justSwap怎么发币,tron发币教程

tron发币很简单,而且比ETH和EOS更便宜,转账空投又便宜又快捷。

再加上可以直接在justSwap上币交易,实在是简单方便快捷的东西。

不过TRC20发币的教程比较少,这里写一个(虽然和ERC20高度类似,几乎90%通用)。

主要步骤:

  1. 安装Tronlink:
  2. 部署合约并广播
  3. 在https://tronscan.io登记发布一下
  4. 完成

1.安装tronlink

(https://chrome.google.com/webstore/detail/tronlink/ibnejdfjmmkpcnlpebklmnkoeoihofec)

这是一个google插件,tron钱包来的。安装完毕创建新钱包或者导入私钥

2.部署合约

首先检查一下你有没能量,部署合约需要能量。

没有能量就去抵押一点TRX或者租一点。价格很便宜,也就几块钱人民币的事情。

我这里租了10万能量就成功发了好几个合约了。

首先打开tron-ide。你喜欢自己部署环境也可以自己动手。

http://www.tronide.io/#ideVersion=v0.4.5&optimize=false&version=soljson-v0.4.25+commit.69a1e72.js

新建一个文件,打代码,这里有个简单的示例合约,只要改下面的币名和数量就完事了。

复制上面代码弄上去就好。

接下来编译一下代码。

首先点插件这里,激活一下部署和广播用的插件。

激活完毕多了几个图标,按照下图点。成功编译的话没啥错误就进行下一步。

之后按下图点击,就可以广播合约了。

tronlink会跳出来,让你确认签名,确认后给点能量,就完成了。

然后你可以去区块浏览器查看是不是成功了。

3.在https://tronscan.io登记发布一下

弄完了,但是没有币,很奇怪?

这时候在钱包按照合约地址添加资产就有了。

不过最好去tronscan登记发布一下。

点击通证录入

选TRC20,把你发的合约信息填上,此处有个需***的验证码。

提交了,你的币就很能很好的查询到了,也可以上传币的LOGO啥的。

4.完事,可以去空投发币。可以上justSwap圈钱了,祝大家发财。
