稳健与智能合同中的自动转移

Question

我需要一份聪明的合同，把一定百分比的现金自动送到另一个钱包，

例如，我的公司有一个钱包，而我有另一个业务伙伴，我想立即分享我们公司的利润，当涉及到公司的钱包时，我和我的合作伙伴在技术上是否有可能订立一份明智的合同来进行这种转让!？

谢谢

实现这一点的唯一方法是通过智能契约，不可能直接在钱包中执行此规则。

如何在可靠的情况下这样做的一个例子是使用一个智能契约，它看起来可能如下所示：

pragma solidity 0.8.9;

interface IERC20 {
function balanceOf(address who) external view returns (uint256);
function transfer(address to, uint256 value) external returns (bool);
function allowance(address owner, address spender) external view returns (uint256);
function transferFrom(address from, address to, uint256 value) external returns (bool);
function approve(address spender, uint256 value) external returns (bool);
event Transfer(address indexed from, address indexed to, uint256 value);
event Approval(address indexed owner, address indexed spender, uint256 value);
}

contract MyVault {

address public yourWallet;
address public partnerWallet;
uint256 public partnerFee;

constructor(address _yourWallet, address _partnerWallet, uint256 _partnerFee) {
    yourWallet = _yourWallet;
    partnerWallet = _partnerWallet;
    partnerFee = _partnerFee;
}

function applyFee(address _coin, uint256 _quantity) public returns(bool) {
    IERC20 coinInstance = IERC20(_coin);
    require(coinInstance.allowance(msg.sender,address(this)) >= _quantity, "MyVault: not approved" );
    require(coinInstance.transferFrom(msg.sender, address(this), _quantity), "MyVault: transfer from failed");
    uint256 partnerAmount = calculateFee(_quantity);
    coinInstance.transfer(partnerWallet, partnerAmount);
    coinInstance.transfer(yourWallet, _quantity - partnerAmount);
    return true;
}

function calculateFee(uint _value) public view returns(uint256) {
       return (partnerFee * _value) / 100;
   }

}
