This is NFT minting Dapp and I have built smart contract, web3 integration, minting page.
It doesn't include staking logic so smart contract is not so complex.
It has og, wl, public mint functions and merkle tree is used for white list and og check.
All metadatas deployed on pinata and I genereated it using simple metadata generating JS code.
Minting page support Metamask, Wallet connect extensions but I didn't test wallet connection because of QRcode scan.
Frontend was built using React.js and I used etherjs for web3.
