# Mint NFTs资产

Mint NFT 到 MCS Opensea Collection

```
mintAsset(sourceFileUploadId, nftObject)
```

下面的代码示例将上传的文件铸造为在 Opensea 上可查看的 NFT。创建一个 NFT 对象并提供该文件的payload\_cid。NFT 对象遵循[OpenSea元数据标准](https://docs.opensea.io/docs/metadata-standards)。

```
require('dotenv').config()
const { mcsSDK } = require('js-mcs-sdk')

// set up js-mcs-sdk
const mcs = new mcsSDK({
  privateKey: process.env.PRIVATE_KEY,
  rpcUrl: process.env.RPC_URL,
})

async function main() {
  // ENTER PARAMETERS
  const SOURCE_FILE_UPLOAD_ID = 0
  const IPFS_URL = ''
  const NFT_NAME = ''

  const NFT_DESCRIPTION = '' // optional

  const nft = {
    name: NFT_NAME, // the name of your NFT
    image: IPFS_URL, // asset URI, images will render on Opensea
    external_url: IPFS_URL, // Opensea will provide a link to view the source
    description: NFT_DESCRIPTION, // description of your NFT
    attributes: [], // NFT attributes displayed on Opensea
  }

  const mintTx = await mcs.mintAsset(SOURCE_FILE_UPLOAD_ID, nft)
  console.log(mintTx)
}

main()
```
