I have all my XRP on Ledger nano for 2 years now. I jumped through the hoops to setup Ledger Nano for the Spark token air drop. I just now started looking for a way to cancel, delete before snap shot if I need to. Running out of time like sand in an hour glass!
I have not found a way yet. Maybe I could delete the Etherium Wallet from my Ledger. Not sure if that would do it or not. I did have to create the Ether wallet in order to setup to receive the spark.
I have looked at the Ledger and I see my spark address and the other long code with the 2 and all the zeros on the public XRP ledger. So who the hell knows?
We are in a new world now guys and gals!!
Don't ask me how I setup Ledger to get the Spark, as I watched Youtube videos, and paused, play, pause until I figured it out.
Good luck to all!!!!
