Using Hardhat Here is a detailed explanation of what Hardhat is and a step-by-step guide on how to deploy a TEP1155 contract using hardhat:
What is Hardhat ?
Hardhat is a development environment for Ethereum and Ethereum-compatible blockchains. It provides a comprehensive toolset for smart contract development, testing, debugging, and deployment.
Step-by-Step Guide to Deploy Contract
Follow these steps to deploy a TEP1155 contract using Hardhat:
1. Install Hardhat
Ensure you have Node.js and npm installed. Then, create a new directory for your project and initialize it with Hardhat:
Copy mkdir TEP1155Project
cd TEP1155Project
npm init - y
npm install -- save - dev hardhat
2. Initialize Hardhat Project
Run the following command to initialize a Hardhat project:
Follow the prompts to create a new Hardhat project, selecting the appropriate options for your needs.
3. Write the Contract
Create a new file TEP1155NFT.sol
in the contracts
directory and add your TEP1155NFT code:
Copy // SPDX-License-Identifier: MIT
pragma solidity 0.8.20;
import "@openzeppelin/contracts/token/ERC1155/ERC1155.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
contract TEP1155NFT is ERC1155, Ownable {
constructor(address initialOwner) ERC1155("") Ownable(initialOwner) {}
function mint(address account, uint256 id, uint256 amount, bytes memory data)
public
onlyOwner
{
_mint(account, id, amount, data);
}
function mintBatch(address to, uint256[] memory ids, uint256[] memory amounts, bytes memory data)
public
onlyOwner
{
_mintBatch(to, ids, amounts, data);
}
}
4. Write the Deployment Script
Create a new file deploy.js
in the scripts
directory to write your deployment script:
Copy async function main () {
const [ deployer ] = await ethers .getSigners ();
console .log ( "Deploying the contracts with the account:" , await deployer .getAddress ());
console .log ( "Account balance:" , ( await deployer .getBalance ()) .toString ());
const TEP1155NFT = await ethers .getContractFactory ( "TEP1155NFT" );
const token = await TEP1155NFT .deploy ();
await token .deployed ({ gasLimit : 6000000 });
console .log ( "TEP1155NFT address:" , token .address);
}
main ()
.then (() => process .exit ( 0 ))
.catch ((error) => {
console .error (error);
process .exit ( 1 );
});
5. Configure Network
Make sure to install the suggested versions of the packages:
Copy npm install --save-dev @nomiclabs/hardhat-ethers@^2.2.3 @nomiclabs/hardhat-waffle@^2.0.6 @openzeppelin/contracts@^5.0.2 @uniswap/v3-periphery@^1.0.1 bignumber.js@^9.1.2 dotenv@^16.4.5 ethereum-waffle@^4.0.10 ethers@5.4 hardhat@^2.22.4
Create a ` .env`
file in the root of your project directory to store your private key.
Copy // In .env file
YOUR_PRIVATE_KEY = "YOUR_PRIVATE_KEY"
Update the hardhat.config.js
file to include network configurations:
Copy require ( "@nomiclabs/hardhat-waffle" );
/** @type import('hardhat/config').HardhatUserConfig */
const privateKey = process . env . YOUR_PRIVATE_KEY ;;
module . exports = {
solidity : {
version : "0.8.20" ,
settings : {
optimizer : {
enabled : true ,
runs : 1000 ,
details : {yul : false } ,
}
}
} ,
networks : {
taral : {
chainId : 4440 ,
url : "https://devnet-taral-rpc1.tarality.com" ,
accounts : [privateKey] ,
} ,
} ,
};
6. Deploy the Contract
Run the deployment script with Hardhat:
Copy npx hardhat run scripts / deploy .js -- network taral
Congratulations! You have successfully deployed your TEP1155 token contract using Hardhat. This guide covered the entire process from setting up the Hardhat project to deploying the contract.
