另外,你还需要一点以太币,大多数合约只需要价值不要1毛钱的以太币。如果你没有以太币,又不想到国外交易所折腾,可以选择用微信扫描下面的二维码直接在微信中购买:
创建账户并购买到1个以太币以后,钱包界面如下,创建新币合约我们要创建的第一个合约是一个代币合约。
1 S' Y& t. n; D/ r
以太坊生态系统中的代币可以代表任何可以交易的东西:币(coin)、积分、黄金证券、欠条(IOU)等。
4 G, {, Z( F9 o5 {9 A/ i% F
因为所有的代币都以标准化的方式实现一些基本的特性,这样意味着你自己创建的代币将于以太坊钱包、使用相同标准的任何其它客户端或者合约相兼容。点击红框中的Contract(合约)。, T) n( B; | l+ n. u, s9 L# T

如果代码编译成功,在左边将看到Pick contract,如下图:
" e5 ?, A8 `: J0 P# u
然后,选择MyToken选项,如下图:
然后,在右边更改系数,定制自己的货币。supply: 货币总量,name: 货币名字,symbol:货币符号,decimals:货币单位精确到小数点后几位。
下图定制的Shaopingcoin(少平币),总量10000个,货币符号:WL,货币单位精确到小数点后八位。根据自己的喜好,填写即可。 SELECT FEE(选择费用),左右拖动横轴选择支付多少手续费(这里就需要用到前面购买到的以太币了),越靠近右边,费用越高,完成合约的速度越快。例如,我选择了0.016131个以太币,大约需要30秒完成合约。完成后,点击DEPLOY(部署)。

点击DEPLOY后,自动转到如下界面,输入密码(即创建账户时设置的 密码),点击SEND TRANSACTION(发送交易)。
然后,会跳转到钱包主界面,你会看到下面红色方框中的信息,大约需要3-4分钟的确认时间,完成12个确认就可以了。
