const result = await ExpressSDK.erc721.collection.batchMint(
  web3, // Web3 instance configured with metamask provider
  collectionAddress, // Address of the collection
  minterAddress, // Address of Minter
  totalNFT, // Number of tokens to mint
  arraytokenURI, // array of TokenURI String for each token
  royalties // array of royalties for each token

The token Ids for minted tokens can be retrieved through the respective emitted events. (Transfer and RoyaltiesSetForTokenId events are emitted for each token minted through batchMint.)
