Zaps are a new note type that represents paid lightning invoice receipts sent by a lightning node called the zapper. They allow users of the Nostr social media platform to tip one another, pay for goods and services, unlock content, and even deter spam.
To set up zaps on your Nostr profile, you will need a lightning network-compatible wallet and a Nostr client that supports zaps. Once you have a lightning address, you can paste it into the address on your Nostr profile to enable zaps.
To zap someone, select the zap icon and choose a preset or custom amount, add a comment if desired, and select whether you want your zap to be public or anonymous.
