Yes. The Cryptnox Crypto Hardware Wallet – Dual-Card Set can hold stETH when you add the stETH ERC-20 token on Ethereum mainnet in the Cryptnox app; stETH is not pre-programmed on the card. Use contract 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84 with an Ethereum 0x-prefixed 20-byte EVM address. Private keys are generated inside the secure element and never leave it, and the second card is the backup.
CRYPTNOX products are also available worldwide through our official Amazon stores.
stETH is held with Cryptnox as an ERC-20 token on Ethereum mainnet. The token is added after wallet setup, not shipped as a pre-programmed asset on the physical card. The contract to add is 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84.
The receiving address for stETH is an Ethereum address: a 0x-prefixed 20-byte EVM address. For deposits, the network is Ethereum mainnet and the asset is the stETH ERC-20 token at the contract above. The address format and the token contract both matter because stETH is not a separate native chain account in this setup.
Lido’s contract documentation lists the Lido stETH token contract at 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84, and Lido’s deployed-contracts documentation lists the same Ethereum mainnet deployment. Use the full contract address when adding the token in the Cryptnox app.
For a broader view of available networks and token routes, review the Cryptnox coin and blockchain support page before adding stETH to the app.
The Cryptnox app is free on iOS and Android. After the Dual-Card Set is initialised, add stETH once in the app through Add a Network or Add a Token. The token to add is stETH on Ethereum mainnet, using contract 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84.
When the app asks for token details, the contract address is the precise identifier for the Ethereum ERC-20 asset. The display name stETH is useful only after the correct Ethereum mainnet contract has been entered. The destination for received stETH is the Ethereum account address controlled by the Cryptnox card set.
The Cryptnox hardware wallet tutorials cover product setup and app flows for card use. Use those instructions together with the stETH contract details above when preparing the wallet for an Ethereum stETH deposit.
After stETH is added, the token is associated with the Ethereum account protected by the Cryptnox secure element. The physical card participates when wallet activity needs approval, while the private key for the Ethereum account stays inside the secure element.
stETH is controlled through an Ethereum account, and that account is controlled by private keys. With the Cryptnox Dual-Card Set, private keys are generated inside the secure element and never leave it. The app provides the interface for the Ethereum account, but the signing key is not exported to the phone.
The card platform uses an EAL6+-certified chip. For an stETH holder, the important boundary is the secure element that creates and retains the Ethereum private key. The EAL6+ property applies to the chip platform, and the card set uses that chip-based security model for account control.
The phone runs the Cryptnox app, shows the account experience, and can use the phone’s fingerprint or face unlock through the app. The card itself has no fingerprint reader or face sensor. The card’s role is to hold the private key inside the secure element and take part in approval when the app requests card use.
For stETH, this separation is important because the receiving Ethereum address can be shared, but the private key behind that address must remain protected. The visible 0x address is not the secret. The private key that controls the Ethereum account is generated inside the secure element and remains there.
Ethereum ERC-20 activity is account based. When the stETH account is used, the card-protected key is the authority behind the address. Keeping that key inside the secure element is the core security model for holding stETH with Cryptnox.
The Cryptnox Crypto Hardware Wallet – 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 stETH, that means the backup protects access to the Ethereum account that holds the ERC-20 token.
This backup model is different from a default paper-writing step. There is no recovery phrase to write down by default. The buyer initialises the two-card set, and both secure elements are part of the wallet creation process. Importing an existing BIP39 recovery phrase is an advanced option, not the default setup.
If stETH is an important holding, treat both cards as parts of the same wallet system. One card can be used day to day, while the second card remains the backup for the same Ethereum account. The Cryptnox Crypto Hardware Wallet – Dual-Card Set shop page is the purchase page for this two-card product.
The stETH token is still added manually after setup. The backup card does not make stETH pre-programmed; it backs up the wallet that controls the Ethereum address where stETH is received.
