Zcash blockchain provides increased privacy by implementing shielded (z) addresses – due to this, Zcash workflow differs from transparent networks, such as Bitcoin.

When you import a wallet with transactions that occurred over 10 000 blocks before the import time, use the "Update all blocks" button to retrieve correct tx history and balance value. 

This process takes a long time. This is a background process and you can minimise the app, but do not close it completely. The balance will be updated at the end of the sync process. While the synchronisation is in progress, operations with your wallet in the app will not be available. This only affects our app and not your real balance.

After blockchain sync has finished you will see the correct balance in the interface. In case your balance is still incorrect, please contact Guarda Wallet customer support line.
