Descripción
The MetaMask Card Hackathon is designed to inspire developers, designers, and innovators to build innovative applications that integrate the MetaMask Card, LI.FI, and USDC. This event aims to bridge the gap between traditional finance and decentralised ecosystems, promoting solutions that enhance user experiences, financial accessibility, and on-chain utility.
Select participating developers will have the opportunity to record their project demo and receive a professionally produced video at the Circle Dev Summit in Cannes. To be considered, please submit a preliminary version of your project by June 24th. Circle and MetaMask will help amplify your video and project after the event.
Go to the Prize & Judge session for more details
Build smart agents and automation systems (onchain bots, workflows, or smart contracts) that handle spending, rebalancing, and real-time liquidity management across chains. Ideal solutions optimize rewards, credit usage, or card top-ups with minimal user input.
Create DeFi tools that boost the utility of card-linked assets. Think allocation, protocol routing, or trustless credit lines. Explore how composable DeFi protocols can power borrowing, repayments, or staking tied directly to card activity.
Use onchain identity, KYC, and behavioral data to power loyalty programs, access tiers, or exclusive perks. Explore integrations that transform user actions into reputation or rewards, bridging the gap between privacy and personalization.
Build an application that enables multichain USDC payments and payouts, remittances, treasury rebalancing, swaps, or seamless USDC purchases.
Build seamless, composable apps that span multiple chains, abstract away complexity, and empower users to move value, data, or identity across ecosystems without friction.
Bonus rewards available for:
Projects that use the MetaMask SDK or MetaMask Delegation Toolkit (DTK) ($2,000)
Projects that use Circle Wallets ($2,000)
Projects that use the LI.FI SDK (through Circle CCTP V2) ($2,000)
Projects must explore real-world use cases of the MetaMask Card (rewards, identity, DeFi credit, etc.).
Projects must use USDC for stablecoin payments and payouts
Projects must use LI.FI SDK/API/Widget (Track 4 only)
A README with project details and a short recorded demo video is required.
Live hosted demo or working prototype.

Build seamless, composable apps that span multiple chains, abstract away complexity, and empower users to move value, data, or identity across ecosystems without friction.
We're looking for projects that demonstrate how a user can:
Tap into cross-chain assets to access optimal (lowest-cost) credit lines
Unlock value from idle assets by putting them to productive use
Automatically use that value to repay credit over time
Deliver the result as a spendable balance on the MetaMask Card wallet (Linea or any other supported network)

Ideas
Potential Concepts Leveraging the Card as Proof of Identity
Cashback Rewards: Implement a system similar to app.coinback.fun, where users receive cashback rewards for using the card. This could incentivise spending and promote card adoption.
Tiered Rewards: Instead of a 1:1 cashback model, offer a tiered rewards system based on monthly spending. For example, users who spend over a certain threshold could unlock exclusive prizes or benefits.
Event Tickets & Discounts: Partner with event organizers and retailers to offer discounted tickets or exclusive in-store discounts to cardholders. This could create unique experiences and drive spending.
Proof of KYC/Humanity/Spend: Explore using the card as a form of digital identity verification. This could streamline KYC processes and enable access to specific services or platforms.
On-Chain Metrics & Card Integration
Staking & Locking: Incentivize users to lock or stake a specific cryptocurrency to unlock additional card benefits or rewards. This could encourage long-term holding and support the token's ecosystem.
Combined On-Chain/Off-Chain Rewards: Create a system that combines on-chain metrics (like staking) with off-chain spending to offer unique rewards or benefits. This could bridge the gap between on-chain and off-chain activity.
Yield Optimization & Rebalancing Strategies
Automated Rebalancing: Develop tools or features that automatically rebalance users' stablecoin or WETH holdings across different lending pools to maximize yield. This could simplify yield optimisation and attract users looking for passive income opportunities.
Credit Line Management & Optimisation
Automated Credit Line Management: Explore creating an agent or tool that automates the process of taking out and repaying credit lines, optimizing for yield and minimizing costs. This could simplify credit management and attract users who want to leverage their assets.
Yield-Based Credit Repayment: Develop strategies that use yield generated from DeFi protocols to automatically repay credit lines, reducing interest costs and maximizing capital efficiency.
Automated Financial Management Agent
Personalized Financial Assistant: Create an AI-powered agent that manages all aspects of a user's card and DeFi interactions, from yield optimization to credit line management. This could provide a comprehensive financial management solution and attract users who want to outsource their financial decision-making.
Customizable Agent Settings: Allow users to customize the agent's behavior and risk tolerance to align with their individual financial goals and prefer.

Crypto Checkout
Universal Checkout Experience: Build a crypto-native checkout product that enables seamless payments across any chain or token, powered by the LI.FI widget. Users can pay with any asset on any chain, and merchants receive USDC on their preferred chain—no bridging or swapping knowledge required.
Plug-and-Play Integration: Offer an embeddable widget or SDK that can be integrated into e-commerce sites, NFT platforms, or dApps. Focus on speed, UX, and reliability, with built-in LI.FI routing, fee customization, and merchant dashboards for tracking payments.
