教你如何在5分钟以太坊上发布自己的代币

该教程可以更好的让你体验以太坊网络

主要步骤：

提示：
1、安装Metamsk插件（申请账号，在测试网中获取一些免费的以太）
2、写一个实现ERC20协议代币合约的智能合约
3、将合约编译部署到以太坊的网络上（这里部署到Ropsten测试网，有钱的小伙伴可以尝试主网）
4、将你发布的代币导入钱包中

1、安装Metamask

这里省略Metamask的安装和获取免费以太的方法，百度一下就有教程了哦

2、写一个实现ERC20协议代币合约的智能合约MyToken.sol

pagma solidity ^0.4.16;
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 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 allowance
        allowance[_from][msg.sender] -= _value;
        _transfer(_from, _to, _value);
        return true;
    

    function approve(address _spender, uint256 _value) public
        returns (bool success) 
        allowance[msg.sender][_spender] = _value;
        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;
