Please note, Hodlnaut halted withdrawals, token swaps and deposits on the 5th of August 2022. You can still do your Hodlnaut taxes with Koinly.
The first step is to download all your transactions from Hodlnaut and import them to Koinly. There are a couple of ways you can do that:
If you do use CSV files, you have to make sure to import your deposits/withdrawals and trades for ALL previous years - not just the current one!
That's all you have to do. The only other thing to be vary of is to tag your airdrops/forks so they show up as Income on your final crypto tax documents!
