    ### Integrating Crossmint into a marketplace

    Integrating Crossmint into a marketplace can be as simple as
    adding five lines of code, depending on the level of customization required.

    The following snippet would be sufficient to render a button that enables
    the purchase of one of your listings with credit card.

    <CodeGroup>
      ```jsx EVM theme={null}
      <CrossmintProvider apiKey="_YOUR_CLIENT_API_KEY_">
        <CrossmintHostedCheckout
          lineItems={{
              tokenLocator: "ethereum:0xbC…307e:7777",
              callData: {
                totalPrice: "0.1"
              }
            }}
        />
      </CrossmintProvider>
      ```

      ```jsx Solana theme={null}
      <CrossmintProvider apiKey="_YOUR_CLIENT_API_KEY_">
        <CrossmintHostedCheckout
          lineItems={{
              tokenLocator: "solana:4oDd…x6NC",
              callData: {
                totalPrice: "0.1",
                buyerCreatorRoyaltyPercent: 100
              }
            }}
        />
      </CrossmintProvider>
      ```
    </CodeGroup>

    ### FAQs

    <Accordion title="Where can I test it?">
      Crossmint powers most major launchpads across chains. You can see in action on [Manifold](https://app.manifold.xyz/c/sleeping-potato) and [Highlight](https://highlight.xyz/mint/6525a4b606bc6fa5b8acdcfa).
    </Accordion>

    <Accordion title="How does creator and collection verification work?">
      For primary sales, Crossmint requires creators to do <Tooltip tip="Takes 2 minutes and 30 seconds on average">light KYC</Tooltip> and confirm their project meets Crossmint's [content policy](https://drive.google.com/file/d/1kXv5gX7C8xHJFDAnCQTNUmXrDP05YYk1/view). There are multiple options to achieve this:

      * You can conduct project verification yourself.
      * You can send creators to register their collection at Crossmint.com and share their collectionID with you, so you can pass it to the digital asset checkout.
      * (Coming soon) You can use Crossmint's collection verification SDK to verify creators directly on your site.
