This program consists of a simple Smart contract and corresponding scripts, for minting Non-Fungible Tokens (NFTs) in batch. An extended version of ERC721 standard contract is being used here, namely ERC721A, a brainchild of the Azuki Team. Using this project, one can batchmint NFTs, reducing transaction costs on Ethereum, and can tranfer those NFTs to the Polygon network using a FxERC721RootTunnel.

• Place your wallet address and private key into a .env file as shown in .env.sample.
• Download or copy ABI from FxERC721RootTunnel Contract on Goerli and place it in the assets directory as fxRootContractABI.json.

    npm install

• While the scripts are divided into separate commands, we can still run npm start to run first 4 commands (viz.: compile, deploy, mint and transfer) merged into one.

• To compile:

    npm run compile
  

• To deploy:

    npm run deploy
  

• To mint:

    npm run mint
  

• To transfer:

    npm run transfer
  

• To check balance:

    npm run balance
  

• Deployment, minting and transfer are being done on the Goerli testnet.
• After transfer, we need to wait for around half an hour for the transactions to show up in the Polygon network.
• When the transactions are available on the Polygon network, we can copy the contract address from there and place it in contractAddress variable inside 4_checkbalance.js script, before running it.
