This research was conducted to apply other ways of transacting modern digital art using blockchain technology. This technology can help artists easily sell their works of art by verifying the ownership of digital art, where previously only physical art could do it. The use of NFT (Non-Fungible Tokens) in publishing digital artworks in a digital marketplace media platform can be a solution for the copyright of work in the future for artists in Indonesia. The developed Marketplace platform applies the Polygon Matic blockchain technology and a smart contract from a third party, namely MetaMask, to secure and process every transaction that occurs to provide security and convenience in digital commerce.
