NFT Marketplace & Trading dApp
Full-stack NFT marketplace with on-chain trading and a fiat on-ramp.
Overview
A decentralized marketplace where users connect wallets to browse and trade NFTs, backed by Solidity smart contracts and a Node/Express service layer.
Rather than a contract-only demo, it combines Web3 wallet flows with a traditional backend for off-chain data, scheduled jobs and a Stripe fiat on-ramp, a complete product.
What I built
- Solidity contracts with Hardhat Ignition deployments.
- Wallet flows and trading UI with wagmi, viem, RainbowKit and MetaMask SDK.
- Node/Express + Prisma backend with Stripe payments and scheduled jobs (node-cron).
- Market charts with lightweight-charts and a Telegram bot integration.
