aave在Goerli测试网络上推出了自家的Gho稳定币项目，支持存款，借贷，还款等交互。
Aave - Open Source Liquidity Protocol
Aave is an Open Source Protocol to create Non-Custodial Liquidity Markets to earn interest on supplying and borrowing assets with a variable or stable interest rate. The protocol is designed for easy integration into your products and services.
我们用代码的方式来交互下存款，python3代码样例，可执行代码:
注意: 执行前记得替换自己的私钥，默认存款0.01个

执行后打印交易hash, 去浏览器查询状态
回到gho dashbord，看到我们已经地址已经有存款了
