# NFT Cross-Chain

With the rise of Ethereum L2 solutions, the EVM ecosystem has seen explosive growth. However, the lack of a mature NFT cross-chain solution significantly limits NFT use cases. Imagine if NFTs could freely circulate across chains, not confined to a single chain—this would greatly expand their applications.

Flip is addressing this issue using **ZetaChain** as the foundation for its solution. ZetaChain is a cross-chain messaging protocol built on EVM. It currently supports cross-chain messaging between EVM chains like Ethereum, BSC, Base, and Polygon, enabling NFT cross-chain functionality. ZetaChain plans to expand to more EVM chains in the future.

Additionally, as the largest L2 solution, **Superchain** hosts a robust ecosystem of chains. We are actively promoting the **Superchain ERC721 standard**, which will enable NFTs to seamlessly transfer across all Superchain ecosystem chains.

By combining ZetaChain and the Superchain ecosystem, we aim to enable NFTs to freely move across most EVM ecosystems, much like ERC20 tokens do today.
