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。$ x0 B" n2 w1 W
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。# ?2 \% G5 d- U; q( `- W% h
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)。* n1 Z0 {$ z; d4 A: T, Z6 |& s

如果代码编译成功,在左边将看到Pick contract,如下图:
: G2 y! g$ h X+ l. ?; S3 H
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。0 a. W: Q# @+ G, c8 s% ?4 T
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)。4 n6 A4 P3 @! f1 n% X

发送新创建的新货币进入SEND(发送)页面,在右上角的红色方框中输入收款者的账户地址。在AMOUT中填写发送的数量,在右边的红色方框中选择要发送的货币。左右拖动横轴选择费用,越靠近右边费用越高,处理速度越快。下图表示向0xba960dbedc4c2e0774729b2def16764592ced454地址发送10个ShaopingCoin,交易费用是0.00253625个以太币。点击SEND(发送)。

回到WALLETS(钱包)界面,会看到刚刚发出的记录信息。
收款者需要将新创建的币的添加到WATCH Token中才可以看到收到的币。收款者进入CONTRACT(合约)页面,点击WATCH TOKEN。发送者将创建的新币的合约地址通过聊天工具发给收款者。: Y& z# p3 ~8 i% _9 v
