使用 golang 将ETH账户的资产平均分散到其他账户

平时如果你需要把一个账户的eth打散到很多账户，其他账户批量操作的话，就需要一个个的发送，很麻烦，下面这段脚本可以把一个账户的eth打散发送到指定的很多账户
首先安装依赖插件

go mod init test
#复制下面代码放入 test.go 然后执行：
go mod tidy

如下代码展示如何将0xbf8B5bc7Ea580ca7cEDa5F79F6ef3362134fC695 账户的ETH平均分散到其他账户

package main

import (
	"encoding/hex"

	"math"
	"math/big"
	"sync"
)

var myAddress = "0xbf8B5bc7Ea580ca7cEDa5F79F6ef3362134fC695"
var rpcUrl = "https://eth-mainnet.public.blastapi.io" // RPC URL  如果地址不能使用了 请去 https://infura.io 注册账号获取免费的

var dispersion_accounts = []string{

func getClient() *jsonrpc.Client {
	mut.Lock()
	defer mut.Unlock()
	var err error
	if RpcClient == nil {

			panic(err)

	}
	return RpcClient
