I just zapped you 21 sats from CoinOs lightning wallet 😀🤙⚡ Set up a lightning wallet using an email address and then transfer some sats to it. You can login with a browser extension/nostr key. Primal has a built in wallet, you can also use Wallet of Satoshi. NWC wallets are easier and work better.

I use Alby and connected CoinOs to it so I can easily login to different nostr clients and apps - just copy the wallet string you're good to go 😎👍
