Currently, I am in the process of transferring my NFT to a marketplace
pragma solidity ^0.8.7;
import "@openzeppelin/contracts/utils/Counters.sol";
import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
import "@openzeppelin/contracts/security/ReentrancyGuard.sol";
import "hardhat/console.sol";
contract NFT is ERC721URIStorage {
using Counters for Counters.Counter;
Counters.Counter private _tokenIds;
address contractAddress;
constructor(address marketplaceAddress) ERC721("Heliopolis NFT", "HNFT") {
contractAddress = marketplaceAddress;
}
function createToken(string memory tokenURI) public returns (uint256) {
_tokenIds.increment();
uint256 newItemId = _tokenIds.current();
_mint(msg.sender, newItemId);
_setTokenURI(newItemId, tokenURI);
setApprovalForAll(contractAddress, true);
return newItemId;
}
function transferToken(address from, address to, uint256 tokenId) external {
require(ownerOf(tokenId) == from, "From address must be token owner");
_transfer(from, to, tokenId);
}
function getContractAddress() public view returns (address) {
return contractAddress;
}
}
As part of my implementation using web3modal:
import { ethers } from 'ethers';
import Web3Modal from 'web3modal';
import { nftMarketplaceAddress, nftAddress } from 'utils/contracts';
import { nftMarketplaceAbi } from 'utils/nftMarketplaceAbi';
// eslint-disable-next-line @typescript-eslint/no-explicit-any
export const resellNft = async (nft: any) => {
try{
const web3Modal = new Web3Modal();
const connection = await web3Modal.connect();
const provider = new ethers.providers.Web3Provider(connection);
const signer = provider.getSigner();
const contract = new ethers.Contract(nftMarketplaceAddress, nftMarketplaceAbi, signer);
// putItemToResell invokes the transferToken(*) method mentioned above
const transaction = await contract.putItemToResell(nftAddress, nft.tokenId, nft.price,
{
gasLimit: 1000000,
gasPrice: ethers.utils.parseUnits("10", "gwei"),
value: ethers.utils.parseUnits("0.001", "ether"),
}
);
const response = await transaction.wait();
console.log(response);
}catch (e:any){
throw e;
}
}
If an error such as
ERC721: transfer caller is not owner nor approvedtransferFrom() on your behalf. It's worth noting that the NFT contract includes the approve method inherited from its super class. Is there a way around this issue?
