NiceReview NFT trophies

Requirements

• node 16
• hardhat
• An Alchemy account
• A Pinata account

Project structure

• contracts folder contains the Solidity contract used to create the NFTs.
• tasks contains the deploy.js and mint.js scripts used to deploy the contract and invoke the contract's safeMint method during the NFT creation.
• static contains the images and json_metadata used to create the NFTs

Running the project

Locally

First, start a local "Ethereum node" using hardhat.

Step 1

npx hardhat node

The command above will output some local test accounts which will be used later during the NFT creation.

Started HTTP and WebSocket JSON-RPC server at http://127.0.0.1:8545/

Accounts
========

WARNING: These accounts, and their private keys, are publicly known.
Any funds sent to them on Mainnet or any other live network WILL BE LOST.

Account #0: 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 (10000 ETH)
Private Key: 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Account #1: 0x70997970C51812dc3A010C7d01b50e0d17dc79C8 (10000 ETH)
Private Key: 0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d

Step 2

In another tab, deploy the NFT contract to the local node.

npx hardhat deploy --network localhost

The command above will generate an output similar to:

Creating the contract factory for NiceReviewTrophyNFT 🏃
Deploying the NiceReviewTrophyNFT contract 🚀
Contract successfully deploy to blockchain at 0x5FbDB2315678afecb367f032d93F642f64180aa3 🎉

The address 0x5FbDB2315678afecb367f032d93F642f64180aa3 represents the contract's address in the local node, keep it for the next command.

Step 4

Finally, create the NFT running the command below. Provide one of the test account's addresses to the --to-address argument (from the first step). Use QmTNi2TeeDkL1r3JPVNWnJAGxUFuQUFVmGpWPE2T5G4Tz3 as --ipfs-cid argument for now.

You can use Pinata to deploy your own image and JSON metadata, and then use your own IPFS CID here

npx hardhat mint \
--contract-address 0x5FbDB2315678afecb367f032d93F642f64180aa3 \
--to-address 0x70997970C51812dc3A010C7d01b50e0d17dc79C8 \
--ipfs-cid QmTNi2TeeDkL1r3JPVNWnJAGxUFuQUFVmGpWPE2T5G4Tz3 \
--network localhost

Ethereum goerli testnet

⚠️ Never commit your private key, people will certainly steal your Ethereum funds using that key

First, create a .env file containing:

GOERLI_ALCHEMY_NODE_URL_WITH_API_KEY="https://eth-goerli.g.alchemy.com/v2/<YOUR_ALCHEMY_API_KEY>"
GOERLI_SIGNER_PRIVATE_KEY="<YOUR WALLET PRIVATE KEY>"

Then, replace the --network localhost by --network goerli in the commands shown in the section above to deploy your contract and create your NFTs in the Goerli testnet.

Ethereum mainnet

⚠️ Never commit your private key, people will certainly steal your Ethereum funds using that key

First, create a .env file containing:

ALCHEMY_NODE_URL_WITH_API_KEY="https://eth-mainnet.g.alchemy.com/v2/<YOUR_ALCHEMY_API_KEY>"
SIGNER_PRIVATE_KEY="<YOUR WALLET PRIVATE KEY>"

Then, replace the --network localhost by --network mainnet in the commands shown in the section above to deploy your contract and create your NFTs in the Ethereum's mainnet.
