Here's what you should do:
The first step is to download all your transaction data from AirSwap and upload them into Koinly. There are a couple of ways you can do that:
- AirSwap does not offer any API, so you will need to download your transaction files from their web interface and import them to Koinly manually.
- If the above method(s) is not possible for you, you can also add the transactions one by one through Koinly's web interface.
Note that if you want to import CSV files, you have to make sure to import your deposits/withdrawals and trades for ALL previous years !
That's all you have to do. Don't forget to tag your airdrops/forks so they show up as Income on your generated crypto tax reports!
