Yes. The Cryptnox Crypto Hardware Wallet – Dual-Card Set can hold weETH as an Ethereum ERC-20 token when you add contract 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee in the Cryptnox app. weETH is not pre-programmed on the card. Add it once through Add a Network or Add a Token, then use the Ethereum 0x-prefixed 20-byte EVM address format. Private keys are generated inside the secure element and never leave it.
CRYPTNOX products are also available worldwide through our official Amazon stores.
weETH is held with Cryptnox through its Ethereum ERC-20 token contract, not through a pre-programmed asset profile on the card. The contract to add is 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee, and the holding address uses the 0x-prefixed 20-byte EVM format used on Ethereum.
The Etherscan token page for weETH identifies weETH at the same Ethereum contract address. ether.fi describes weETH as wrapped eETH in its weETH help article. For a Cryptnox buyer, the practical route is to add the Ethereum ERC-20 token once, then use the card-controlled Ethereum address for that token.
The important buying distinction is that the card protects the Ethereum key that controls the address. It does not arrive with weETH already enabled, and it does not need a separate weETH-only account type once the Ethereum ERC-20 token has been added.
Control of weETH depends on control of the Ethereum address that can hold the ERC-20 token. In the Cryptnox Crypto Hardware Wallet – Dual-Card Set, private keys are generated inside the secure element and never leave it. The card protects the private key for the 0x-prefixed Ethereum address used with the weETH contract.
The card contains an EAL6+-certified chip. That certification applies to the chip platform, while the finished product is a contact and NFC smart card used with the Cryptnox app. The security model is centered on keeping the private key inside the secure element instead of placing it on the phone.
This matters for weETH because the token contract and the holding address are different pieces of information. The contract identifies weETH on Ethereum. The card-controlled Ethereum address is the address that can hold the token. Cryptnox protects the key for that address.
The free Cryptnox app is available on iOS and Android. To use weETH, open the app and add the Ethereum ERC-20 token once through Add a Network or Add a Token. Enter contract 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee and use the Ethereum 0x-prefixed address format for the holding address.
If you want to review the product setup flow before adding the weETH contract, the Cryptnox hardware wallet tutorials cover how the wallet is set up and used with the app. For a broader check of asset and chain routes handled by Cryptnox, the coin and blockchain support page is the place to verify support paths.
Because weETH is not pre-programmed on the card, the contract entry is the step that makes the token visible for use in the app. The card’s role is to keep the private key for the Ethereum address inside the secure element.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup. For weETH, that means the backup is tied to the Ethereum address that can hold the ERC-20 token, not to a separate weETH file or a token-specific password.
There is no recovery phrase to write down by default. Importing an existing BIP39 phrase with 12 or 24 words is available as an advanced option, but it is not the default path for a new Dual-Card Set. The default design is that both cards are initialised together, with the second card serving as the backup.
The second card backs up the key material created inside the secure elements. After weETH is added as the Ethereum ERC-20 token at 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee, the relevant address is still the Ethereum address controlled by that key material. The token contract identifies weETH; the cards protect access to the address that can hold it.
This backup model is useful for a manually added token such as weETH because the token setup and the key backup are separate concerns. Adding the contract makes weETH visible in the app. Initialising the two cards creates the backup relationship for the Ethereum key.
The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For weETH, the asset detail to keep consistent is the Ethereum ERC-20 contract 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee. The connection route may involve WalletConnect or MetaMask, while the asset itself remains the Ethereum token added in the Cryptnox app.
Before using a Web3 service with a Cryptnox-controlled address for weETH, check that the service is presenting Ethereum and the weETH contract above. The address should be the 0x-prefixed 20-byte EVM address controlled by the Cryptnox card. The private key remains generated inside the secure element and never leaves it.
weETH is an Ethereum ERC-20 token, so it should not be treated as a TRON asset or a Polygon-native asset when adding it to Cryptnox. If you are setting up assets on those different routes, use the dedicated Cryptnox pages for TRON hardware wallet support and Polygon hardware wallet support instead of reusing the weETH contract details.
The Cryptnox wallet is a contact and NFC smart card. You can tap it to a phone or insert it into a reader. For weETH, the phone and app handle the Ethereum ERC-20 token setup, while the card protects the private key for the address that can hold the token.
Unlocking uses the phone’s biometric check through the Cryptnox app. The card itself has no biometric sensor. The card remains a smart-card signing device with a secure element; the phone provides the app interface for adding the weETH contract and working with WalletConnect or MetaMask.
The product sold for this setup is the Cryptnox Crypto Hardware Wallet – Dual-Card Set. It is Swiss-engineered and sold as two smart cards, with the second card serving as the backup after initialisation.
If your purchase decision is specifically about a card-based hardware wallet for an Ethereum ERC-20 position such as weETH, the Cryptnox hardware wallet collection gives the product-family context before you choose the Dual-Card Set. weETH itself still uses the Ethereum ERC-20 route and the contract address listed on this page.
Before moving weETH to an address controlled by your Cryptnox card, confirm that you are using Ethereum, the ERC-20 standard, and contract 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee. The holding address should be a 0x-prefixed 20-byte EVM address.
Do not use weETH’s Ethereum contract as if it were a Bitcoin or Ronin address. Bitcoin uses a different asset route, and Ronin has its own route. If those assets are part of your setup, review the dedicated Cryptnox pages for Bitcoin hardware wallet support and Ronin hardware wallet support. For weETH, the relevant path is Ethereum ERC-20.
The result is a specific support path for weETH: add the Ethereum ERC-20 contract in the app, hold the token at the card-controlled Ethereum address, and use the second smart card as the backup created during initialisation.
No. weETH is not pre-programmed on the card. Add it once in the Cryptnox app through Add a Network or Add a Token. Use Ethereum as the chain, ERC-20 as the standard, and contract 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee.
Add the Ethereum ERC-20 weETH contract 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee. The holding address uses the 0x-prefixed 20-byte EVM address format. Check both the Ethereum network and the exact contract before using the address for weETH.
The card protects the private key for the Ethereum address that can hold weETH. weETH is an ERC-20 token on Ethereum, so control depends on the key behind the address. With Cryptnox, that private key is generated inside the secure element and never leaves it.
The Dual-Card Set ships uninitialised. During setup, the seed is generated inside both secure elements, so the second card is the backup. There is no recovery phrase to write down by default. Importing an existing BIP39 phrase with 12 or 24 words is an advanced option.
Yes. The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. For weETH, keep the asset route consistent: Ethereum, ERC-20, and contract 0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee.
No. Unlocking uses the phone’s biometric check through the Cryptnox app. The card itself has no biometric sensor. Its role is to protect the private key inside the secure element and work with the app for the Ethereum address that can hold weETH.
The Cryptnox wallet is a contact and NFC smart card. You can tap it to a phone or insert it into a reader. In the weETH setup, the app adds the Ethereum ERC-20 contract, and the smart card protects the private key for the 0x-prefixed address.
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.
