Since ABRA is an all-in-one Wallet/Exchange, there are 2 options for importing ABRA: 1) exchange CSV or 2) wallet address import.
EXCHANGE CSV INSTRUCTIONS
How can I generate an ABRA CSV for the Exchange?
Use the ☰ icon in the upper left corner to view the menu
Tap Transaction History
Select a report year and enter your email address
Click to accept the disclosure at the bottom of the screen
Then select the large purple Email Reports button

Where in ZenLedger do I upload the ABRA Exchange transaction CSV?
On your desktop or laptop computer (not mobile device), download the CSV file from your email. Save it in a folder that is easy to remember.
In ZenLedger, navigate to Wallets/Import
From the list of Exchanges, scroll down to select ABRA
Click Import CSV
Then, click Browse which will pop-up a window of your computer file folders
Find the ABRA CSV file(s) that you downloaded from email earlier
The upload can be verified on the Transaction Sources page where it will list the successfully imported CSV file names
ABRA WALLET ADDRESS INSTRUCTIONS
Where can I find my ABRA wallet public address?
Click the ⍈ Add Money icon in the bottom toolbar
Choose Add from Crypto Wallet
Select the relevant coin/blockchain
The long alphanumeric string (27-34 characters) below the QR code is your coin's public address
We will need all of the Abra history (why?); repeat this process for each coin/blockchain that you have ever held in Abra.
Note: Ethereum and ERC-20 coins share a single address; no need to upload identical addresses more than once.
