Yes. The Cryptnox Crypto Hardware Wallet – Dual-Card Set supports SSV Network as an ERC-20 token on Ethereum after you add it once through Add a Network or Add a Token. SSV is not pre-programmed on the card. Use contract address 0x9D65fF81a3c488d585bBfb0Bfe3c7707c7917f54 with an Ethereum 0x-prefixed address. The Ethereum account keys are generated inside the secure element and never leave it.
CRYPTNOX products are also available worldwide through our official Amazon stores.
SSV Network is held on the Cryptnox Crypto Hardware Wallet – Dual-Card Set through Ethereum ERC-20 token support. It is not a pre-programmed asset on the card, so an SSV buyer should plan to add the token once during setup or before receiving SSV.
The SSV setup route is specific: select Ethereum, add SSV as an ERC-20 token, and enter the token contract 0x9D65fF81a3c488d585bBfb0Bfe3c7707c7917f54. The SSV Network smart-contract documentation is the external reference to use when confirming the official contract address before entering it in a wallet flow.
Your SSV receiving account on Cryptnox is an Ethereum account. That means the address follows the 0x-prefixed 20-byte EVM address format, not a separate SSV-only address format. The token entry tells the app which ERC-20 balance to display for that Ethereum account.
If you are comparing SSV Network with other assets before buying, the Cryptnox coin and blockchain support page helps you review asset routes across the Cryptnox product line.
SSV custody on Cryptnox depends on entering the Ethereum token details correctly. The card does not arrive with an SSV mode already prepared, so the first SSV-specific action is to add the ERC-20 token entry. Once that entry is present, the relevant account is still the Ethereum account controlled by the cards.
This checklist matters because an ERC-20 token is located by its contract on Ethereum, while the receiving account uses the Ethereum address format. For SSV, the contract identifies the asset and the 0x address identifies the account that holds it.
The SSV Network introduction describes SSV Network in the context of Ethereum validator infrastructure. That Ethereum context matches the Cryptnox setup path: SSV is handled as an Ethereum ERC-20 token, not as a standalone card preset.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set ships uninitialised. For a new SSV holder, the wallet is created during your own setup before you add SSV as an Ethereum token. The SSV token entry is not what creates the wallet; it is the ERC-20 entry that points the app to the SSV balance for the Ethereum account controlled by the cards.
The setup order is important because the second card is created as the backup during the same wallet initialisation. For SSV, this means the backup card protects the Ethereum account that will hold the ERC-20 token after SSV has been added. You do not need to write down a recovery phrase by default for a new Dual-Card Set. Importing an existing BIP39 recovery phrase is available as an advanced option, but that is not the normal path for a new SSV setup.
For product walkthroughs while pairing the app, preparing the card set, or connecting wallet tools for an SSV Ethereum account, use the Cryptnox hardware wallet tutorials alongside the SSV contract details on this page.
When SSV is held on Cryptnox, the protected item is the private key for the Ethereum account that controls the ERC-20 token balance. Those private keys are generated inside the secure element and never leave it. The SSV token entry can be added in the app, but the key material for the 0x account is created and kept inside the card’s secure element.
The card uses an EAL6+-certified chip. For SSV custody, that chip is the protected environment where the Ethereum account keys are generated and retained. The certification applies to the chip platform, while the SSV-relevant custody model is that the ERC-20 token is controlled by keys that are not exported from the secure element.
For an SSV transfer or Ethereum wallet action, the phone handles the biometric check through the Cryptnox app. The card itself has no biometric sensor. This distinction matters because the phone is used for the approval experience, while the smart card remains the device that holds the Ethereum account keys for SSV.
The card is a contact and NFC smart card. In an SSV workflow, you can tap the card to a phone when using the mobile app, or insert it into a reader when that is the chosen card interaction. This dual-interface form factor is useful for ERC-20 holders who want a card-based wallet for the Ethereum account that holds SSV.
