When a user claims kk, GetZap fills every slot that Nostr apps already know how to read.

Slot	Value
Lightning	`kk@getzap.me` → `/.well-known/lnurlp/kk`
Bitcoin deposit	unique `bc1…` → credited as Lightning sats after 2 confirmations
Verified name	`kk@getzap.me` → `/.well-known/nostr.json?name=kk`
Inbox	kind 10050 → `wss://relay.nostrfeed.com`
Wallet apps	NWC on the same relay
Ecash	`https://mint.nostrfeed.com`
Pictures	Blossom on this host, NIP-05 users only
Login	NIP-46 bunker, not email

On the Nostr profile, set both fields to the same string:

{
  "nip05": "kk@getzap.me",
  "lud16": "kk@getzap.me"
}

The connect page prints the unsigned events. NostrFeed (or any signer) publishes them.
