Does .web3 exist?

No. No — .web3 is not a real TLD. 'Web3 domains' live on blockchains, not in the ICANN root.

The full story

Names like yourname.web3, .eth or .crypto are sold by blockchain naming services (ENS, Unstoppable Domains, Handshake) and resolve only through wallets, browser extensions or opt-in gateways — not the global DNS. No browser reaches them by default, and ICANN has never delegated .web3. They can be genuinely useful inside crypto, but they are not interchangeable with a domain you can point a normal website at. For that, use a real TLD.

What to use instead

.io — The default startup TLD of the 2010s.com — Still the king.app — The obvious home for an app

Wondering about another extension? Every real TLD is in the directory.
