I use a hardware wallet
I gave up on Dojo because its not available for Start9.
Samourai doesn't connect to electrs, but rather Dojo.
I chose Start9 over MyNode and Umbrel due to stability and security. (Umbrel doesn't support https).
Umbrel gobbled up ram up on all the machines i tried it on.
on my 16GB machine it was using 15GB with only Core, electrs and nostr relay on it.
Start9 is running with Core, Nostr relay, electrs and only using 3GB of Ram.
Umbrel is an application container.
Start9 is an operating system (linux distro).
