I've been using Unstoppable Domains for about a year and I recently happened upon a different platform called Freename.io
Unstoppable Domains allows you to purchase Web3 domains that can be used to create a website or a landing page. But they can also be used as wallet address.
In other words, you can connect your favourite crypto wallet to your Unstoppable Domains account and people can just send crypto to you using your domain instead of your crypto address.
Unstoppable Domains allows you to buy .crypto, .nft, .wallet, .x, .bitcoin, .dao, .888, .zil and .blockchain.
Freename is a bit more complex than that.
First of all, you can customise your domain. It can be anything you want, .concept, .autocloud, .publish0x, .yolo. You can even use emoji. For example, I created my LeftFooted.publish0x domain.!
At the moment, Freename relies on Cronos and Polygon to mint domains and it also allows you to purchase TLDs and earn income by licensing with them with a 50% royalty.
I've literally just started using it so I don't know much about it yet. More to come in the next few days.
