Describe the problem:
Automatic Syncing of Yoroi Wallet using Public HD Key
Which exchange/wallet is this regarding?
Yoroi
How did you import data into this wallet?
Automatic Sync
What have you tried to fix this so far?
Tried resyncing.
Basically if I setup Yoroi wallet for my cardano using Public HD key, it shows 0 transactions. Is there any way to fix this?
Hi!
Alex from Koinly here 
For Cardano you need to use an xpub key instead of the public one.
If the xpub key is not showing any transactions then please double check it first on https://explorer.cardano.org/en and see there are any transactions showing.
If there’s none then the issue is on Yoroi’s side.
If you see transactions in the explorer but it’s not syncing to Koinly then please contact us via the chat when you are logged in or by sending an email to hello@koinly.io so we can provide more direct support.
Best regards,
Alex
