Farcaster username checker for fnames

Farcaster is a decentralised social network popular in crypto, and every account gets a free username called an fname. This Farcaster username checker looks the name up in Farcaster's official registry.

fnames are 1 to 16 characters using lowercase letters, numbers and hyphens, and can't start with a hyphen. You can also use an ENS .eth name, which is registered separately.

Crypto communities span Farcaster, X, Discord and Telegram, and impersonators follow popular names. Check all of them, plus the .xyz and .com, in one search.

Tips for a Farcaster name

  • Up to 16 characters: keep it short.
  • Match your X and Discord handles.
  • Hyphens are allowed, underscores aren't.
  • Grab the matching .xyz or .com.
  • Pick one you'll keep: changes are limited.
