What records can I add? Is ENS only for storing an Ethereum address?
You can store the addresses of over 100 blockchains, a content hash of a decentralized website, profile information such as an avatar and Twitter handle, and more.
ENS even allows you to create custom records that can be used by other applications.
What is a Primary ENS name?
A Primary ENS Name (previously Reverse Record) points your Ethereum address to an ENS name. This allows dApps to find and display your ENS name when you connect to them with your Ethereum account. You can only have one primary name per address.
Sending money to an ENS name will resolve to the eth address record, and is not dependent on having a primary name set. However, your primary name must match your Ethereum address record.
To set or change your primary name, visit the settings page in the ENS app.
How do I set up my profile?
ENS profiles are a collection of pre-defined records, which are used by other dApps.
When connected to the ENS app and viewing a name you own, you will see an Edit Profile button on the Profile tab. Here you can update the specific records used for profiles.
What are Managers and Owners?
The Owner is the ultimate owner of the name.
For .eth names the Owner (formerly Registrant) of a name can change the Manager and transfer ownership. Not all names will have an owner.
The Manager (formerly Controller) of a name can change the resolver and add/edit records. Some dApps (eg: Fleek, OpenSea) set themselves as Manager so they can update records on your behalf.
If your .eth name is wrapped, you will not have a Manager as these ownerships are now combined under just a single owner.
If you have PARENT_CANNOT_CONTROL fuse burned as a subname, you will be considered the owner as the parent cannot take over your name.
How do I send my name to another address?
Sending your name to another address will let you transfer the Owner, Manager or both to a new Ethereum address. This can be done from the More tab when viewing a name you own.
Sending the name to another address will not update the records, or make it the primary name for the new address.
What is a Resolver?
A Resolver is a smart contract that holds records. By default, names are set to the Public Resolver, which is developed and maintained by the ENS team and has all the standard ENS record types.
This is recommended for most users, but you can use custom contracts if you'd like.
If you are using an older version of the resolver, you can upgrade it from within the ENS app in the More tab.
What is the Name Wrapper?
Wrapping a name is an upgrade that gives older names access to more modern features, such as burnable permissions and ERC1155 NFT support. All newly registered names are wrapped by default.
If you do have an unwrapped name you will see a prompt to upgrade in the ENS app. This is of course optional, and your name will still work without it.
You can view a full list of features on Github.
How do I find the labelhash/namehash of a name?
Please refer to our developer documentation page.
What is the difference between a name and a subname?
Both are names, however subnames have a parent name. For example with resolver.ens.eth, ens.eth is the name while resolver is the subname.
Subnames usually inherit the permissions of the parent name, however parent name owners can burn their permissions, giving subnames more control.
What are permissions?
Permissions allow the owner of a parent name to remove their access to certain features on subnames.
For example, by default only the parent name owner can transfer ownership of a subname. With permissions, the parent name owner can remove their ability to do so, allowing trustless subnames.
Before burning any permissions, the name must first burn the ability to unwrap and the wrapper expiry must not be expired.
