ERC721Multiwrap

BASE: ERC721Base EXTENSION: TokenStore, SoulboundERC721A The ERC721Multiwrap contract uses the ERC721Base contract, along with the TokenStore and SoulboundERC721A extension. The ERC721Multiwrap contract lets you wrap arbitrary ERC20, ERC721 and ERC1155 tokens you own into a single wrapped token / NFT. The SoulboundERC721A extension lets you make your NFTs 'soulbound' i.e. non-transferrable.
