I need a seasoned blockchain developer to create a full-featured NFT marketplace that runs on Ethereum, Binance Smart Chain, and Polygon. The core flow is straightforward: mint, list, buy, or sell NFTs across the supported chains without leaving the platform. What I expect: • Smart contracts for minting and trading on each network, written in Solidity (or the most efficient language for that chain) and fully verified. • A web interface where users can: – Create an account via email/password, – Connect their preferred wallet when they’re ready to transact, – Mint new NFTs with custom metadata, – Instantly list or purchase items at fixed price. • Clean, well-documented code plus a brief deployment guide so I can reproduce the setup on my own infrastructure. • Basic admin dashboard to track volumes, fees, and user activity. Please highlight any similar marketplaces you’ve built, your go-to tool stack (e.g., Hardhat, Truffle, [login to view URL], React, Node), and your estimated timeline from smart-contract audit to production launch.

This is a serious build and I am ready for it. I will develop the full multi-chain NFT marketplace across Ethereum, Binance Smart Chain and Polygon, covering verified Solidity smart contracts for minting and trading on each network, a clean web interface with email account creation, wallet connection, NFT minting with custom metadata and fixed price listings, plus an admin dashboard to track volumes, fees and user activity. For the smart contracts, I will write and verify each one through the respective block explorers, with Hardhat handling compilation, testing and deployment so every contract is audit-ready before it touches mainnet. Questions: 1. Do you need royalty logic built into the minting contracts or is this a straightforward fixed price marketplace for now? 2. Which wallet providers should be supported at launch, MetaMask only or others like WalletConnect too? I will share the relevant links in the chat. Once we discuss everything in detail and finalise the requirements, I will be available to start your project right away. Send me a message and we can go over the details. Looking forward to talking through the details. Kamran
