Minting NFTs

Use the following mutation to mint up to 700 NFTs in one single atomic operation. If successful, all NFTs are minted, and their corresponding tokenIds are returned. If the operation fails, no NFTs are minted. Batching multiple mints into one atomic operation can simplify and streamline application logic significantly.

The mintAsync mutation sends a mintNFT transaction to the blockchain and returns a trackingId, which can be used to check the minting status later. This approach is common in blockchain interactions and is recommended because it provides faster responses and prevents the API from blocking during large minting operations.

The following example mints two NFTs, atomically, to different initial owners:

mutation MintNFT {
  mintAsync(
    input: {
      chainId: "137"
      contractAddress: "0x370d32d6fcef88e0a008d23a1a602f33b6fcf251"
      tokens: [
        {
          mintTo: ["0x4E6Da57f62b9954fBb6bAb531F556BE08E128e75"]
          name: "Intro to LAOS NFT"
          description: "This is my first LAOS Mint!"
          attributes: [{ trait_type: "Level", value: "Introduction" }]
          image: "ipfs://QmPC9LrMuN6YkcJBRhBcWiDcS4ndkx3cwXdVNQ59PY8EBq"
        },
        {
          mintTo: ["0xe688b84b23f322a994A53dbF8E15FA82CDB71127"]
          name: "Advanced concepts about LAOS"
          description: "This is my second LAOS Mint!"
          attributes: [{ trait_type: "Level", value: "Advanced" }]
          image: "ipfs://QmPC9LrMuN6YkcJBRhBcWiDcS4ndkx3cwXdVNQ59PY8EBq"
        }
      ]
    }
  ) {
    tokenIds
    status
    trackingId
  }
}

Expected response:

{
  "data": {
    "mintAsync": {
      "tokenIds": [
        "46231769497101023895754357762572931969783788518045090509665456129453327552117",
        "14847791404436078325473592906636402279408597633171402217703076291487718845731"
      ],
      "status": "PENDING",
      "trackingId": "6283:0xf744ffc58c8f1544fa54f4282eaf9974b932d99022f6b37f533f5a23c1cb9153"
    }
  }
}

Checking Mint Status​

Use the mintResponse query with the trackingId to check the status of a mint operation.

query mintNFTResponse {
  mintResponse(
    trackingId: "6283:0xf744ffc58c8f1544fa54f4282eaf9974b932d99022f6b37f533f5a23c1cb9153"
  ) {
    status
  }
}

Example response:

{
  "data": {
    "mintResponse": {
      "status": "SUCCESS",
    }
  }
}

Synchronous Minting​

The mint mutation mints NFTs and returns the result, including the success status. It is ideal for synchronous processes, but the response may take several seconds and could block the API for longer during large minting operations.

Here is the synchronous version of the example above:

mutation MintNFT {
  mint(
    input: {
      chainId: "137"
      contractAddress: "0xc7471bab04d2f53f6e79c754e19fdbd1e5a4a3c3"
      tokens: [
        {
          mintTo: ["0x4E6Da57f62b9954fBb6bAb531F556BE08E128e75"]
          name: "Intro to LAOS NFT"
          description: "This is my first LAOS Mint!"
          attributes: [{ trait_type: "Level", value: "Introduction" }]
          image: "ipfs://QmPC9LrMuN6YkcJBRhBcWiDcS4ndkx3cwXdVNQ59PY8EBq"
        },
        {
          mintTo: ["0xe688b84b23f322a994A53dbF8E15FA82CDB71127"]
          name: "Advanced concepts about LAOS"
          description: "This is my second LAOS Mint!"
          attributes: [{ trait_type: "Level", value: "Advanced" }]
          image: "ipfs://QmPC9LrMuN6YkcJBRhBcWiDcS4ndkx3cwXdVNQ59PY8EBq"
        }
      ]
    }
  ) {
    tokenIds
    success
  }
}

Expected response:

{
  "data": {
    "mint": {
      "tokenIds": [
        "46231769497101023895754357762572931969783788518045090509665456129453327552117",
        "14847791404436078325473592906636402279408597633171402217703076291487718845731"
      ],
      "success": true
    }
  }
}
