On free collections, our creator rewards program lets artists earn a share of the mint fee from their collectors. Learn more about creator rewards [here](https://support.highlight.xyz/knowledge-base/highlight-protocol/protocol-rewards/creator-rewards). Beyond free and fixed price sales, Highlight also supports 3 different kinds of auctions. ### Auctions on Highlight Highlight offers creators the ability to auction off their artwork. We currently support a few different auction methods: * **Ranked auctions** allow you to set a fixed supply (say, 100 items) and let many collectors bid. The top 100 bidders would each win a work, and the losing bidders would get a refund. * **Dutch auctions** start the bidding from the highest set value and will decrease at a predetermined pace until it reaches the specified lowest sale price. Collectors bidding earlier will pay a higher price, but ensure they get a piece. * **English auctions** start the bidding at a reserve price that you set, and subsequent bidders can offer more. At the end of a fixed time period, the piece goes to the winning bidder. Learn more about different auction types and how to set them up in the following sections. --- # Agent Instructions This documentation is published with GitBook.
