Confidential Hook

Uniswap v4 Confidential Hook is a privacy-preserving hook implementation for Uniswap v4 that leverages Zero-Knowledge (ZK) Proof to enable confidential trading with compliance, policy, and strategy verification.

This project is built with Noir ZK circuits and Solidity smart contracts, this hook ensures that swap and liquidity operations meet specific criteria without revealing sensitive transaction details on-chain.

Use Cases:

• Institutional Trading: Allows institutions to execute trades while maintaining confidentiality and proving compliance

• Privacy-Preserving DeFi: Enables traders to protect their trading strategies while demonstrating adherence to platform policies

• Regulated Market Access: Facilitates access to DeFi markets with built-in compliance verification

• Confidential Liquidity Provision: Lets liquidity providers add funds while keeping position sizes and strategies private
