Nft Minter DApp

This project is developed by Ali Kaan Kiris for the Softtech-Akademi Solidity Development Program as use case purpose.

---

This is a DApp for minting NFTs on the Ethereum blockchain. It uses;

• Next.js for the frontend.

• notiflix for the notifications.

• supabase for the database.

• ethers for the Ethereum wallet.

• openzeppelin/contracts for the NFT contract.

• Solidity for contract development.

• hardhat for contract testing and deployment.

• sepolia-testnet for the testnet.

• infura for the testnet node.

• MetaMask for the wallet.

• etherscan for the testnet explorer.

Prerequisites

• Node.js
• Git
• Metamask
• VS Code or any other IDE

Run the app with one-click installable script

• At the project directory, open git-bash and run the following command:

./run-dev.sh

Getting Started

You can skip steps (3, 4, 5, 6, 7) if you have already have exist .env file. Do not forget keys might be expired and these are pre-defined environment variables for the testnet and use case purpose.

1. First, move to the project directory:

cd nft-minter-dapp

2. Install dependencies:

• you have to install Node.js first.
• then run the following command:

npm install

3. Create a .env file (whether not exists) in the root directory of the project and add the following variables:

NEXT_PUBLIC_RPC_URL=''
NEXT_PUBLIC_ETHERSCAN_KEY=''
NEXT_PUBLIC_PRIVATE_KEY=''
NEXT_PUBLIC_CONTRACT_ADDRESS=''
NEXT_PUBLIC_TREASURY_CONTRACT_ADDRESS=''
NEXT_PUBLIC_LIQUIDITY_CONTRACT_ADDRESS=''
NEXT_PUBLIC_SUPABASE_URL=''
NEXT_PUBLIC_SUPABASE_ANON_KEY=''

4. Register your own account to related apps and get your own keys:

• NEXT_PUBLIC_RPC_URL register infura here.
• NEXT_PUBLIC_ETHERSCAN_KEY register etherscan here.
• NEXT_PUBLIC_PRIVATE_KEY install metamask, create an account and set private key here.
• NEXT_PUBLIC_CONTRACT_ADDRESS your main contract address.
• NEXT_PUBLIC_TREASURY_CONTRACT_ADDRESS your treasury contract address %6 of the minted NFTs will be sent to this address.
• NEXT_PUBLIC_LIQUIDITY_CONTRACT_ADDRESS your liquidity contract address %4 of the minted NFTs will be sent to this address.
• NEXT_PUBLIC_SUPABASE_URL register supabase here.
• NEXT_PUBLIC_SUPABASE_ANON_KEY your supabase anon key.

5. Create nft table in supabase:

• Create a table named nft in supabase and add the following columns:
  • data type: jsonb
  • name type: text
  • address type: text
  • meta type: json

6. Change NftMinterDapp.sol Contract Addresses in the contracts directory.

• Change treasuryWallet with your own address inside constructor.
• Change liquidityWallet with your own address inside constructor.

7. Clean Compile Deploy Contracts with hardhat:

• run the following commands whenever you change the contract:

npm run sol:clean
npm run sol:compile

• run the following command to deploy the contract to sepolia testnet:

npm run sol:deploy

8. Run the app in the development mode:

npm run dev

9. Open http://localhost:3000 to view it in the browser.

Pages
