A project subname is a subname issued by a project — like yourname.base.eth or yourname.uni.eth. The project runs its own registration system, so you get one and manage it on the project's own site, not in the ENS App. One exception: you can set it as your Primary Name in the ENS App.
Good to know
Issued by the project. Examples:
base.eth,uni.eth,linea.eth,celo.eth,gemini.eth. Each runs its own registration system.Managed on the project's site. Registration, renewal, record edits — all happen on the project, not in the ENS App.
Primary Name still works in the ENS App. You can set a project subname as your Primary Name in the ENS App or at primary.ens.domains.
Support comes from the project. ENS support can't manage or recover a project-issued subname — contact the project directly.
Where do I register and renew?
On the project's own site. Each project runs its own registration and renewal system, with its own pricing and rules. Check the project's site for current details.
Can I manage my project subname in the ENS App?
Mostly no. Records like wallet addresses, avatars, and social handles are set through the project's interface, not the ENS App. The exact mix of what's editable where depends on the project — but for changes, use the project's site.
Can I set it as my Primary Name?
Yes. The Primary Name is set onchain through the ENS App (or at primary.ens.domains), and it works the same way for project subnames as for .eth names. Once set, ENS-aware apps will show your project subname wherever they'd otherwise show your 0x address.
Where do I get support?
From the project. ENS support can't issue, transfer, or recover a project subname — the project owns the registration system. Most projects publish help docs on their site; start there.
How project subnames work
Each project owns a .eth name (base.eth, uni.eth, and so on) and uses it to issue subnames to users. The project controls the issuing system, so it sets the rules — who can claim, what records are editable, how renewal works. The subnames are real ENS names; they just live under the project's parent, not under one you own.
Want full control through the ENS App?
Register your own .eth name. With a .eth name you can set wallet addresses across chains, create your own subnames, edit your profile, and manage everything in the ENS App.
