Cardano now supports UTXOs (like bitcoin). We should support syncing all UTXO addresses using the public root key.
Note: IOHK does not yet robustly support getting your public root key from ADA wallet (e.g. Yoroi, Daedalus).
Until we are able to support adding these wallets via xPub sync, you can add Yoroi and Daedalus transactions using a CSV import. These are a custom imports we've designed for these wallets, so you can upload CSV as-is with no need to format it.
To add your transactions, go to Wallets > Add Wallet, search for Daedalus or Yoroi, then follow the instructions shown.
