Can people see if I own multiple Yats?

Yat and Yats are designed from the ground up to be as privacy-respecting as possible.

We do not link Yat Creators with their Yats by default, and the only way that anyone besides the Yat Creator would know that a Yat is owned by someone is if the Yat Creator chooses to disclose the other Yats that they own.

With that said, should a Yat Creator choose to mint all of their Yats into the same ETH wallet then their entire collection of minted NFT Yats would become public -- just like any other NFT that they own in that wallet.
