Hi, as a senior blockchain engineer, I can build the project successfully very shortly. I have rich experience with the dApp development such as the smart contract, NFT marketplace, and so on in ethereum, binance, Polygon, and so on. So I am familiar with the erc20, erc721, erc1155, etc. Regarding my last NFT marketplace, I built the NFT smart contract using solidity and deployed it using hardhat, Remix, and Truffle. And integrated the smart contract with the front end side using web3, and etherjs. So I can fix the problem successfully in a short period. Let's have a quick chat to discuss anymore. Best Regards.
