ENS App and Explorer are on the Sepolia testnet. Features may change before mainnet.
What is an ENS profile?
Your ENS profile is everything attached to your name beyond the name itself: a bio, avatar, contact details, social handles, wallet addresses on other chains, plus a few technical fields. The profile lives on the name, not on you as a wallet, so if you transfer the name, the profile goes with it.
In the ENS App, your profile shows at app.ens.dev/<yourname>.eth, and anyone with the link can read it. You edit the same records at app.ens.dev/p/<yourname>.eth/edit.
What are records?
A record is a single piece of data attached to your name. Each record has a type and a value: an Email record holds an email address; an X record holds a handle; an Ethereum address record holds a 42-character address. Records are stored on a contract on the Ethereum network called the resolver, and wallets and apps read them when they want to know what your name means.
Records are what make a name useful: a wallet sending tokens to yourname.eth reads your Ethereum address record, and a profile page reads your Bio record.
What records can I set?
Quite a few. The ENS App's Edit Profile page groups them into panels:
Bio: Short Description, Website.
Contact Information: Email Address, Location, Phone Number, Mailing Address, Timezone.
Social Links: X (Twitter), Telegram, Farcaster, Instagram, Discord, GitHub, LinkedIn, YouTube, Reddit, TikTok, Twitch, Mastodon (12 platforms).
Wallet Addresses: Ethereum (the default), plus 100+ other chains (Bitcoin, Solana, Polygon, Optimism, Arbitrum, Base, and others).
Avatar and Theme: an image, plus a colour for the badge that shows your name.
Links: free-form Name + URL pairs for anything that isn't in the social list.
Other: Content Hash (points your name at a website on a decentralised network such as IPFS) and ABI (technical data, only for names that belong to a contract).
You don't have to set any of them. Pick what you want; leave the rest empty.
Where do records appear?
Wherever an app or wallet looks for them:
On your public ENS profile in the ENS App, at
app.ens.dev/<yourname>.eth.In ENS Explorer, on the Records tab of the name's page.
In any wallet or app that supports ENS: sending screens reading your address record, profile cards reading your avatar, identity widgets reading your socials.
Who can see them?
Anyone. Every record you save is publicly readable, with no permission gate. If you want a private contact method (somewhere the ENS App can reach you about expiry, transfers, and updates without showing the address publicly), use the Email and Telegram fields in notification settings instead; those are private to your wallet.
