Known issues:

• Transaction signing is limited to 6 x 6, i.e. no more than six inputs or six outputs in any one given transaction.
• Need to generate Cardano Ada addresses on the device in order to counter publicly known attacks like this.
• Wallet key derivation algorithms differ between Ledger and Cardano. Need to align derivation. Until then, Daedalus/Cardano user with a Ledger wallet will need a Nano S in order to restore/move funds.
• Fees displayed during transaction signing are always 0.00 currently. Waiting for fee to be sent across with Tx, which will be implemented on the Cardano SL.
