It can be a bit overwhelming it's true! The future does have new features and terms, just take it slow.

Zaps is the term for micropayments you can receive from and send to other users as little tips. Relays are simply the servers where your content ie notes, are stored.

The simplest way right now to set up Zaps is to log in to Primal iOS or Primal Android and create a wallet. It's pretty intuitive.

Relays you don't need to worry much as most apps have them set for you, but you do have the option to pick them yourself. A lot of the apps have relays recommendations in the relay settings for you to pick if want/ would need to.

Which app are you using?
