I'm assuming it isn't a wallet, but it is just an URL shortener. If I get the chsance, I'll do a bit more research. I'm a bit cautious about preregistering domain names for new TLDs. In the past, some of the registries have taken the fee, and then put the name up for auction, or sold to a higher offer. $10 seemed worth the risk though, as it could be a useful service.
It is a URL shortner. But the domain is only registered in Zilliqa’s blockchain. If you type the domain in your regular browser, it won’t see it as valid.
If you type the URL in a wallet that doesn’t support it, it won’t do anything either. You need a wallet that has their code implemented so it knows that this is a Zilliqa’s unstoppable domain and that it should look for it at their blockchain for the address and/or the IP of the website server.
So it needs a supported browser and wallet for it to work.
From their FAQ:
Does Unstoppable Domains provide you with a wallet?
Yes, but only for holding your blockchain domains. In order to send and receive cryptocurrency using your domain, you will use wallets that have integrated our software
How will I be able to view a .zil website?
You will need to use a browser extension initially. We are working to integrate browsers natively
