Here's what you need to do
The first and usually the only step is to download all your transactions from delta and upload it into Koinly. There are a couple of ways you can do that:
- Delta does not have any API, so you will need to download your transaction history from their web interface and import it into Koinly manually. You don't need to make any modifications to the file. Koinly will automatically map the columns to ensure all data is imported correctly.
- If you only have a few transactions and the above method(s) are not possible for you, you can also add the transactions one by one via Koinly's web interface.
If you want to import CSV files, you need to make sure to import your deposits/withdrawals and trades for ALL previous years - not just the current one!
That's it. Don't forget to tag your airdrops/forks so they appear as Income on your final cryptocurrency tax documents!
