23. Derive the Address Holding Funds: In Zecwallet, click on “Receive” and select “Transparent.” Then, in Ledger Live, click on the tool icon at the top right and select “Edit account."
24. Copy the Fresh Address Path: Under “Advanced,” locate the “FreshAddressPath” and copy the address displayed.
25. Add Two Addresses in Zecwallet: Return to Zecwallet and add two addresses as shown in the provided image.
26. Rescan the Chain for Balance: Ready? Initiate a rescan of the blockchain to reveal the account balance.
27. View Your Updated Balance: After the scan completes, you should see the updated balance reflecting your unlocked funds.
28. Transfer Funds (Optional): To move funds back, locate the original address in Ledger Live, The one you wanted to move your funds to in the first place (while the app crashed, and you could not do it), copy it, and paste it into Zecwallet's “Send” section. Enter the amount and send.
29. Confirm on Your Device: Use your Ledger to approve the transaction. Once completed, you’ll see a confirmation message in Zecwallet.
30. Verify on the Explorer: Copy the transaction ID and paste it into the Explorer for confirmation.
31. Wait until confirmed
32. Check Updated Ledger Balance: Once the transaction confirms, review your Ledger balance to see the updated amount.
And that’s it! You’ve successfully unlocked and managed your Zcash funds with the Shielded App on Ledger.
This might feel a bit technical, but following these steps gives you full control over your Zcash with peace of mind. Now you’re ready to enjoy the privacy and security that Zcash offers—happy transacting!
