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 Fireblocks Hardhat Plugin Documenation, Fireblocks Local JSON RPC and Fireblocks Web3 provider .
Make sure you go through these 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.
