Feature for managed partners only

This is a feature intended for managed partners. If you are not a managed partner and would like to become one, please reach out to us on our #dev-discussion channel on Discord.

If you are a managed partner, your partner success manager needs to set up a commercial partnership with MoonPay for you. Please reach out to them to facilitate this.

We have partnered with MoonPay to enable you to integrate their NFT Checkout feature so you can build applications that allow your users to purchase NFTs directly on Immutable with a credit card - no ETH or other ERC20 token required!

This primary sales flow is available in the Link SDK v1.35.7+ and is a collaboration between Immutable and MoonPay. It requires you to register your intent to use the service with us, and to have commercial agreement between you & MoonPay.

Once you have been approved, to initialize the NFT Checkout process you need to call the nftCheckoutPrimary function:

await link.nftCheckoutPrimary({
sellerWalletAddress: '0x001', // L2 wallet address of the seller
contractAddress: '0x002', // NFT contract address
offerId: 'new_offer', // The identifier for the "offer"


  • sellerWalletAddress - L2 wallet address of the seller, funds will be send to this address
  • contractAddress - NFT contract address
  • offerId - An identifier that represents what will be minted.

In the cases where purchasers know what they're purchasing (such as a specific pfp) offerId could be the token ID (i.e. 420) and in other cases where they dont know what they're purchasing (such as a loot box) it could be something like silver-chest. This is simply a way to render an item in the cart, and doesnt need to tie to the actual NFT asset directly.

Handling the offerID

Note that primary sales involve taking a payment before the mint occurs. Because the asset doesnt exist yet, we've included an offerId instead of an asset ID. Therefore in order to successfully render the checkout with the information seen below (Offer title, and image) - you will need to be a managed partner with Immutable.

This displays the Link UI with loaded MoonPay widget:
