Cryptnox supports SKALE (SKL) by letting you manually add the Ethereum SKL token in the Cryptnox app. Add SKL as the Ethereum token at contract 0x00c83aeCC790e8a4453e5dD3B0B4b3680501a7A7. Bridged ERC-20 SKL on EVM SKALE chains may also be holdable when the relevant network and token are manually added. SKL uses an 0x-prefixed 20-byte EVM address.
CRYPTNOX products are also available worldwide through our official Amazon stores.
SKL is holdable with Cryptnox through the Ethereum token route. Add the token manually in the Cryptnox app after the Dual-Card Set is initialised. Use Ethereum as the chain and enter the SKL contract 0x00c83aeCC790e8a4453e5dD3B0B4b3680501a7A7. The token is not pre-programmed, so the setup step matters before you expect an SKL balance to appear.
The SKALE documentation describes SKL as the SKALE token, and the Ethereum contract can be checked on Etherscan. In the Cryptnox app, the contract identifies the SKL token on Ethereum, while the selected network determines which token balance is shown.
For the broader Cryptnox asset list, review the coin and blockchain support page before adding SKL manually in the app. That check helps you separate the SKL token route from any other EVM asset you may already use.
After the Dual-Card Set is initialised, add SKL through the app’s token-add flow. Select Ethereum for the main SKL route, then enter the SKL contract. The account shown for SKL uses the same 0x-prefixed 20-byte EVM address format used by Ethereum accounts, but the SKL token entry still depends on the contract being added correctly.
SKL should be added once for the Ethereum token route. If the token does not appear before this step, create the SKL token entry in the wallet interface. The card protects the account keys, and the app needs the token contract to show the Ethereum SKL balance.
If you want to review the general card setup before adding the SKL contract, the Cryptnox hardware wallet tutorials provide the starting point for initialisation and app use. Complete the card setup first, then add SKL as a token entry under Ethereum.
SKL on Ethereum and bridged ERC-20 SKL on an EVM SKALE chain are separate wallet entries. The Ethereum SKL route uses the Ethereum network and the Ethereum contract. A bridged ERC-20 SKL route may be holdable when the relevant EVM SKALE network and the bridged token are manually added.
Adding the Ethereum SKL contract does not create a SKALE-chain token entry. For bridged ERC-20 SKL, add the network first when it is not already present, then add the token for that network. The address format remains EVM-style, but the selected network still controls which token balance is displayed.
This distinction is useful if you already manage other EVM assets. A Polygon hardware wallet setup also uses EVM-style addressing, but SKL requires its own Ethereum contract and any SKALE-chain token must be added under the relevant EVM SKALE network.
When the Cryptnox Dual-Card Set is set up for SKL, the private keys for the EVM account are generated inside the secure element and never leave it. The SKL token entry in the app points to an Ethereum or EVM SKALE-chain token balance, while control of the account remains tied to keys kept inside the card’s secure element.
The card uses an EAL6+-certified chip. That certification belongs to the chip platform. For SKL, the relevant outcome is that the Ethereum token route and any manually added EVM SKALE-chain route use accounts controlled by keys generated and retained 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. There is no recovery phrase to write down by default. Importing an existing BIP39 seed is an advanced option, not the default path for a new SKL setup.
That backup model fits SKL because the asset is added after initialisation. The card pair is created first, the shared backup relationship is established inside the two secure elements, and the SKL token entry is then added to the wallet interface with the correct Ethereum contract or manually configured SKALE-chain token details.
The Cryptnox Crypto Hardware Wallet – Dual-Card Set is a contact and NFC smart card product. For SKL, the same card can be tapped to a phone for the Cryptnox app workflow or inserted into a reader for contact-card use.
The Cryptnox app is free on iOS and Android. SKL setup happens in the app because the token is added manually: Ethereum for the main SKL token route, or a manually added EVM SKALE network plus token when using bridged ERC-20 SKL on that network.
Unlocking through the Cryptnox app can use the phone’s biometrics. The card itself has no biometric sensor. SKL account control still depends on the card-controlled account: the app provides the interface, while the private keys are generated inside the secure element and never leave it.
For shoppers comparing card-based storage across assets, the best crypto hardware wallet collection gives the broader Cryptnox hardware wallet context.
The Cryptnox app connects to Web3 through WalletConnect and works with MetaMask. For SKL, the network selected in the Web3 flow must match the SKL token route you added in the app. Ethereum SKL belongs under Ethereum, while bridged ERC-20 SKL belongs under the manually added EVM SKALE network used for that bridged token.
Before using SKL with a Web3 connection, check the token entry rather than only the address. EVM networks can share the same 0x-style address format, so the network and token contract determine which SKL balance is being used.
If you also use assets with different address assumptions, treat them separately. A TRON hardware wallet setup does not use the same SKL contract route, and a Bitcoin hardware wallet setup uses a different address model from SKL’s EVM address format.
Choose the Dual-Card Set for SKL if you want to hold the Ethereum SKL token through a card-based hardware wallet and add the asset yourself in the app. The product is sold as the Cryptnox Crypto Hardware Wallet – Dual-Card Set, and SKL is added after initialisation rather than arriving as an existing token entry.
The SKL purchase decision has three concrete parts. First, SKL is added as the Ethereum token at 0x00c83aeCC790e8a4453e5dD3B0B4b3680501a7A7. Second, bridged ERC-20 SKL on an EVM SKALE chain requires the relevant network and token to be added manually. Third, the account keys are generated inside the secure element and stay there.
The cards are Swiss-engineered contact and NFC smart cards. The second card acts as the backup because the seed is generated inside both secure elements during initialisation. Once that setup is complete, add SKL in the Cryptnox app using the Ethereum contract, or add the relevant EVM SKALE-chain network and bridged token if that is the SKL route you intend to hold.
No. SKL is added manually in the Cryptnox app after card initialisation. For the main route, add SKL as the Ethereum token using contract 0x00c83aeCC790e8a4453e5dD3B0B4b3680501a7A7. Bridged ERC-20 SKL on EVM SKALE chains may also be holdable when the relevant network and token are manually added.
Add the Ethereum SKL token contract 0x00c83aeCC790e8a4453e5dD3B0B4b3680501a7A7. The main SKL route on Cryptnox is SKL on Ethereum, using ERC-777 on Ethereum with ERC-20-compatible handling. The wallet address format is an 0x-prefixed 20-byte EVM address.
Bridged ERC-20 SKL on EVM SKALE chains may be holdable if the relevant network and token are manually added. Add the EVM SKALE network first when needed, then add the bridged SKL token for that network. This is separate from adding the Ethereum SKL token.
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 seed is an advanced option.
Private keys for the SKL account are generated inside the secure element and never leave it. The card uses an EAL6+-certified chip, with the certification applying to the chip platform. The SKL token entry in the app displays the asset route; the keys remain inside the card.
No. The card itself has no biometric sensor. Unlocking through the Cryptnox app can use the phone’s biometrics. For SKL, the app handles the Ethereum token entry or manually added EVM SKALE-chain token entry, while the private keys remain inside the secure element.
Yes. The free Cryptnox app on iOS and Android connects to Web3 through WalletConnect and works with MetaMask. Add SKL first as the Ethereum token, or manually add the relevant EVM SKALE network and bridged ERC-20 SKL token before using that SKL route.
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.
