I sent some sats your way a few days ago.
Correct me if I'm stupid or just plain blind though, but this geyser.fund link doesn't seem to be in any prominent place in the Github README or the blixtwallet.github.io page or the app. I was actually looking for a way for a while to contribute to the app but wasn't able to find it before.
Since you seem to have GitHub sponsorship setup, maybe you should also add this link (or some LN address) to the README?
