Keycard and Keycard Shell must work together with a software wallet that supports QR signing. After setting up your Keycard, you need to connect your Keycard Shell to a supported software wallet.

note
Currently, Keycard Shell doesn't always appear on software wallet's list of supported hardware wallets, but you can still connect it to a supported software wallet by selecting the QR-based (for example, MetaMask) or Keystone (for example, Rabby and Nunchuk) option.

  • The software wallet is an interface to manage your crypto assets. The private keys remain on your Keycard, and the software wallet has no access to them.
  • You can connect your Keycard Shell to one or multiple software wallets.
  • You can disconnect Keycard Shell from a software wallet at any time.
  • You can use the software wallet on your phone, computer or browser, depending on what the app supports.

Before connecting to a software wallet, you must select the type of software wallet you want to connect to in Keycard Shell. Here are the options:

  • Ethereum: For software wallets that support Ethereum and EVM-compatible networks, such as MetaMask, Rabby or imToken.
  • Bitcoin: For software wallets that support Bitcoin, such as Sparrow, Specter or Nunchuk.
  • Bitcoin multisig: Select this option to use Bitcoin multisig with the software wallet .
  • Bitcoin testnet: Select this option to use Bitcoin testnet with the software wallet.
  • Multiple blockchains: For software wallets that support multiple blockchains, such as Bitget.
note
Bitcoin multisig and Bitcoin testnet options are for advanced users.

In this process, you use your software wallet to scan a QR code displayed on your Keycard Shell.
