Big issue. Please help me

I had transferred funds to my Sphere wallet and was running a node on Allnodes. Today, when I tried to withdraw funds, I noticed that a withdrawal seems to have occurred in July. However, I did not make this withdrawal. The withdrawal address is zncArhenGaa75V4hAf1ShiGvhcRQqdPELU2. What issue might have occurred? Please help me.

I think perhaps you moved around funds in that address at some point and you just dont understand the functionality of the Bitcoin and Horizen and other address tree structures.

whenever you move something from one address it will look like another amount is moved out of your control, but its should more than likely still be in your same account you are holding under if I am understanding correctly perhaps. if not it would be pointing to possibly you private details were compromised in some way?

Yeah hopefully your system wasn’t compromised. Was the zncArhenGaa75V4hAf1ShiGvhcRQqdPELU2 address yours or the address into which your funds went? It seems that one dumps into what looks like an exchange address:

Have you tried interacting with the team on Discord? At least someone should be able to walk through the incident with you to see if there’s any way to figure out what happened.
