The .xp extension is owned by Jordan, who you can find on X as @eskimo_dev, he has an open source EPP server with HNS in mind.
Also, take a look at hns.id/ which are another HNS implementation, and is another Namecheap initiative to stack HNS names.
You will only need to check this for Porkbun and Namecheap, which are the main traditional registrars that have added HNS. Ideally, these would be marked in the API, just as they are marked as experimental in the frontend.
Oh rad! I'll get this sorted. I like the idea of being able to add HNS names 👍 I'll just need to mark them as such. Porkbun's API (and I suspect every other api) doesn't mark them as HNS TLDs. So I'll need to figure out a different way to determine if
It's not the only Handshake name I have here; I dare you to find the other one 😅. By the way, these are disabled from receiving offers to avoid causing a mess.
I was keeping this to share in a full feedback, but you noticed. The short story is, this domain is derived from a TLD over the Handshake Protocol (HNS), it was available for registration via Porkbun, and I was actually able to verify it using the import method.
Actually, it exists but in WEB3 naming space, so I suppose he registered this domain name within some registrar and was able to verify it here through import?
