I had trouble doing Cardano transaction tax in the past, so made something to make the process much easier and more enjoyable. I decided to publish it as it might be useful to others too… looking for anyone willing to try it out and feedback, bug test etc. Here is the link https://txnerd.io
You can import all of your wallet transactions, track trades, native tokens, NFTs, staking rewards and export CSV files for use in crypto tax software, or just to use the CSV file itself. Also good for checking wallet balances on specific days in the past. Let me know if this sounds useful to you, thanks!
