The platform provides users with a domain name matching their Twitter handle, requiring only for authorization using Twitter credentials via its app.
However, utilizing this name requires owning a cryptocurrency wallet and visitors to your website will need to use a specialized plug-in or browser in order to address it. Unstoppable typically sells .nft names for $29 with no renewal fees and currently holds over 3.1 million names across its collection of crypto-themed alt-root TLDs.
