本文主要是介绍从零教你学习BSC教程|BEP20|BNB Smart Chain|Bsc教程,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
一、安装环境
1、在chrome浏览器安装MetaMask插件
2、安装插件
安装方法,下载后解压,在浏览器输入chrome://extensions/,将安装文件拖拽进浏览器,即可安装
二、发布合约
进入到remix进行
在此是需要已经安装Chrome插件的
1、合约模版
pragma solidity ^0.4.16;interface tokenRecipient { function receiveApproval(address _from, uint256 _value, address _token, bytes _extraData) public; }contract TokenERC20 {string public name;string public symbol;uint8 public decimals = 18; // 18 是建议的默认值uint256 public totalSupply;mapping (address => uint256) public balanceOf; //mapping (address => mapping (address => uint256)) public allowance;event Transfer(address indexed from, address indexed to, uint256 value);event Approval(address indexed owner, address indexed spender, uint256 value);event Burn(address indexed from, uint256 value);function TokenERC20(uint256 initialSupply, string tokenName, string tokenSymbol) public {totalSupply = initialSupply * 10 ** uint256(decimals);balanceOf[msg.sender] = totalSupply;name = tokenName;symbol = tokenSymbol;}function _transfer(address _from, address _to, uint _value) internal {require(_to != 0x0);require(balanceOf[_from] >= _value);require(balanceOf[_to] + _value > balanceOf[_to]);uint previousBalances = balanceOf[_from] + balanceOf[_to];balanceOf[_from] -= _value;balanceOf[_to] += _value;Transfer(_from, _to, _value);assert(balanceOf[_from] + balanceOf[_to] == previousBalances);}function transfer(address _to, uint256 _value) public returns (bool) {_transfer(msg.sender, _to, _value);return true;}function transferFrom(address _from, address _to, uint256 _value) public returns (bool success) {require(_value <= allowance[_from][msg.sender]); // Check allowanceallowance[_from][msg.sender] -= _value;_transfer(_from, _to, _value);return true;}function approve(address _spender, uint256 _value) publicreturns (bool success) {allowance[msg.sender][_spender] = _value;Approval(msg.sender, _spender, _value);return true;}function approveAndCall(address _spender, uint256 _value, bytes _extraData) public returns (bool success) {tokenRecipient spender = tokenRecipient(_spender);if (approve(_spender, _value)) {spender.receiveApproval(msg.sender, _value, this, _extraData);return true;}}function burn(uint256 _value) public returns (bool success) {require(balanceOf[msg.sender] >= _value);balanceOf[msg.sender] -= _value;totalSupply -= _value;Burn(msg.sender, _value);return true;}function burnFrom(address _from, uint256 _value) public returns (bool success) {require(balanceOf[_from] >= _value);require(_value <= allowance[_from][msg.sender]);balanceOf[_from] -= _value;allowance[_from][msg.sender] -= _value;totalSupply -= _value;Burn(_from, _value);return true;}
}
2、进入编辑网站
代码不需要修改
点击“Deploy”按钮
3、提交
点击“Create”后,就可以看到MetaMask弹出的“CONFIRM TRANSACTION”的页面,这个页面是用来确认发送的,点击“CONFIRM”确认提交。
点击刚刚发布的智能合约地址,就会调转到区块链浏览器,耐性等待智能合约的创建。
下图则为你的合约地址,然后查看合约的具体信息
