之前面试题是用python写的，后来公司那边人说最好是用Golang实现

我对golang部署合约完全不懂，只能从0开始配置Golang开发ETH的环境

python实现：https://github.com/r4bbit2015/Eaam

需求：

1.部署合约Anyswapv6Erc20合约

2.调用InitValut设置Keystore地址

3.调用mint、调用swapout

4.获取swapout交易、输出交易内容、区块高度、区块时间戳

5.调用mpc函数查看mpc地址

1.配置go镜像

go env -w GOPROXY=https://mirrors.aliyun.com/goproxy/,direct

2.安装rpc

go get github.com/ethereum/go-ethereum/rpc

不能挂代理，不然报错

fatal: unable to access 'https://github.com/ethereum/go-ethereum/': Failed to connect to github.com port 443 after 6 ms: Connection refused
