Yes. Cryptnox can hold Curve DAO Token as manually added CRV on Ethereum, using the ERC-20 contract 0xD533a949740bb3306d119CC777fa900bA034cd52. CRV is not pre-programmed on the card, so add it once through Add a Token, or use Add a Network first if your setup requires it. The receiving address is a 0x-prefixed 20-byte EVM address, and the private keys are generated inside the secure element and never leave it.
CRYPTNOX products are also available worldwide through our official Amazon stores.
Curve DAO Token is held on Cryptnox as CRV on Ethereum. It is not a pre-programmed card asset. The route to use is the Ethereum ERC-20 token contract 0xD533a949740bb3306d119CC777fa900bA034cd52, received to a 0x-prefixed 20-byte EVM address controlled by the Cryptnox wallet.
The Curve documentation for CRV identifies CRV as the Curve DAO token, and the CRV token page on Etherscan shows the Ethereum contract address used for this ERC-20 route. Use the contract address, not the ticker alone, when adding the token manually.
If you want to compare the CRV route with assets that are listed differently, review the Cryptnox coin and blockchain support page before buying. For this page, the buyer decision is specific: use the Dual-Card Set for the Ethereum key that controls the CRV address, then add the CRV contract manually in the wallet interface.
CRV is added after the Dual-Card Set is initialised. In the wallet interface, choose Add a Token and enter Curve DAO Token as an Ethereum ERC-20 token with contract 0xD533a949740bb3306d119CC777fa900bA034cd52. If your setup first asks for the relevant Ethereum path, use Add a Network before adding the token contract.
The token entry is the wallet interface’s way of reading and using the CRV contract for your Ethereum address. It does not create a separate CRV-only private key. The same 0x-prefixed Ethereum address controls the ERC-20 token route.
The Cryptnox hardware wallet tutorials are useful before adding CRV manually, because this asset depends on entering the Ethereum token route correctly rather than selecting a pre-set card entry. Once CRV is added, the wallet interface can use that entry for later CRV display and transaction flows.
The name “Curve DAO Token” and the ticker “CRV” are labels. The Ethereum contract address is the detail that identifies this token route. Before receiving CRV, confirm that the token entry points to 0xD533a949740bb3306d119CC777fa900bA034cd52 and that the selected chain is Ethereum.
This matters because the Cryptnox card protects the Ethereum private key, while the manually added token entry tells the wallet interface which ERC-20 contract to use. If the interface is missing the CRV contract, the Ethereum address still exists, but the CRV display and interaction route may not be present until the token is added.
If you hold assets alongside CRV, compare chain and address details rather than assuming they work the same way. The Cryptnox hardware wallet for Polygon covers a different network route, while the Cryptnox hardware wallet for Bitcoin uses a different address model from CRV’s 0x-prefixed Ethereum format.
CRV does not require a separate CRV-only key. It is controlled through the Ethereum address that holds the ERC-20 token. On the Cryptnox Dual-Card Set, private keys are generated inside the secure element and never leave it. The manually added CRV entry identifies the token contract; the card protects the key that controls the 0x address.
The secure element uses an EAL6+-certified chip. For a CRV holder, that means the chip platform protecting the Ethereum private key is evaluated at that level, while CRV remains an Ethereum ERC-20 token entry in the wallet interface.
When CRV is sent, the wallet action is an Ethereum ERC-20 token transaction involving the CRV contract address. The card’s role is to use the private key for the Ethereum account without exposing that key to the phone, app screen, or token list.
Unlocking uses the phone’s face or fingerprint check through the Cryptnox app. The card itself has no fingerprint reader or face sensor. For CRV, the phone handles the user unlock step, and the card remains the secure element that controls the Ethereum key used with the CRV contract.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set ships uninitialised. During setup, the wallet seed is generated inside both secure elements, so the second card becomes the backup for the same Ethereum address used to hold CRV. There is no recovery phrase to write down by default.
This backup model matters for CRV because the token entry and the private key are different things. The Ethereum private key controls the 0x-prefixed address. The CRV contract entry tells the wallet interface which ERC-20 token to show and use. If the token entry has to be added again, the CRV contract can be entered again; the address depends on the seed protected in the cards.
For a CRV buyer, the practical sequence is simple: initialise both cards, confirm the Ethereum address format, add the CRV contract, and keep the second card as the backup card for the same wallet.
The Cryptnox card is a contact and NFC smart card. For CRV, you can tap the card to a phone when the app requests card interaction, or insert the card into a reader when using the contact interface. The access method changes how the card is read; it does not change CRV’s Ethereum ERC-20 contract route.
The free Cryptnox app is available on iOS and Android. For CRV, the important app task is adding the Ethereum token contract once, then using the card-protected Ethereum address for receiving or sending the token.
The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. Use those routes with the Ethereum address controlled by the card after adding Curve DAO Token as the ERC-20 contract 0xD533a949740bb3306d119CC777fa900bA034cd52. The Web3 connection is the interaction route; the private key remains inside the secure element.
This distinction helps avoid a setup mistake. CRV is not stored as a separate file or preset on the card. The card protects the Ethereum key, and the manually added CRV entry points the wallet interface to the token contract that belongs to that Ethereum address.
The CRV setup described here uses the Cryptnox Crypto Hardware Wallet – Dual-Card Set. Buy it if you want a card-based Ethereum hardware wallet route for Curve DAO Token, with a second card created as the backup during setup. The cards are Swiss-engineered, and CRV is added manually after initialisation.
The buyer path is specific: initialise the Dual-Card Set, use the Ethereum address controlled by the cards, add CRV as an ERC-20 token with contract 0xD533a949740bb3306d119CC777fa900bA034cd52, and then use that route for receiving or sending CRV. The card protects the Ethereum key; the CRV entry identifies the token contract.
If you are still comparing asset routes before buying, the Cryptnox hardware wallet collection groups buyer pages by asset. CRV should be treated as Ethereum ERC-20. Other pages, such as the Cryptnox hardware wallet for Tron and the Cryptnox hardware wallet for Ronin, cover different network routes, not the Ethereum CRV contract route.
No. CRV is not pre-programmed on the card. Add Curve DAO Token manually as an ERC-20 token on Ethereum, using contract 0xD533a949740bb3306d119CC777fa900bA034cd52. Use a 0x-prefixed 20-byte EVM address for the CRV receiving route.
Use the Ethereum CRV contract address 0xD533a949740bb3306d119CC777fa900bA034cd52. The chain is Ethereum, the token standard is ERC-20, and the wallet address format is a 0x-prefixed 20-byte EVM address. Check the full contract rather than relying on the ticker.
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 Ethereum address that can hold CRV. There is no recovery phrase to write down by default.
The private keys are generated inside the secure element and never leave it. For CRV, those keys control the Ethereum 0x address that holds the ERC-20 token. The manually added CRV contract entry tells the wallet interface which token to display and use.
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.
Yes. The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For CRV, first add Curve DAO Token manually as the Ethereum ERC-20 token with contract 0xD533a949740bb3306d119CC777fa900bA034cd52, then use the card-controlled Ethereum address.
No. Unlocking uses the phone’s face or fingerprint check through the Cryptnox app. The card itself has no fingerprint sensor. For CRV, the card’s role is to protect the Ethereum private key inside the secure element while the app handles the user unlock step.
Importing an existing BIP39 recovery phrase is an advanced option, not the default setup. The default Dual-Card Set setup generates the seed inside both secure elements, making the second card the backup for the Ethereum address used with CRV.
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.
