Description
Automate Your DeFi — Smarter, Safer, Seamless
🧠 Introduction & Problem Statement
In the rapidly evolving world of decentralized finance (DeFi), managing cross-chain assets, optimizing yield, and minimizing gas fees has become increasingly complex for both novice and experienced users. Manually switching between protocols, networks, and dApps is not only time-consuming but also exposes users to unnecessary risk and inefficiency.
Despite the emergence of MetaMask Cards, there has been no unified automation layer tailored to it — until now.
💡 What We Built
MetaMask Card AutoFlow is a fully-functional Web3-based DeFi automation dashboard built with Next.js, Web3.js, and smart contract integrations. It acts as a non-custodial automation platform that empowers MetaMask Card users to:
🚀 Automate yield farming, bridging, and asset allocation
🔄 Bridge assets automatically between Ethereum, Polygon, Arbitrum, and Linea
📊 Track multi-chain USDC balances in real time
⚙️ Set custom automation rules based on user-defined risk and earning goals
🛡️ Maintain complete control of funds (no central wallet custody)
Everything runs on-chain with audited smart contracts and requires explicit wallet permission before execution — ensuring security, transparency, and user sovereignty.
🔧 Core Features & Implementation
Live Portfolio Dashboard
→ Real-time visibility into total USDC portfolio, daily yield, chain-wise distribution, and automation performance.Multi-Chain Tracking
→ Users can monitor balances across Ethereum, Polygon, Arbitrum, and Linea — all from one place.Auto-Bridging Engine
→ Built logic to detect optimal gas timing and yield discrepancies, triggering automatic cross-chain bridging when beneficial.Yield Optimization Module
→ Seamlessly integrates with Aave, Yearn, Curve for the highest APYs, configured via user risk preferences.Smart Automation Rules
→ Users can set automation conditions like:“If Arbitrum yield > Ethereum yield by 2%, bridge and stake”
“Auto-withdraw from protocols during high volatility”
Security by Design
→ Every action requires MetaMask confirmation, uses open-source code, and runs on audited smart contracts.
📈 Value Proposition
DeFi made effortless — No more jumping between protocols or worrying about timing the market.
Non-custodial by default — No platform risk. User funds remain in their wallet.
Truly automated passive income — Users “set it and forget it.”
Made for MetaMask Card — Specifically designed to enhance card-based DeFi usabilit
Progress During Hackathon
During the hackathon, we successfully designed and developed MetaMask Card AutoFlow, a complete DeFi automation platform tailored for MetaMask Card users. We built a fully functional dashboard using Next.js and integrated it with Web3.js to enable real-time portfolio tracking, cross-chain USDC balance monitoring, and smart automation tools. Key features like **auto-bridging**, **yield optimization**, and a **custom rules engine** were implemented to allow users to set and manage DeFi strategies across Ethereum, Polygon, Arbitrum, and Linea. Our smart contracts ensure non-custodial, secure automation, and we focused on creating a smooth UX with a live performance overview, making DeFi effortless and intelligent.
Tech Stack
Fundraising Status
Currently, MetaMask Card AutoFlow is in the post-MVP phase with a fully functional prototype, and we are actively exploring fundraising opportunities to scale development, enhance security audits, and onboard early adopters. We aim to raise a pre-seed round to support smart contract optimization, multi-chain expansion, and community growth initiatives. Our monetization strategy includes premium automation modules, API access for DeFi platforms, and partnerships with MetaMask ecosystem partners. With a strong product-market fit in the DeFi automation space and growing traction, we’re looking for investors who believe in making DeFi simpler, smarter, and safer for all.
