Integration guide

⚒️ Fiat and cross-chain payments

Start accepting fiat and cross-chain payments for your NFT sale in 15 minutes. If you are a marketplace or a launchpad, read this.

Before starting, note that Crossmint can only be used for the sale of NFTs. Make sure that what you are selling is not included in our list of prohibited and restricted businesses which includes gambling, securities, unfair or predatory products, and other sensitive categories.

If you want to build the integration on testnet, follow the integration guide using our staging console: https://staging.crossmint.com/console. If you are ready to ship in production, go to https://crossmint.com/console.
