# Concentrated Liquidity Pools (Capricorn CL)

Capricorn’s CLMM follows the same tick math, state layout, and core storage semantics as Uniswap V3. Our contracts are a drop-in replacement at the indexing layer - if your system swaps in the Capricorn Factory and NonFungiblePositionManager addresses, your existing indexer should work without major changes. The pool state, positions, ticks, and liquidity accounting all preserve Uniswap-compatible structures, so most downstream logic can remain the same.

Aggregators can either swap directly through the pool or through swap routers.

#### Example Interfaces

```solidity
interface ICapricornCLPool {
    function swap(
        address recipient,
        bool zeroForOne,
        int256 amountSpecified,
        uint160 sqrtPriceLimitX96,
        bytes calldata data
    ) external returns (int256 amount0, int256 amount1);
}

interface ICapricornCLSwapCallback{
    function capricornCLSwapCallback(
        int256 amount0Delta,
        int256 amount1Delta,
        bytes calldata data
    ) external;
}

interface ICapricornCLMintCallback {
    function capricornCLMintCallback(
        uint256 amount0Owed,
        uint256 amount1Owed,
        bytes calldata data
    ) external;
}

interface ICapricornCLFlashCallback {
    function capricornCLFlashCallback(
        uint256 fee0,
        uint256 fee1,
        bytes calldata data
    ) external;
}
```
