Ethereum NFT Markplace BoilerPlate

tlrx · December 30, 2021, 9:45am

I have cloned https://github.com/ethereum-boilerplate/ethereum-nft-marketplace-boilerplate and added server url and application key in .env file.
After this I am getting an error, that o Smart Contract Details Provided. Please deploy smart contract and provide address + ABI in the MoralisDappProvider.js file

Is there any guide how to get these ?

you may need to deploy a smart contract

Hi tlrx - you will need to copy the smart contract which is here

github.com

ethereum-boilerplate/ethereum-nft-marketplace-boilerplate/blob/main/src/contracts/marketplaceBoilerplate.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.4;

import "github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/utils/Counters.sol";
import "github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/ERC721.sol";
import "github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/security/ReentrancyGuard.sol";

contract marketPlaceBoilerPlate is ReentrancyGuard {
    using Counters for Counters.Counter;
    Counters.Counter private _itemIds;
    Counters.Counter private _itemsSold;
    
     address public owner;
     
     constructor() {
         owner = msg.sender;
     }
     
     struct MarketItem {
         uint itemId;

AND then compile it on REMIX: https://remix.ethereum.org/
How??? see below

Create a new file - you see a small plus icon on the left hand window pane section.
paste the copied contract from Github
Name it marketPlaceBoilerplate.sol
compile it by clicking the compile button (this should be the 3rd ICON on the extreme left pane)
In the compile section make sure the version of compiler (top dropdown) is 0.84
Press the big Blue Compile button
and it should compile.
THEN
Scroll to the bottom of the section to see the ABI which you can copy by clicking the ABI icon.
To deploy the contract and get your transaction contract address please click the deploy button which is
compile it by clicking the compile button (this should be the 4th ICON on the extreme left pane). Scroll to the bottom of the section to see the Contract address which you can copy by clicking the copy icon.

Hope it helps.
