What is NFT spoofing (impersonation)?
Anyone who wants to issue an NFT can do so. And because NFTs leave the issuer's hands and can be traded on marketplaces, if the contract underlying an NFT (even an ERC721 non-fungible token) and its associated tokens are copied exactly as they are, it becomes very difficult to tell them apart by anything other than their addresses. In particular, from the images on a marketplace alone, it is hard to tell at a glance which one is genuine.
Normally, you might sense that an item is fake if its price is low compared with past transaction prices on the marketplace. But if there is a history of deals deliberately closed at high prices, it is difficult to tell at a glance whether it is fake. It helps if the issuer has clearly stated the contract and token addresses of their NFTs, but addresses are hard to remember and at a glance look like just a string of characters, so they are hard to use for identification on their own.
HEXA's protection against spoofing (impersonation)
To prevent impersonation, HEXA verifies the issuer's account to confirm who owns the social media post. In addition, the metadata on the blockchain includes a HEXA NFT-specific ID for preventing impersonation, along with the URL and QR code of the HEXA NFT page on which the issuer has been verified. So even if an impersonation NFT appears on a marketplace or elsewhere, when you try to view the contents of that NFT, the HEXA NFT page verified by the issuer appears, showing the genuine NFT's token address, contract address and links to marketplaces, so you can identify the genuine NFT. Issuers can also remove this anti-impersonation HEXA NFT card mask. Therefore, not every NFT has the anti-impersonation card mask applied; it is up to the issuer.
