The Ethereum Name Service (ENS) provides a human-readable naming system for blockchain addresses, replacing long hexadecimal addresses with memorable names like vitalik.eth. Our ENS lookup tool lets you resolve ENS names to Ethereum addresses and perform reverse lookups from addresses to their registered ENS names. This works bidirectionally, making it easy to find an address for a known ENS name or verify what ENS name is associated with a particular wallet.
ENS names have become a standard identity system across the Ethereum ecosystem and beyond. They are used for receiving cryptocurrency payments, domain ownership verification, NFT metadata, Web3 username registration, and decentralized identity systems. Rather than copying and pasting lengthy 0x addresses that are prone to errors, you can simply share your ENS name. Our lookup tool helps you verify ENS records, resolve addresses for sending transactions, and explore the ownership details of registered names.
ENS resolution works through the Ethereum blockchain's ENS registry and resolver contracts. When you enter an ENS name, our tool queries the ENS contract to retrieve the associated Ethereum address. For reverse lookups, it checks if the address has configured a primary ENS name. This decentralized resolution happens entirely on-chain, meaning there is no central authority that can modify or censor ENS records. Our tool connects directly to Ethereum RPC endpoints to perform these lookups in real-time.
