solidity 员工薪酬案例

以下是一个使用 Solidity 编写的员工薪酬合约的案例：

pragma solidity ^0.8.0;

contract EmployeeSalaryContract {
    address public owner;
    address public employee;
    uint public salary;
    uint public lastPayday;

    constructor(address _employee, uint _salary) {
        owner = msg.sender;
        employee = _employee;
        salary = _salary * 1 ether; // 将薪资转换为以 wei 为单位的整数
        lastPayday = block.timestamp;
    }

    // 发放薪资
    function paySalary() public {
        require(msg.sender == owner, "Only owner can pay salary.");
        uint nextPayday = lastPayday + 30 days;
        require(nextPayday < block.timestamp, "It's not time to pay salary yet.");
        uint payments = (block.timestamp - lastPayday) / 30 days;
        uint amount = payments * salary;
        lastPayday = nextPayday;
        payable(employee).transfer(amount);
    }

    // 修改员工地址
    function changeEmployee(address newEmployee) public {
        require(msg.sender == owner, "Only owner can change employee.");
        employee = newEmployee;
    }

    // 修改员工薪资
    function changeSalary(uint newSalary) public {
        require(msg.sender == owner, "Only owner can change salary.");
        salary = newSalary * 1 ether;
    }

    // 查询合约余额
    function getBalance() public view returns(uint) {
        return address(this).balance;
    }
}

该合约包含了发放薪资、修改员工地址、修改员工薪资和查询合约余额等功能。在合约创建时需要指定员工地址和薪资，薪资会以以 wei 为单位的整数存储，每月发放一次，发放前需要检查是否到了发薪日，并计算应发的薪资金额。
