Exercise: you got to send someone money, but the payee didn't publish a bitcoin or LN address you trust. The onchain fees are high anyway for the price of a dinner.
Nostr solves this often, but let's say you just got some other social media contacts.
Solutions:
1. LNURLw
generate an LNURLwithdraw voucher and share the link or QRcode so the recepient can withdraw with most lightning wallets any time. This needs a LNURL server. Some ways to it:
- run BTCPayServer - create a Pull Payment, share the link or QRcode
- run LNbits - create a voucher with the LNURLw extension

Does anyone has any other practical solution working now for async payments?
I'd like to pay bitcoiners more often, but sometimes not when I can just ask for a lightning invoice.
