Frequently Asked Questions

Yes. The domain is stored in your cryptocurrency wallet. After you mint your domain on the blockchain, you can transfer it anywhere you like.

We currently support over 310 cryptocurrency addresses to map to a domain name to make payments easier.

You will need to use a mirroring service, a browser extension or a browser that supports onchain domains.

Major search engines don't currently index onchain domain websites since the content is hosted on p2p networks such as IPFS.

No. Onchain domains are what’s called alternate roots. They are not part of the current DNS. We will be collaborating with our partners to plan and strategize for applying to the upcoming Internet Corporation for Assigned Names and Numbers (ICANN) general Top Level Domains (gTLD) application round in 2026. The goal is to create Web2-Web3 domain "twins," allowing users, brands, and companies to take the best from both worlds and fully leverage the power of onchain domains within the traditional Internet space.

No, not by default. Sharing ‘whois’ information is opt-in, i.e. something that you can choose to do. Otherwise, your identity will not be publicly known.

Trademark holders with proof of ownership can apply on to claim ownership of trademarked names. Unstoppable Domains does not have the ability to take back trademark domains that were already purchased & minted.

When someone types yourname.u into any of the wallets that support our branded domain extensions, the wallet looks up that domain on the blockchain, finds the appropriate address, and sends the crypto to the address associated with that name. You can add your Bitcoin, Ethereum, and Solana addresses to your onchain domain inside of the ‘My Domains’ section at unstoppabledomains.com.
