NFT Warranty Platform Development

I’m building an NFT-powered warranty platform that turns each purchased product into a transferable digital warranty token. The core flows I must ship are registering warranties at point of sale, transferring ownership when a product changes hands, and letting the current holder claim warranty benefits in a single click. MetaMask and WalletConnect need to work seamlessly throughout these actions.

The stack is already defined: React + Next.js for the UI, Node.js for the API layer, Solidity for the NFT contracts, and Web3.js/ethers.js for wallet and blockchain calls. I’ll share preliminary wireframes, a Solidity draft, and a database schema; your job is to turn them into production-ready code that passes automated tests and a security audit.

Key expectations
• Build a responsive Next.js front end that connects to MetaMask and WalletConnect without page reloads.
• Write or refine Solidity contracts for minting, ownership transfer, and warranty-claim validation, then deploy to testnet and mainnet.
• Expose REST endpoints (and, where helpful, GraphQL) in Node.js to bridge off-chain data such as serial numbers and customer details.
• Persist data in a relational or document database of your choice and document the schema clearly.
• Deliver clean, well-commented code, unit tests, and concise setup instructions so any new contributor can get the stack running in minutes.

I’m flexible on full-time or part-time arrangements; steady, reliable communication and demonstrable experience with NFTs, wallets, and production smart contracts are what matter most. If you’ve taken a Web3 product from idea to launch before, I’d love to see it.
