Farcaster Usernames
A Farcaster account needs a username so it can be found and mentioned by other users. Farcaster uses the Ethereum Name Service to manage usernames.
ENS usernames are owned by Ethereum addresses, just like Farcaster accounts. The difference is that an address can own multiple ENS names, so the Farcaster account must specify the name it wishes to use. Names must be less than 17 characters with only lowercase alphabets, numbers or hyphens to prevent homoglyph attacks.
Two kinds of ENS names are supported:
Offchain ENS Names: free and controlled by farcaster. (e.g. @alice)
Onchain ENS Names: costs money and controlled by your wallet. (e.g. @alice.eth)
Prerequisite to using your ENS name:
ENS Name has an ETH Address Record
For an ENS name to work as a receiving address it must have an ETH Address record. To update this, follow the guide How to Edit Roles
Farcaster Verified Address is the same as the ETH Address Record
Farcaster supports proof of ownership of an Ethereum account to your profile. You can use any .eth name that resolves to a connected address on your farcaster account. This means that ETH address record and your Farcaster connected address will be the same.
