I got no reply so far. I am trying to find out what happened. Sparrow wallet does not allow to set fee higher than 8,192.00 sats/vB which is 600$ now.
https://ibb.co/tpdqmNsI used Sparrow wallet and physically does not allow to set that high fee. Could it potentially be a hack? If so it is odd that the entire change was used as a fee. Very strange case.
