I’m not an expert on this either. I’d defer to nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg on whether this is currently feasible.

I know that I can send sats via lightning to you at [npub]@npub.cash. You do a nostr login and claim the sats (as ecash on the npub.cash mint). Only you can claim these sats. This is one example of pay-to-pub key (P2PK) ecash. In fact, there are 300 sats for you there now. Check it out.

Say you’re using a nostr client on the web. Here’s a possible flow (that would need some work to build):

- have a browser extension to log the npubs of the accounts you want to tip

- those npubs are saved in a database

- your website has a default landing page with info about the company/product

- there’s a button to claim ecash

- a user hits the button and inputs their npub

- if the npub was in your database, your wallet sends x number of sats P2PK
