# Ownership of Assets Any content created in the virtual world is owned by creators. Relevant data is stored in hash value in the non-fungible token standard ERC721 and ERC1155. NFT tokens represent item ownership and can be freely sold or leased to delegate ownership rights to another person or business. In the future, NetVRk will allow creators to mint NFTs using a wide array of blockchains including Ethereum, Polygon, Avalanche, Solana, Cardano, Polkadot, XRPL, Flare, Hadera, and others as guided by community requests. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
