The Smart Contract Support feature allows users to create and manage smart contracts for each NFT in a collection. This functionality ensures that ownership of NFTs is verifiable on the blockchain, enabling seamless transferability between users. Additionally, the smart contracts can be programmed to include royalty structures, allowing creators to earn a percentage of sales whenever their NFTs are resold. This feature is crucial for maintaining trust and transparency in the NFT marketplace, as it automates and secures the processes of ownership transfer and royalty distribution.
