The smallest unit of bitcoin. It is short for satoshis. There are 100 million satoshis making up a whole bitcoin. There are only ever going to be enough satoshis for the average person on earth to have around 270k sats, which today can be obtained for about $60. If you connect a Lightning wallet (LNURL) to your Nostr profile, people can use the Lightning network to instantly and cheaply send you sats.

This was so helpful. I didn't see a field under edit profile here to connect a wallet?
Also, for android, what lightening wallet do you recommend? Seems my wallets don't support lightening altho I downloaded more today, so maybe I'm getting closer to figuring this puzzle out. I guess the sats is why I couldn't send a tiny increment of BC today thru the cash app bc wallet #[8] ?
