Yes. Cryptnox supports EigenCloud (EIGEN) as an Ethereum ERC-20 token that you add once in the Cryptnox app or through MetaMask. EIGEN is not pre-programmed on the card. Use Ethereum and the contract address 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83, then receive to your own 0x Ethereum address. The Dual-Card Set keeps the private keys inside secure elements, with the second card serving as the backup.
CRYPTNOX products are also available worldwide through our official Amazon stores.
EigenCloud (EIGEN), formerly EigenLayer, is held with Cryptnox as an ERC-20 token on Ethereum. That detail decides the setup: EIGEN is not a separate chain inside the wallet, and it is not already shown on the card when the Dual-Card Set arrives. You add the token once, using the Ethereum contract address 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83.
The current EigenCloud listing is shown on CoinMarketCap’s EigenCloud page, and the ERC-20 token contract is visible on Etherscan at 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83. Those two details are the useful buyer checks: the asset name is EigenCloud, the ticker is EIGEN, and the token you add is the Ethereum ERC-20 contract at that address.
For an EIGEN holder, the receiving address is the Ethereum account controlled by the Cryptnox card. The token contract identifies EIGEN itself; it is not the address you give to someone who is sending you EIGEN. The result is a normal Ethereum-token custody setup: EIGEN is displayed through the wallet interface, while the account keys remain with the card.
EIGEN requires one manual token step because it is not pre-programmed as a visible card asset. In the Cryptnox app or in MetaMask, add EIGEN as an Ethereum ERC-20 token. If your interface asks for a network first, use Ethereum. If it asks for a token contract, enter 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83.
The most common EIGEN setup mistake is mixing up two different 0x values. The EIGEN contract address is the public Ethereum smart-contract address for the token. Your receiving address is your own Ethereum account address, also beginning with 0x, controlled by the private keys in the Cryptnox secure element. The contract address makes EIGEN visible; your account address receives the token.
Adding EIGEN does not change where the keys live. The token entry tells the interface which ERC-20 balance to show for the Ethereum account. The private keys controlling that account are generated inside the secure element and never leave it.
An EIGEN balance on Ethereum is controlled by the private keys for the Ethereum account that holds it. With the Cryptnox Crypto Hardware Wallet – Dual-Card Set, those private keys are generated inside the secure element and never leave it. The app, MetaMask, and WalletConnect can present EIGEN information, but the key custody for the Ethereum account remains on the card.
Cryptnox uses an EAL6+-certified chip for the secure-element platform. The finished product is a contact and NFC smart card, while the EAL6+ property belongs to the chip. For EIGEN buyers, the practical point is that the token balance is not secured by the token display itself; it is secured by the hardware-controlled Ethereum account that signs for that address.
This distinction matters when EIGEN is added manually. A token can be made visible in more than one interface, but visibility is not custody. The Cryptnox card holds the private keys for the Ethereum account; the EIGEN contract address only tells the interface which ERC-20 token balance to read for that account.
If EIGEN is one of several Ethereum assets in the same account, the same 0x address can show more than one ERC-20 balance after the relevant tokens are added. The protection model still follows the account key: the secure element controls the Ethereum address, and the EIGEN balance follows that address.
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 wallet. For EIGEN, that means both cards can control the same Ethereum account that holds the ERC-20 token after the token has been added to the interface.
By default, the Dual-Card Set does not ask you to write down a recovery phrase. The backup is the second smart card, created during the same setup process. Importing a 12 or 24 word BIP39 recovery phrase is an advanced option, not the default route for a new Dual-Card Set.
EIGEN is displayed through an Ethereum token contract, but access depends on the Ethereum account keys. If the primary card cannot be used, the second card is already tied to the same seed generated during setup. After adding or viewing the EIGEN token through the wallet interface, the backup card can still control the same 0x account.
This is especially useful for an ERC-20 token that is added manually. If you replace an app interface or add EIGEN again through MetaMask, the token display can be recreated from the contract address. The hard-to-replace item is the Ethereum account key, and that is what the two-card setup protects.
The free Cryptnox app is available on iOS and Android. For EIGEN, the app is the place to work with the Ethereum account controlled by the card and to add the ERC-20 token when it is not already visible. The app can also connect to Web3 through WalletConnect, and Cryptnox works with MetaMask.
