A collection is a group of NFTs existing in the same contract! On LUXY each Collection is a Smart Contract in one of the networks supported by LUXY. The contract defines the rules and possibilities for each token. LUXY Marketplace reads the information and enables users to transact the NFTs from the collections listed on LUXY. ## Can I list my NFT project on LUXY? The purpose of LUXY Marketplace is to be an open market for NFT commerce. If your project has an NFT Smart Contract already deployed you can list it on LUXY if it is compatible. ## Can I have more than one collection on LUXY? Yes, you can add as many collections you want to the marketplace! Please note that you can configure and customize only the ones you own or manage. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.luxy.io/help-center/luxy-marketplace/key-concepts/collections.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