The Cryptnox card is a contact and NFC smart card. For stETH use, you can tap the card to a phone through NFC or insert it into a reader. The card format does not change the asset route: stETH remains the ERC-20 token on Ethereum mainnet at contract 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84.
When the Cryptnox app is used with the card, the Ethereum account remains tied to the secure element. The phone provides the app interface, and the card is used for approval when required. The receiving address remains the same type of Ethereum 0x-prefixed address used for the stETH account.
The free Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For stETH, that means the card-protected Ethereum account can be used through the app in Web3 flows that rely on WalletConnect or MetaMask.
Before approving any stETH-related action, check that the network is Ethereum mainnet and that the token being handled is the ERC-20 contract listed above. The card protects signing authority for the Ethereum account, while the holder still reviews the address, network, and action shown in the app experience.
stETH does not need a separate address format inside Cryptnox. It uses the Ethereum 0x-prefixed account address because it is an ERC-20 token on Ethereum mainnet.
stETH belongs under the Ethereum ERC-20 route in Cryptnox. If you also hold assets that use different network routes, keep the stETH setup separate in your mind: Ethereum mainnet, ERC-20, contract 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84, and a 0x-prefixed Ethereum address.
That distinction is useful when comparing stETH with pages for other assets. A buyer researching Cryptnox hardware wallet support for Tron is looking at a different asset route from stETH on Ethereum. The same is true when comparing stETH with the Polygon hardware wallet page or the Ronin hardware wallet page.
Bitcoin is also separate from the stETH route. The Cryptnox Bitcoin hardware wallet page covers Bitcoin-focused buying research, while stETH is added in the Cryptnox app as an Ethereum ERC-20 token.
For buyers comparing card-based hardware wallet options across supported assets, the Cryptnox best crypto hardware wallet hub is the parent collection for product and asset pages.
The product for this stETH setup is the Cryptnox Crypto Hardware Wallet – Dual-Card Set. It is a Swiss-engineered contact and NFC smart-card hardware wallet sold at the Cryptnox Dual-Card Set product page.
Buy it for stETH if you want to hold the Ethereum ERC-20 token with private keys generated inside the secure element and kept there. The product is not a pre-loaded stETH card. After initialisation, add stETH in the Cryptnox app with Ethereum mainnet and contract 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84.
The second card is the backup created during setup. That backup model is especially relevant for stETH because the holding depends on continued control of the Ethereum account address. Keep the primary card and backup card under your control, and verify the stETH contract before receiving value.
No. The Cryptnox Crypto Hardware Wallet – Dual-Card Set ships uninitialised, and stETH is not pre-programmed on the card. After setup, add stETH once in the Cryptnox app through Add a Network or Add a Token, using Ethereum mainnet and contract 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84.
Choose Ethereum mainnet. stETH is held with Cryptnox as an ERC-20 token on Ethereum, not as a separate native chain asset. The receiving address is an Ethereum 0x-prefixed 20-byte EVM address, and the token is added with the stETH contract on Ethereum mainnet.
The stETH ERC-20 contract address on Ethereum mainnet is 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84. Use the full address when adding the token in the Cryptnox app. The token route is Ethereum mainnet, ERC-20 standard, and an Ethereum 0x-prefixed receiving address.
The private keys for the Ethereum account are generated inside the secure element and never leave it. The card platform uses an EAL6+-certified chip. The Cryptnox app provides the wallet interface, while the private key controlling the stETH address remains inside the secure element.
The second card in the Dual-Card Set is the backup. The set ships uninitialised, and the seed is generated inside both secure elements during setup. There is no recovery phrase to write down by default. Importing an existing BIP39 recovery phrase is an advanced option.
No. Unlocking can use the phone’s fingerprint or face unlock through the Cryptnox app. The card itself has no fingerprint reader or face sensor. It is a contact and NFC smart card, so it can be tapped to a phone or inserted into a reader.
Yes. The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. For stETH, keep the route on Ethereum mainnet and verify contract 0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84 before approving wallet activity.
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.
