When someone buys your NFT, the program transfers the SOL amount from the buyer to the seller, and then unlocks the NFT which is sent to the buyer. Solanart uses both on-chain and off-chain data. The off-chain data is stored on a database and used to display all the NFT for sale on the main page, while the on-chain data is used when displaying NFT one by one, or from the 'My NFTs for sale' section in the 'Wallet' tab. The choice of using the database for the main page was made to allow easy sorting of all NFTs per attributes, price, oldest or newest sales etc. On-chain data provides a secure and decentralized experience. In fact, the marketplace could be fully decentralized, but handling multiple thousands of NFTs for sale and displaying them with filters on the main page is currently not an option because of the request limitation on the Solana Network.
