Baggr is a DeFi app that turns portfolio management into a swipe-based casual experience. Built on EVM-compatible infrastructure and deployed on the Rise Testnet, it runs Solidity smart contracts to handle token trading with transparency and security. For demonstration purposes, it includes a custom MockMarket contract that follows ERC-20 standards, letting users buy and sell curated token bundles with ETH as the base currency.

The frontend uses RainbowKit for wallet connection and Wagmi + Viem for Web3 interactions, while Hardhat 3 Beta and OpenZeppelin provide the backbone for contract testing and security. Users explore AI-curated bundles through a Tinder-like React interface, each “bag” offering a mix of tokens with algorithmic risk levels and allocations. Smart contracts include preview functions, adjustable pricing, and event logs for full on-chain visibility. GPT-4o powers bundle descriptions and risk assessments based on liquidity and market stability.

Baggr’s edge comes from blending familiar social app UX with blockchain underpinnings, making token investing fun and approachable without sacrificing decentralization. With modular contracts, multi-chain EVM support, and a modern Web3 stack (TypeScript, testing frameworks, and all the essentials), the platform shows how crypto can be packaged into intuitive, consumer-friendly tools while keeping user control at the core.
