基于ETH创建自己的代币

发行ETH代币

首先参考该文章 https://ethfans.org/topics/118， 且根据实际操作分享一下
当然首先要同步完区块，然后准备一点ETH（我是准备了0.02个，创建代币手续费+测试转账）。
文章中的：

这个部分所提供的代码已经不再试用，经过调整最后的代码为：

/*
This creates a public tradeable fungible token in the Ethereum Blockchain.

        /* if supply not given then generate 1 million of the smallest unit of the token */
        if (_supply == 0) _supply = 1000000;

        /* Unless you add other functions these variables will never change */
        balanceOf[msg.sender] = _supply;
        name = _name;
        symbol = _symbol;

        /* If you want a divisible token then add the amount of decimals the base unit has  */
        decimals = _decimals;
    }

    /* Send coins */
    function transfer(address _to, uint256 _value) public{
        /* if the sender doenst have enough balance then stop */
        if (balanceOf[msg.sender] < _value) require(balanceOf[msg.sender] < _value);
        if (balanceOf[_to] + _value < balanceOf[_to]) require(balanceOf[msg.sender] < _value);

        /* Add and subtract new balances */
        balanceOf[msg.sender] -= _value;
        balanceOf[_to] += _value;

然后这个位置：

不知道是不是币名相同的原因（没有测试），反正最好是一个没有出现过的代币名称否则会失败，已经有确认的但是查不到这个币，也没法转账，并且手续费建议控制在0.01左右个，不要太少了。

这个输入的密码是你创建第一个地址（Main地址）的时候输入的密码

下面的这个操作没有进行，自动就会生成出来，版本是0-10-0的Ethereum

然后就是一个弥天大坑，就是说在输入精度的那个地方，如果你输入的是8，那么你要发的一个币就应该是1后面8个0,这样才是一个币，我就比较惨了以为填多少就是多少币结果就发0.1个币…，其实不是的根据你的精度要在实际发币的后面加上这个精度的数量，然后测试了发送之类的没有问题。


然后我用了在上一篇博客中写的方法去扫代币 https://blog.csdn.net/Day_Day_No_Bug/article/details/90698141
也没有任何问题，成功的扫到了自己发行的代币

但是不要忘记了改扫块的合约地址，在上面博客中有提到如何改，本篇结束。
