自动流动性( Auto ) Bep20联系人

Question

我需要一个自动的流动性系统来实现货币的崛起和未来，我该如何做到这一点？(我使用了现成的代码，因为我是刚接触到稳健性的)

 pragma solidity ^0.8.2;

contract Token {
    mapping(address => uint) public balances;
    mapping(address => mapping(address => uint)) public allowance;
    uint public totalSupply = 10000 * 10 ** 18;
    string public name = "My Token";
    string public symbol = "TKN";
    uint public decimals = 18;
    
    event Transfer(address indexed from, address indexed to, uint value);
    event Approval(address indexed owner, address indexed spender, uint value);
    
    constructor() {
        balances[msg.sender] = totalSupply;
    }
    
    function balanceOf(address owner) public returns(uint) {
        return balances[owner];
    }
    
    function transfer(address to, uint value) public returns(bool) {
        require(balanceOf(msg.sender) >= value, 'balance too low');
        balances[to] += value;
        balances[msg.sender] -= value;
       emit Transfer(msg.sender, to, value);
        return true;
    }
    
    function transferFrom(address from, address to, uint value) public returns(bool) {
        require(balanceOf(from) >= value, 'balance too low');
        require(allowance[from][msg.sender] >= value, 'allowance too low');
        balances[to] += value;
        balances[from] -= value;
        emit Transfer(from, to, value);
        return true;   
    }
    
    function approve(address spender, uint value) public returns (bool) {
        allowance[msg.sender][spender] = value;
        emit Approval(msg.sender, spender, value);
        return true;   
    }
}

首先，不要使用代码，这是你不明白的。外面的骗局太多了。

我建议你找个可靠的开发商，让他来写合同。即使您发现或设计的契约有效，也很有可能存在漏洞，攻击者将利用这些漏洞。

说到这里，你发布的代码只是一个象征，而不是流动性协议。如果您需要一个令牌，我会建议您查看ERC20，并使用Uniswap的流动性供应。
