Uniswap V4 Hooks Implementation Example

This is for the explanation of the flaunch and rehypothecasion.

This repository serves as a practical demonstration of Uniswap V4 hooks implementation It showcases how to build aave integrations

Uniswap V4 Hooks Showcase

The core focus of this project is to demonstrate the power and flexibility of Uniswap V4 hooks. The FusedHooks contract illustrates:

• Hook implementation with multiple hook points (BEFORE_INITIALIZE, BEFORE_ADD_LIQUIDITY, BEFORE_SWAP)
• Integration with external protocols (Aave V3) through a hook interface
• Custom pool behavior with hooks that modify the standard AMM experience
• CREATE2 deployment pattern for hooks with correct flags

Overview

FusedETH demonstrates a yield-generating ETH wrapper that leverages Uniswap V4 hooks and Aave V3. Key features include:

1. Deposit ETH to receive fusedETH tokens (1:1 ratio)
2. Underlying ETH is deployed to Aave V3 to generate yield
3. Custom hook logic ensures seamless swapping between ETH and fusedETH
4. Yield harvesting mechanics with distribution to designated receivers

Key Components

• FusedHooks: The central showcase of this repo - demonstrates Uniswap V4 hook implementation
• FusedETH: ERC20 token that wraps ETH with yield capabilities
• AaveV3Strategy: Strategy for yield generation through Aave
• AaveV3WethGateway: Custom gateway for Aave interaction

Hook Implementation Details

The FusedHooks contract demonstrates:

• Proper hook initialization and flag configuration
• Complex hook logic across multiple hook points
• State management via hooks
• Integration with external protocols in hook callbacks

Development and Testing

The project includes comprehensive integration tests that show the hooks in action:
