Uniswap V4-native liquidity management platform automating LP strategies.

2025

Objective

Build a Uniswap V4-native liquidity management platform (comparable to Revert Finance) that automates LP strategies.

Technical Challenges

  • 1.Uniswap V4's new hooks architecture required fundamentally different patterns.
  • 2.Managing concentrated liquidity positions demands precise rebalancing logic.
  • 3.Real-time position monitoring with reliable trigger mechanisms.

Outcomes & Impact

  • Delivered first-to-market V4-native LP automation platform.
  • Reduced LP management overhead by 90% through automated rebalancing.
  • Achieved 15-25% improved capital efficiency for LPs.

Implementation

liquifi.sol
1// Uniswap V4 Hook: Auto-Compounding
2function afterSwap(address, PoolKey calldata key, IPoolManager.SwapParams calldata, BalanceDelta, bytes calldata) 
3    external override returns (bytes4) 
4{
5    // Capture swap fees
6    uint256 fees = poolManager.getProtocolFees(key);
7    
8    if (fees > COMPOUND_THRESHOLD) {
9        // Re-add as liquidity
10        _addLiquidity(key, fees);
11    }
12    return IHooks.afterSwap.selector;
