DEX Precompiles

Uniswap v4-style native DEX operations

DEX Precompiles

Native EVM precompiles implementing Uniswap v4-style decentralized exchange with singleton architecture.

Address Range

DEX precompiles occupy addresses 0x0400 through 0x0403.

Performance Benchmarks (Apple M1 Max)

Operation	Latency	Throughput
Swap	2.26μs	443K ops/sec
ModifyLiquidity	2.87μs	348K ops/sec
PoolKeyID	439ns	2.7M ops/sec

Usage

import {IPoolManager} from "@luxfi/precompile/dex/IPoolManager.sol";

contract SwapExample {
    IPoolManager constant POOL = IPoolManager(0x0400);

    function swap(
        PoolKey calldata key,
        IPoolManager.SwapParams calldata params
    ) external returns (BalanceDelta) {
        return POOL.swap(key, params, "");
    }
}

Architecture

The DEX precompile implements:

Singleton Architecture - All pools in single contract
Flash Accounting - Token transfers netted at transaction end
Hooks System - Modular contracts for custom pool logic
Native LUX Support - No wrapping required

Lux Standard Contracts - Pure Solidity AMM implementations
PoolManager LP - Detailed pool manager specification
