# ENS The Ethereum Name Service (ENS) is a decentralized naming system built on the Ethereum blockchain, allowing users to register and manage human-readable domain names (like `yourname.eth`) that can be linked to Ethereum addresses, smart contracts, and other decentralized resources. ENS simplifies the process of interacting with blockchain addresses and resources by replacing complex alphanumeric strings with easy-to-remember names, enhancing the user experience in the Ethereum ecosystem. ## Key Features * Current primary name * ENS holdings (All the ENS names holds by an Address) * Resolved ENS names (All the ENS names resolved to the Address) * First registration time * First primary name set time --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
