这个代码可以部署到你在做交互的测试链上增加你账号的权重 // SPDX-License-Identifier: MIT pragma solidity ^0.8.0; contract ZKSbaby { string public name = "ZKSbaby"; //名字 string public symbol = "ZKS"; //简写 uint256 public totalSupply = 100000000 * 10**18; // 100 million tokens with 18 decimal places uint8 public decimals = 18; address public marketingWallet = 0x000000000000000000000000000000000000dEaD; //营销钱包修改你自己的 uint256 public marketingTax = 2; //税 mapping(address => uint256) private _balances; mapping(address => mapping(address => uint256)) private _allowances; event Transfer(address indexed from, address indexed to, uint256 value); event Approval(address indexed owner, address indexed spender, uint256 value); constructor() { _balances[msg.sender] = totalSupply; } function balanceOf(address account) public view returns (uint256) { return _balances[account]; } function transfer(address recipient, uint256 amount) public returns (bool) { _transfer(msg.sender, recipient, amount); return true; } function allowance(address owner, address spender) public view returns (uint256) { return _allowances[owner][spender]; } function approve(address spender, uint256 amount) public returns (bool) { _approve(msg.sender, spender, amount); return true; } function transferFrom(address sender, address recipient, uint256 amount) public returns (bool) { _transfer(sender, recipient, amount); _approve(sender, msg.sender, _allowances[sender][msg.sender] - amount); return true; } function _transfer(address sender, address recipient, uint256 amount) private { require(sender != address(0), "ZKSbaby: transfer from the zero address"); require(recipient != address(0), "ZKSbaby: transfer to the zero address"); uint256 marketingFee = amount * marketingTax / 100; _balances[sender] -= amount; _balances[recipient] += amount - marketingFee; _balances[marketingWallet] += marketingFee; emit Transfer(sender, recipient, amount - marketingFee); } function _approve(address owner, address spender, uint256 amount) private { require(owner != address(0), "ZKSbaby: approve from the zero address"); require(spender != address(0), "ZKSbaby: approve to the zero address"); _allowances[owner][spender] = amount; emit Approval(owner, spender, amount); } } 这个代码不能在zks上发行 zks 你要去安装依赖才可以 部署这里我就不写了网上有很多教学 我自己在Taiko测试链上发的大家做测试的时候可以去部署下
