Deploying an ERC-721 token contract for NFTs on Vanar chain is a straightforward process that is exact similar to what is explained in ''. The only difference is down to the smart contract level which is different to an ERC20 token contract.
Below are the libraries and tools used for this tutorial:
OpenZeppelin - used for standard ERC20 base contract that is well tested and used by many production scale projects
Hardhat - is a tool and an environment that helps you compile, build, deploy and test you smart contracts along many other features.
Node.js and npm installed on your machine.
Basic knowledge of Solidity and Ethereum development.
If you don't already have a Hardhat project, you can create one by following these steps:
Create a new directory for your project and navigate to it in the terminal:
Initialize a new Node.js project with npm:
Install Hardhat as a development dependency:
Initialize Hardhat in your project:
Follow the prompts to configure your project.
Now, you'll need to create a Solidity smart contract for your ERC-721 token. Create a new file called Token721.sol
in the contracts
directory.
Here's a basic example of an ERC-721 contract:
Make sure to install OpenZeppelin's ERC-721 library if you haven't already:
In your Hardhat project, configure the deployment by modifying the hardhat.config.js
file. You can specify the network, account, and other settings for deployment.
Here's an example configuration:
Step 4: Deploy the ERC-20 Token
Now, you can deploy your ERC-20 token using Hardhat. Create a deployment script in the scripts
directory (e.g., deploy721.js
) to deploy the contract:
Run the deployment script using Hardhat:
Replace <network_name>
with the configured VANAR network you want to deploy the token on.
That's it! You've deployed an ERC-721 token contract using Hardhat on VANAR. Make sure to test your token and handle any additional functionalities such as transfers, approvals, and more if needed.
