A new e-commerce platform called SmartShoppie has deployed blockchain technology to create crowdfunding pools with automated refund systems and NFT-based rewards. The platform, built using the Yellow SDK development toolkit, allows users to pool funds for expensive products through smart contracts deployed on the Ethereum Sepolia testnet.
What to Know:
- SmartShoppie enables group purchases through blockchain crowdfunding pools with automatic refunds if funding goals are not met
- The platform integrates NFT rewards and workshop access for successful participants using smart contract technology
- Development utilized Yellow SDK, a chain-agnostic Web3 development toolkit that simplifies blockchain application creation
The system operates through user-created pools with specific funding targets and deadlines. When a user like Alice creates a pool for a 3D printer with a $10,000 goal and 30-day deadline, participants such as Bob can contribute funds that are tracked through the platform's smart contract system. If the pool reaches its target, funds transfer to the supplier and participants receive their products plus NFT-based workshop access. Failed pools trigger automatic refunds to all contributors.
The platform's smart contract architecture tracks participation through a "hasParticipated" mapping system. It exposes a participate function that registers users and emits participation events for off-chain notifications. Deployment occurred on a local Hardhat network through standard blockchain development commands.
SmartShoppie's frontend employs React and Vite to create a modern e-commerce interface. The product display includes real-time discount timers and live pricing updates. WebSocket integration on port 10000 sends purchase data to backend servers while an authentication modal collects wallet addresses for blockchain transactions.
Blockchain integration relies on wagmi and viem libraries for Ethereum connectivity. The useAccount function automatically detects connected wallet addresses while useWriteContract handles on-chain transactions. Wallet information and product details flow through WebSocket connections for backend logging purposes.
The development team configured wagmi version 2 with React standards using Sepolia testnet and HTTP transport providers. Additional libraries include @tanstack/react-query for state management, Vite for frontend development, and Hardhat for Ethereum development and deployment.
Yellow SDK, the underlying development framework, serves as a high-performance, chain-agnostic toolkit designed to bridge traditional Web2 and emerging Web3 development practices.
The toolkit offers multi-chain compatibility out of the box, allowing applications to work across different blockchain networks without requiring separate implementations for each. Rather than requiring developers to become blockchain experts, it provides a single integration layer that handles all the chain-specific logic behind the scenes.
The SDK addresses common Web3 development challenges including complex wallet integrations, gas optimization, and user experience difficulties. It enables off-chain execution for real-time interactions, addressing one of the biggest pain points in Web3 user experience: waiting for transactions to confirm on-chain.
Closing Thoughts
SmartShoppie represents an emerging trend of e-commerce platforms incorporating blockchain technology for group purchasing and automated financial management. The platform's use of Yellow SDK demonstrates how modern development tools are making Web3 application creation more accessible to traditional developers. The combination of smart contracts, NFT rewards, and automated refund systems offers users a new model for collaborative purchasing while maintaining the security and transparency benefits of blockchain technology.
