Unfortunately I sort of lost contact with everyone on Hive, because I've been suffering from a brain condition, but I'm really curious to know how have you been doing and what you've been up to for the last two years.
Anyways, in order to sell or transfer your punk you will need to have the Hive Keychain extension installed to your browser, then you just go to https://punks.usehive.com/gallery/boscohage to make transactions.
I hope this helps, but if you have any problems, you can also reach me in the Punk Legends - Discord channel:

I just saw this, I'm sorry to hear that man. I hope things are doing better.
