Remix是一個基於瀏覽器的編譯器和IDE，使使用者能夠使用Solidity語言構建以太坊合約並除錯事務。

在上一篇文章已經成功的使用程式碼講智慧合約編譯並且釋出部署到了鏈上，可是在部署 發幣的智慧合約 不行，於是另找方法➡️remix

git clone https://github.com/ethereum/remix-ide.git

cd remix-ide

npm install   //可能會出錯多試幾次，網路問題。

sudo npm run setupremix  

npm run build

npm start

瀏覽器開啟： http://127.0.0.1:8080

編譯發幣智慧合約

將發幣的智慧合約 copy 進去 

部署合約

1.選擇環境為web3 Provider ，設定為我們自己鏈上的地址

2.選擇釋出合約的賬戶

3.配置資訊

結果

在下面我們還可以查詢某個賬戶對代幣，以及代幣對基礎資訊，使用者之間代幣轉賬等功能。
