Minting ERC721 Tokens

Minting ERC721 tokens is a fundamental operation in the lifecycle of Non-Fungible Tokens (NFTs), allowing the creation of unique digital assets. The edeXa ERC721 SDK provides a streamlined method, mintToken, to perform this operation. This guide outlines the process and provides a code example for minting tokens.

---

Overview of the mintToken Method

The mintToken method enables the creation of new tokens within the ERC721 standard. Each minted token is unique and is associated with specific metadata through a unique URI.

---

Prerequisites

• Installation of the edeXa ERC721 SDK in your project.
• An authentication token obtained through the SDK's authentication method. This token is necessary to authorize your requests.

Sample Code Snippet

Here is a JavaScript code snippet demonstrating the use of the mintToken method:

import { ERC721, Network } from 'edeXa-sdk';
async function mintToken() {
  const settings = {
    network: Network.SANDBOX, // Or Network.MAINNET for production environments
  };
  const erc721 = new ERC721({
    ...settings,
    authorization: `Bearer ${token}`, // Replace `${token}` with your actual authentication token
  });

  const dataToMintToken = {
    tokenUrl: 'Enter the token URL', // Required URL for the token metadata
    chaincode: 'Optional smart contract name', // Managing tokens' smart contract name
    channel: 'Optional blockchain channel name', // Blockchain channel name
  };

  try {
    const mintTokenResponse = await erc721.mintToken(dataToMintToken);
    // Handle success
  } catch (error) {
    // Handle error
  }
}
