Royalty Customization allows creators of NFTs to define specific royalty percentages that they will receive from secondary sales of their digital assets. This feature empowers artists and creators to establish a sustainable revenue stream, ensuring they benefit from the ongoing value of their work as it changes hands in the marketplace. By providing flexibility in setting up these royalties, creators can tailor their earnings to reflect their contributions and the value of their creations over time, fostering a more equitable ecosystem in the NFT space.
