NFT Marketplaces & Launchpads

Add fiat and cross-chain crypto payments to your platform

NFT sales are not self-serve in production. You can build and test NFT sales in staging. In production, Crossmint only enables them by exception for enterprise programs, and at this moment is not onboarding new projects. If yours is part of a broader payments initiative, contact sales. Minting and airdrops stay available.

Additional services offered to marketplaces and launchpads

Crossmint offers additional services to marketplaces and launchpads, including:

• Custom branding and email receipts

• Dedicated Slack channel with Crossmint’s support team

• Custom SLAs

• APIs to register new collections programmatically

• Increased purchase limits

• Cart mode and ability to sweep the floor

…and more

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.

FAQs

Where can I test it?

Crossmint powers most major launchpads across chains. You can see in action on Manifold and Highlight.

How does creator and collection verification work?

For primary sales, Crossmint requires creators to do light KYC and confirm their project meets Crossmint’s content policy. 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.
