稳健和智能合约中的自动转账

Question

我需要一个智能合约，将一定百分比的传入代币自动发送到另一个钱包

例如，我的公司有一个钱包，我有另一个商业伙伴当涉及到公司的钱包时，我想在我和我的合伙人之间立即分享我们公司的利润从技术上讲，制作一份智能合约来完成这笔交易是可能的吗！？

感谢

实现这一点的唯一方法是通过智能合约，不可能直接在钱包中执行此规则。

如何在solidity中实现这一点的一个例子是使用智能合约，它可能看起来像这样：

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;
}
}
