Ethereum Name Service is a protocol that enables users to register human readable domain names for their crypto addresses, making sending and receiving TXs more user friendly. ENS is multi-chain, with .eth working across 100s of coin types, including BTC, SOL, EVM L2s, + more.

While .eth is the most recognizable part of ENS, the protocol is so much more. Users can register .eth names at http://ens.app or on many secondary marketplaces. These domain names are specifically registered on the Ethereum blockchain using the .eth top-level domain.
