ENSv2 is a rebuilt Ethereum Name Service protocol now live on mainnet. It adds hierarchical registries so a name can act as its own registry, more precise permissions for sharing namespace control, a new ENS App for everyday registration and management, and an ENS Explorer for inspecting name history and configuration. Existing names continue to work and eligible .eth names can be upgraded.
ENSv2 is a generation of the Ethereum Name Service protocol, accompanied by the ENS App and ENS Explorer. Its hierarchical registry architecture lets names have registries for managing subnames, while role-based permissions provide more granular control. The App supports everyday name registration and management, and the Explorer lets users inspect names, records, roles and history. Existing ENS names continue to work, and eligible .eth names can be upgraded. ENSv2 also supports linking records so names can share resolver data.
The ENSv2 contracts audit materials list OpenZeppelin Contracts among external dependencies, including ERC-1155, ERC-165, UUPS and access-control components.
