FUN FACT: very few nostr users know that Zeus have an integrated NWC server that can be used with zaps on nostr and receive instantly over the zeuspay LN address with cashu.
The new LDK embedded node is very fast and reliable. For using on nostr you only need a simple LSP channel or a even a regular with any other reliable peer and you are ready to go on nostr zapping.
You don't even have to keep Zeus open, just use persistent mode and works in background, always online and ready for NWC sub-accounts.
Stop using all other bullshit fake non-LN solutions. You are being LIED!
