NFT Marketplace

I build an NFT Market which name is NFT Sparkz, Firstly, I build this application using React JS, Node JS, Express JS, Mongo DB for user management, Web3, Metamask, TrustWallet, Ethereum, Polygon, Binance, TRON.In this Application we can mint, buy, sell, with auction, royalty fee, deduction fee setting for an asset. I used metamask, trustwallet, connect wallet for this application. I used Polygon, Ethereum, Binance, TRON chain network. And, In this application you can mint an asset in both ERC721(for single asset creation) and ERC1155(for multiple asset creation). The lazy minting process is going on....
