Yes. The Cryptnox Crypto Hardware Wallet – Dual-Card Set can hold ankrETH by adding it as an ERC-20 token on Ethereum. ankrETH is not pre-programmed on the card; add it once through Add a Token or Add a Network using contract 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb. The receiving account uses a 0x-prefixed 20-byte EVM address, and private keys are generated inside the secure element and never leave it.
CRYPTNOX products are also available worldwide through our official Amazon stores.
ankrETH is held on the Cryptnox Crypto Hardware Wallet – Dual-Card Set through its Ethereum ERC-20 token entry, not through a preloaded card setting. The exact Ethereum contract to add is 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb. Ankr describes ankrETH in its Ethereum liquid staking mechanics, and the same token contract is listed on Etherscan for ankrETH.
For this wallet flow, ankrETH should be treated as the ERC-20 token on Ethereum. The token entry is added once through Add a Token or Add a Network, and the receiving account uses an Ethereum address that begins with 0x. The contract address, chain, token standard, and address format should match before receiving ankrETH.
The Dual-Card Set does not arrive with ankrETH already programmed into the wallet view. For this asset, the first asset-specific step after wallet setup is to add the Ethereum ERC-20 token entry with contract 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb. After that entry is added, ankrETH is tied to the Ethereum account shown by the wallet.
The network choice matters because this ankrETH setup is the ERC-20 token on Ethereum. The receiving address should be the Ethereum account address in 0x-prefixed 20-byte EVM format. The contract and network should be treated together: Ethereum for the chain, ERC-20 for the standard, and 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb for the token.
Adding ankrETH does not place the private key in the phone or in the token entry. The token entry identifies an ERC-20 asset on Ethereum; the account control remains tied to the private key generated inside the card’s secure element.
ankrETH is controlled through the Ethereum account that holds the ERC-20 token. On the Cryptnox Dual-Card Set, the private keys for that Ethereum account are generated inside the secure element and never leave it. The visible 0x-prefixed address can be used for receiving ankrETH, while the private key that controls that address remains inside the card.
The chip in each card is an EAL6+-certified chip. That certification applies to the chip, not to the finished card as a wallet product. For ankrETH, the important buyer outcome is that the Ethereum account key is created inside the secure element, while the app is used to add the ankrETH contract and manage the account view.
This separation matters for an Ethereum ERC-20 token. The contract identifies the asset, the Ethereum address identifies the account, and the card’s secure element holds the private key that controls that account.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set ships uninitialised. During setup, the seed is generated inside both cards’ secure elements, so the second card becomes the backup for the same wallet. For ankrETH, that means the backup card protects access to the Ethereum account that controls the ERC-20 token.
No recovery phrase has to be written down by default during the Dual-Card Set setup. The backup is the second card, prepared as part of the same wallet setup. BIP39 recovery phrase import is available as an advanced option, but it is not the default setup path for the card pair.
After the card pair is set up, ankrETH can be added as an Ethereum token entry. The backup card relates to the same underlying wallet because both secure elements were initialised together.
The Cryptnox card is a contact and NFC smart card. You can tap it to a phone when using the mobile app, or insert it into a reader. For ankrETH, that dual-interface form factor gives two ways to work with the same Ethereum account while the private keys remain generated inside the secure element.
The free Cryptnox app is available on iOS and Android. Unlock uses the phone’s biometrics through the Cryptnox app, and the card itself has no biometric sensor. For ankrETH setup, the phone app is where the Ethereum ERC-20 token entry is added with contract 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb.
The card form factor and the ankrETH token entry do different jobs. The smart card protects the account’s private key. The app handles the wallet flow, including adding the ERC-20 token and showing the Ethereum address in 0x-prefixed 20-byte EVM format.
Cryptnox connects to Web3 through WalletConnect and works with MetaMask. For ankrETH, the relevant wallet account is the Ethereum account whose 0x-prefixed address holds the ERC-20 token. The ankrETH contract remains 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb when the token entry is added.
A buyer planning to use ankrETH with connected Ethereum workflows should separate the connection layer from key custody. WalletConnect and MetaMask provide wallet connection routes. The private key for the Ethereum account is generated inside the Cryptnox secure element and never leaves it.
Before adding an ERC-20 token or using the app flow for the first time, the Cryptnox hardware wallet tutorials can help you follow the product setup sequence. For ankrETH specifically, keep the Ethereum network, ERC-20 standard, 0x address format, and contract address aligned during setup.
ankrETH uses Ethereum as its chain and ERC-20 as its token standard. If you are buying a wallet for more than one asset, confirm each asset by network rather than treating all crypto assets as if they use the same address format. The coin and blockchain support page is useful when checking which networks and assets are covered before setup.
The crypto hardware wallet hub is a practical starting point when comparing hardware wallet choices across assets. For ankrETH, the decisive setup details remain Ethereum, ERC-20, the 0x-prefixed EVM address format, and contract 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb.
Other networks have different setup details. If your holdings include Polygon assets, review the Polygon hardware wallet information separately from ankrETH’s Ethereum token entry. If your holdings include TRON assets, use the TRON hardware wallet information for that network rather than applying an ERC-20 contract workflow to it.
Bitcoin and Ronin also require their own network-specific checks. A buyer comparing ankrETH with BTC can review the Bitcoin hardware wallet information, while a buyer comparing ankrETH with RON can review the Ronin hardware wallet information. For ankrETH, use the Ethereum ERC-20 details only.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set is the product to buy when you want the two-card backup model for ankrETH and other supported assets. The cards are made in Switzerland, ship uninitialised, and are set up so the seed is generated inside both secure elements.
For ankrETH, the purchase decision should match the way the asset is actually held: as an Ethereum ERC-20 token added by contract. The card pair gives you a secure-element key model, a second-card backup, and contact plus NFC smart card use. The app gives you the route to add the ankrETH token entry, unlock with the phone’s biometrics, connect through WalletConnect, and work with MetaMask.
No. ankrETH is not pre-programmed on the card. Add it once as an ERC-20 token on Ethereum through Add a Token or Add a Network. Use the contract 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb so the token entry matches ankrETH on Ethereum.
Add ankrETH on Ethereum with contract 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb. The token standard is ERC-20, and the receiving account uses a 0x-prefixed 20-byte EVM address. The contract address is the asset identifier to use during setup.
Yes. ankrETH is held as an ERC-20 token on Ethereum, so the receiving account uses a 0x-prefixed 20-byte EVM address. The address can be used to receive the token, while the private key that controls the Ethereum account is generated inside the secure element.
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 Ethereum account that controls ankrETH. The token remains on Ethereum at its contract address; the backup protects account access.
No. Unlock uses the phone’s biometrics through the Cryptnox app, and the card itself has no biometric sensor. For ankrETH, the app is also where you add the Ethereum ERC-20 token entry and manage the wallet flow.
Yes. The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For ankrETH, use the Ethereum ERC-20 token details and confirm the contract 0xe95a203b1a91a908f9b9ce46459d101078c2c3cb before relying on the token entry.
The Cryptnox product is a contact and NFC smart card. You can tap it to a phone, or insert it into a reader. That same card protects the Ethereum account key used for ankrETH, while the app displays the ERC-20 token entry.
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.
