The ETH Address is the wallet your ENS name points at. ETH sent to yourname.eth lands in the wallet listed here. It's one half of how a name resolves: the ETH Address on the name says which wallet the name belongs to, and the Primary Name on the wallet says which name to display. Apps need both to line up.
When you register through the ENS App, the ETH Address is set to the wallet you registered with — you don't need to do anything for the default case.
Good to know
The ETH Address is where ETH sent to
yourname.etharrives.Once you change it, funds sent to
yourname.ethgo to the new wallet, and the old wallet stops receiving them.Without an ETH Address set, the name can't be used as a Default or Mainnet Primary Name.
The same name can hold separate address records for other chains too — see How do I add wallet addresses for other chains?.
The ENS App only handles
.ethnames and onchain subnames. For project subnames likebase.ethoruni.eth, use the project's own site.
When you'd change the ETH Address
Change it when you want a different wallet to receive ETH sent to yourname.eth, or when you're trying to set a Primary Name from a wallet that the name doesn't currently point at. The two common cases:
Receive payments at a different wallet. Common when you've moved funds to a new wallet and want to redirect.
Set a Primary Name from a different wallet. A Primary Name only sticks if the name's ETH Address points at the wallet you're setting it from. If your name doesn't appear in the Primary Name drop-down at primary.ens.domains, the ETH Address probably isn't set to the wallet you're connected with — either switch wallets, or change the ETH Address.
How to set or change the ETH Address
Connect with the Manager — the wallet that controls a name's records — and have a bit of ETH on Ethereum Mainnet for gas. No other cost.
Open Edit Profile. Go to app.ens.domains and connect your wallet. Search for your name, open the Profile tab, and click Edit Profile.
Set or update the ETH Address field.
Approve in your wallet. Most confirm in 1–2 blocks (12–24 seconds); busy networks can take longer.
Once it lands, funds sent to yourname.eth go to the new wallet.
