FidelHook

FIDELHOOK is a loyalty-based fee structure for DeFi that rewards users with progressively lower trading fees based on their engagement and streak history on decentralized exchanges. By tracking user interactions and activity duration, FIDELHOOK dynamically calculates a loyalty score that determines fee tiers, offering the lowest trading costs for long-term, active users.

How It Works: FIDELHOOK measures loyalty through two factors: transaction volume and consecutive activity streaks. As users trade more and maintain streaks, they achieve higher loyalty tiers, unlocking greater fee discounts and exclusive benefits.

Key Features:

• Tiered Discounts: Higher tiers offer lower fees.
• Streak Rewards: Consistent activity boosts loyalty score.
• Dynamic Fees: Real-time fee adjustments based on loyalty.
• Exclusive Perks: Benefits for top-tier users, including early access and support.

FIDELHOOK fosters a more engaging DeFi ecosystem by rewarding loyalty, making trading more affordable and accessible for committed users.

FidelHook is a loyalty incentive protocol architected on the Uniswap
v4 Hook framework. We leverage v4’s custom hook capabilities to
transform user trading continuity—or "streaks"—into real-time,
on-chain fee discounts. The project was built using Solidity and
Foundry for the smart contracts, while the frontend was developed with Next.js 15 and Tailwind CSS to create an industrial,
Cyber-Utilitarian terminal interface.

Throughout the development process, we conducted deep research into
the Uniswap v4 beforeSwap and afterSwap lifecycles to implement our
dynamic fee calculation engine. For the current demonstration, we
utilized a high-fidelity hook simulation environment to accurately
showcase the 24-hour streak logic and complex on-chain state
transitions. In production, this architecture is designed to deploy
directly to the Uniswap v4 PoolManager, integrating with real
liquidity pools via Alchemy’s Sepolia nodes to provide a fully
decentralized and personalized liquidity incentive layer.
