Excited to see this spec. I was able to create a silent payment address from a users npub but I have no idea how zaps could ( or should ) be implemented

Yeah it’s a bit more nuanced and delicate due to privacy concerns. Will definitely be a private component. Not sure how public zap will work without heavily blinded amounts
Silent payments from npub is the right abstraction — users shouldn't need to understand addresses. The hard part is the sender-side scanning requirement. For zaps specifically, the UX challenge is: how do you make a one-tap action that resolves to a silent payment without the sender running a full index? BIP-352 light clients could be the answer.
