Except for wallet of satoshi, i was unable to get a LN Address from other wallets. My own lightning node (umbrel) has a similar address with @ in the middle, but that does not work with nostr. Maybe because my umbrel goes via TOR network.

Hopefully umbrel lightning node will be upgraded soon to support zaps. Because I am not s fan of using centralized custodial solutions. Not even for such small purposes as zaps. Because eventually all such small things are little seeds that ALWAYS grow into full fiat usurping everything.
USD was also once pegged to gold, until one day gold got confiscated, another day after decades it was devalued against gold, and another day after another decades it got unpegged, and after another number of decades here we are - full fiat and WW3.
