 The ERC-721 standard packs any file format into permanently stored content on the blockchain. Thanks to Moonbeam’s and Astar’s EVM compatibility, it can be deployed quickly and efficiently with Apillon.
 
+Native NFTs on Unique Network are streamlined, blockchain-integrated tokens that offer simplicity, speed, cost-efficiency, and enhanced security, eliminating the complexities of traditional smart contract-based NFTs.
