Ethereum Name Service has launched ENSv2 on the Ethereum mainnet, introducing a rebuilt naming architecture aimed at giving users more control over how blockchain names are administered. The update changes how names can be organized and delegated, while keeping existing ENS names active without requiring holders to register again.
The new version adds a hierarchical registry and more granular permissions. Under that design, a single ENS name can operate as its own on-chain naming system, and management authority for individual subdomains can be assigned separately rather than handled through a single, broad set of controls.
A broader redesign for ENS names
ENS described ENSv2 as its next-generation naming protocol. The system is intended for individuals, communities and companies that need more precise administration of on-chain names and subdomains.
The hierarchical registry is a central part of that redesign. It allows one name to serve as a parent namespace, with separate rights assigned for specific parts beneath it. That structure is meant to make name management more flexible for users who want to organize multiple identities or services under one ENS name.
App and explorer updated alongside the protocol
The mainnet rollout also includes changes to ENS’s user-facing tools. ENS said it rebuilt both the ENS app and ENS Explorer as part of the release.
According to the project, the app now streamlines name registration and renewal, profile settings and notifications. ENS Explorer has been expanded so users can inspect a name’s change history, controller, connection method and current settings.
Existing names remain active, with upgrades optional
Current ENS names will continue functioning without re-registration, a key point for existing users as the new system goes live. Access to ENSv2-specific capabilities, however, requires an upgrade for existing .eth names through the ENS app.
That approach means legacy names stay usable while name holders choose whether to move into the new framework. ENS presented the upgrade path as a way to unlock the additional management and delegation features introduced in ENSv2.
Scale, potential uses and launch incentive
ENS said it currently supports more than 36 million names across .eth and other namespaces, and that more than 600 applications already support ENS name resolution. The project said ENSv2 could be used to identify a wider set of on-chain entities, including tokenized assets, companies, organizations and AI agents.
As one example, ENS said a tokenized asset issuer could connect contract addresses across multiple networks and related documents under a single namespace. To mark the mainnet launch, the project also introduced a commemorative ENSv2 NFT collection. Eligible users can receive one NFT per wallet after upgrading a name to ENSv2.
