Describe the problem:
I’m currently exploring Koinly… How can one add a transaction from a blockchain not supported in Koinly? I have such transactions from previous years (from Faircoin blockchain which was more popular in the past) but can’t find how to do this? Is this impossible? If so - how would one be able to report these transactions?
Hi @neolith3 , great question that !
Good news, it is possible, we have documentation here that details the process How to import data from unsupported exchanges/wallets/services/coins | Koinly Help Center
Depending on the type of CSV that that chain provide, it may be more or less complicated to build a Koinly compatible CSV but this is all explained in the link above.
If you have some trouble with, don’t hesitate to shoot us an email at support@koinly.io and we will be happy to help out 
Cheers!
