It is not possible to add a fee to API transactions - the number field is just greyed out. Add the functionality to allow this. For example on LP swaps, the ether fee is disjointed and I want to be able to soft delete the ether fee and add it instead to the trade so it is included in my cost basis.
This is something I need too, there is a mismatch on my XLM trades where I moved the coins from my ledger to binance.
I’m not sure if this is the same but I see with BSC that it treats the BNB transaction fee as a separate cost, rather than incorporating it as a fee within the transaction. I’d also prefer it appeared as a fee in the same transaction, rather than lots of separate “Cost” transactions.
Interesting. I have 1 remaining XLM displayed in Koinly that I don’t hold anywhere - likely because of this.
I would like to do the same. I have a lot of cost transactions that should have been fees on a trade or transfer.
