Hello, if someone wants to open a channel with me, what info does he need from me (node id, pub key?) and where do i get that info in electrum?
You can get your node's id by typing "nodeid()" in the Console. You can enable it in "View -> Show Console". Check out
this reddit post for more instructions.
so, whats wrong with my own testing structure with the 2 electrum wallets ?
Are both of these wallets connected to the same node? Are they open at the same time? Did you spend some of the coins from the second wallet in order to make space for incoming funds?
