Transferring NFTs sepolia Testnet

This project is part of the Polygon Proof: Proof of Stake by Metacrafters

In this project, we had to create a ERC721 contract to mint and transfer NFTs sepolia testnet. We have used an AI Image generation tool to generate 5 images which will be used as NFTs.  

The images has beed stored on an IPFS, which provides a unique ID called CID for each document. Storing images on an IPFS is more efficient and cost efficient as compared to storing the images on the blockchain, as the gas fee is lower.    

Project Setup

• Clone the repository.
• Run npm i to install all the packages
• Create a .env file to store the private key as PRIVATE_KEY and the contract address as CONTRACT_ADDR

Contract Deployment

• Run npx hardhat compile to compile the solidity files.

• Deploy the contract using the following command  

  npx hardhat run scripts/deploy.js --network sepolia.

• Copy and paste the contract address in the .env file

• Run npx hardhat run scripts/batchMint.js --network sepolia to mint all the NFTs in a single transaction.

• Approve and transfer the NFTs using the following command  

  npx hardhat run scripts/approveDeposit.js --network sepolia
