This project introduces a token buyback mechanism for Uniswap v4 using a specialized hook. The hook is designed to allocate a portion of the fees collected from token swaps and liquidity withdrawals for the purpose of automatically buying back a specific token. This innovative approach aims to enhance liquidity and contribute to the stabilization of the token's value.

• Fee Allocation: A predefined percentage of the fees from swaps and withdrawals is earmarked for the buyback.
• Automated Buyback Process: The accumulated fees are used to automatically purchase the specified token at regular intervals or under certain market conditions.
• Market Sensitivity: The mechanism is designed to respond dynamically to market fluctuations, optimizing buyback timing and volumes.

• The hook integrates seamlessly with the existing Uniswap v4 framework, complying with its operational and security standards.
• It enhances the Uniswap v4 ecosystem by adding a new layer of functionality beneficial to token stability.

• Liquidity Enhancement: By reinjecting capital into the token market, the mechanism bolsters liquidity.
• Price Stabilization: Regular buybacks can mitigate volatility, contributing to a more stable token valuation.

• Token Value Support: Supports the market value of the token by reducing supply and potentially increasing demand.
• Confidence in Liquidity: Increases confidence among liquidity providers and traders in the token's market.
• Enhanced LP Rewards: Potentially increases the value of liquidity provider rewards.

Scripts for deploying the token buyback hook on the following testnets will be provided:

• Polygon zkEVM
• Optimism Testnet
• Arbitrum Testnet
