Setting Operator for a Specific Token

Granting operator permissions for a specific token is a crucial feature of the ERC721 standard, allowing token owners to delegate control over individual tokens. The setOperator method in the edeXa ERC721 SDK facilitates this delegation process. This guide provides a comprehensive overview and a code example for setting an operator for a specific token.

---

Overview of the setOperator Method

The setOperator method allows token owners to authorize an operator to manage a particular token on their behalf. This can include actions like transferring the token, depending on the permissions granted.

---

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 setOperator method:

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

  const dataToSetOperator = {
    operator: 'Enter the username of the user to set as operator for the token', // Required
    tokenId: 'Enter the tokenId to approve for spending', // Required
    chaincode: 'Optional smart contract name', // Managing tokens' smart contract
    channel: 'Optional blockchain channel name', // Blockchain channel
  };

  try {
    const setOperatorResponse = await erc721.setOperator(dataToSetOperator);
    // Handle success
  } catch (error) {
    // Handle error
  }
}
