An NFT drop I created as part of @_buildspace's Ethereum NFT project. I have extended the my application & smart contracts to allow additional features below (while they may not be 100% gas optimized):
See RandomWordsERC721A.sol for smart contract
Additional features:
- Front-end
- MetaMask prompt to switch to Rinkeby network
- Buttons to adjust quantity for batch minting
- Toast message linking transaction
- Solidity:
- Batch minting
- Gas optimzation in storing tokens on-chain
