So there are many bugs with zaps in the build, they will probably only work on my posts for now. You can change the default zap amount in settings, its 1000 sats by default. I still need to add a screen for changing the zap amount per post and adding comments. Will work on this soon!

If you want zap support on your lightning wallet, please bug your lnaddress provider to check out the NIP-57 zaps proposal!
