MoonPay NFT Checkout: Partner Driven Flow

The Partner Driven flow is designed to allow your users to purchase NFTs using fiat currency, while you maintain control over the way your smart contract is called. This flow requires you to provide us with callData, which we will use to execute an on-chain transaction and call your smart contract.

Step 1: Ensure you meet our product pre-requisites

Before setting up NFT Checkout, you'll need to check you meet all the requirements to use our product.

You're looking to complete a sale on Ethereum or Polygon (more chains coming soon) and the NFTs are priced in their native network currency (i.e. MATIC or ETH)
The NFTs have a USD value of between $3 & $15,000.
