描述

MetaCard YieldFlow is a next-generation DeFi dashboard that brings the simplicity and familiarity of MetaMask to a powerful, card-linked experience. Users can deposit, spend, and withdraw USDC with a virtual card, build on-chain reputation, and unlock exclusive NFT badge rewards—all in a beautiful, modern UI.

Key Features:

MetaCard Virtual Card: Manage USDC with a MetaMask-style card UI.

On-Chain Reputation: Every transaction builds your DeFi rep. Hit milestones to unlock NFT badges and rise through card tiers.

NFT Badge Rewards: Mint exclusive, non-transferable NFT badges as you level up your reputation.

Cross-Chain USDC: Instantly bridge USDC across supported chains with LI.FI integration.

Real-Time Automation: Get instant notifications and automate actions with n8n workflow integration.

Modern, Responsive UI: Beautiful, accessible, and mobile-friendly.

Secure, Modular Smart Contracts: Written in Solidity, leveraging OpenZeppelin standards.

Hackathon Alignment:

MetaCard YieldFlow addresses DeFi-Driven Card Utilities, Identity & On-Chain Reputation, Multichain USDC Payment System, Smart Agents & Liquidity Automation, and Composable Cross-Chain Applications. It leverages MetaMask SDK, LI.FI, and USDC, and is ready for Circle Wallets integration.

本次黑客松进展

> During the hackathon, we designed, developed, and deployed the core features of MetaCard YieldFlow from scratch. This includes: > - Building a fully functional frontend dashboard with wallet connection, card-linked DeFi actions (deposit, spend, withdraw), and real-time on-chain reputation tracking. > - Implementing smart contracts for yield management and reputation NFTs. > - Integrating automation via n8n for notifications and workflow triggers. > - Adding cross-chain USDC bridging with LI.FI. > - Creating a modern, responsive UI/UX inspired by MetaMask Card. > - Writing comprehensive documentation and a demo-ready pitch. > - Developing backend integration for Circle card top-ups, enabling users to fund their MetaCard directly with fiat. However, Circle is currently not granting new access to their payments/cards API for new customers. If this feature were available, it would have enabled us to scale up the product and offer seamless fiat-to-DeFi onboarding. > > All features were built, tested, and refined during the hackathon period, with a strong focus on user experience, composability, and hackathon track requirements
