Interoperability between different NFT networks is not yet fully guaranteed, as the technology is still relatively new and different networks may implement different standards and protocols. However, there are currently efforts underway to address this issue through the development of cross-chain communication protocols such as Polkadot and Cosmos. These protocols aim to create a framework for interoperability between different blockchain networks, allowing for the seamless transfer of NFTs between them. Additionally, some NFT marketplaces have taken steps to ensure interoperability by supporting multiple blockchain networks and standards, such as OpenSea, which allows for the trading of NFTs on various Ethereum-based networks as well as other networks like Polygon and Solana.
