Wallet of Satoshi uses LN addresses which look like email addresses but work differently. If you want to send your friend some sats, have them create an account with WoS or GetAlby and send you their LN address.

This is how kraken and coinbase grow, like paypal did.

Wallet of Satoshi requires a real lightning address afaik.

Have your friend setup a wallet on coinos.io or walletofsatoshi.

Anyone tried this plugin that transform email addresses into Lightning Addresses? https://github.com/Walletano/Walletano-Email-to-Lightning

You can create a redeemable tip using this website: https://lightsats.com/dashboard

They can then choose their own wallet to handle the redemption, no need to create an account.
