mintOnMetadata

Mint on previously created metadata. Make sure to attach the required price! If the metadata was created using the ftAddress parameter, you need to make sure to pass the same the ftAddress to this method.

If you want specific token IDs, you can specify those via the tokenIds parameter. If your token IDs are already in use, this will cause a smart contract panic. You can also mint multiple tokens without specifying token IDs using the amount parameter. Make sure that there is no mismatch between your tokenIds and amount parameters.

The nftContactId can be supplied as an argument or through the TOKEN_CONTRACT environment variable.

If you want to mint on a v1 smart contract, please use the corresponding method.

As with all new SDK api methods, this call should be wrapped in execute and passed a signing method. For a guide showing how to make a contract call with mintbase-js click here

mintOnMetadata(args: MintOnMetadataArgs): NearContractCall

mintOnMetadata takes a single argument of type MintOnMetadataArgs

export type MintOnMetadataArgs =  {
  //the contractId from which you want to mint, this can be statically defined via the mbjs config file
  contractAddress?: string;
  //the ID of the metadata you wish to mint on
  metadataId: string;
  //the owner of the minted tokens
  ownerId: string;
  // number of tokens to mint
  amount?: number;
  //pre-specified token IDs
  tokenIds?: string[];
  //price for minting on token in NEAR
  price: number;
};

React example

Example usage of mint method in a hypothetical React component:

MintOnMetadataComponent.ts
import { useState } from 'react';
import { useWallet } from '@mintbase-js/react';
import { execute, mintOnMetadata, MintOnMetadataArgs } from '@mintbase-js/sdk';


export const MintOnMetadataComponent = ({ contractAddress, metadataId, ownerId, price }: MintOnMetadataArgs): JSX.Element => {

  const { selector } = useWallet();

  const handleMintOnMetadata = async (): Promise<void> => {

    const wallet = await selector.wallet();

    await execute(
      mintOnMetadata({ contractAddress, metadataId, ownerId, price })
    );

  }

  return (
    <div>
      <button onClick={handleMintOnMetadata}>
        Mint on metadata
      </button>
    </div>
  );
};
