Frequently asked questions

What is an ENS (.eth) name?
ENS (Ethereum Name Service) names like yourbrand.eth are web3 domains: human-readable names that map to crypto wallet addresses and decentralized websites, stored on the Ethereum blockchain as NFTs.
How is .eth availability checked?
We query the ENS BaseRegistrar smart contract directly on the Ethereum blockchain to ask whether the name is available — an authoritative, on-chain answer. No wallet or sign-in is needed to check.
Why do .eth names need to be at least 3 characters?
The ENS registrar only allows registration of names with three or more characters. Shorter names aren't registrable through the standard controller, so the checker requires at least three characters.
