Blockchain E-Commerce Platform Development

I want to launch a new e-commerce platform that runs natively on blockchain technology, giving every customer provable ownership of each transaction and me, as the store owner, iron-clad control over inventory, payments and dispute resolution through smart contracts.

The build needs to cover the full stack: a responsive web storefront, the back-office admin dashboard and the on-chain layer that processes orders, handles payments in crypto and records delivery milestones immutably. I’m open on whether we use Ethereum, BNB Smart Chain, Solana or another network; what matters most is a secure, gas-efficient and future-proof solution. Bring your own recommendations and explain why they fit.

Deliverables
• Production-ready smart contracts with clear comments and unit tests
• Modern web UI/UX (React, Next.js or similar) wired to the contracts via Web3 / Ethers.js
• Crypto and fiat payment flows, plus wallet connect for MetaMask and mobile wallets
• Admin panel to manage products, orders, refunds and on-chain analytics
• Deployment scripts, basic CI/CD pipeline and concise documentation so I can run updates without hand-holding

Acceptance criteria
1. All core user actions (add to cart, checkout, refund) trigger a verifiable on-chain event.
2. Front end passes Lighthouse performance audits (>90) and works across modern browsers and mobile.
3. Contract test suite covers at least 90 % of logic branches with Hardhat or Truffle.
4. A demo on a public testnet proves end-to-end flow before mainnet launch.

Tell me your preferred chain, estimated timeline and any past links that show a live blockchain commerce build.
