You can deliver items to three kinds of recipients when using Crossmint:

​
Digital Products

For digital items (NFTs, tokens, etc.), you can specify one of the following recipient types:
  • Email address: Crossmint automatically generates a secure MPC-backed custodial wallet for the user's email and delivers the item inside that new wallet. Email addresses are case-insensitive.
  • Wallet address: Directly specify a blockchain wallet address. Receipt will be delivered to the email address specified in payment.receiptEmail. This could be a user-owned wallet (e.g., MetaMask, Phantom, etc.) or a wallet you manage. The format depends on the blockchain: - Ethereum/EVM chains: 0x1234567890abcdef1234567890abcdef12345678 - Solana: 5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty - Other chains: Contact support for format requirements

​
Physical Products

For physical items, you must provide:
  • Email address: Required for receipt delivery (legal requirement)
  • Physical address: Required shipping information including name, address, city, state, postal code, and country

​
Specifying the Recipient

For Headless Checkout, you specify the recipient when creating or updating an order.

​
Recipient by Email

When specifying a recipient by email, Crossmint will automatically create a secure custodial wallet on the fly for that email address: 
POST /api/2022-06-09/orders
{
  "recipient": {
    "email": "user@example.com" // Email address of the recipient
  },
  "locale": "en-US",
  "payment": {
    "method": "ethereum-sepolia",
    "currency": "eth",
    "payerAddress": "0x1234abcd...",
    "receiptEmail": "user@example.com"
  },
  "lineItems": {
    "collectionLocator": "crossmint:cosdahdasda",
    "callData": {
      "totalPrice": "0.0001",
      "quantity": 1
    }
  }
}
The recipient will be able to access their purchased items by logging into their Crossmint wallet in staging or mainnet.

​
Recipient by Wallet Address

To deliver items directly to a specific blockchain wallet address: 
POST /api/2022-06-09/orders
{
  "recipient": {
    "walletAddress": "0x1234567890abcdef1234567890abcdef12345678" // For EVM chains
    // or
    // "walletAddress": "5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty" // For Solana
  },
  "locale": "en-US",
  "payment": {
    "method": "ethereum-sepolia",
    "currency": "eth",
    "payerAddress": "0x1234abcd...",
    "receiptEmail": "user@example.com" // Required when using wallet address
  },
  "lineItems": {
    "collectionLocator": "crossmint:cosdahdasda",
    "callData": {
      "totalPrice": "0.0001",
      "quantity": 1
    }
  }
}
If specifying a recipient by wallet address, ensure the address is valid for the chain your collection is on, which may differ from the chain the payment is performed on.

​
Physical Product Recipients

Physical Address Format Extend the recipient object with the physicalAddress object. These are the properties (note the required vs optional fields): 
{
  "recipient": {
    "email": "user@example.com",
    "physicalAddress": {
      "name": "John Doe", // required - Full name of the recipient
      "line1": "123 Main St", // required - Street address, P.O. box, company name, c/o
      "line2": "Apt 4B", // optional - Apartment, suite, unit, building, floor, etc.
      "city": "San Francisco", // required - City, district, suburb, town, or village
      "state": "CA", // required for US addresses - State, county, province, or region
      "postalCode": "94105", // required - ZIP or postal code
      "country": "US" // required - Two-letter country code (ISO 3166-1 alpha-2)
    }
  }
}
Note: You must include the email address of the recipient in the recipient object so an email receipt can be sent to the customer (this is a legal requirement for physical product deliveries).
Currently, only US addresses are supported for physical product deliveries.
 When purchasing physical products, providing a physical address is required. If you don’t provide it in the initial order, you can update the order it later: 
POST /api/2022-06-09/orders
{
  "recipient": {
    "email": "buyer@example.com", // Email address of the recipient
    "physicalAddress": {
      "name": "John Doe",
      "line1": "123 Main St",
      "line2": "Apt 4B", // optional
      "city": "San Francisco",
      "state": "CA",
      "postalCode": "94105",
      "country": "US"
    }
  },
  "locale": "en-US",
  "payment": {
    "method": "ethereum-sepolia",
    "currency": "eth",
    "payerAddress": "0x1234abcd...",
    "receiptEmail": "buyer@example.com" // Required for physical products
  },
  "lineItems": {
    "collectionLocator": "crossmint:cosdahdasda",
    "callData": {
      "totalPrice": "0.0001",
      "quantity": 1
    }
  }
}
If you create an order with a physical product without specifying a physicalAddress, the order’s quote status will become requires-physical-address. After providing the physical address, the order status will update and include the necessary payment.preparation parameters to proceed with payment. Learn more about payment preparation in the payment phase documentation.