The free Cryptnox app is available on iOS and Android. After SSV has been added as an Ethereum ERC-20 token, the app connects to Web3 through WalletConnect and works with MetaMask. The SSV-specific part of that flow is the account and token selection: the account should be the same 0x-prefixed Ethereum address that holds the SSV token entry.
This matters because WalletConnect and MetaMask interactions can involve many Ethereum assets. For SSV, the contract address defines the token, and the Ethereum address defines the account. The Cryptnox card controls the private keys for that Ethereum address; the app and connection flow provide the interface for using the account.
SSV should not be treated as a separate native network setting on the card. The product route is Ethereum ERC-20 support, with the card protecting the Ethereum account keys and the app showing the SSV token once it has been added.
The Dual-Card Set backup model is especially relevant for SSV because the token is tied to an Ethereum account. During initialisation, the seed is generated inside both secure elements. The second card is the backup for the same wallet, so the backed-up account is the Ethereum account that can receive and hold SSV after the ERC-20 token is added.
For a new SSV wallet, this keeps the backup path separate from writing down a recovery phrase by default. The buyer sets up two cards together, then adds the SSV token entry for the Ethereum account. If the token entry has to be added again in an app view, the underlying wallet backup remains the paired second card created during initialisation.
The backup is not a separate SSV token setting. The backup is the wallet seed created inside both secure elements, which controls the Ethereum account used for SSV. The ERC-20 token entry tells the app to recognize SSV at its contract address, while the paired cards protect access to the account that holds it.
The cards are made in Switzerland. Combined with the card-based backup model, the SSV setup is straightforward: initialise the two cards, add SSV as an Ethereum ERC-20 token, then receive SSV to the 0x-prefixed Ethereum address controlled by the Dual-Card Set.
SSV has a narrower support path than assets that use their own native address format. On Cryptnox, the SSV route is Ethereum plus ERC-20 plus the SSV contract address. If you are deciding whether the Dual-Card Set matches the mix of assets you hold, start with the Cryptnox hardware wallet hub and then compare the individual asset routes that matter to your portfolio.
For example, a buyer who holds TRON as well as SSV should review the Cryptnox hardware wallet for TRON page because that asset route is separate from the Ethereum ERC-20 path used by SSV. A buyer who holds Polygon assets can compare SSV’s Ethereum token setup with the Cryptnox hardware wallet for Polygon page.
If your holdings include assets outside the SSV and EVM-token category, the Cryptnox hardware wallet for Bitcoin guide and the Cryptnox hardware wallet for Ronin guide show how other asset pages separate chain, account format, and setup route. For SSV, the buyer decision is to use the Dual-Card Set for the Ethereum account that holds SSV as an ERC-20 token.
No. SSV is not pre-programmed on the Cryptnox Crypto Hardware Wallet – Dual-Card Set. Add it once through Add a Network or Add a Token, select Ethereum as the chain, use ERC-20 as the token standard, and enter the SSV contract address.
Use 0x9D65fF81a3c488d585bBfb0Bfe3c7707c7917f54 for SSV on Ethereum. Because SSV is held as an ERC-20 token, the contract address identifies the token and the receiving account is an Ethereum 0x-prefixed 20-byte EVM address.
No. SSV uses the Ethereum address format on Cryptnox because it is held as an ERC-20 token on Ethereum. The receiving address begins with 0x, and the SSV token entry is defined by the ERC-20 contract address.
The private keys for the Ethereum account that can hold SSV are generated inside the secure element and never leave it. The SSV token entry is added in the app, while the card protects the keys that control the 0x-prefixed account.
The Dual-Card Set ships uninitialised, and the seed is generated inside both secure elements during setup. The second card is the backup for the Ethereum account that can hold SSV after the token is added. A recovery phrase is not written down by default.
Yes. The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. After adding SSV as an Ethereum ERC-20 token, use the same 0x-prefixed Ethereum account when connecting through those flows.
No. The phone handles the biometric check through the Cryptnox app, and the smart card itself has no biometric sensor. For SSV use, the card remains the device holding the Ethereum account keys while the phone provides the approval interface.
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.
