Yes. The Cryptnox Crypto Hardware Wallet – Dual-Card Set can hold EUR CoinVertible as Ethereum ERC-20 EURCV and as the XRP Ledger issued-currency representation after you add the token or network in the Cryptnox app. EURCV is not pre-programmed on the cards. The Solana and Stellar representations are not holdable routes for this setup. Private keys are generated inside the secure element and never leave it.
CRYPTNOX products are also available worldwide through our official Amazon stores.
EUR CoinVertible is a multi-chain asset, but the Cryptnox setup for EURCV is specific. The holdable routes are Ethereum ERC-20 EURCV and the XRP Ledger issued-currency representation. The Solana token and Stellar token representations are not the routes to add for this card setup.
EURCV is not pre-programmed on the cards. Add it once through Add a Network or Add a Token in the Cryptnox app, then use the route details that match the chain you selected. On Ethereum, the address is an 0x-prefixed 20-byte EVM address. On the XRP Ledger, the asset is identified by an issuer r-address, currency, and trustline.
The Cryptnox coin and blockchain support page is the right place to check how supported asset routes are organised before adding EURCV. SG-FORGE presents EUR CoinVertible under the EURCV name, which matches the asset name used for the Ethereum ERC-20 route.
The Ethereum route treats EUR CoinVertible as the ERC-20 EURCV token. The receiving address is an Ethereum-style account address: 0x-prefixed and 20 bytes in EVM format. Add the token before expecting EURCV to appear as a manageable asset in the Cryptnox app flow.
Do not use XRP Ledger issuer or trustline details for the Ethereum route. ERC-20 EURCV belongs to the Ethereum account path, and the visible account address should match the 0x format used by EVM accounts. If the destination details are not an 0x-prefixed EVM address, they are not the Ethereum ERC-20 route described here.
For another EVM-focused page, the Cryptnox Polygon hardware wallet page is useful when the route question is Polygon rather than Ethereum ERC-20 EURCV. Keep the network route separate from the token name when you prepare a receive address.
The XRP Ledger route is not an ERC-20 token route. EUR CoinVertible is handled as an issued currency on XRPL, with an issuer r-address, a currency identifier, and a trustline. The asset is not identified by an Ethereum token contract pattern on this route.
When you add EUR CoinVertible through the XRP Ledger path, check the issuer r-address and trustline information rather than looking for a 0x-prefixed EVM address. The relevant account format and asset relationship are different from the Ethereum ERC-20 route, even though both routes refer to EUR CoinVertible.
SG-FORGE has published a note on SGF CoinVertible on the XRP Ledger, which supports the distinction between the XRPL issued-currency route and the Ethereum ERC-20 route. If your wallet task is native XRP rather than EUR CoinVertible issued on XRPL, treat that as a separate asset question.
Start with the route, not only the ticker. If you want Ethereum EURCV, add the Ethereum ERC-20 token route and verify the 0x-prefixed address. If you want the XRP Ledger issued-currency representation, add the issuer r-address, currency, and trustline details required for that route.
The free Cryptnox app runs on iOS and Android. It is the interface for adding EURCV and for using WalletConnect or MetaMask flows where those are needed. The card remains the signing device for the EURCV account route you choose.
Use the Cryptnox hardware wallet tutorials when you want the product walkthrough before adding EURCV. The tutorial path is especially relevant when you are setting up the two-card backup before receiving the asset.
For EUR CoinVertible, the security question is the same on both holdable routes: which device controls the account key used to sign the transaction. In the Dual-Card Set, the Ethereum and XRP Ledger account keys are created within the smart card secure element and are not exported from it.
Each card uses an EAL6+-certified chip. For EURCV holders, that chip-level assurance sits at the point where the private account key is generated and used. The card is not a software-only wallet on the phone; the phone app provides the interface while the smart card handles the protected key operation.
Unlocking the EURCV workflow uses the phone’s face or fingerprint check through the Cryptnox app. The card itself does not contain a fingerprint reader or face sensor. That distinction matters when comparing the physical card with phone-only wallet use: the phone confirms the user step, and the card protects the account key.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set is the product to choose when EURCV is being held with the second card as the backup card. The cards are Swiss-engineered contact and NFC smart cards.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup for the same EURCV account setup. The default flow does not require writing recovery words on paper before you can use the backup card.
This matters for both holdable EUR CoinVertible routes. If you add ERC-20 EURCV on Ethereum, the second card backs up the account key behind that Ethereum route. If you add the XRP Ledger issued-currency representation, the same paired-card setup backs up the account key used for that XRPL route.
For a buyer whose main holding is EURCV, the practical decision is whether to keep the supported route clear and the backup card stored separately from daily use. The product design makes the backup another card in the set rather than a separate default paper process.
The Cryptnox card is dual-interface: tap it to a phone by NFC, or insert it into a contact reader. That applies whether you are managing Ethereum ERC-20 EURCV or the XRP Ledger issued-currency representation. The card format is not tied to only one of those chain routes.
For a phone flow, the Cryptnox app on iOS or Android provides the EURCV interface and prompts for the card when the signing step requires it. For a contact flow, the card is inserted into a reader. In both cases, the route details still matter: Ethereum uses the 0x-prefixed address format, while XRPL uses issuer, currency, and trustline details.
If you are comparing EURCV with assets on other networks, use chain-specific pages rather than mixing address formats. The Cryptnox Tron hardware wallet page is for a Tron route, and the Cryptnox Ronin hardware wallet page is for a Ronin route. For the broader category, the Cryptnox hardware wallet collection hub helps place EURCV alongside other hardware wallet use cases.
No. EUR CoinVertible is not pre-programmed on the Cryptnox Crypto Hardware Wallet – Dual-Card Set. After the two cards are initialised, add EURCV once through Add a Network or Add a Token. The holdable routes for this setup are Ethereum ERC-20 EURCV and the XRP Ledger issued-currency representation.
Add EUR CoinVertible as the Ethereum ERC-20 EURCV token. The receive address for this route is an 0x-prefixed 20-byte EVM address. Do not use XRP Ledger issuer or trustline information for the Ethereum route, because XRPL issued currency uses a different identification model.
On the XRP Ledger, EUR CoinVertible is an issued-currency representation. The identifying details are the issuer r-address, the currency identifier, and the trustline. This is not the same as the Ethereum ERC-20 route, which uses an 0x-prefixed EVM address for the account.
Not with this Cryptnox EURCV setup. The holdable routes are Ethereum ERC-20 EURCV and the XRP Ledger issued-currency representation. EUR CoinVertible also exists as a Solana token and a Stellar token, but those representations are not the routes to add here.
Yes. Cryptnox ships worldwide from the official CRYPTNOX store. Orders to Switzerland, the European Union and the United States are dispatched from stock already held in each of those regions, so the parcel does not cross a customs border into your country and there are no import duties to pay. Orders to other destinations are shipped internationally, and any import duties or local taxes are set by the destination country and are the recipient’s responsibility. Current shipping rates are shown at checkout.
The Dual-Card Set starts uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup card. That backup applies to the account route used for Ethereum ERC-20 EURCV or the XRP Ledger issued-currency representation.
No. The card itself has no fingerprint reader or face sensor. Unlocking the EURCV workflow uses the phone's face or fingerprint check through the Cryptnox app, while the card protects the account key inside its secure element.
Yes. The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For EURCV, first add the correct holdable route, such as Ethereum ERC-20 for the 0x-address flow. The card remains the hardware key holder during the wallet connection flow.
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.
