Phoenix can enable dynamic channel size thanks to their splicing feature developed by ACINQ on LNKMP. Zeus embedded node uses LND as backend & splicing is yet to be developed by LightningLabs. You can open channel to any public nodes. You can also receive LNURL-channel too

I'm not sure Zeus can automatically swap onchain sats to LN sats, you can swap the sats to LN using submarine swap lik boltz tho. Note that you can store sats onchain using Zeus SEPARATELY unlike on Phoenix, 2 layers 1 app

 No swaps yet. 

 Out of topic but... will i lose my nsec stored (on my Zeus mobile) if i reinstall the app ? 

 Yes, copy it from Nostr keys section first. Hold to copy 

 What are the specific purpose of built-in nostr nsec there ? To receive nostr notif push whenever users receive pending payment to their LN address ? Anything else?

 Ahhh thanks man! 

 You’ll also trigger a force close of your channels on reinstall so consider manually closing your chans first to save on fees and fund recovery time
