Crossmint’s Smart Wallets can be the backbone of a user’s account in your app. You can use them along with other Crossmint and partner APIs to execute critical functions in your app. This page will highlight common use cases, including:

  1. Minting and editing dynamic NFTs
  2. Buying an NFT with a Credit Card
  3. Interacting with a whitelabel NFT marketplace in your app

All of these will require creating a smart wallet first. Haven’t created one yet? Learn how to create one here

Minting dynamic NFTs

Leveraging Crossmint’s minting tools, you can gas-lessly deploy a contract, and mint NFTs from it to a Crossmint Smart Wallet

Server-side API scopes required: nfts.create Client-side API scopes required: wallets.create

The only specific requirement when minting to Crossmint’s smart wallet is that you must pass the wallet address that you created for the user as the recipient wallet.

             //truncated for brevity
         }
     }'

Using your own contract? You can still mint against your smart contract gas-lessly by using the sendTransaction function.
