Since ABRA is an all-in-one Wallet/Exchange, it is possible to import your transactions via Wallet Address import. Below we provide instructions on how to do this.
Step-by-Step Instructions to Import ABRA via Wallet Address:
Step 2: Click the ⍈ Add Money icon in the bottom toolbar. Choose Deposit Cryptocurrency.
Step 3: Select the relevant coin/blockchain.
Step 4: The long alphanumeric string (27-34 characters) below the QR code is your coin's public address
Step 5: We will need all of the Abra history; 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.
