3. Choose the recipient for your NFT

Crossmint allows you to deliver NFTs to two kind of addresses:

Wallet addresses, or
Email addresses: in this modality, Crossmint automatically generates a secure MPC backed custodial wallet for the email, and delivers the NFT inside.

Supported Blockchains

The Minting API requires each request to specify the blockchain for the NFT, using the param name in the recipient field. The following blockchains are supported in the Minting API:

Blockchain	Param Name
Polygon	`polygon`
Solana	`solana`

Sending NFTs to blockchain addresses

To mint an NFT directly to an existing blockchain address, the following recipient format is used:

<chain>:<address>

Examples of sending to a blockchain address

Polygon: polygon:0x123...
Solana: solana:3Q5...

Sending NFTs to email addresses

To mint an NFT and send it to an email address, the following recipient format is used:

email:<email_address>:<chain>

Examples of sending to an email address

Polygon: email:[email protected]:polygon
Solana: email:[email protected]:solana

The NFT can then be accessed by logging into Crossmint with the specified email address:
