Deploying an NFT Collection

Suggest Edits

Prerequisites

Overview

You can deploy smart contracts using The Fireblocks Hardhat plugin integration

Create your ERC-721 collection

You can create your own NFT collection using the common ERC-721 standard.

For this example, we’ll name our collection “Space Bunnies”.

There are some great tools to help you do this pretty easily. This example was pre-generated using the Contracts Wizard by OpenZeppelin.

pragma solidity ^0.8.4;

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
import "@openzeppelin/contracts/utils/Counters.sol";

contract SpaceBunnies is ERC721, ERC721URIStorage, Ownable {
    using Counters for Counters.Counter;

    Counters.Counter private _tokenIdCounter;

    constructor() ERC721("Space Bunnies", "SPCB") {}

    function safeMint(address to, string memory uri) public onlyOwner {
        uint256 tokenId = _tokenIdCounter.current();
        _tokenIdCounter.increment();
        _safeMint(to, tokenId);
        _setTokenURI(tokenId, uri);
    }

    // The following functions are overrides required by Solidity.

    function _burn(uint256 tokenId) internal override(ERC721, ERC721URIStorage) {
        super._burn(tokenId);
    }

    function tokenURI(uint256 tokenId)
        public
        view
        override(ERC721, ERC721URIStorage)
        returns (string memory)
    {
        return super.tokenURI(tokenId);
    }
}

OpenZeppelin required

To run the generated code, you also need to install the OpenZeppelin contracts package from NPM.

In your project directory, run: npm install @openzeppelin/contracts.

You are ready to go!

Check out the Ethereum Smart Contract Development guide. Make sure you go through it and deploy the above contract as explained there, using your choice of available options.

Hardhat Deployment

Hardhat is the go-to market solution for easily deploying contracts. We highly recommend that you choose this option if you feel comfortable with going through the configuration process.
