I'm trying to find the blurt blockchain, but no results till now. Is there a Zapata also? This is really new!!
I think hive.blog also allows to change your keys. I'll contact on Discord on the process you asked me from SW, ;)
Best wishes dear friend, even with these days passing fast I'm always happy to visit your blog and your great writing style!!
I will help you with your questions on a DM my friend! 👋
