Thanks for your simple guide. It helped me a lot to make my Attach wallet. Now I understand well why I need to make the WA to send because as soon as I put an amount in auto withdrawal, what exceeded that amount I received in my Lightning address. The question is, because I use Blink and I made the API key configuration, in this case it is so that every time I go to publish, comment or zap, the necessary SATs are used from that external wallet?
