At the moment, all accounts are private. The only way someone could figure out you controlled a wallet for a specific NFT is if you had a Wave or Photon set to the “Bar” display mode. From there, a person could follow the QR code to the provenance page (which proves ownership) to see the wallet address connected to that NFT. Technically, given the name of the NFT, a user could figure that out on OpenSea.
In the future, we will provide users with a public profile. We will also allow users to opt-in on which addresses are public and which are not. This will ensure any private addresses are not doxxed or associated with you.
