How do I set my nickname, avatar, and profile visibility?

Open the wallet menu and choose Profile, then Edit:

• Nickname — shown instead of your address. Nicknames must not impersonate a person, collection, or brand, and Unvault may reclaim misleading or inactive ones.
• Avatar — an image URL or one of your NFTs.
• Visibility — choose whether your profile page is public or visible only to you.

Your on-chain activity is public on the blockchain regardless of the visibility setting; the setting controls only what the Unvault profile page shows.
