnox app; the card itself has no fingerprint reader.
The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For LUSD holders, that means the Ethereum account protected by the card can be used through those routes while the private key remains generated and stored inside the card’s secure element.
For buyers checking the exact product, the Cryptnox Crypto Hardware Wallet – Dual-Card Set is the two-card product described here for LUSD custody.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set is a contact and NFC smart card. For Liquity USD, that means the same card can be tapped to a phone during app use or inserted into a reader when a contact smart card setup is preferred. The card is the signing device for the Ethereum account that controls the LUSD ERC-20 balance.
The dual-interface card format matters during LUSD setup because adding the token is an app or Web3 interface action, while account security remains tied to the private key inside the card. The LUSD token entry does not move the private key into the phone. It gives the interface the Ethereum contract needed to display Liquity USD for the 0x address.
The product is Swiss-engineered and sold as a Dual-Card Set. For an LUSD buyer, the relevant purchase outcome is a two-card setup in which the second card is created as the backup during initialization, and the Ethereum account secured by those cards can hold LUSD after the ERC-20 contract is added.
The Cryptnox crypto hardware wallet collection gives wider product context for buyers who want the same smart card format for more than Liquity USD.
LUSD in this setup is the ERC-20 token on Ethereum. Use the Ethereum contract 0x5f98805A4E8be255a32880FDeC7F6728C6568bA0 and a 0x-prefixed Ethereum account address. Do not treat Liquity USD as a separate chain inside the wallet, and do not expect an LUSD-only address format.
The Cryptnox coin and blockchain support page is useful before purchase when LUSD is only one of the assets you plan to hold. It helps you check the wider asset route while keeping the LUSD requirement clear: Ethereum, ERC-20, and the Liquity USD contract.
If you also hold assets on Polygon, the Cryptnox Polygon hardware wallet page covers that separate network route. LUSD here remains tied to Ethereum, even though both routes can involve 0x-style EVM addresses.
If you also hold TRON assets, the Cryptnox TRON hardware wallet page is the relevant comparison because TRON is not the Ethereum ERC-20 route used for LUSD. Buyers who also hold Bitcoin can review the Cryptnox Bitcoin hardware wallet page, where the address model is different from LUSD’s 0x-prefixed Ethereum account.
On this product, Liquity USD custody is account custody. The ERC-20 token balance is associated with an Ethereum account, and the Cryptnox card protects the private key for that account. Adding the LUSD contract tells the app or Web3 interface which token balance to show for the same 0x-prefixed address.
This distinction matters when preparing to receive LUSD. The card does not need an LUSD-only address, and it does not ship with the LUSD token already displayed. The buyer’s setup task is to initialize the Dual-Card Set, open the Ethereum route, add the Liquity USD token contract, and verify the 0x address before receiving funds.
Once those details match, the Cryptnox-secured Ethereum account is the account that receives and controls LUSD. The private key remains inside the secure element, and the token entry remains the Ethereum ERC-20 contract associated with Liquity USD.
Choose the Cryptnox Crypto Hardware Wallet – Dual-Card Set for Liquity USD if you want LUSD held through an Ethereum account whose private key is generated inside the card’s secure element. The product is sold as two smart cards, ships uninitialised, and creates the backup card during setup by generating the seed inside both secure elements.
Initialize the Dual-Card Set, add Liquity USD as an Ethereum ERC-20 token, and verify the 0x-prefixed address before receiving funds. The token is not pre-programmed, so the LUSD contract entry is part of preparing the wallet for use.
For LUSD, the buying decision comes down to the Ethereum ERC-20 route, the 0x address format, and the two-card backup model. After setup, the card-secured Ethereum account is the account that receives and controls Liquity USD.
No. LUSD is not pre-programmed on the card. Add Liquity USD once as an Ethereum ERC-20 token using contract 0x5f98805A4E8be255a32880FDeC7F6728C6568bA0. After the token is added, the LUSD balance is tied to the Ethereum account controlled by your Cryptnox card.
Choose Ethereum for the LUSD route described here. Liquity USD is held as an ERC-20 token on Ethereum, and the receiving address is a 0x-prefixed 20-byte EVM address. The token should be added with the Ethereum contract address for LUSD.
LUSD uses a 0x-prefixed 20-byte EVM address because the supported route is ERC-20 on Ethereum. The address is the Ethereum account secured by the Cryptnox card. The LUSD contract identifies which token balance is displayed for that account.
Yes. The Dual-Card Set ships uninitialised, and setup generates the seed inside both secure elements. The second card is the backup for the same wallet, including the Ethereum account that controls your LUSD. The default setup does not require writing down a recovery phrase.
Yes. The free Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For LUSD, those routes use the Ethereum account protected by the Cryptnox card while the private key remains generated and stored inside the secure element.
No. Unlocking uses the phone’s face or fingerprint check through the Cryptnox app. The card itself has no fingerprint reader. Its role is to protect the Ethereum private key inside the secure element and authorize activity for the account that holds LUSD.
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.
