The BitBox02 Bitcoin-only edition exclusively supports Bitcoin.
The BitBox02 Multi edition supports Bitcoin, Litecoin, Cardano, Ethereum and ERC-20 tokens.
A selection of ERC-20 tokens are available in the BitBoxApp, which can be enabled within the BitBoxApp settings.
All other ERC-20 tokens need to be accessed via MyEtherWallet.
A list of all currently supported coins & tokens can be found here: https://bitbox.swiss/coins/
As each additional blockchain requires firmware changes and ongoing maintenance, we currently do not have any plans to add more coins in the near future.