MetaMask is useful for EIGEN when you want an Ethereum interface that can show a custom ERC-20 token. Add EIGEN with the contract address 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83, confirm Ethereum as the network, and check that the account shown is the 0x address controlled by your Cryptnox card.
The Cryptnox app can use the phone’s own face or fingerprint unlock as part of opening the app experience. The card itself has no fingerprint or face sensor. That matters because phone unlock and card signing are different steps: the phone helps you access the app, while the card protects and uses the private keys for the Ethereum account that holds EIGEN.
For wallet handling beyond the EIGEN contract details, the Cryptnox hardware wallet tutorials are the practical place to review app and card operations before adding the token to your Ethereum account.
The Cryptnox wallet is a contact and NFC smart card. You can tap the card to a phone, or insert it into a smart-card reader. For EIGEN, that gives two ways to bring the same Ethereum account into use while keeping the account’s private keys inside the secure element.
On mobile, the important EIGEN details are simple to verify before receiving or approving activity: Ethereum network, EigenCloud name, EIGEN ticker, contract address 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83, and your own 0x Ethereum receiving address. With a reader workflow, the same asset details apply because EIGEN remains the same Ethereum ERC-20 token.
The cards are Swiss-engineered and sold as the Cryptnox Crypto Hardware Wallet – Dual-Card Set. If your EIGEN purchase is part of a broader Ethereum-token setup, the Cryptnox coin and blockchain support page helps you check how other networks and assets are handled before you decide what to add alongside EIGEN.
EIGEN is a good match for buyers who want Ethereum ERC-20 custody with a smart-card hardware format, manual token entry by contract address, and a second card as the backup. The purchase decision is not whether EIGEN is preloaded; it is whether you want the Ethereum account keys for EIGEN generated inside secure elements and kept there.
If your wallet will hold more than EIGEN, compare how each asset’s chain and address format differs before sending funds. EIGEN uses an Ethereum 0x address as an ERC-20 token. Bitcoin uses a different address model, so the Bitcoin hardware wallet page is useful when your portfolio includes BTC as well as EIGEN. Polygon is relevant when you are comparing EVM-style address workflows, and the Polygon hardware wallet page gives that network its own treatment.
For buyers building a multi-chain self-custody plan, the Cryptnox hardware wallet collection hub is the starting point for choosing the smart-card wallet category. If EIGEN is being held alongside other chain-specific assets, the Tron hardware wallet page and the Ronin hardware wallet page help separate those address and network decisions from the Ethereum ERC-20 setup used for EIGEN.
No. EIGEN is not pre-programmed as a visible asset on the card. Add EigenCloud (EIGEN) once as an Ethereum ERC-20 token in the Cryptnox app or through MetaMask, using contract address 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83.
Use Ethereum for this EIGEN token. EigenCloud (EIGEN) is held as an ERC-20 token on Ethereum, so the receiving address is your own 0x-prefixed 20-byte EVM address controlled by the Cryptnox wallet setup.
No. The EIGEN contract address identifies the ERC-20 token: 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83. Your receiving address is your own Ethereum 0x account address. Use the contract address when adding the token, and use your account address when receiving EIGEN.
The Dual-Card Set ships uninitialised, and the seed is generated inside both secure elements during setup. The second card is therefore the backup for the same Ethereum account that can hold EIGEN after the ERC-20 token is added to the wallet interface.
No. The private keys for the Ethereum account that controls EIGEN are generated inside the secure element and never leave it. The Cryptnox app, WalletConnect, or MetaMask can show the account and token, while the card remains the signing device.
Yes. Cryptnox works with MetaMask. Use MetaMask as an Ethereum interface, add EIGEN with the contract address 0xec53bF9167f50cDEB3Ae105f56099aaaB9061F83 if it is not visible, and make sure the account is the Ethereum 0x address controlled by your Cryptnox card.
No. The card itself has no fingerprint or face sensor. Unlocking can use the phone’s own face or fingerprint check through the Cryptnox app, while the card remains the secure signing device for the Ethereum account that holds EIGEN.
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.
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.
