solidity合约创建合约

参考uniswap的Factory合约创建交易对

pragma solidity ^0.8.1;

contract Pair{
    
    
    address public factory;
    address public token0;
    address public token1;
    constructor(address _token0, address _token1) payable{
    
    
        token0 = _token0;
        token1 = _token1;
        factory = msg.sender;
    }
}

contract Factory{
    
    
// 存储创建的子合约地址
    Pair[] public allPairs;
    // 创建pair
    function createPair(address _token0, address _token1) public{
    
    
        Pair pair = new Pair(_token0, _token1);
        allPairs.push(pair);
    }
    // 支付 创建pair并
    function createPairV(address _token0, address _token1) public payable{
    
    
        Pair pair = (new Pair){
    
    value: msg.value}(_token0, _token1);
        allPairs.push(pair);
    }
}
