Owner of an NFT on zkSync Era: the wallet that holds one ERC-721 token id right now (ownerOf), plus the collection's name and symbol. Use to verify who holds an NFT before a trade, a mint gate or an airdrop; for how many a wallet holds use zksync_nft_balance, for the token's metadata zksync_nft_metadata. A missing contract or a token that does not exist is 422, uncharged.
