This project contains a smart contract template for NFT collection. Besides the standard ERC721 interface powered by openzeppelin, we added a few features:
Only contract owner can call this function. Call this function with an array of address and each of them will receive one new minted NFT.
Anyone who have the valid signature can mint NFTs by paying enough crypto. The signature is generated by the signer address defined in EIP712Whitelist.sol. Contract owner can use toggleSaleStatus() to enable/disable private mint.
NFT owner can burn the NFT to redeem a service like an eCoupon. After the NFT is burnt, the tokenId is added to a redeemed arrary and emit an event. To provide the service after the redemption, you will need an offchain server listening to the Redeem event.
