Is it possible to connect Electrum wallet to my own Lightning Node?
If you want to manage your node using Electrum then it is not possible. Lightning Network support in Electrum is a standalone implementation written in Python.
Spark Wallet can connect to a c-lightning node and provide basic functionality (channel management, sending and receiving payments). It is available for Windows, Linux, Mac and Android.
If you want to open a channel with your node then you need your node's id and IP address. Keep in mind that all of your payments will fail if you don't have any open channels with other people on your c-lightning node.
Hum, ok.
The thing is that I installed a small game that pays a couple of sats via LN but it needs some LN wallet. And as I have Electrum already installed, I was trying to avoid to install more stuff.
So, I guess I don't have another way but install some 3rd party wallet, I guess. I doubt I can connect the game directly to my LN node and be able to receive the sats directly to my node in some way.
