Will ERC-1155 NFTs appear in my wallet? Many NFTs use the ERC-1155 token standard, including those created through the OpenSea Collection Manager. Etherscan doesn't currently support the ERC-1155 standard, so it won’t show those NFTs. MetaMask supports holding ERC-1155 NFTs, but you can't see them natively in the MetaMask Mobile app. Related articles How do I create an NFT? How do I create an OpenSea account? How do I sell an NFT?
