Look up a name or address
ENS is a readable nickname for a wallet address — like a domain name for a website. Type either one; we work out which.
e.g. vitalik.eth or 0x1234…abcd

Enter a .eth name or a wallet address on the left — the match appears here.
Name service availability
ENS resolution is an Ethereum mainnet protocol, so there is no chain picker here — every lookup on this page runs against Ethereum (https://eth.llamarpc.com). A name registered on another chain's registry will not resolve here.
Base and Base Sepolia use Basenames, an ENS-compatible registry with its own L2 resolver. Resolving those names needs the Basenames resolver address, which is not bundled in this app's chain registry — so rather than ship a half-working resolver, this tool stays Ethereum-only. Look Basenames up on the Base explorer or the Basenames app instead.
