NFT Minting dApp Starter
A full stack dApp starter for minting NFTs built on Ethereum (Solidity) with Next.js (React).
Clone This Repo
git clone https://github.com/tomhirst/nft-minting-dapp-starter.git to get the files within this repository onto your local machine.
.env and fill out the
HARDHAT_CHAIN_ID environment variable. The port from the example file, if it’s free, will be fine in most cases.
Running The Smart Contract Locally
Compile the ABI for the smart contract using
npx hardhat compile.
If you’re successful, you’ll recieve a confirmation message of:
Compilation finished successfully
src/artifacts folder will be created in your project.
Deploy the smart contract to the local blockchain for testing with
npx hardhat node.
If you’re successful, you’ll be presented with a number of account details in the CLI. Here’s an example:
Account #0: 0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266 (10000 ETH) Private Key: 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
Then in a new terminal window,
npx hardhat run scripts/deploy.js --network localhost.
If you’re successful, you’ll get something like the following CLI output:
Minter deployed to: 0x9fE46736679d2D9a65F0992F2272dE9f3c7fa6e0
Adding A Local Account To MetaMask
Open your MetaMask browser extension and change the network to
Next, import one of the accounts by adding its Private Key (for example,
0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 to MetaMask.
If you’re successful, you should see the a balance resembling something like
10000 ETH in the wallet.
Connecting The Front-End
.env set the
NEXT_PUBLIC_MINTER_ADDRESS environment variable to the address your smart contract was deployed to. For example,
In a new terminal window, load the front-end with
npm run dev. If you want to use an alternate port from
npm run dev -- --port=1234, or whatever port number you prefer.
Demo’ing The Functionality
Once set up, go to
localhost:3000 (or whatever post number you used), to view your dApp in the browser.
First, connect your wallet by clicking
Connect wallet. Ensure you’re connected to the
Localhost 8454 network in your MetaMask extension. Select the wallet that you imported earlier.
You can now test minting tokens, between 1 and 10 per transaction, by filling out the input with your desired amount and clicking the
If you successfully mint a number of NFTs, you should see the
Tokens minted amount increment.
Switching accounts in MetaMask will update the wallet address in the top right hand corner. Disconnecting all accounts will prompt you to connect your wallet.
All state is retained on browser refresh.
Editing The Front-End
To modify the front page of your application, edit
All TailwindCSS classes are available to you.
To lint your front-end code, use
npm run lint.
To test the smart contract, run
npx hardhat test.
Basic tests can be found in
- Show the funds available in the connected account’s wallet
- Add common owner functionality to the contract
- Reserve tokens
- Flip sale state
- Set starting index
- Set base URI for asset metadata
- Set provenance hash
- Withdraw funds
- Attach image data to minted tokens with IPFS
- Deploy to the Ropsten test network
- Introduce code style rules and linting
- Write more extensive tests
- Create a TypeScript fork
