This project contains all tutorial files from the How to mint a music NFT: Dropping fire tunes with Chainstack IPFS Storage tutorial, originally published on the Chainstack Developer Portal: Web3 [De]Coded.

This repository contains scripts and contracts needed to create a new wallet, check its balance, compile an NFT contract, and mint music NFTs using pre-set metadata on the Ethereum network with Chainstack IPFS Storage, Hardhat and Web3js.

• Contract: Goerli
• Contract: Sepolia
• Music NFT: Goerli
• Music NFT: Sepolia
• OpenSea

• Chainstack endpoint
• Dotenv
• Hardhat with Web3js
• OpenZeppelin contracts
• Axios
• Form data

1. Clone or fork this repo to a preferred location by running in CLI:

git clone https://github.com/chainstacklabs/music-nft-minter-tutorial-repo.git  

2. Install dependencies by running in CLI:

npm ci  

3. Rename .env.sample to .env and fill in your endpoint URLs for each network, then your Chainstack and Etherscan API keys:

GOERLI="https://your-goerli-endpoint-here"
SEPOLIA="https://your-sepolia-endpoint-here"
MAINNET="https://your-mainnet-endpoint-here"
CHAINSTACK="Bearer y0urChainstackAPIkeyHer3"
ETHERSCAN="Y0URETHERSCANAPIKEYHER3"

4. Generate a new wallet address key pair and fund it from the Chainstack $NETWORK faucet by running in CLI:

npx hardhat run scripts/wallet.js --network $NETWORK  

5. Check wallet balance by running in CLI:

npx hardhat run scripts/balance.js --network $NETWORK  

6. Deploy the NFT minter smart contract from the ABI & BIN files by running in CLI:

npx hardhat run scripts/deploy.js --network $NETWORK  

7. Pin all media files and JSON metadata with Chainstack IPFS Storage by running in CLI:

npx hardhat run scripts/pin.js  

8. Mint an NFT with the metadata from the pinned JSON file by running in CLI:

npx hardhat run scripts/mint.js --network $NETWORK
